Shade clematis roots Clematis thrive in fertile, well-drained soil in sun or partial shade, but ensure the roots and base of plants are in the shade to keep them healthy. Blackened shoot tips may indicate clematis wilt. Cut out affected stems, but leave the main pruning until late winter and early spring. Roses Regularly deadhead roses, trimming the flowers off just above the uppermost leaf on the stem. Carnations Pin any low stems to the ground with a metal peg to layer them and raise new plants.
Lilies Tie tall stems to canes for support and watch out for lily beetles and their larvae.
Pick any off and destroy them immediately. Gladioli Prevent thrips from damaging foliage and flower-heads by spraying plants with malathion. Dried flowers Cut everlasting flowers, such as helichrysum and achillea, and grasses, such as pennisetum, when they are at their peak. Hang them upside down in a warm, airy position to dry naturally, ready for decorative arrangements. Once the flowers have passed their best, trim the bushes lightly to remove the old blooms and shoot tips.
