Many Yellow Curled Leaves

Question

I have a potted grapefruit tree. The cause may have been putting it out too early (a slight freeze) or my stupid watering/not watering regimine, but it has lost about 20% of its leaves. About 3/4 of the remaining leaves are sort of a lighter green and curled. It is potted in Miracle Grow citrus potting soil. The soil is pretty moist right now. What to do?

Answer 1

It might need fertilizer. Even planted in fertilize potting soil, they need fertilizer regularly to replenish what gets washed out when watering and just what they use. This article will help:
