| Late winter–early spring |
Dormant-season treatments, inspection, and selective pruning before heavy growth. |
Overwintering pests on bark/buds, cankers, deadwood, weak branch angles. |
Pruning at the wrong time or cutting too aggressively “because it looks big.” |
| Spring |
Growth support, irrigation tuning, and early pest pressure checks. |
Bud break health, leaf quality, early insect feeding, soil moisture consistency. |
Overwatering “to help it green up,” which can stress roots and invite problems. |
| Summer |
Heat-stress prevention, deep watering strategy, and targeted insect/disease control. |
Leaf scorch patterns, canopy thinning, insect hotspots, irrigation coverage gaps. |
Frequent shallow watering that never reaches the active root zone. |
| Fall |
Root support, winter prep, and watering adjustments before freeze. |
Late-season stress, pest carryover risk, need for corrective pruning planning. |
Shutting irrigation down too early while soils are still warm and dry. |
