Seasonal Tree Care Calendar for the Sierra Foothills
Northern California’s foothill climate — wet winters, long dry summers, and real fire and storm seasons — means tree care is a matter of timing as much as technique. Doing the right task in the wrong season can spread disease or stress a tree; doing it at the right time prevents most of the emergencies we get called out for.

Spring
As the rains taper off and growth begins, spring is for assessment and cleanup after winter.
- Inspect trees for winter storm damage and hanging or broken limbs.
- Prune dead, diseased, or damaged branches before the growth flush.
- Begin regular watering as the rains decrease.
- Plant new trees during the early spring window while soil is still moist.
Summer
Summer is about keeping trees hydrated and watching for stress, not heavy pruning.
- Monitor soil moisture and increase watering during heat waves.
- Watch for insect damage and disease, especially bark beetles in stressed pines.
- Avoid heavy pruning during peak heat — it stresses the tree and invites pests.
- Mulch to retain moisture and regulate soil temperature.
Fall
Fall is the time to get ahead of winter storms and complete defensible-space work.
- Continue watering until the first hard frost.
- Consider structural pruning before winter storms load the canopy.
- Remove fallen leaves and debris from tree bases.
- Plant deciduous trees during fall dormancy.
Winter
Dormancy is the ideal window for major pruning and removals on most species, and storm season is when hazards show themselves.
- Schedule structural pruning and removals while deciduous trees are dormant.
- Inspect for storm damage after heavy winds, snow, or ice.
- Protect young trees from frost.
- Minimal watering during dormancy.
