The redhumped caterpillar is a familiar pest on fruit and nut trees such as plum, almond, cherry, and apple, as well as on ornamental trees like liquidambar and birch. It can reach high populations in California's Central Valley, sometimes defoliating entire trees.

Peach leaf curl is a disease that affects peach and nectarine trees. Although you may not see symptoms right now in the dormant season in California, it's time to think about treatment, especially if your tree had the disease last year.

Winter is an ideal time to prune deciduous fruit and shade trees, since the trees are dormant and you can more easily see the tree canopy. In many cases, pruning can also help prevent or control certain insect and disease problems.
