Care of the rhizomatous plant Astilbe x arendsii or Astilbe hybrid |
|
The genus Astilbe, family Saxifragaceae, comprises 18 species of rhizomatous herbaceous plants native to Asia and North America. Some species are: Astilbe chinensis, Astilbe japonica, Astilbe thunbergii, Astilbe crispa. Common names: Astilbe hybrid, False spiraea. This cultivar was produced by breeders in Germany and Holland. They are fast growing rhizomatous plants that reach 1 meter (3.28 feet) in height. The interesting foliage is formed by bright green serrated margin leaves. The attractive flowers appear in feather-like panicles and can be pink, cream, magenta, white, or red. The flowers last long on the plant. They are used in pots for terraces, as a houseplant and for cool areas of the garden under trees or shrubs, either in groups or as isolated specimens; They are also highly recommended for planting next to ponds or water courses. Astilbe x arendsii prefers a semi-shade or shade exposure in hot climates (Mediterranean); if the climate is cooler it can be grown in full sun. They do not tolerate intense and continuous frosts, so it is advisable to mulch the ground with straw or pine bark to protect the roots. They need a drained and acidic soil, that is, it contains enough organic matter. Use a commercial substrate for houseplants with a little compost. In case of transplant, it is advisable to do it in early spring. Water regularly (never overwater) so that the soil is always wet. They do not resist drought. Fertilize in the fall with compost and in the spring with a mineral fertilizer for houseplants. They can be lightly pruned after flowering to remove wilted flowers. In cold regions (with frost) it is recommended to prune almost the entire aerial part to protect it from the cold; will sprout in spring. The worst enemies of these plants are drought and over-watering that powdery mildew (fungi) can produce. They propagate by division in late winter once the danger of frost has passed. |
