Improve the Health of Box Topiary and Hedging with Regular Mulching

Spring is the perfect time to mulch underneath box hedging and topiary. Mulching is an excellent way to improve the health of box and encourage thicker, bushier growth. Buxus sempervirens has a very shallow, wide-spreading root system. Soil around the base of box will be disturbed and removed overtime by weeding, watering and Winter weather conditions.

A regular application of mulch every Spring is a good way to protect the roots and help retain moisture in the soil during…

Simple Plastic Bag Test to Diagnose Box Blight

So far this approach has had good success. The fungicide helps stop the infection getting…
