| Leyland Cypresses are easy to grow and are among the fastest growing evergreens around. They need well draining soils and a deep soaking once a week. You can feed your plants with an 8-8-8 time release fertilizer each spring and to encourage healthy new growth you can shear or prune them back each spring. Aside from this general maintenance, not much else needs to be done to keep your cypresses healthy. Bagworms are probably the worst insect pest and on small trees Bagworms can be picked by hand but larger trees need to be sprayed. Dimethoate which sells under the trade name Cygon, works well when applied in the first 3 months of spring, when the larvae are small and before they produce bags. After they produce bags they are very difficult to control with chemicals. Hope this answers your question. |
