Caused by two fungi – Cylindrocladium buxicola (syn. Calonectria pseudonaviculata) and Pseudonectria buxi
Fungal disease that affects Buxus species (Box). The disease causes leaves to brown and fall off, causing bare patches. It can also infect young stems and cause black streaks and dieback. In damp conditions the spore masses may be visible on the lower side of infected leaves (white for C. buxicola and pink for P. Buxi).
Healthy plants growing in healthy soil are less susceptible to infection. Improve soil health by mulching around your plants with Living Earth More Than Mulch regularly with Kings Sheep Pellets and Novatec Premium.
Water regularly through the drier months, but avoid overhead watering. A deep water 2-3 times a week is better than regular shallow watering. Adding Aquatics Garden Booster to the water will provide healthy roots and strengthen plants. The addition of Saturaid into the soil will help channel water down to the root zone where it is needed.
When planting new plants add Rootmate to the base of the roots.
Early intervention and good hygiene practices are the key to managing Buxus Blight. At first sign of any leaf browning or leaf discoloration treat with Plantmate.
Overhead watering is a no no, as the spores of the fungus are spread by water splash and re-infect plants in water droplets, mulching under the base of plants will reduce water splash.
Clean up any fallen dead or dying leaves from the ground as these will produce more spores and can live in the soil for up to seven years. Do not place into your compost.
Prune out infected limbs. Sterilise pruning equipment with methylated spirits between plants.
Clear away all leaf litter from under the plants.
Spray foliage with Buxus Blight Fighter, and drench around the roots.
When using sprays and chemicals always read the label and follow instructions carefully.
