Regional Notes

Catkin blast causes catkins to die and drop prematurely from infected trees. You notice loss of flowers before opening or shortly after catkin emergence. The fungal disease affects seed and fruit development significantly. Manage through sanitation by removing infected catkins when spotted and improving air flow.

Management depends on catching it early. Scout susceptible plants regularly and remove affected tissue before the pathogen can spread. Improve growing conditions by addressing drainage, spacing, and irrigation practices. For persistent or severe cases, contact your local Master Gardener program or Extension office for treatment options specific to your host plants.
