| Humidity | At least 30%, happiest near 50% |
| Temperature | 65–95°F. Cold damage below 30°F; heat stress in sun above 105°F. |
| Feeding | Every ~30 days while actively growing. Nothing in winter. |

What people get wrong about citrus
Yellow leaves with green veins is iron/micronutrient chlorosis — feed a citrus-specific fertilizer with micronutrients, not more nitrogen.
Potted citrus needs feeding far more often than in-ground citrus.
Common problems
Watch for citrus leafminer, aphids, scale, spider mites, whitefly. Check leaf undersides monthly — backlighting a leaf against a window is the fastest way to catch mite webbing before an infestation takes hold.
Plantroster tracks this plant's watering, feeding and repotting cadence against your actual weather — and tells you when a cold night or heatwave means moving it.
Open PlantrosterCitrus FAQ
How often should I water a citrus?
Roughly every 4 days in the growing season and every 12 days in winter, but treat that as a starting point rather than a rule — light, pot size and your home's warmth all shift it. Deep, regular watering — inconsistent moisture causes fruit split and leaf drop. Never waterlogged.
Is citrus toxic to cats and dogs?
Yes. Citrus oils in peel and leaves are toxic to cats and dogs in quantity. Keep it out of reach of pets that chew plants.
How much light does a citrus need?
Full sun is ideal, and it will cope with full sun. 8+ hours of direct sun for real fruit.
Why does my citrus have brown tips?
Citrus is not fluoride-sensitive, so brown tips here usually point to inconsistent watering or fertilizer salts built up in old soil. Flush the pot thoroughly and keep to a steadier watering rhythm.
What soil is best for citrus?
Fast-draining succulent mix: 4 parts potting mix, 4 parts pumice, 2 parts sand. Succulents and dracaenas rot in moisture-retentive mixes. Grit is the whole point.
