Where to plant spirea

Despite the fact that spireas are divided into those that bloom in early spring and those that bloom in summer, the requirements for lighting, soil fertility, and moisture are approximately the same.

Most types of spirea are very demanding on sunlight. Only a few of them are able to grow equally well in the sun and in partial shade. Grows well in light shade of birch spirea. However, planting a spirea in very dark places threatens the plant with slow growth and loss of decorativeness. This is especially true of varieties and hybrids with variegated and colored foliage.

Spirea is sensitive to soil fertility. It grows well on light, permeable lands with a high content of leafy or soddy soil. The acidity of the soil can be both slightly acidic and slightly alkaline, and neutral.

Temperature regime

The plant feels great in rather harsh climatic conditions and tolerates frosts up to -35. Sometimes frost damage to the tops of the shoots is observed, but given the fact that in many species the shoots of the current year bloom, the frozen parts can be cut off.

The plant has good drought tolerance. Needs additional watering in hot summer and in the first year after planting. Excess and stagnation of moisture is not desirable. Spirea will grow very badly in swampy areas. After choosing a suitable site, you can start planting the spirea on the site.

How and when to plant a spirea

Planting material

All spireas can be propagated by seeds and vegetative parts. With seed reproduction, there are two drawbacks - late flowering, not earlier than after 3 - 4 years. The second disadvantage is the formation of seeds in hybrid forms that do not convey the qualities of the parents. The result of such cultivation is unpredictable. If a seed propagation method is chosen, then at the end of winter or early spring, the seeds are sown in seedling boxes.

The soil can be taken universal. Make grooves and sow spirea seeds. Moisten everything and cover with glass. Seedlings will appear in a week. When the seedlings get stronger, they can be planted in open ground. Sometimes, during seed reproduction, spireas grow very slowly. If they have not reached a size of 10 - 12 cm by June, then they will have to be planted in open ground only next spring.

Planting methods

Therefore, the seed method is best used to obtain rare and beautiful varieties, if there is no way to get other planting material. The cuttings are rooted in moist soil, and transplanted to a permanent place only for the next summer. It is more convenient for planting to take root suckers or seedlings obtained from the rooting of the tops of the shoots.

You can also use the material obtained by dividing the bush. Such spireas will begin to bloom next year. Spirea seedlings with open roots or an earthen clod can be planted in spring and autumn. In spring, the best time will be the end of May, and in autumn, mid-September.

Seedlings in containers can be planted at any time. The depth of the hole should correspond to the length of the roots, and the width should not be less than one and a half or two times wider than the root system. The distance between the pits depends on the variety and purpose of the planting. But you should not place them closer than 0.5 - 0.7 m. For tall varieties with wide bushes, the distance should be at least 1.0 - 1.2 m. For drainage, broken brick is laid on the bottom of the pit and covered with sand.

Planting a seedling and care after planting

The spirea seedling is set so that the root collar is above the ground. If the root system is open, then it is advisable to keep the seedling for 12-18 hours in a growth stimulator before planting. An earthen lump is not removed from the roots. Open roots are spread over the ground. Gently cover the roots with earth, slightly compacting it.

Immediately after planting, the plant is watered with a bucket of water. The trunk circle must be covered with a layer of peat. Layer thickness - 7 cm. In dry weather, watering should be repeated every 3 - 5 days. It is also necessary to regularly loosen the ground between the spirea bushes. As the seedlings grow, they will need feeding and pruning.

How to care for an adult spirea

An important point in caring for spireas is pruning. Conventionally, all spireas can be divided into those that form flowers on the shoots of the current year and those that give flowers on last year's shoots. In the first case, the bush is cut in the spring, while cutting off the dry inflorescences of the last year. In the second case - in summer or autumn, after the end of flowering.

In addition, the bushes need to be rejuvenated. To do this, annually cut out old shoots that are older than 7 - 8 years old. Sometimes in summer spirits, you can shorten the shoots up to 0.3 m above the ground every four years in the spring. After such pruning, the bushes grow even more luxuriant. Equally important is the preparation of spirits for winter. Despite the frost resistance, the roots of many varieties and hybrids can freeze out.

To prevent this from happening, plant debris is removed from under the bush and mulched with a layer of peat of at least 10 cm.The following types of spirea can be recommended for cultivation:

  • Japanese
  • Boomald
  • Douglas
  • nippon
  • grayish

Care for all spireas is about the same, it remains to choose the type and variety to your taste.
