Leaves Rolling at Tips

Question

My potted grapefruit tree has leaves at the top that are rolling at the tips. The bottom leaves are nice and flat. What is wrong, and how do I fix this problem?

Answer 1

If the leaves turn black and curl up, the plant is probably being kept too cold. It prefers warm, tropical-like temps. If the leaves stay green but curl up, that is a sign of too little light. Try and keep the plant in full sun at least 4-6 hours a day for best results. This article will help: https://www.gardeningknowhow.com/edible/fruits/grapefruit/growing-grapefruit.htm
