Purple-leaf plum shrubs, also known as purple-leaf sandy cherry shrubs, grow red leaves in spring and purple leaves in autumn. To plant them as a hedge, you need a spade, compost, fertilizer and mulch.Continue Reading
Purple-leaf plum shrubs prefer full sunlight but can also handle partial shade. The soil must be well-draining. If the soil's pH level is higher than 7.5, add some ground rock sulfur 2 weeks before planting.
Dig holes as deep as the root balls and about two and a half times as wide. Amend the removed soil with organic compost and fertilizer. Place the top of the root balls at ground level. Fill in half the soil, water generously, and check the straightness of the shrubs. Then, fill in the rest of the soil, and tap it down to remove air bubbles.
Give the shrubs plenty of water after planting, and water them every other week to a depth of 10 to 14 inches. Before the main growth in spring, fertilize the plants. Add a 2- to 3-inch layer of mulch around the plants, not touching the trunks, to impede weed growth and help retain moisture. Purple-leaf plum shrubs are vulnerable to borers, aphids, Japanese beetles and other pests, so watch for infestations, and apply insecticide as needed.
