Spray your benches and work area with a fungicide and an insecticide to destroy lingering infectious pests. Feeding conifers and other evergreen trees during the winter months is a common practice in the warmer areas of California. Trees in stages of dormancy are actually still growing and require some nourishment. Remove covers of moss from potted trees. Excess moss will harbor insects and disease.
Excess moss holds moisture at dangerously high levels.
Removal will encourage better drainage, an increase of beneficial oxygen to the roots and warm the root ball. Winter is a good time to nursery hop - looking for new material to train and enjoy next year. Look for plants that did not sell during this past year. They may often be bargains. This is also a good time to add to your rock collection.
