Sun and Temperature
For best results, grow in full sun and keep temperatures above 40°F. If grown in warm conditions with high light intensity, Curry Leaf will experience less of a winter resting period.
During the winter resting period, do not keep the plant too wet, especially if the leaves have dropped. Too much water will tend to promote root disease (root rot). During the warmer months, keep the plant on the dry side. Let the soil come to visual dryness before watering. We recommend growing in clay pots so the roots stay healthy. Use a well-drained potting mix. This allows necessary moisture to reach the plant while at the same time maintaining good aeration in the soil. We have also found that a slightly acidic soil keeps the plant healthy. Regular applications of fertilizer are helpful to stimulate plant growth. You can top dress with organic fertilizer every 6 weeks or apply a liquid fertilizer at half the recommended dosage once a week during the active growing season.
Curry Leaf can experience interveinal yellowing (chlorosis) on its leaves during the wintertime. Cool temperatures seem to be the major factor for this leaf problem. It often indicates that the plant may be getting ready to go into dormancy. If you increase the temperatures, you can slow or prevent dormancy or loss of leaves. If your Curry Leaf plant loses its leaves and only has a bare stem, cut back on watering and wait for winter to end. Your plant is fine. It’s simply resting. The leaves will re-grow in spring.
