Spirea is a beautiful shrub that has become widespread in the last 10-15 years with our gardeners due to its decorative qualities and variety of species. Most of them have a very remarkable flowering: fluffy umbrellas or panicles. Color - from white to bright pink.
Spirey Billard: distinctive features
It is very interesting that all types of spirays belong to the Rosaceae family, which includes a lot of diverse cultures, which differ in appearance and application. The leaves of different types of spirea are different. They may be ovoid, as in oak-leaved spirea, or oval in shape, as in Japanese.
Spirea Billard - the result of the crossing of the spirea Douglas and willow. Its distinguishing features are:
- Plant height is approximately 2 meters. Some specimens can reach 2.5 meters.
- Winter hardiness is high. It withstands freezing to minus 30-35 ° C without shelter.
- The branches are erect, the shape of the bush is rounded.
- The leaf plate is similar to the leaf of an icy-leaved spirea, the form is lanceolate with small teeth at the edges. The color of the sheet plate above and below is slightly different in saturation. Below it is grayish. With the arrival of autumn, the color of the leaves changes to brown and reddish.
- Bloom. Dark pink panicles resemble Douglas Spirea inflorescences. Only Billard, they are a bit larger, up to 20 cm in length. This species blooms late, starting in July. Flowering can last until the first frost.
In general, the plant has a large size and is quite suitable for creating hedges. A bush without flowers is very beautiful in itself: powerful shoots look up and sideways. Despite the rounded flat shape, the bush does not fall apart. It blooms when other types of culture are already fading. Large bright inflorescences add beauty.
Saplings of Spirea Billard planted in a new place in the spring, when the snow melts. The pit for her is better to prepare in advance in the fall. If you plant several copies at once, for example, as a hedge, you can dig a trench in advance. Pit size: width, length and depth - 40-50 cm. The trench is digging depth and 40 cm wide.
There is a general rule for planting any perennial crops, especially trees or shrubs. If you plant them in the fall, then you need to dig a hole in spring or summer a few months before planting. If landing is to be in the spring, then the landing hole is dug in the fall. This is done not only to the soil settled.
The pit is immediately filled with humus, compost, superphosphate is added (at the rate of 2 tablespoons per mixture bucket), and ash. Stir and leave. This fertile mixture should “mature” properly, be filled with oxygen, its own microflora should form there, the soil should “come to life”.
In spring we plant spiraeus as follows:
- digging a pit deep with the root system and watering well,
- we put a seedling and pour the prepared earth from the sides,
- squeeze her hands and water again,
- if the roots are exposed, then again pour a little loose earth.
The soil around the seedlings can be mulched. These can be sawdust, tree bark, leaves, cut grass (without flowers), or rotted compost. It is not recommended to water the planted spiraeus for about 2 weeks. In these conditions, the root system will develop better.
Shrub planted in a sunny place, although it can grow in partial shade.
In group plantings with other plants take into account that the branches of the bush can grow to the sides of more than a meter. And in accordance with this plan landing.
How to care for culture
Spirea is not considered a capricious culture. There are many types of spireas, some of them are loved by our gardeners. But despite their diversity, all are distinguished by one valuable quality - unpretentiousness. There are general rules that must be followed to make Billard's bush delight you with its lush and long flowering. Here they are:
- Spirea needs constant watering. She does not like drought, her stems immediately become bare, the leaves become smaller and dry. Inflorescences with insufficient watering are not so thick and bright. Transfusion also should not be allowed.
- After planting, you need to endure 1-2 months without supplements. And after, like other ornamental plants, the culture must be fertilized. In the first year, when the above-ground part is actively growing, it is possible to feed with “green” fertilizer, extract of mullein and bird droppings. That is, for the first time, we actively “feed” the plant with nitrogen. The regularity of such feedings - 1 time per month. The following years we feed up the spiraeus with a complex mineral fertilizer.
- To preserve moisture in the soil, the surface around the bush can be mulched.
- One of the ways to care - pruning. If the spiraea is not cut for a long time, then it stops blooming, then you have to do a cardinal pruning. It is best to remove dying shoots, dried and weak, each year.
Spiraeus Billard can not cover for the winter. If the winter is to be frosty, then you can tie up the branches and bend them. But based on the experience of gardeners, this type of spirea happily overwinters without various manipulations.

Spiraea multiplies in hay and vegetative ways. The first method is rarely used because it is too long and more suitable for breeders. Vegetative method includes:
- reproduction by cuttings,
- division of the bush.
Spirea cuttings are harvested during flowering. Choose non-flowering shoots and cut branches into pieces. Each stalk should have 4-5 buds. They are planted in wet ground: it can be soil near a bush or a flower pot. The main condition is constant humidity. At a permanent place sapling planted next year.
One of the most common methods of reproduction is by layering. The branch of the spirea is tilted to the ground, a part is buried by 5 cm and sprinkled with earth. To rooting better, a part of the branch that will be in the ground can be slightly removed from the bark. This will improve the formation of roots. To keep the branch from rising, it is pressed with a stone or pinned.
The division of the bush produced in early spring or autumn after flowering. The bush is chopped on top with a sharp shovel. The separated part is dried for 2-3 hours in the shade, the cut is sprinkled with crushed coal to prevent flowering. Put in the moistened soil.
Each method has its pros and cons. When propagating by cuttings, the bush does not lose its decorative effect. When you propagate by layering, a new plant receives constant nourishment from the mother bush, which is very important. The division is suitable for those who want to immediately get a big lush plant.
Other popular varieties of spirea
Spireas are very diverse both in height and in the form of a bush, leaves and flowers. We list the most famous of them.

Application in landscape design
Spirea quickly found application in landscape design due to its unpretentiousness. It is rare to find such a combination of beauty and frost resistance. Sometimes it is possible to observe how flowers that have fallen ill or have not withstood the cold weather change in a flower garden. And spiraea bushes grow at the same time as if nothing had happened.
The inflorescences of such plants grow on the tops of young shoots. Old shoots left over from that year dry out over time. The varieties of Japanese spireas represent most of the summer flowering. Most often, flowers have a pink color, but can be pinkish-red or red. The most popular types are:
Features of growing
Any plant has any peculiarities in the care of it and spiraea is no exception:
- Best of all, such a plant develops and grows on sod or leaf ground. Recommended composition of earthworms: soil, sand and peat (2: 1: 1).
- At the bottom of the fossa it is necessary to make a layer for drainage, for example, from broken brick.
- The pit for planting should be 1/3 part larger than the size of the spiraea.
- Plant need to a depth of not less than 50 centimeters, while ensuring that the root neck was on the same level with the surface of the soil.
- Planting this plant is recommended to engage in a cloudy day, and best of all during the rain. The optimal time for disembarking is September.
- The fir-tree, juniper and thuja are feeling fine next to the meadowsweet.
