Description and characteristics
Stock rose (mallow) is a tall plant with long erect stems. The bush reaches 160-180 cm. The shoots are dense and strong, covered with light green soft bark.
There are no leaves on the top of the plant. Only basal plates are present, the diameter of which reaches 12 cm. The leaves are palmate in shape, dark green in color.
Bushes have taproots. Thanks to this structure, underground shoots grow deep into the ground. This has a positive effect on the resistance of mallow to adverse weather conditions.
Stock-rose begins to bloom in the second year after planting in the ground
The budding period takes place in early June. On the upper part of the stems, flower stalks are formed with small light green leaves. Mallows bloom in July. During this period, flowers with a diameter of 6-8 cm appear on a wrinkled stock-rose. They gather in panicles.
Stock rose is considered an undemanding crop. It grows well in almost any type of soil. Wrinkled mallows do not tolerate a lack of fluid. Prolonged lack of watering shortens the flowering period, can lead to drying out.
Stock-roses are characterized by medium frost resistance. Bushes of wrinkled mallow hibernate in the ground, but this requires shelter. A sharp drop in temperature to -10 degrees can greatly harm young bushes.
The plant is resistant to many types of diseases. Wrinkled stock roses are immune to powdery mildew, root rot and most other infections. In the summer, pests can start on the mallows.

Planting and caring for wrinkled rose
To grow a bush in an open area, you must follow a few rules. First of all, competent planting is required. It can be complicated by the fact that mallows are grown from seeds.
Terms of planting
Usually the plant is immediately planted in open ground. Landing is carried out at the end of April or in May, when the soil warms up, and the air temperature will always be at least 8 degrees.
When growing in this way, it must be taken into account that the germination rate is very high. Almost all seeds germinate, but due to unfavorable conditions, seedlings may wither prematurely.
Site and soil requirements
Mallows grow well in any type of soil. But in order for wrinkled stock roses to last in the soil as long as possible, it is recommended to choose a place that meets several requirements.
Among them:
- looseness and air permeability of the soil;
- availability of nutrient sources;
- moderate humidity and acidity;
- low groundwater level.
For planting, you can use standard soil for flowering plants. Mix compost, garden soil, sand and peat in equal proportions.
Growing requires a well-lit area. It must be protected from strong winds.
Landing and aftercare
The area must be cleared of weeds. It is advisable to dig and loosen the soil. Seeds are pre-soaked in a weak fungicidal solution to prevent infection.
Landing steps:
- Make holes in the prepared area.
- Place a small amount of humus or compost.
- Pour in some water.
- Place the seeds without digging into the soil.
- Sprinkle with loose soil in a layer of 2-3 cm.
Seeds are sown in furrows or individual pits.
Wrinkled stock roses are unpretentious, therefore they do not need specific care. It is enough to water the bush periodically so that it does not experience a lack of liquid. Around the wrinkled mallow, weeds must be removed in a timely manner.
In summer, as the soil compacts, loosening is required. To preserve moisture, the soil is mulched with bark, peat or sawdust.
Tall varieties of stock roses require a garter. Otherwise, the shoots may break due to a strong gust of wind.
Wrinkled mallows do not need mineral supplements. It is enough to apply organic fertilizers 2-3 times a year.
Best fit:
- compost;
- litter or manure diluted in water;
- peat;
- wood ash.
For the winter, the plant is pruned, leaving short (8-10 cm), surface shoots. They are wrapped with a breathable film or covered with dry foliage and spruce branches.
pruning wrinkled rose
Mallow haircut is carried out 2-3 times a year. For the first time, a wrinkled stem-rose is cut in the spring, during the period of active shoot growth. Remove excess stems, as well as collateral root shoots.
In summer or early September, fading flower stalks are cut off. This is necessary in order for the mallow to prepare for winter. In addition, wrinkled stock-roses are able to propagate by self-sowing.
Pruning of peduncles must be carried out before the formation of seed boxes
In autumn, all surface shoots are removed. Sections are recommended to be treated with an antiseptic solution to prevent decay.
Reproduction of a wrinkled rose
To get new specimens of mallow for planting in the garden, you can use one of the proposed methods. Wrinkled stock roses tolerate almost all methods of reproduction well.
Mallow cuttings
Young lateral shoots growing on the main stems are used as planting material. They are harvested in the spring, after which they are rooted in a nutrient substrate. It is recommended to transplant cuttings into open ground in the fall. Then they will better adapt to new conditions and will be able to endure the first winter without damage.
Reproduction by seeds
The collection of planting material is carried out in September. Seeds are stored in a cool place with moderate humidity. In March, they are soaked in a growth stimulator and sown in a container with nutrient soil.
Shoots appear after 2-3 weeks. They need to be watered regularly. Picking is carried out when the first true leaves appear.
Seedling growing technology:
