When Should I Prune Fruit Trees in Santa Cruz?
Prune deciduous fruit trees while they are fully dormant, which in Santa Cruz County means late January through mid-February for most varieties.
The goal is to prune after the coldest weather has passed but before the tree breaks dormancy and starts pushing new growth. Pruning too early (December) can expose fresh cuts to freeze damage on cold nights in areas like Scotts Valley or the San Lorenzo Valley. Pruning too late (March) means you're cutting off energy the tree has already invested in new buds. The UC Agriculture and Natural Resources pruning guide recommends pruning stone fruit (peaches, plums, cherries) in late January and pome fruit (apples, pears) in February, since stone fruit breaks dormancy earlier.
The exception is apricots. Prune apricots in late summer, after harvest, to reduce the risk of Eutypa dieback, a fungal disease that enters through wet-season pruning cuts. This is especially important in Santa Cruz's damp winters.
For citrus and other evergreen fruit trees, light pruning can happen almost any time, but avoid heavy cuts during winter when the tree is growing slowly. Wait until after the spring flush for major shaping.
When you prune, focus on removing dead wood, crossing branches, and anything growing straight up (water sprouts). Open the canopy to improve airflow and light penetration, which reduces disease pressure in our foggy climate.
This week: Sharpen your pruning tools and disinfect them with a 10% bleach solution or isopropyl alcohol. Clean cuts heal faster and spread less disease.
