The structural season. Prune deciduous trees and shrubs while you can see the architecture. Limb-up oaks. Renew gravel beds.
- Limb up trees to 6 ft clear trunk
- Renew DG and gravel mulch in Zone 0
- Inspect roof, gutters, vents
- Plan plant additions for spring
Plant. Establish irrigation early so new plants are deep-rooted before drought. Light pruning to shape.
- Install new plantings before May
- Pressure-test drip lines
- Mulch all beds (mineral, never bark within 5 ft)
- Shear lavender and santolina lightly
Vigilance. Deadhead, hydrate, and edit anything that looks tired. This is the season your garden earns its name.
- Deadhead salvias, yarrow, lavender
- Remove all dead material weekly in Zone 0–1
- Mow native grasses in Zone 2 to 4″
- Confirm 100 ft defensible space is clean
Cleanup, then rest. The single most important season for ember resilience.
- Deep clean gutters and roof valleys
- Cut perennials back; haul away cuttings
- Move firewood 30+ ft from any structure
- Photograph the garden for next year's plan
