Roses - decoration of any garden from June to October. To protect their beauty from frost, you need to know the features of caring for roses in the fall and preparing for winter. Help in wintering is especially needed varieties of roses, bred recently and flowering continuously all summer. Varieties that bloom once, have time to adapt to the change of season.
How to slow down the growing season
For a good winter, the plant must accumulate nutrients in the fall and go into a state of rest. A decrease in temperature and a reduction in daylight hours will signal a winter coming for the rose, and changes in autumn care and preparation for winter will help rebuild biological processes. August - the month in which the preparation of roses for the winter season begins.
Important! A sign of active growth is a reddish hue of sprouts. In this case, the plant is not ready for wintering.
Watering reduction
In August, reduce the amount of water, and from the beginning of September, watering roses stopped. If the weather is very hot and arid, the cessation of watering is transferred to the end of the month.
In general, dry land is more suitable for hibernating roses than saturated with moisture.
Fertilizer change
Since August, they stop making nitrogen fertilizers that help abundant flowering, instead they make root dressing with potassium-phosphorus additives. This is another important nuance in how to care for roses in the fall.
During this period, it is recommended to conduct 2 dressings.
For the first in 10 liters of water dissolve:
- boric acid - 2, 5 g (can be replaced by brown - 3.5 g);
- potassium sulfate - 10 g;
- superphosphate - 25 g.
- water - 10 liters,
- superphosphate and potassium sulfate - 15 and 16 g, respectively.
Abstaining from trimming
In mid-September, cutting off faded buds is stopped. At the same time unopened buds that are smaller than a pea in size are torn off. The remaining buds are allowed to ripen and form seeds.
Important! The ripening of seeds in uncut buds accelerates the ripening of shoots and preparation for winter.
How to prepare roses for winter
It is important to help the plant gradually go into a state of rest and create conditions for protection against severe frosts, pests and diseases. At the same time, it is better to check all the preparatory procedures with the weather forecast, since in different years the seasonal cooling occurs in different periods.
Learn how to avoid dangerous mistakes when growing roses and protect your beloved.
Weeding
Loosening the soil is stopped in September. Otherwise, the shoots that are in the resting stage may begin to actively develop.
Copper Oxide Treatment
Treatment with a fungicide is carried out before hilling, in dry, warm weather, following all precautions. Previously, at a height of 40-50 cm, all the leaves are removed from the plant.
Copper oxychloride is sprayed to disinfect the bark and prevent many shrub diseases. The most famous of them are scab and powdery mildew.
Did you know? In aromatherapy, the smell of roses is used as an antidepressant and sedative.
Hilling flowers
Shrubs pile up before the first frost, since the movement of the juices in the plant has not stopped yet and the stem may crack from frost. A hill 30-40 cm high is piled around the stem. The mixture for hilling should be dry, it consists of ground with the addition of sand, sawdust, before hilling the ground around the root can be slightly powdered with ashes.
Trimming for the winter
Pruning and removal of leaves carried out in late October.
Processing of roses in the fall before shelter for the winter combines 2 types of pruning:
- Sanitary - cutting off the leaves and pruning of winter-dying parts of the plant.
- Pruning to form the crown of the bush.
- evaporation of moisture from the leaves, which depletes the plants and increases the humidity inside the shelter;
- their rotting on a bush in a shelter and infecting with the rot of the whole plant.
Did you know? Wild rose flowers have 5 petals. A large number of petals of cultivated species is the result of a successful mutation.
Formative pruning is carried out depending on the variety and is divided into 3 types:
- Short pruning - leave shoots with a pair of buds. Perform this type of pruning infrequently. Cascade shtambovye species are shortly cut only in the first year, the length of the shoots after such pruning is 15-18 cm.
- Medium - 35–40 cm, 5–6 buds are left; they are performed on hybrid tea, polyanthus and floribunda roses, grandiflora, and remontant varieties.
- Long pruning - leave no less than 10 buds, slightly shortening the shoot. Apply to old English, shrubby and climbing roses.
We recommend to get acquainted with the peculiarities of growing Canadian roses and roses of the variety “Double Delight”.
Shoots climbing roses cut to 30% of the length, except for small-colored species, which pinch the growth point. Climbing varieties bloom on last year's shoots, because of this they can not be too pruned. Only old perennial shoots are shortened to 30 cm, to stimulate the growth of young stems.
Important! Ground cover and park species of roses require only sanitary pruning.
Weak, not mature and sick shoots are completely cut off.
3-5 mature escapes are left trying to observe symmetry and such principles:
- Pruning is carried out in dry and clear weather.
- For thicker stems, use a hacksaw to prevent the wood from cracking.
- Sections are performed at an angle for dripping moisture.
- The cut core must be white.
- The cut is made above the swollen buds 5 mm higher, so that the shoots growing from them do not intersect in the future.
- After finishing pruning, remove all the leaves, carefully walking along the stem from the bottom up with a hand in a thick glove.
How to cover roses
To create an air-dry shelter of roses for the winter you need:
- frame;
- covering material.
- Plastic film - it is durable, but you need to leave the ventilation holes, as under it the roses can melt.
- Sacking, thick rags, old jackets and coats - these improvised materials are cheap, but not very convenient.
- Agrofibres, spanbond, lutrasil - this is a special synthetic material, well pass moisture and air, you can buy any required footage, will last several seasons, are convenient to use.
Did you know? The world's largest rose bush grows in Arizona, USA, occupies an area equal to a football field, and about 200 thousand buds bloom on it once a year.
Also, roses for the winter are wrapped with burlap or heavy paper and harbor without frame:
- dry leaves;
- lapnik;
- sawdust.
This method is suitable for low bushes and cold-resistant varieties.
Use air-dry shelter to preserve
In the shelter of roses exposed to 2 hazards:
- Rodents - for prevention in the tunnels are spreading the poison from rodents.
- Vypleivanie - without access to air and at high humidity shoots choking and they are affected by pathogens.
For this reason, roses are covered directly, having sustained them for 2 weeks at an air temperature of less than 2-5 ° C below 0. This also will not allow rodents to start in shelters.
The stems of roses gently bend down to the ground and laid on the material spread below. If necessary, the stems pin to the ground with metal brackets. The base of the stem should be well spud.
Important! If the shoots cannot be laid on the ground, for example, in shtambovyh varieties, the frame is erected vertically.
A covering material is laid over the frame. Agrofibre, spanbond, lutrasil folded in 2-3 layers. Applying polyethylene, leave holes for air. The material is pressed to the ground with boards and bricks.
If dry snow falls, you can pour it over the cover for additional insulation.
