FREQUENTLY ASKED QUESTIONS

Will roses grow in shade?
Roses will not grow in full shade, but some roses may grow in partial or long shade. Roses will grow if they receive at least 5 to 6 hours sun each day -- of course, all day sun is preferred. If it is a choice between all morning sun or all afternoon sun, then morning sun is preferred.

How much sun do my roses need to grow?
Roses need at least 5 to 6 hours of sun each day to grow, but they prefer all day sun.

Can I plant roses next to the foundation of my house?
Yes. It's best to keep them at least 2 to 3 feet away from the house. Also, remember that near the house foundation is usually a very dry location as well as a hot one, so water more heavily and more frequently.

Must roses have good soil drainage?
Yes. Most soils will drain well enough for good growing conditions. It is only in the very heavy tight clay soils through which water cannot drain away, that drainage for your roses is needed.

Can I improve the poor soil on my property sufficiently to grow roses?
Yes. The only important difference between good soil and poor soil is that good soil contains sufficient organic matter and fertility, drainage, and poor soil does not. Poor soils can be improved sufficiently by making a mixture of 1/4 to 1/3 organic matter. (Peat moss, rotted manure, humus, compost) and 3/4 to 2/3 existing soil plus 4 pounds of a well-balanced fertilizer, for each 100 square feet of rose bed you are preparing. All this should be mixed thoroughly together to a depth of 14 to 18 inches.

Can I plant roses too close together or too far apart?
Yes. Spacing roses from 20 inches to 30 inches apart produces the best results. Wider spacing than 30 inches make the plants stand out as individuals and you lose the intimate mass effect a rose garden should present. Closer spacing than 20 inches will crowd the plants and restrict their growth.

Can I mix hybrid tea, floribunda, and grandiflora roses in the same bed?
Yes. An excellent effect can be achieved from mixing different types of roses in the same bed if you keep the lower growing varieties to the outside of the bed and the taller ones to the center and background where they will not be hidden.

How do I prune roses?

Must roses be planted in beds by themselves as in a rose garden?
No. Roses may be used extensively in landscaping to produce a very colorful and interesting effect.

Are climbing roses restricted to use on fences, trellises and arbors?
No. Climbing roses may be used to cover many things such as walls, buildings, tree stumps, and steep slopes for ground cover. They may be trained to a post to create a pylon effect and some of the less vigorous varieties may be pruned to form a pillar or large shrub effect.

Can tree roses be grown successfully in cold climates?
Yes. If other roses can be grown there successfully, then tree roses may also be grown. An important item to remember is that in areas where the temperatures fall below 10°F in winter, tree roses must have careful winter protection by wrapping them with insulating material to protect them from the cold and wind. In the colder areas where the temperatures fall below zero, the only adequate protection for tree roses is to lift them in late fall before very severe freezing weather and bury them in a trench covering them completely with a foot or more of earth.

Must I use hedge type roses only to create a hedge?
No. Hedge type roses may be used in most all locations and most all types of roses may be used to create hedges. The only limiting factors are what you desire from the rose, the location in which you plant it and the care it receives.

Is an exposed, wind swept location a detriment to growing roses?
Yes, a wind swept location is usually a dry one in summer and a cold exposed one in winter. Some shelter is desirable provided it does not also carry with it too much shade or root competition from other plants.

Is there an advantage to planting roses in Spring?
Yes, but it really depends on your climate. Spring is the time of year when plants awake from dormancy and begin to grow. It is the time of year when we are most tired of winter and get the urge to plant things and see plants begin to grow. Roses planted in spring begin growing within 2 to 3 weeks after planting and about 6 to 8 weeks more they will be in bloom. Spring planted roses have all summer to become established and are better able to go through the winter without injury.

Is there an advantage to planting roses in Fall?
Yes. The weather and soil conditions at planting time are usually better in the fall than in spring. The soil is usually wet and muddy and the weather unsettled in spring. A rose planted in the fall is usually somewhat established by spring and will bloom earlier in the season. Rose availability, however, is more limited in the fall. In some we offer container roses that can be planted throughout the season. Check "Our Roses" and when you see the pot symbol that will indicate that the roses are available in pots.

You can easily contact one of our customers by clicking here. Contact them to inquire about their Star® Rose availability.

Is there an advantage to planting boxed or package roses?
It depends. Boxed and packaged roses are available earlier in the season. They may be successfully planted in quite cold weather, as they have not yet begun to grow. They may also have a slight price advantage and they make wonderful gifts for Mother's Day, Birthdays or house warming gifts.

Is there an advantage to planting potted roses?
Yes. The potted rose has begun to grow when you receive it and is often in bud and bloom, giving you the advantage of a started plant. The potted rose can be successfully planted late in the season or even during the summer when dormant roses are no longer available, or practical to plant. Potted roses are also a little easier to plant, as there is no concern about getting the earth firmly placed between and under the roots, because the roots are encased in a ball of earth.

Should I mound the earth over the top of the potted rose when I plant it?
No. If the potted rose has begun to grow when you receive it, mounding is unnecessary. If there is no growth on the potted rose, and there really should be when you purchase it, then a mount of soil 8 to 10 inches high over the stems of the rose would be advisable. Check in our How to Plant a Star for additional planting information.

What size should be rose beds be?
Rose beds should be at least 3 feet wide so that 2 or more rows of roses may be planted to give sufficient volume of color for the most pleasing effect.

Is there an advantage to preparing a rose bed ahead of planting time?
Yes. The soil in a rose bed prepared at least 3 to 6 weeks ahead of time has a chance to settle down before planting so that there is less settling afterward and less danger of the plants being too low later on. Also, the soil will be in better condition and the fertilizer more diffused in the prepared bed. A third advantage is that with bed preparation already completed, the planting can be done more quickly which is very essential.

Should I plant dormant roses as soon as I receive them?
Yes. The sooner you plant roses after you receive them, the better they will grow. If you cannot plant the roses as soon as you receive them, they can be stored in a cool place where they will not freeze for several days. Do not open the box until you are ready to plant.

Can I get too much organic matter in the soil preparation of a rose bed?
Yes. This, however, is seldom the case as usually too little organic matter is used. Amounts up to 50% organic matter can be used. More than that amount would make the soil too light or porous.

Can I use too much fertilizer in planting roses?
Yes. This is a common fault. Do not use more than four pounds of fertilizer per 100 square feet of rose bed area and then mix it thoroughly with the soil to a depth of 15 to 18 inches. Preparation 3 to 6 weeks ahead of planting will also reduce danger of fertilizer injury.

Can I prepare individual holes for each rose 18 inches wide and 18 inches deep instead of a whole rose bed?
Yes. However, complete rose bed preparation 18 inches deep is better.

Is it essential to water a newly planted rose heavily at planting time?
Yes. A heavy application of approximately a bucketful of water applied to the rose when the hole is about 2/3 filled with firmed earth is usually sufficient. It helps to settle the earth and moisten it thoroughly around the roots of the rose.

Must earth be mounted over the tops of dormant roses as soon as they are planted?
Yes. It is extremely necessary to mound earth over the tops of newly planted roses in spring or fall to a height of 8 to 10 inches. The mound should remain till the new growth shoots are about an inch long in spring when it should be removed.

Should I wait till I see insects and diseases to begin to spray or dust my roses?
No. It is very important to prevent insects and diseases in your roses by beginning to spray or dust, both newly planted and established roses as soon as growth begins and the little leaves are about 3//4 inch long. Use a multi-purpose rose spray or dust once or twice a month until frost in the fall.

Should I prune my roses each spring?
Yes. For best results, cut back Hybrid Tea, Floribunda, and Grandiflora roses to between 10 to 18 inches from the ground. Remove all winter injured or damaged wood. Prune climbing roses only as needed to control their size. Remove the older wood. Prune sparingly as the top is needed for bloom. For more information see How to Prune a Rose.

Should I coat the ends of cut off canes with a cane sealer or tree wound dressing?
This is not necessary but it could help prevent the entrance of stem borers in the rose canes.

Should I feed my established roses more than once each season?
Though this is not essential in good soils every year, established roses can be fed up to 3 times a season. The first feeding of 1/2 cup per plant of a well balanced fertilizer should be applied any time after the roses have gone dormant in late fall or early winter and before March 1st in spring. This gives the fertilizer an opportunity to penetrate deeply into the soil so that the roots can absorb it when the rose begins to grow in spring. The second feeding should be made as the rose finishes its spring bloom and the third feeding in late July or early August. The second and third feedings should be 1/4 to 1/3 cup of fertilizer to each plant. If possible, cultivate the fertilizer into the soil around the rose and water it thoroughly to assist in making the fertilizer readily available to the rose.

Should I feed newly planted roses as heavily as established roses?
No. Newly planted roses should be fed only once after planting the first season. One fourth to one third of a cup of fertilizer per plant added when giving the established roses their third feeding in late July or early August is sufficient.

Can I overfeed my roses?
Yes. Overfeeding roses is a very serious offense and in extreme cases, can cause them to die. If the above schedule is followed, it is unlikely that you will overfeed your roses.

Should roses be watered during dry weather?
Yes. Like many vigorous ornamental plants, roses need quite a quantity of water and in dry weather the gardener must supply this. A thorough soaking once a week when the rains are not sufficient is the better procedure. Permit the water to run slowly into the rose bed and to penetrate to a depth of 15 to 18 inches. Keep the water off of the leaves of the roses.

Does mulch help to conserve the moisture in the garden?
Yes. A 2-inch layer of shredded bark, cocoa bean hulls, etc. Over the rose bed will help a great deal in conserving moisture, eliminating weeds and relieving the necessity for cultivating.

Should the bloom be removed from rose plants as it matures?
Although this is not necessary, it will encourage more blooms on Hybrid Teas, Grandifloras and Floridundas. If spent blooms are not removed, a great deal of strength which could produce more blooms is lost in producing the rose seed which follows the bloom and which is of little or no value to the rose gardener. It is not practical or necessary to do this with our Climbers, Meidiland Shrub Roses, or Landscape Roses.

Should roses be pruned or cut back during the summer?
No. Cutting back rose bushes in summer will weaken them, as they need all the top growth they produce as the food of the rose is manufactured in the leaves or top of the rose. Some limited pruning may be done if a plant needs to be restricted due to its location. Also, June blooming Climbers may be cut back just after the bloom to control the plant.

Should roses be sprayed during hot weather?
Yes. Insects and diseases do not relax in hot weather so spraying is advisable if the plants are to be kept free from pests. Avoid using sulfur or Karathane in hot weather (temperature above 75 to 80 degrees) for mildew control.

Can I control mildew in hot weather without using sulfur or Karathane?
Yes. Light infestations of mildew and other fungal diseases are generally easily controlled using an all-purpose fungicide containing funginex.

Can Japanese beetles be controlled?
Yes. Japanese Beetles can be controlled but not completely eliminated. Regular spraying with "Sevin" will control most beetles. The use of biological controls such as the "Milky Spore" is also beneficial, to control the grub stage of the beetle.

Can I eliminate blackspot from my roses?
The best way is to plant varieties that are naturally resistant to disease if you live in a heavy blackspot area. Also, spraying with a general all-purpose fungicide 1-2 times per month will keep your plants clean.

Is it essential to spray for spider mites on a preventive basis?
Yes. Spider mites are so small that most gardeners do not realize that they are present till the damage is done. In warm dry weather, mites develop quickly. Spray every two to three weeks with a general-purpose insecticide.

Is a multi-purpose spray effective against all the above-mentioned pests?
Yes. A multi-purpose spray containing the right materials and conscientiously applied is effective in controlling rose pests.

If my roses have been defoliated (they don't have any leaves) badly due to neglect during the summer, should I feed heavily to encourage foliage in the fall?
No. This is very detrimental as the new growth, is can also injure, or weaken the plant.

Are the heavy growth stems that come from the base of the rose in late summer and early fall "wild" or "sucker" growth?
No. These are usually new and good canes for your rose. If they harden off sufficiently before cold weather they are fine new canes that should be preserved. If the shoots come from below the knuckle or bud union, they are "wild growth", or suckers and should be removed.

What is "wild" or "sucker" growth?
These are shoots or branches of the under stock that begin to grow below the bud union. If you notice this sucker growth do not cut or prune it, you must pull it from point where it originates from he plant.

What is "wild" or "sucker" growth?
These are shoots or branches of the under stock that begin to grow below the bud union. If you notice this sucker growth do not cut or prune it, you must pull it from point where it originates from he plant.

Are all stems that contain leaves composed of seven leaflets "wild growth"?
No. Almost all roses will have leaves composed of 3 - 5 - 7 - and even 9 leaflets. The growth must come from below the knuckle or bud union to be "wild" or "sucker" growth.

If I find growth coming from below the knuckle or bud union, should I cut if off?
No. Cutting off "sucker" or "wild" growth does not remove the source of the trouble and often causes in to grow that much more vigorously and instead of one shoot when cut back, often two or more shoots will grow out. The proper way to remove a sucker growth is to remove earth carefully from the base of the plant until you get down to where the sucker originates from the root of the rose. Then actually tear or gouge the sucker out of the root so that you remove the bud from which the sucker originated.

Is a dormant spray of lime sulfur of value to the roses?
Yes. A dormant spray of Lime-Sulfur applied after the roses have become dormant in fall or before they begin to grow in spring can, to a great degree, eliminate disease and insects that "winter over" on the plant. This is especially worthwhile if stem canker is a problem in the garden. The one caution is applying dormant spray is that the temperature must be 40 degrees or higher for 3 to 4 hours after the spray is applied.

Is it desirable to cut back bush roses in the fall before winter arrives?
Yes. There are several benefits derived from cutting bush roses back in the fall to a height of 2-1/2 feet especially in areas that normally receive a great deal of snow, sleet, and heavy winds. Cutting the stems back to 2-1/2 feet will remove the brushy, twiggy top growth that normally collects and holds snow and sleet that normally causes broken stems over winter. Removing the twiggy growth also reduces wind resistance and the whipping and loosening of plants from brisk March winds. Where snow, sleet, and wind are not a problem, it is not essential to cut back in the fall.

Should I cut my climbers back in the fall?
No. Pruning climbers is quite different from bush roses. June blooming climbers such as Paul's Scarlet, Dr. Van Fleet, Spanish Beauty, etc., may be cut back immediately after they bloom. The growth they make that summer will produce bloom the following spring. Cutting back in fall would mean no bloom in spring. Repeat and everblooming climbers should never to cut back severely unless the gardener is willing to sacrifice bloom for a year or more. The better plan is to thin out the repeat and everblooming climbers, removing the very old and unproductive wood. Also, in removing bloom from this type of rose, do not remove long stems as the repeat bloom often comes from these stems.

Can climbers be trained in any particular manner to encourage bloom?
Yes. Train the canes out in a horizontal manner along a fence or support parallel to the ground. This encourages more bloom when training them in a vertical manner.

Is it essential to cut back the hedge roses each year?
No. Hedge roses will bloom better if they are not cut back each year. Moderate pruning may be done each year to keep the hedge within the desired bounds.

Is it necessary to protect hedge roses over winter?
No. Hedge roses are hardy without protection in most climates.

Is winter protection necessary in the more temperate areas where the temperature seldom, if ever, falls below zero?
No. If roses are properly maintained, sprayed or dusted carefully, and disease and insect injury prevented, roses are hardy to several degrees below zero. If they are neglected and are weak when they go into the winter, they should have a mound of earth at least 8 to 10 inches high placed over the crown of the rose and up into the stems.

If roses have been growing in one location for some time and begin to deteriorate, can they be revived?
Yes, usually roses can, and will usually do well in the same bed for years and years. Usually such a condition has been brought about by a deterioration of the soil in the rose bed. The first step should be a complete soil test in which you learn the Ph of the soil as to whether lime is needed. You should also learn whether additional organic matter is needed and this is very important as organic matter can decompose and disappear very readily and if not replaced regularly, causes a serious detriment in the growth. You must also learn the level of fertility of the soil in essential nutrients, nitrogen, PhosPhorus, and potash as well as the minor elements.

A. When the status of the soil has been determined, steps may be taken to correct existing problems. If complete re-preparation of the soil is needed, it may be done a small section at a time and the roses transplanted into the newly prepared area directly from an unprepared area. It is also a good plan to discard any very poor plants during the transplanting process and replace them with new ones. Keep in mind that when transplanting the existing roses, they should be cut back, all poor or affected growth removed, and that they should be replanted just as a new rose.

B. The assurance of success of the project depends greatly on the program of maintenance that follows the transplanting. Regular preventive spraying, watering, feeding, etc. Are very necessary to give the ultimate in results.

Is calcium, as found in lime (Ca Co3) necessary to roses?
Yes. Calcium is necessary to the healthy growth of practically all plant life. However, it is a mistake to add lime to a soil without first learning what calcium is needed and also what the Ph of the soil is, too low (acid) will need to be corrected. Lime raises the Ph value of the soil and if sufficient lime is added, will change a soil from acid to alkaline. Roses enjoy a neutral (Ph 7.0) to slightly acid (Ph 6.0) soil reaction. They will tolerate quite a variation in the soil Ph but will tolerate a greater degree of acidity than alkalinity.

Can I add calcium when needed in the soil without affecting the Ph of the soil?
Yes. Gypsum (Calcium Sulfate) will supply the calcium without changing the Ph.

If one or more individual elements of fertility are needed to correct a deficiency, can I add these elements without using a balanced commercial fertilizer?
Yes. Individual materials such as Ammonium Sulfate or Calcium Sulfate for nitrogen, SuperPhosPhate for PhosPhorus, and Muriate of Potash for potassium.

Is manure beneficial to roses?
Yes. Manure and especially aged cow manure is beneficial to roses but it is a mistake to rely on it as the sole food for roses as it is not a completely balanced food.

If roses are growing vigorously and producing a great deal of foliage but few blooms, can this be corrected?
Yes. If the variety is normally a good bloomer, this condition is usually attributed to an over-abundance of nitrogen.

Can "weak neck" (the inability of the stem to support the bloom in an upright position) be corrected or aided?
Yes. If this is not an inherent characteristic of the particular variety, the addition of PhosPhorus to the soil can aid in strengthening the stems. Also make certain that the roses are receiving sufficient sun as shade can also cause weak stems.

Can "weak neck" (the inability of the stem to support the bloom in an upright position) be corrected or aided?
No. This is often a natural characteristic of the variety of rose. Also, this condition is more prevalent in the cool weather of Spring and Fall.

Can I transplant old established roses successfully?
Yes. If the transplanting is done while the plants are dormant in late Fall or early Spring, it is relatively easy. The plants should be cut back at time of transplanting to 12 to 15 inches and handled as one would a new plant.

Is it injurious to put manure against the stems of a rose?
Yes. Manures against the stems of a rose can help create a fungus in the stems of the rose causing a deterioration or dieback.

Is there anywhere in the USA that roses cannot be grown?
No. Given proper preparation and adequate maintenance, roses will grow anywhere in the USA where the sun shines at least 5 to 6 hours per day.

Are Miniature roses really roses?
Yes. They are tiny roses, having been created through hybridizing the Rosa Chinensis Minima, a dwarf strain of rose from the Orient.

Are Miniature roses hardy out-of-doors?
Yes. They are hardy out-of-doors in locations where other garden roses will grow.

Can Miniature roses be grown indoors in pots successfully?
Yes. If Miniature roses are given sufficient humidity, light, and soil moisture, and are not subjected to excessively high temperatures, they are relatively easy to grow.

Can Miniature roses be grown in porch boxes or window boxes?
Yes. If given sufficient care, Miniature roses will do well in porch or window boxes.

Do Miniature roses make good plants for borders or edgings to gardens?
Yes. There distinctly dwarf habit of growth (10 to 15 inches height) makes them ideal for edgings or borders.

Are Miniature roses successful as rock garden plants?
Yes. Their dwarf compact nature as well as all season bloom makes them ideally suited to rock garden planting.

Are Miniature roses everblooming?
Yes. Miniature roses are everblooming in the same sense that other garden roses are everblooming.

Are Miniature roses available in the various typical rose colors?
Yes. Miniature roses are available in the usual rose colors, shades, and blends of color.

Do Miniature roses need spraying or dusting?
Yes. For best results Miniature roses should be sprayed or dusted regularly once or twice a month.

Is my regular rose spray or dust suitable for use on Miniature roses?
Yes. A multi-purpose rose spray or dust or their various components may be used safely and effectively on Miniature roses.

Is it necessary to make any special soil preparation for Miniature roses other than my regular rose soil for outdoor planting?
No. Miniature roses may be grown in any properly prepared rose bed containing a mixture of 1/4 to 1/2 organic matter and the balance the existing soil.

Is this same mixture of soil suited to pot growing of Miniatures indoors?
Yes. This would be especially true if the soil used was of a sandy and gravelly nature. However, if a very heavy clay soil were used, then equal parts of soil, coarse sand, and peat moss would make a better mixture.

Do Miniature roses require much water out-of-doors in the ground?
Yes. Out-of-doors in the ground, due to their relatively shallow root systems, they need frequent and careful watering to prevent drying out.

Do Miniature roses require much water indoors in pots?
Yes. Correct watering, along with sufficient light, is the most important single item in the maintenance of Miniature roses indoors. While the soil should not be kept soggy wet, it should not be permitted to dry out badly and certainly not for any extended length of time. If kept dry for more than a day, the rose can be badly injured, if not killed completely. A daily check on soil moisture is advisable. If course, the larger pot in which the Miniature is growing, the less chance there is for its drying out badly. Then too, the higher the organic content of the soil, and the higher the humidity content of the air in the home, the less chance there would be for drying out and injury.

Is high humidity an important factor in successful indoor growing of Miniature roses in pots?
Yes. High humidity is on of the essential elements to success with Miniature roses indoors. Dry air, especially when it is also accompanied by high temperatures, will dehydrate the tops if the Miniature roses and cause the foliage as well as the bloom buds to shed from the plant.

Do Miniature roses require as much fertilizer as the larger bush type garden roses?
No. Miniature roses enjoy frequent but relative light feeding both indoors and out-of-doors. If soluble fertilizers are used, they should be applied at the manufacturers recommended strength for potted plants. Each month to 6 weeks, the soil in the pot or the soil around the plant out-of-doors should be thoroughly moistened.

Does the Miniature roses need protection out-of-doors over winter?
Yes. In sections of the country where the garden roses need winter protection, it would be a good practice to protect the Miniature rose out-of-doors also. They can be protected the same way as their larger relatives.

Should Miniature roses be cut back each Spring?
Yes. They should be cut back to about 4 to 6 inches from the ground and all dead or injured wood removed. It is also advisable to remove any very slender twiggy growth at the same time. This should be done in early Spring just as growth is about to begin.

Can Miniature roses be grown outdoors in Summer and then be brought indoors for Winter?
Yes. They may be lifted from the garden in late Fall or early Winter after they have been dormant for a month to 6 weeks. Carefully pot them in a large pot and with well-prepared soil. Water them thoroughly and gradually subject them to the warm indoor temperatures rather than bringing them from the cold out-of-doors to the warm indoors. Then follow the indoor culture.

Are Miniature roses available in bush, tree, and climbing forms, just as the larger roses?
Yes. Miniature roses are available in all three forms and each one retains its Miniature characteristics.

Are the trees and climbing forms hardy out-of-doors?
Yes, they are somewhat hardier than the larger roses of the same type.

Are the maintenance requirements for the growing of the Miniature climber and tree rose the same as for the bush form?
Yes. Use the same culture for all three types.

Are Miniature roses of value as cut flowers?
Yes. Miniatures make excellent arrangements. They last exceptionally long after they are cut.

Are Miniature roses a relatively new creation in the horticultural world?
No, the older types of Miniature roses were known as early as 1800 when they were brought to England aboard the old English trading schooners from the Orient. The modern Miniature on the market today came about around 1930.
