Spirea Shiroban is an ornamental shrub of the Rosaceae family, which is very popular in Russia. This is due to the endurance of the variety, the low price of planting material and the beauty of the plant. In addition, Shiroban's spirea is highly valued for its resistance to low temperatures and unpretentiousness.

Description of Spirea Shiroban

Japanese spirea Genpei Shirobana is a small plant, about 70-80 cm high. The bush is highly branched and grows rapidly in width - the diameter of the bush can reach 120 cm. Young branches of the spirea are pubescent. The color of the shoots is reddish brown.

The shape of the leaves is ovoid, slightly elongated. They are small in size. The outer part of the leaf plate is colored dark green, but below the leaves are gray. In the fall, green tones turn into orange or even reddish shades, making the spirea bush look beautiful even after flowering.

The color of the flowers of the Shiroban spirea varies from white to pale pink shades. This variety blooms throughout the summer.

Spirea Shiroban in landscape design

The Japanese spirea of the Jenpei Shirobana variety in landscape design is used to form a uniform hedge, curbs and decorate slopes. The shrub is also planted with other varieties to create spectacular group compositions. Due to the fact that different varieties bloom at different times, the decorativeness of such flower beds stretches for the whole season.

Advice! The trunk circle is decorated by planting a saxifrage, multi-colored lungwort or periwinkle next to the spirea bushes, which grow like a carpet, completely covering the ground.

Planting and care of the Japanese Shirobana spirea

Planting the Shiroban spirea, as well as the subsequent care of the plant, as a rule, does not cause much difficulty. What you should pay attention to before planting a shrub:

Spirea Shirobana prefers open sunny areas, but grows well in partial shade.
There are no special requirements for the composition of the soil, but it is better to plant spirea on loose light soils.
The recommended planting time for the Shirobana variety is early September.
It will be easier for seedlings to adapt to a new place if planting is carried out in rainy, cloudy weather.

This garden culture is unpretentious and it will not do much harm if these recommendations are not followed, however, the listed conditions are necessary for the most abundant flowering of the bush.

Advice! The neighborhood of the Shiroban variety next to conifers has proven itself well: spruce, juniper, thuja.

Preparation of planting material and site

Preparing a site for planting a Shiroban spirea is reduced to digging a place and applying organic fertilizers to the soil. As for the planting material, it does not need any special preparatory procedures. It is enough to inspect the seedlings and reject specimens with significant damage: cuts, breaks of shoots and ruptures of roots.

Important! The roots of the seedling should not be too dry. If they are overdried, the planting material is dipped for a while in a container with water.

Planting Spirea Shiroban

The planting algorithm of the Shirobana variety is as follows:

Pits are dug on the site, the diameter of which should be slightly larger than the root area of the seedlings. The depth of the holes should not exceed half a meter.
I put drainage on the bottom of the pits: pebbles, gravel, broken brick or clay shards.
The drainage layer is sprinkled with a mixture of peat, sand and garden soil, taken in equal proportions. A thin layer of soil must be poured over this soil mixture so that the roots of the spirea do not touch the peat directly.
The seedlings are lowered into the holes, the roots are evenly distributed along the bottom and covered with earth. The root collar should be level with the ground or slightly higher; it cannot be buried.
Planting is watered and mulched. Mulch promotes better moisture retention in the trunk circle. Peat or walnut shells are best suited as mulch.

Advice! You can add 1 tbsp to the soil mixture. l. complex mineral fertilizer. This will provide the Shiroban spirea with nutrition for 1-2 years, as a result of which the absence of subsequent fertilizing will practically not affect the development of the plant.

Watering and feeding

Spirea Shiroban needs more careful care in the first year of life, which includes frequent watering. The soil near the bush should not dry out. Adult plants are watered at least 2 times a month. At the same time, about 10-15 liters of water are consumed for each bush.

Important! After heavy rains, a dense crust can form on the surface of the earth. This entails oxygen starvation of the bush, therefore, it is recommended to loosen the spirea's trunk circle from time to time.

The bushes are usually fed in spring. Complex fertilizers are applied to the soil according to the instructions. Young seedlings can be fed in the summer with a mullein solution with the addition of

Pruning

Sanitary pruning of last year's shoots is carried out in early spring. In this case, it is important to be in time before the buds bloom. Weak shoots can be removed completely. The procedure promotes more active growth of young growth.

In the 4th year of life, you can carry out an intensive rejuvenating pruning of the Shiroban spirea. For this, the branches are cut so that only stumps about 30 cm long remain. Starting from the age of 4, such pruning can be carried out annually.

Important! If the old branches are not pruned, over time they begin to lean towards the ground, which leads to the fact that the spirea seems to fall apart, losing its attractiveness.

After each pruning, the planting is abundantly watered and fertilized. To do this, you can use a solution of manure or superphosphate. Recommended proportions: 10 g per 10 liters of water. Fertilizer is applied to the very root of the spirea.

Preparing for winter

Spirea Shiroban is capable of wintering without harming development without covering material, but this applies only to adult plants. Young seedlings are too weak to survive the winter under natural shelter - snow. It is recommended to sprinkle them with a thick layer of dry leaves.

Reproduction

Spirea Shiroban can be propagated in the following ways:

cuttings;
layering;
dividing the bush;
seeds.

The latter method is used very rarely, since during seed reproduction, the varietal qualities of the garden culture are often lost.

The most popular is the grafting of spirea. The advantage of this method is the high survival rate of the planting material, even without processing the cuttings with growth stimulants.

By cuttings, Shiroban's spirea is bred as follows:

The shrub is examined and an annual shoot is selected on it.
It is cut almost to the root and the resulting cut is divided again into several parts. The length of the cutting should be on average 15 cm. Each part should have no more than 6 leaves.
The bottom of the cuttings must be cleared of foliage.
The remaining leaves are cut in half.
Cuttings are dipped for 5 hours in a solution of the drug "Epin" (1 ml per 2 liters of water).
After this time, the lower cut of the cuttings is sprinkled with a growth stimulator (you can use "Kornevin"), after which the planting material is planted in containers filled with sand.
The cuttings are deepened at an angle of 45 °.
Then the cuttings are covered with jars or foil, after which the containers are removed in the shade.
With the onset of the first cold weather, the boxes are dropped into the ground and covered with dry leaves.
In the spring, the boxes are opened and the spirea is transplanted to a permanent place.

No less popular is the cultivation of Shiroban's spirea by layering. Layers are formed according to the following scheme:

One of the branches of the spirea is gently bent to the ground, trying not to break it.
The end of the shoot is buried in the ground and fixed with a metal bracket or a heavy object.
When the cuttings form a full-fledged root system, it can be separated from the mother bush and planted in another place.

Another vegetative way of reproduction of the Shiroban spirea, in which all varietal qualities are preserved, is the division of the bush. The procedure is carried out as follows:

In the spring, before the buds bloom, the bush is dug up together with an earthen lump.
Spirea roots are dipped into a basin of water. This is necessary in order for the earth to soften. This makes it easier to clean the root system of the plant.
The rhizome is divided into 3-4 equal parts, after which each part can be seated.

Important! The only drawback of this method is the high risk of infection of the bush. This happens if you divide the bush with blunt tools. The problem is solved by soaking the roots of the resulting seedlings in a fungicide solution.

Diseases and pests

Spirea Shiroban rarely suffers, but plantings can infect pests. The most dangerous for this variety include the following insects:

aphid;
spider mite;
rose leaf roll.

The fact that the tick was struck by the spirea is evidenced by the formation of a thin web on the leaves. In addition, the shrub begins to turn yellow ahead of time. He drops the leaves shortly thereafter.

The danger of a spider mite is that it depletes the bush very quickly. It is impossible to drag out the fight against him. Any insecticide effectively copes with the pest, but the preparations "Phosphamide" and "Karbofos" have proven themselves especially well. The dosage is indicated in the instructions.

Aphids annoy gardeners in the second half of summer. The presence of the pest is determined by the eaten inflorescences, from which the insect sucks out the juice. Leaves also suffer, on which small holes appear. You can get rid of aphids with the help of the Pirimor insecticide, a solution of grated laundry soap or ash.

Reviews of Shiroban's spire

Kochetkova Valentina Petrovna, 50 years old, Dankov

Pros of the variety: unpretentious, very beautiful, tolerates severe frosts well. Disadvantages: did not notice. I bought Shiroban's spirea 4 years ago, I'm very happy. I don't really like to mess with flowers, but I wanted to decorate the site, so the variety is just for people like me, lazy. The bush grows quickly, blooms well, almost all summer. Spirea hibernates with me without shelter, I grow it in a small shade. For all the time, the bushes have never got sick, although I do not even process them. I don’t bother with top dressing either. Is that, in the planting hole poured fertilizer, and that's it. So, all care comes down to watering. In the spring, I sometimes remove dry branches. Once every 1-2 years, I cut out old branches. The bushes are neat, beautiful. In general, I recommend it to everyone.

Belousova Natalia Alexandrovna, 45 years old, Moscow.

In general, I never considered myself an avid gardener, but somehow I saw a photo of a spirea long ago, found out that it was a Shiroban variety and climbed to read the description. Fortunately for me, it turned out that caring for the bush is very simple, which is important for me - I don't want to spend a lot of time on the garden, I just want to relax at the dacha in a beautiful environment. What can I say, so far everything suits me. I planted a spirea next to the thuja, it turned out to be a good composition. Already 5 years have passed, there were no problems with diseases. Once the aphid gnawed at the leaves, but after treatment with soapy water it was possible to get rid of it. Spirea Shiroban blooms very beautifully and for a long time, all summer. The plantings hibernate well, I covered the seedlings only in the first year. Then snow copes well with insulation. I hardly even water spirea, there is enough rain in our area. Unpretentious, hardy shrub. I do pruning to a minimum, just to give the bush a beautiful look.

Conclusion

Spirea Shiroban is ideal for those who do not have the opportunity or desire to spend a lot of time caring for the garden plot. This variety does not require special attention to itself, so even a beginner can cope with the cultivation of a shrub. The frost resistance of Shiroban's spirea allows it to be grown in almost all regions of Russia.
