Favorite or New Plant

Yarrows are rugged flowering perennials that do best in average soils, be it sand or clay. If you have a habit of fertilizing your plants frequently, yarrows are not for you. Too rich soil or too much nitrogen results in floppy leaves and stems and few flowers. It is important to deadhead the fading flowers after the first flush of blooms. This will encourage more flowering throughout the growing season. One of my favorites is the variety called 'Paprika' (Achillea millefolium 'Paprika'), with its reddish-orange blooms. They have a fuzzy, fern-like foliage that adds texture to the landscape and in the background of perennial flower beds. This utility perennial grows from 15 to 20 inches tall with a spread of 18 to 24 inches. Plant in a area that gets full sun and the soil is well drained.

Clever Gardening Technique

Avoid the Pruning Paints and Sealants
As we tidy up the garden and prune trees and shrubs, don't be tempted to apply pruning paints and wound sealants to the cut ends. These materials will only inhibit the natural closing or "healing" of the pruning wound. Plants are equipped to deal with pruning wounds without artificial Band-Aids.
