They have a different look in each season before, during, and after flowering. Small envelopes of seeds collected from your favorite perennials make a thoughtful gift to enclose in your holiday cards. Label the envelope with the collection date and the name of the flower. As you pore over the catalogs or read gardening magazines, jot down the names of perennials that are worth growing in your garden. This is a great time to have your soil tested at your county's Clemson Extension office.
Most perennials benefit from a boost with fertilizer as new growth begins in the spring.
Select a slow-release fertilizer according to soil test results. Follow the label directions regarding the amount and frequency of application. Water the fertilizer in to make it available to the plants. Place the stakes close to the plant, but take care to avoid damaging the root system. Secure the stems of the plants to stakes in several places with paper-covered wire or other materials that will not cut into the stem.
