Curling Tomato Leaves on Top

Question

Why are my tomatoes curling up at the top in my greenhouse while the lower leaves are well?

Answer 1

You may be watering just a bit too much. When tomatoes get a bit too much water, but have good drainage, their leaves may roll up. The leaves will also feel a bit leathery. This condition is not overly harmful to the plant and should clear up over time.
