- Container Growing: Adding diluted liquid fertilizer once every 6-8 weeks during the growing season promotes more abundant flowering.
Pruning and aesthetic maintenance
La regular pruning It is essential to maintain the compact shape, health and abundant flowering of Perovskia atriplicifolia.
- Ideal time: The most severe pruning should be done at late winter or early spring, before new shoots appear. You can cut the stems to a height of between 20 and 30 centimeters (approximately 6 to 12 inches) to encourage thick branching and prevent excessive wood formation.
- Pruning for cleaning: Remove wilted flowers, dry or damaged stems throughout the season to prolong flowering and improve appearance.
- Formation pruning: If you want a denser bush, pinch the terminal stems after the first bloom to encourage new growth.
- Avoid pruning in autumn: It can induce tender regrowth that may be damaged by early frost.
- Take advantage of pruning remains: Young stems and parts of the woody stems can be used to multiply the plant by cuttings.
Multiplication and propagation
La Perovskia atriplicifolia It reproduces easily by three main methods:
- Cuttings: The easiest and quickest way. Use young stems from spring or fall, cut them to about 8-12 cm, remove the lower leaves, and plant them in a light, moist substrate (peat and sand or perlite). Keep them in semi-shade and with constant moisture until they take root. Transplant to their final location once they develop strong roots.
- Seeds: Sow in spring in a protected seedbed. Germination takes 2-3 weeks at temperatures between 15-20 °CAfter forming seedlings, carefully transplant them into the garden. This method is ideal for growing many plants and different varieties, but flowering may be delayed until the second year.
- Division of bushes: Perform this procedure in spring or fall, separating rooted portions and several shoots. It is effective on adult plants that have formed large clumps or on specimens that have spread by stolons.
If Perovskia begins to spread beyond the desired limits (via underground runners), you can remove unwanted shoots in spring to control its spread. For more information, see how to Perovskia atriplicifolia care.
Pests and diseases: prevention and solutions
