The root system of the astilbe is of great importance. Not just because it has to get a lot of water from the earth. Planting often only begins with the roots. Keeping it he althy later on is the primary task of every owner.
Appearance and Function of Astilbe Root
The Astilbe does not have a typical root, buta richly branched, vertically growing rhizomeFine roots grow from its nodes, which cover the plant's water and nutrient needs. In addition, runners form on them, which ensure that the plant spreads.
What does the root system of astilbe look like?
The astilbe hasno normal roots, but forms verticalrhizomes Roots grow from its nodes and sprout runners, which is how the plant grows can supply and spread. The root system remains directly below the surface of the earth. Every spring new growth appears. Even after a radical cut in spring, the astilbe sprouts vigorously from the rhizomes.
How do astilbe roots stay he althy?
The soil around the roots must beconstantly moistso that they do not dry out. Because then the above-ground part of the astilbe would also dry out. But there must also beno waterlogging around them, then rot will occur. The following are therefore important:
- shady to shady location
- Watering as soon as the top layer of soil dries
- a thick layer of mulch to protect against evaporation
The roots also need a lot of nutrients so that the perennial can spread with their help. The ideal fertilization: plenty of compost in spring.
What are the advantages of commercially available bare-root astilbe?
The root product enables the provider to save space in storage and make shipping easier and more cost-effective. There are two plus points for the buyer:less plastic wasteandbetter growth all year round in the bed than with astilbe in the pot.
How do I plant purchased root products?
Planting astilbe root is very easy, but should be doneimmediately. As soon as you hold the bare-root astilbe that you bought or ordered locally, proceed as follows:
- immediately open protective film
- check the condition of the roots, especially moisture
- moisten roots if necessary
- shorten damaged copies
- dig a depression at the site
- Insert roots and cover with excavation
- the uppermost part of the root should bejust below the surface of the earth
- finally pour
- start optimal care immediately
How do I propagate astilbe from roots myself?
You can dig up an astilbe that has become too large and may have bare spots insidein the springand divide therhizome. Plant varieties that can reach great heights at least 50 cm apart, low-growing ones at least 25 cm.
Tip
Support the establishment of roots with compost
In order for your own propagation from roots to be successful, you should carefully dig out the root system of the astilbe so that it is not damaged. A handful of compost in the new planting pit provides the first growth spurt.
