1. Appropriate cultivation and management measures should be adopted based on the growth habits of different varieties of perennials, including their flowering, fruiting, and overwintering dormancy.
2. After perennials bloom, it's important to prune off any dead stems, flowers, and fruits from varieties that do not bear fruit.
3. Once herbaceous flowers enter dormancy, it's important to promptly remove withered stems and leaves from the above ground parts.
4. For perennial flowers with root clumps, it is advisable to adjust the planting density and replant by division during the dormant period.
5. In winter, it's advisable to add soil and conserve moisture for perennials with poor cold resistance.
6. Prune herbaceous perennials prone to lodging at the appropriate time. For perennials that bloom twice (such as Sedum, Sedum), prune after the first flowering.
7. During the growth period, rhizome flowers should be top-dressed or foliar-fed.
8. Watering should be timed according to soil moisture conditions. Varieties that prefer moisture should maintain adequate water supply during the growing season. Perennial flowers require watering for greening up and frost protection.
