What does Crisp's spirea look like, especially planting and care
A Japanese shrub called Crispa's spiraea (in Latin - Spiraea japonica Crispa) is considered one of the best plants for creating hedges. He often lands in large flowerpots or containers to decorate the entrance to the house, on the balcony or terrace. At the same time, the shrub does not require special care and tolerates long-term frosts.
Japan is considered the first country in which this variety appeared. The plant is a deciduous shrub with a dense crown of spherical shape. Each leaf is sharp-toothed, but not sharp. At its top there is a small curl inside, which gives the plant an openwork look.
The description reports that in the spring the spirea acquires a special color: the main green foliage alternates with young shoots that have a burgundy hue.
In the summer, the shrub begins to bloom with purple-pink flowers, the last petals of which fall only with the onset of the first frost. All these features became the reason for the active use of plants in landscape design.
Shrub planting and care
According to gardening experts, anyone can cope with the planting of spirea with a minimum of effort. Ideal time for planting in open ground are considered autumn and spring.
Did you know? In the X-VIII century BC in Greece, the first attempts were made to equip gardens and parks. It is from this period that the most famous Greek style in landscape design originates.b.
How and when to plant
As stated above, shrubs can be planted at any time except winter. Optimal is the choice of a day that is not sunny. Planting in cloudy and slightly rainy weather contributes to better plant survival at the selected location.
Before direct planting in a prepared depression in the ground, the seedling is abundantly filled with water. This process must be done if the plant was sold in the ground. A large amount of liquid will soften the soil and the roots of the bush will not suffer when removed from the container.
When planting in the ground, it is not necessary to clear the root system of the soil - a significant lump of earth should remain on it. Those roots that remain open are straightened. So much new soil is added to the recess so that the root neck is on par with the total mass of the earth.
Immediately the first pruning of the seedling occurs to a third of its total size. After this, abundant water is carried out. Immediately mulch the soil. Peat is ideal for this.
Like any plant, Crisp's spiraea requires a certain amount of fertilizer.
They are divided into two main groups:
Mineral fertilizers should be purchased exclusively in specialized stores. The best option is to purchase a complex mixture. Its composition may vary depending on the soil in which the shrub has been planted, so in each case it is necessary to consult with the seller.
Be sure to include phosphorus, nitrogen and potassium.
Organic fertilizers can be of plant or animal origin. As the first option, any humus that usually accumulates in silos in summer cottages is suitable.
Organics of animal origin, or manure, can be purchased at a specialized store or ask those involved in livestock breeding.
It is very important in the first and second case to observe the dosage, which in each case will be different.To determine it, it is better to consult the label of mineral fertilizers or consult a specialist.
Watering and feeding
Japanese Spirea Crispa, as mentioned above, is an unpretentious plant. A distinctive feature is that it does not require additional watering, except for rainfall. If the summer turned out to be too dry, then it is allowed to pour 1 bucket per day under the bush.
Important! Spirea Crispa does not like a lot of water at her roots. In this regard, it is forbidden to plant shrubs near wetlands, at places of accumulation of underground or melt water.
Abundant fertilization of the plant is also not needed if it is planted in fertile soil. If in the soil there are not enough minerals, they can be purchased and additionally nourish the bush. They are brought into the trunk circle.
In this case, the period of the year should be taken into account, namely:
- In summer, any complex mineral fertilizer with a high content of potassium and phosphorus is introduced. This procedure will allow the spirae to bloom profusely.
- In spring, it is better to focus on fertilizer that contains the maximum amount of nitrogen. The most common option is nitrofoska.
- In autumn, when the time for preparing for winter approaches, it is necessary to feed each bush with superphosphate.
Some gardeners and masters of landscape design recommend caring for the bush with the help of complex mixtures. They can feed the plant only once - in the spring.
The most popular and well-known version of such fertilizers is Kemira Universal.
The bushes of the plant tolerate pruning without any complications. Used in landscaping, Crisp's spiraea needs constant sanitation. During this period, dried or damaged branches and inflorescences are removed from her. If you remove the faded inflorescences in a timely manner (until the fruit is formed), you can significantly extend the flowering period of the shrub.
In addition to this procedure, there are several more cropping techniques, namely:
The first mechanical removal of shoots is carried out after the first three years from the moment of planting a bush. Stimulating pruning is done to seal the crown. Usually it is carried out in the autumn period; only those shoots that are located 25 cm above the ground level and have a stiff look are removed.
A similar technique will allow the bush to bloom in July, otherwise flowering begins in June. Stimulating pruning avoids re-blooming in September and reduces the likelihood of seed formation.
Did you know? Topiary (from the English topiary) - a special kind of horticultural art, the creation of "living sculptures" from plants by curly haircuts.
Forming pruning is carried out in order to refine the bush, giving it a special geometric shape. Landscaping often uses the right hemisphere. This technique is applied throughout the entire growth of the plant and is carried out almost every month: shoots that go beyond the limits of the form are cut off.
If Crisp's spirea bush is old, then he may need a rejuvenating pruning technique. To execute it, it is enough to cut the entire bush at ground level. This will contribute to the development of young kidneys that remain near the root. Such pruning is very useful, as it allows you to grow a completely new bush on the old root system.

How does reproduction occur?
Like many shrubs, the propagation of Crisp's spirea is carried out by two main methods - seed and vegetative. For the first option, you will need to collect fruits from the bush that will fully ripen after 2 months after flowering.
The seeds obtained are subjected to the process of stratification, and then incubated for some time at minus temperatures. During this period, the seeds are placed in a special container.You can store it both in the refrigerator and in the snow, after digging it in advance.
In early spring, seeds are planted in the ground. The crop area is covered with a film. After 3 months, the young shoots are transferred to the greenhouse. A significant drawback of the seed method is that it does not guarantee that a varietal plant will be obtained from the material.
In this regard, spirea is often subjected to a vegetative method of reproduction, which in turn is divided into several species, namely:
- division of the bush;
- layering from the mother bush.
The technique of cuttings is considered one of the surest ways to preserve varietal traits in a plant. The cut is created from the shoot, on which 5 leaves are left. At the same time, the three lower ones are completely removed, and the upper two are cut in such a way as to leave only half of them. Planting material created in this way is immersed in the Epina solution with the lower cut to the bottom of the vessel.
After this time, a powder treatment called “Kornevin” is carried out. The next step will be the planting of the cuttings in the prepared wet sand in a pot or container. It is enough to deepen them by 2 cm at an angle of 45 °. It remains only to cover the material with glass or to wrap it with film and put it in a warm place.
At regular intervals (about once every 2-3 days), the stalk is opened, sprayed with water and moisten the sand. The first roots appear after 2 months. In the future, they are stopped and planted in separate flowerpots.
The method of dividing the bush is considered the least simple, but at the same time time-consuming. It is carried out in September. To do this, you need to completely dig out a five-year-old plant, and rinse the roots under running water from the ground. Using a secateurs, the root is trimmed and divided into 2-3 parts.
At the same time, the essence of the process is that on each separate part there are young shoots, a stem and fibrous root system. It remains only to land the divided spirea in pre-prepared pits in the usual way.
Layering is created by bending one of the shoots of the mother bush to the ground and fixing it in this position for a while. The branch is pre-sprinkled with earth. With frequent watering of this site, the branch will take root and form its own shoots.
In this position, she is left for the whole winter. In early spring, when the first warm days begin, the cuttings are cut off from the bush. At the same time, it is dug up with roots and transferred to a new place.
As indicated at the beginning of the article, the Japanese spiraea Crispa tolerates wintering perfectly. In the middle zone of the country, it can be completely not prepared for the cold season. If nevertheless there is a desire to protect the plant as much as possible, basal mulching with a thick layer of peat is carried out. Instead, it is allowed to use sawdust or bark. In this state, the bush is dug in from above with snow.
Diseases and Pests
Plant diseases rarely infect Crisp's spirea. Old bushes that have not been trimmed for a long time are most at risk. Lack of care provokes a strong thickening of the crown, inside of which an excessive amount of moisture accumulates.
In this situation, fungi multiply rapidly, especially in rainy and cold summers. The only way to combat is the removal of affected shoots and their burning. You can stop the further growth of the fungus by spraying the bush with a fungicide. One of the most popular drugs is copper sulfate.
Important! If pests or diseases are detected, fallen leaves in the autumn are completely removed from the surface of the earth and burned. They may contain larvae or spores of the fungus.
Among pests that cause harm to spirae, emit aphids, spider mite and leaflet. The method of control is reduced to spraying the shrub with any insecticide or acaricide sold in specialized stores.In this case, you should choose only the substance that fights with a particular pest.
In the early stages of infection, it is enough to remove the shoots with insects.
Spirea Crisp in landscape design
The use of Crisp's spiraea bushes in landscape design is due to the fact that the plant has a specific spherical shape and blooms for a long period of time. In this case, the shrub remains small. Landing is carried out both in single and in group plantings.
Due to the attractive color of the flowers, the bush can become a central element in the composition on the flowerbed. Planted in a flowerpot or a small container, it will perfectly decorate the entrance to the house, on the terrace or on the balcony. In a group planting, spirea is used in several variations.
The height of the bushes allows them to become one of the layers of a multi-level living fence. They are also often used as decoration for paths in the garden or alleys, creating an unusual landscape. Known options for planting in mixed landings and mixboards.
Based on the above facts, it is safe to say that the Japanese spirea Crispa is unpretentious, beautiful and easy to care for. With its help, they decorate not only gardens, but also personal territories. Simple care and high resistance to cold make planting a bush justified. A long flowering period and beautiful shape will help to remember the created landscape design for a long time.
