Zucchini Rotting on the Vine


I would like to know why my zucchini plants look great with lots of flowers and fruit but when the zucchini get about 3-4 inches they start to rot or go soft? The first fruit I picked was great but since then they have not been good! Thank you.


Hardiness Zone: 6a

Sounds more like blossom rot. (BER) That is a sign of lack of calcium. A few possible solutions to cure it.

  1. Egg shells, best added when you place them underneath the plant at planting time; but you could add into the soil whenever to gradually bring up traces of calcium. I grind my egg shells until a fine powder and add to the soil and water.

  2. Liming the soil with calcium carbonate (crushed limestone). Best in the winter or off season, or before planting.

  3. There are commercial sprays available (calcium nitrate & calcium chloride) that you can spray on or around the plants themselves during the growing season.

  4. Grind up a couple dozen calcium citrate dietary supplements, dissolve it in water and water your plants. This will affect all the new fruit.
