Why Are My Squash Bumpy

Rapid growth, boring insects, and excess calcium in soil may contribute to lumpy squash plants. However, the majority of these fruit deformities are the result of a mosaic virus. There are many types of mosaic strains that occur in different fruit families.

Can you eat bumpy squash?

Yes, you can eat squash and melons that are infected with mosaic virus. These viruses are not harmful to humans and do not cause the fruit to rot. Often the discoloration is only skin deep. In cases where fruit are severely distorted, the texture of the fruit may be affected and may not be desirable for eating.

What causes deformed squash?

Answer: Misshapen fruit may develop if pollination is inadequate. When pollination is incomplete, the fruit develops unevenly because the ovary wall enlarges more adjacent to fertilized seeds. Inadequate pollination may be due to low pollinator numbers or unfavorable weather.
