what causes leaf curl on pomegranates
Only a small part of the leaves are curled on my pomegranate tree.
Leaf curl can be caused by disease, insects, water and/or nutrient imbalance; or it can be totally natural and innocuous. Diseases will be accompanied by spotting, browning, or discoloration of the leaves. Insects will be very small and attached to the underside of the leaves where they can be scraped off, or they might be flying or crawling around. Examine the leaves very closely.
Pomegranates like well drained soil and full sun; other than that, they don't seem very fussy. This article has growing information: https://aggie-horticulture.tamu.edu/citrus/pomegranate.htm
