Blossom end rot is not caused by organisms like many plant diseases. It is usually caused by environmental conditions which include long periods of wet weather followed by dry weather or deficient calcium in the soil. There is not much that you can do to save the affected veggies. You just have to pull them off the vine and hope that it does not continue. There are a few things that you can do to help prevent the rot before planting:
- Test the soil before planting. I should have done this with my garden since we have new soil. The bed that was affected was the one without the compost since we ran out. I think that the soil probably needed lime for additional calcium. If the dirt was not acidic enough, then I should have added gypsum for acidity.
- Mulch around the plants to help hold moisture. My uncle gave us some straw pads that his baby turkeys came with in their crate. The pads should help with both weeds and moisture.
- Avoiding extra fertilizing helps with the pH levels.
