How to GrowKeep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their germination. Mulches also help retain soil moisture and maintain even soil temperatures. For perennials, an organic mulch of aged bark or shredded leaves lends a natural look to the bed and will improve the soil as it breaks down in time. Always keep mulches off a plant’s stems to prevent possible rot.Careful watering is essential in getting perennials off to a good start. Water thoroughly at least once a week to help new roots grow down deeply. Soil should be damp at about 1 inch below the soil surface. You can check this by sticking your finger in the soil. Water early in the morning to give all leaves enough time to dry. One inch of rain or watering per week is recommended for most perennial plants. You can check to see if you need to add water by using a rain gauge.Until plants become established, some protection from extreme winds and direct, hot sunlight may be necessary. Good air movement is also important.After new growth appears, a light fertilizer may be applied. Keep granular fertilizers away from the plant crown and foliage to avoid burn injury. Use low rates of a slow release fertilizer, as higher rates may encourage root rots.“Deadhead”, remove spent flower heads to encourage continuous flowering and prevent seed development.Remove and discard foliage after a hard frost in fall. Pinch back plants before mid-July to control plant height and encourage branching.Cut back to the ground after blooming to reduce self-sowing and remove old foliage.Some varieties may benefit from staking.Divide plants when they become crowded in spring. TipsMany gardeners do not cut back perennial flower seed heads in the fall, but wait until early spring before the new foliage appears. This provides food for wildlife over the winter.For flower arranging, cut when blooms are opening to fully open. Show more
