Lots Of Flowers On Watermelon Vines But Only Couple Of Teeny Melons – Zone 8b

Question

Zone 8b – About 3 months ago I planted four watermelon plants. They have taken off beautifully and are covered with lots of flowers. The problem is I only see two or three teeny melons starting to grow and they don’t seem to be getting larger. Over time I have occasionally moved the end of a few vines to keep them more in a central area — could that be the problem, too compact? We’ve gotten rain almost every day for going on two weeks now so I know they’re happy with watering. I’ve fertilized them once with a granule type fertilizer for fruit and veg. Any suggestions would really be appreciated. Thank you so much.

Answer 1

It could be the heat. This can prevent melons from forming properly.

Alternatively, there could be too much nitrogen in the soil. Phosphorus and potassium can help to offset the nitrogen.
