Growing Tips

Roses like clay soil, although they may be grown successfully in a variety of soils, as long as a good amount of organic matter is worked in. Very heavy soils are best improved by replacing at least half with sandy loam or sharp sand; also gypsum and/or perlite may be added.

Planting Time

Spring planting is best done as early as possible, and as soon as the frost is out of the ground; a newly planted rose establishes itself quickest in the cool moist spring soil, rather than in May, when the air is often hot and dry. Also, the longer growing period will produce more and better blooms.

Planting Site

Generally, roses do best in full sun, but a minimum of 4 to 6 hours sunshine daily, is satisfactory. Competition from tree roots should be avoided, as also badly drained areas. In cold climates, roses should be planted in the ground; in raised beds or containers above ground level, the plants will be more readily winter-killed.

Type of soil

Roses like clay soil, although they may be grown successfully in a variety of soils, as long as a good amount of organic matter is worked in. Very heavy soils are best improved by replacing at least half with sandy loam or sharp sand; also gypsum and/or perlite may be added.

Soil preparation

If possible, it's best to do this some time prior to receiving the plants. The deeper the soil is prepared the better, even to a depth of 18 to 24 inches. If obtainable, cow manure is best to mix with the soil in liberal quantities. Well-rotted horse or sheep manure can be used too. With or without manure, peatmoss is always good to mix in liberally throughout the bed; when planting a single bush, a climbing rose for instance, the mixing in to the equivalent of a 2 to 3 gallon pail of peatmoss is good practice. In addition, bone meal or superphosphate at a rate of 5 lb per 100 sq. ft. of bed, or a double handful per plant is advisable. We need not fear making it too rich, because roses are heavy feeders, and organic matter adds to the moisture retaining quality of the soil.

Planting distance

Hybrid teas, Grandifloras and Floribundas at 18 to 24 inches apart. Climbers 5 to 6 feet and even up to 8 feet for the more vigorous kinds. In mild climates, the above distances, especially for bush roses, would be greater.

Planting

To prevent the finer roots from drying out, especially on a sunny windy day, it's advisable to have the plants in a bucket of water while planting. The holes should be dug large and deep enough so that the roots spread out freely; they should not be bunched up in a narrow, shallow hole. The plant is then held in the right position, with the union (or "crown") at or one inch below the surface. Fine soil, preferably a mixture as describe above, is then used for backfilling the hole. This loose earth should be firmed down with one's feet up to more or less two-thirds of the depth; the remainder of the hole is then filled with water, and after this has soaked away, backfill the rest of the hole. When planting bareroot roses in late spring, it's best to mound each plant with soil for about 2 weeks to prevent the branches from drying out on sunny days.

Delay in planting

It's of utmost importance not to let plant roots dry out before planting. Ideally, roses should be planted immediately when received; if this is not possible, then it's best to store the plants in a closed plastic bag in a cool frost-proof place. In case the branches look shriveled, the plants may be immersed in water until the bark looks smooth again; they should not be left in water longer than is necessary though. If planting has to be delayed for a considerable time, then it's best to bury the plants in moist earth in a slanted position, leaving only the branch tips sticking out.

Pruning at planting time

The tops should be cut back severely: only 3 strong branches from the base need to remain, and it is best to cut these back to 4 or 5 inches above the ground. This severe pruning gives the plant a better chance to establish itself, and once new roots are developing, strong growth will come forth. When planting in fall, the plants need not be cut back much; the actual pruning as explained, should be done the following spring. The roots may be cut back an inch or two, and excessively long ones further. Broken ones should be cut off.

Spraying or dusting

It should be kept in mind that a plant which receives good nourishment and is looked after well, is the least prone to diseases. It's good practice to spray or dust regularly from the time the first leaves start to develop.

Fertilization

Commercial fertilizer, other than bone meal or superphosphate, should not be used at planting time, unless it's a "plant starter" formula, in liquid or water soluble form. Chemical fertilizer should be used strictly in accordance with the directions on the package. Once the roses are established and growing well, such fertilizer may be spread on the surface; then to be raked or hoed in, and followed up with a soaking if the ground is dry. Granular fertilizer should not be applied after the end of July; liquid fertilizer may be used till mid-August, though moderately! Late season fertilization with nitrogen should be avoided as it leaves the plants with soft growth when winter sets in, and they get more readily winter-killed. Potash and superphosphate can be applied in late summer, to help late growth harden off before freezing weather sets in.

Watering

Even though roses like good drainage, they do need a lot of water during the growing season. During prolonged periods of drought they should be thoroughly soaked, once or maybe twice a week, depending on the moisture holding capacity of the soil. In most cases it's best to water in the late afternoon or early morning. To avoid spray or dusting chemicals from being washed off the leaves, the water should be applied straight to the soil around the plants.

Pruning established roses

In our northern climate, Hybrid teas, Grandifloras and Floribundas should be pruned back in early spring to approximately 4 to 6 inches above ground level. The strongest branches only, should be left to develop. As for pruning others, see the next paragraph.

Please note

that non-recurrent varieties do not usually bloom the first season following planting. Depending on frost-die-back, they require very little or no pruning then. As the plants grow older, the removal of older wood suffices; this applies to Hybrid PerpetuaIs, Climbers, shrub roses, and many of the Antique roses.

Suckers

(wild shoots) may occasionally develop from at or below the bud union. These should be removed entirely at the point of origin; as young shoots they can usually be wrenched off. Care should be taken not to leave the slightest stub on the rootstock, other-wise all the more suckers will sprout, which will be all the more difficult to remove later.

And please ...!

Do not pay attention to the non-sensical assertion that seven leaflets per leaf is indicative of a wild shoot. Many of the old varieties have seven and more leaflets per leaf, and you may even notice seven leaflets on some of the modern cultivars.

An ingrained idea?

It has been said of our roses that "the roots could not be spread over the cone in the bottom of the hole." That would be difficult indeed; but then, there's absolutely no need for that anyway How about "ready to plant" packaged or potted roses: it would have been impossible to spread those roots over a mound, regardless of the type of rootstock.

Delay in transit

can cause the plants to sprout when they have been exposed to heat. If the roses have broken dormancy to the extent that new growth has developed, then it's best to cut it back to one-eight of an inch. New (white) roots will probably have started too then. When planting, assure that the roots are wet; never leave roots exposed to the air, as the fine-ones dry out quickest, and they're the most important to get the plants off to a fast start. The best is to "puddle" the roots in a soupy mud, with a solution of "plant starter" (root-promotor) added. Hill the plants up with soil, leafmold or other suitable organic matter (but not manure or mushroom compost unless really old), which can be levelled after 2 to 3 weeks.

Please note:

In a milder or more severe climate, some of these tips would be subject to adjustments.
