How to Manage Pests

Pests in Gardens and Landscapes

Normal dormancy

Foliage discolors, turning yellow and brown and eventually drops. California buckeye goes dormant in the summer. Leaves often remain on trees for weeks or months. Under drought conditions, leaves may brown and drop sooner. For larch trees, needles normally drop in the fall.


No control is necessary as foliage discoloration and drop is part of the normal dormancy process.
