The Q&A Archives: Yellow Squash Rot

Question: I have a yellow crook neck squash that grows about 4 inches, and then the end starts to rot. Some of the squash grow well, but some rot. I am not watering from above and I do see a few bees in the garden .

Answer: If a water-soaked, sunken spot develops on the blossom end of squash, it usually indicates one or more of the following: lack of calcium uptake, extreme fluctuations in soil moisture, rapid early season growth followed by dry weather, excessive rainfall, or excessive salts in the soil. To avoid, try to keep the soil evenly moist, don't overfertilize, plant in well-draining soil, and don't cultivate too close to the ripening fruit (to avoid damage and allow introduction of bacteria). Remove the affected fruits and destroy them, to give the plants an opportunity to develop more fruit.
