Citrus care calendar — zone 9

The year at a glance

1. February

   • Light pruning — deadwood & suckersPrune · Feb 1 – Mar 31

     Citrus needs little pruning. After the main freeze risk has passed in late winter to spring, remove deadwood, crossing branches, and any suckers or watersprouts arising below the graft union. Avoid heavy cuts, which expose bark to sunburn.

   • Fertilization timingCare · Feb 1 – Aug 31

     Citrus are heavy feeders that respond to nitrogen split across the active growing season, typically beginning in late winter to early spring and continuing through summer, then easing off in fall so new growth hardens before cold. This entry marks the general timing only; follow local guidance for amounts.

2. March

   • Bloom & fruit-set awarenessNote · Mar 1 – May 31

     Most citrus bloom in spring and are self-fruitful, though some mandarins set better with a pollinizer nearby. Bees are active during bloom. A natural 'June drop' of excess small fruit afterward is normal. Awareness/timing only.

3. April

   • Post-bloom pest-monitoring windowSpray timing · Apr 1 – Jun 30

     The flush of new growth after bloom is the timing reference many extension calendars use to begin scouting citrus for scale, aphids, and leafminer on tender shoots. This entry marks the window only.

     Timing window per the cited source. For product and rate guidance, consult your local Cooperative Extension and always follow the label.

4. November

   • Harvest windowHarvest · Nov 1 – Mar 31

     Citrus ripen slowly and hold on the tree, so harvest is spread over weeks to months and varies widely by type: many oranges, mandarins, and grapefruit ripen fall into winter, while lemons and limes can carry fruit much of the year. Taste to judge ripeness—color alone is not reliable.

5. December

   • Frost / freeze protection windowCare · Dec 1 – Feb 28

     Citrus is cold-sensitive; the winter months are when freeze protection matters. Before a hard freeze, water the root zone, cover the canopy, and add heat or wrap young trunks; hardiness varies by type (limes and lemons most tender, satsuma and kumquat most hardy). Awareness/timing only.
