Lacy greenery with bright panicles of flowers is found in all climatic zones of Our Country. Its endurance and ease of care attract flower growers. To achieve its lush flowering, you need to know how to properly transplant astilba to a new place.
The bright color of astilba varieties allows you to make interesting combinations in the landscape.
Why do you need to transplant astilbe
The astilbe bush grows and blooms without transplanting for decades. For a long growing season, the rhizome rises above the ground. There is a threat of its burning out in the summer, rotting from increased moisture, frostbite without snow cover.
Over time, the structure of the soil is depleted and changes – the roots suffer from oxygen and mineral starvation. Without a transplant, the inflorescences become smaller, their number decreases. Greenery loses volume and attractiveness.
The root system of the bush increases by an average of 4-5 cm per year, which makes it difficult for astilba to grow in dense group plantings. The flower is recommended to be transplanted after 3-4 years.
When can you transplant astilba
The perennial is transferred around the site throughout the growing season. This does not always happen without loss. Favorable terms depend on the climatic conditions of the region. You can transplant astilba to another place:
- in early spring, when the growth buds swell;
- in the summer, however, experienced gardeners advise waiting until at least 6 buds are released with a flower, observing the transplant rule – do not disturb the earthen clod;
- in the fall – after the astilba has completely faded.
A plant transplanted during these periods adapts faster.
When is the best time to transplant astilba: in spring or autumn
Timing depends on the purpose of the process. Astilba transplantation for rejuvenation is best done in the spring. Awakening kidneys are pronounced, it is easier to highlight healthy segments.
In autumn, you can create compositions from early flowering varieties. They are transplanted in order to enjoy their lush flowering at the very beginning of next summer.
When can you transplant astilba in the spring
Spring awakening of astilba in the process of transplantation
Frosts recede, growth buds awaken – the plant is ready to be transferred to a site prepared in advance in the fall. Benefits of a spring transplant:
- successful survival;
- rapid growth of the root system;
- budding already in this season of medium-blooming and late species;
- prevention of diseases (strong immunity is developed).
This period is suitable exclusively for heel transplants.
When to transplant astilbe in the fall
The optimal time is the end of August or the beginning of September. The number of transplants depends on the completion of flowering and weather conditions, the disturbed plant must be given time to take root (at least 1,5 months).
In order for new bushes of early species to bloom at the beginning of the next season, they are also transplanted in the fall.
The dormant period of the culture is also suitable. Astilba can be transplanted in autumn even in October.
When to transplant astilba in the suburbs
Due to its biological origin, the culture easily adapts to the capricious climate of the Moscow region, it is well received in fertile soil. It is possible to transplant an adult astilba plant in the Moscow region from spring to autumn.
If the weather turned out to be warm and the snow melted early, then the bush is ready for transplanting at the end of April. In the usual spring, astilba begins to be relocated from the first days of May, the main thing is that its new location should correspond to the variety.
It is also possible to transplant astilbe in the fall to another place at different times. It is dug in late August or early September. If the earth has not yet frozen, and the air temperature has not dropped below + 5C, then October is also the right time.
When transplanting, experienced gardeners observe the lunar calendar. For better rooting, it is necessary to plant a crop in the ground on a growing moon and in a fertile zodiac sign.
Astilbe transplantation in October should take place in a waning phase so that the roots do not start growing.
When can astilba be transplanted to a new place in the regions
For the selection of cultivated varieties, wild species inhabiting the forests of North America and the Pacific Islands are used. Thanks to this, hybrids successfully decorate the gardens and parks of the northern regions, the middle zone and the south of Our Country.
The timing of astilba transplantation in autumn in Siberia and the Urals is completely dependent on the weather. Given the early onset of frosts, the end of August and the first week of September are considered the optimal period. Only then the transplanted flower will fully take root.
Spring planting of the northern regions is possible when the air warms up to +10оC, usually at the end of May. With a long spring, transplanting may be delayed until early June. This circumstance will delay flowering or even push it back to the next season. If there is no urgent need, then it is better to change the location of the astilbe in the fall.
In the mild climate of the south, an adult astilba plant is transplanted most often in April so that the adaptation period ends before the onset of heat. For an autumn transplant, October is the ideal time.
How to transplant astilba to a new place
Astilba is an unpretentious flower. It will grow anywhere in the garden. But in order to see the fullness of colors and enjoy them longer, you need to transplant astilba correctly.
Site selection and soil preparation
The location on the site depends on the type and variety, they are all shade-loving and moisture-loving. The scattered light of large trees is an ideal shelter from the scorching rays, but at the same time, species of light shades prefer more lit areas.
The best neighbors of the transplanted astilbe will be ornamental trees and shrubs, as fruit trees take a lot of moisture.
Astilba serves as a decoration for the root zone of large trees.
The plant feels great along the banks of reservoirs and wetlands, near fences and buildings.
Original astilbe as a border
The soil is preferably loamy, fertilized with humus, slightly acidic. Alkali in the ground is neutralized with dolomite flour and ash. Only for the next season, astilba can be transplanted to this new place. Heavy soils are diluted with sand, peat or compost at the rate of 10 kg/m2.
With a close occurrence of groundwater, drainage is placed in the planting pits, protecting the rhizome from decay. If moisture does not linger, and the soil dries quickly, it is advisable to put a hydrogel on the bottom, it will retain water and give it to the plant at the right time.
Hydrogel and drainage – reliable protection
The holes are not deep, about 20 cm. So the transplanted astilba will have a place to grow roots up. The diameter depends on the size of the root system, the pit should be 5 cm wider.
The top layer of soil dug out of the hole is mixed with rotted manure, a glass of ash and 20 g of mineral fertilizer. The seedling is then covered with this mixture.
How to dig and prepare astilba bushes
You have to move the plant in different cases, so the methods of transplanting also differ.
Methods and their implementation:
- Transshipment – used for emergency transplantation.
Carefully dig near the bush at a distance of 15-20 cm from the stems, remove the earthen ball and transfer it to a previously prepared place. Carefully lay in the hole so that the earth does not crumble, otherwise the suction roots will be damaged.
- Complete soil replacement – it is used during the transplantation of an adult astilba plant to another place, rejuvenation of the bush with the division of the rhizome into separate segments.
Dig up a flower, shake off the ground, rinse the roots with water. With a sharp sterile knife, cut them into pieces with 5-6 kidneys. Treat the sections with crushed coal or soak in a solution of potassium permanganate.
- Partial transplant. In early spring, without digging out the bush completely, several renewal buds with roots are separated. This segment is also called the “heel”. Treat both sections with ash. The maternal root is buried. Cut off – planted in another place.
The division of the root into segments should be done very carefully, with sharply sharpened tools.
If astilba was purchased from a distribution network and was stored in peat soil:
- the roots are thoroughly cleaned before planting;
- placed for a day in any growth stimulator, for example, Kornevin;
- washed in a pink solution of potassium permanganate.
And only then the delenki are transplanted into the ground.
Transplant algorithm
The transplantation process itself is not complicated and is carried out in several steps.
Stages | Necessary actions |
Site Selection | shaded, wet |
Soil preparation | Digging, weeding, fertilizing |
Planting pit work | Lay drainage or hydrogel (if necessary) at the bottom of the hole, fill it with soil to the middle, spill it with water |
Planting a rhizome | Place in a hole so that the growth buds are located 5 cm below ground level, straighten the roots, cover with soil, filling all cavities, compact |
Final works | Shed thoroughly, mulch with a layer of 5 cm |
Mulch will prevent the soil from drying out and the rapid spread of weeds. When transplanting several bushes, an interval of 30 – 40 cm must be observed.
Mulching is an important stage of care
Astilba care after transplant
The versatility of the flower does not require much attention other than regular watering, especially in the first year after transplanting. Annual top dressing with organomineral fertilizers will maintain the nutritional balance in the soil. Timely removal of weeds and mulching will prevent the roots from drying out. Shelter for the winter in a harsh climate will protect the astilba from freezing.
Conclusion
It is not difficult to transplant astilba if you listen to the advice of knowledgeable people. She is unpretentious and adapts easily. A competent transplant will prolong its life and flowering for a long time.
