Using Science to Enrich Beautiful Landscapes
Yews are a good traditional shrub with rich color. The two main types to choose from are “Densi” which grow low and wide or “Hicksi” which grow vertically. The biggest problem with yews people don’t realize is that its very easy to over water them and cause Phytophora Root Rot. Once established, you shouldn’t need to water them at all during the summer months. Where homeowners make mistakes is when they plant flowers near these hedges which require everyday watering. Smart irrigation design work is key to isolating where water needs to be placed avoiding those areas it should not. As the second picture shows, this hedge is deteriorating, turning yellow and thinning out, due to too much water in the soil. A soil fungicide will help stabilize the Yews however if poor watering practices continue then expect complete loss.
