You can buy luxurious rose seedlings at a more attractive price in the fall, when numerous exhibitions and fairs offer a huge selection of varieties. What is no reason to plant roses in September-October? At its core, autumn planting of roses differs from spring planting in only a few nuances. Simple rules and a few tricks will help to get healthy, strong plants that will start growing and will please the first flowers before planting in the spring.Rules for planting roses in the fall.
For the success of the autumn planting of roses, you need to create the conditions for only one, but critically important process - quality rooting of plants before freezing. And for this you need to take care of meeting deadlines, pre site preparation and simple landing procedure.
When is it best to plant roses in the fall?
Planting of ornamental plants, including shrubs in autumn, covers a fairly long period. In fact, roses can be planted from mid-August to the end of October. But planting dates are different for plants with open and closed root systems. And the risks over a long calendar period are far from the same.
Early planting in roses is extremely dangerous: if the buds wake up, the shoots begin to develop, an unripened bush may not survive the winter. A late landing puts the rooting process at risk.
Best landing time seedlings of roses with bare roots in the fall, they rightly call the period sufficient for their qualitative rooting, but without the start of active vegetation and the growth of young shoots. For each region, it is worth determining the dates individually, counting approximately 20-30 days before the first alleged freezing.
The best conditions for rooting roses - air temperature is about 10-15 degrees during the day and at least 5 degrees - at night.
Planting roses in the third decade of September and the first decade of October is the safest option for the middle lane. Under favorable weather conditions, this “pink” time can be easily stretched from mid-September to mid-October.
Roses with a closed root the system is planted to frost, but from mid-September, plants need to be cut and not allowed to grow new shoots, and from November to wrap. The optimal deadline is the end of August and the first decade of September, which allows the entire bush to ripen without scraps.
When buying at the end of October, you can plant roses in containers and keep them at a temperature of about 0-2 degrees until spring planting. In an extreme case, you can dig them obliquely on the hills in the garden into large trenches with a depth of about 40 cm and cover them with lapnik and snow.It is better to buy roses with an open root system for autumn planting just before planting.
The choice of seedlings of roses for autumn planting
With the onset of autumn, gardeners again have the opportunity to plant not only seedlings of roses with a closed root system (as in summer), but also ordinary roses with "bare" roots.
When choosing seedlings in autumn, follow the same rules as at any other time:
- check the frost resistance of the variety, its adaptation to the local climate;
- specify all the information regarding the cultivation of the variety: the conditions to which the plant is used, the care that it needs to reveal its decorativeness, whether (and how) to cover the rose for the winter;
- inspect the plants: the seedling should be with 2 to 4 skeletal shoots, with healthy shiny stems, roots and leaves, without signs of disease damage, traces of rot. For seedlings with open roots, it is worth checking the uniformity of root development, the presence of a large number of subordinate roots, their elasticity and condition - flexibility, cut; for roses in a container - soil condition and root coma density.
It is better to buy roses with an open root system for autumn planting just before planting. Even one day can be critical. Seedlings in containers can be bought in advance, providing plants with care for several days or weeks before planting.
For any roses, large enough planting pits are prepared with a depth and diameter of about 40 cm.

Preparing for landing and choosing a place
For planting roses, choose sunny, warm, protected from drafts and wind, ventilated, flat or slightly elevated areas with high-quality fertile loose soil, without the risk of dampness and wetting.
The fertile soil layer and its working depth for roses should be at least 40 cm. The optimal pH values are from 6.0 to 7.0.
Before landing, all necessary tools and equipment should be put in order, make sure their cleanliness and working condition.
But the main thing is work with soil, which includes two procedures:
- Site Preparation. For planting roses in autumn, a place can be prepared a few weeks before planting, if possible - a month or two. The work should include deep digging with the careful removal of rhizomes of weeds, debris, stones, the application of organic and mineral fertilizers or sand, peat to correct the quality and reaction of the soil. On depleted or neglected soil, a complete replacement of the fertile layer with a substrate of high-quality loam mixed with compost or humus in equal proportions is permissible.
- Landing pit preparation. It is carried out 1-3 days before disembarkation. For any roses, large enough planting pits are prepared with a depth and diameter of about 40 cm, if drainage is needed. When the soil is dense, there is a risk of waterlogging - the drainage is prepared from crushed stone, expanded clay or crumb brick - up to 70 cm in depth. At the bottom of the pit with depleted soil, organic fertilizers and a standard portion of full mineral fertilizers are additionally added. Strong watering 2-3 days before planting will create ideal conditions for roses.
If the rose is climbing and needs support, it is set before planting.
In order for the autumn planting of roses to be successful, you need to take care of the preliminary preparation of seedlings. Roses in containers are easy to prepare - they are watered a day or at least 12 hours before planting.
But with seedlings with open roots you need to work more carefully:
- Plants are examined, shortening the roots to a length of 30-40 cm and removing leaves, damaged and dry roots to healthy tissues.
- Shoots shorten to 2 to 3 buds (approximate height - 30 cm). If the bush is highly branched, leave 2-3 quality, strong, well-developed shoots, cutting extra branches at the base.
- If kidneys are visible below the site of vaccination, it is advisable to remove them to prevent overgrowth.
- Roses are soaked for a day or at least several hours before planting - in water, a weak solution of fungicides or root stimulants. And before planting, they are kept in an earthenware mash.
How to plant roses in the fall?
Root seedlings with an open root system
Planting should begin with loosening the soil at the bottom of the planting hole and pouring a small mound. The process itself is very simple:
- The sapling is established by evenly distributing the roots around the perimeter of the knoll and in no case bending them.
- Holding the stems strictly upright and gently pulling the seedling up, they add the substrate.
- The soil is carefully compacted along the perimeter of the planting hole, watching the depth: the place of budding should be buried to a level of approximately 5 cm.
- Landing is completed by abundant watering (from 10 to 20 liters of water in several runs). After watering, re-check the planting depth and add soil.
Unlike roses with bare roots, with such roses everything is very simple: plants are transshipped, carefully removed from the container and completely retaining the earthen lump. The level of planting is controlled by the root neck (it should be located at a standard depth of 5 cm). Watering is carried out according to the same rules.
What distance should be observed when planting roses?
Usually, when planting, observe the following distances between rose bushes:
- miniature and border roses are planted at a distance of 25 to 40 cm from each other;
- park and bush roses are located at a distance of 50 cm for floribunda and hybrid tea varieties, up to 1 m for some English roses (depending on the height and spreading of the bush);
- ground cover roses are planted at a distance equal to half the estimated diameter of their crown;
- standard roses are planted at least 1 m from other large plants;
- for climbing roses, the standard is at least 1 m distance to neighbors.
Caring for roses after an autumn planting
Immediately after completion of planting, roses are usually mulched with peat, compost and other materials. This helps not only to keep the soil moisture more stable, but also protects the rose from unexpected sudden changes in autumn weather. However, today, mulching has a much more effective and fashionable alternative.
Hilling is one of the main secrets of quickly adapting a rose and reducing the risk of seedling loss. Many garden centers recommend hilling immediately after planting, even when planting in the spring. It accelerates rooting and minimizes the influence of negative weather factors - from temperature to exposure to the sun.
With the classical approach, the hilling is carried out after frost, but it is better not to pull and carry out this procedure after planting. Roses are spudded so that only the top of the shoots remains above the knoll with a height of 10 to 20 cm.
As a rule, during the autumn planting of roses, watering is carried out only in extremely dry weather.
If varieties need protection for the winter, occult roses are covered with air-dry method after the arrival of frosts by a standard method or they comply with the recommendations received when buying a plant.
