Why Do Squashes Rot on Vines?
Squashes are a popular vegetable in many households due to their versatility in cooking and various health benefits. However, growing them can be a challenge for some, especially when the fruits start to rot on the vines.
This can happen for a variety of reasons, including poor soil quality, pest infestations, and diseases. Here are some of the most common causes of squash rot:
- Lack of Calcium
One of the main reasons for squash rot is a calcium deficiency in the soil. Calcium is an essential nutrient for plants, and without it, they can’t develop properly. This can lead to a host of problems, including poor fruit quality and susceptibility to diseases.
In the case of squashes, a lack of calcium can cause blossom end rot, a condition where the bottom of the fruit becomes mushy and black. 
- Fungal Diseases
Another common cause of squash rot is a fungal disease. One such disease is gummy stem blight, which is caused by the fungus Didymella bryoniae. This disease causes black, sunken lesions on the stems and fruits of the plant, which can lead to the fruit rotting on the vine.
Another fungal disease that can cause squash rot is powdery mildew, which is characterized by a white, powdery coating on the leaves and stems of the plant. This disease can weaken the plant, making it more susceptible to rotting. 
Pests can also contribute to squash rot by damaging the fruit, allowing fungi and bacteria to enter. One such pest is the squash bug, which feeds on the sap of the plant and can cause wilting and discoloration.
Another pest that can cause squash rot is the squash vine borer, which lays its eggs on the stems of the plant. When the eggs hatch, the larvae tunnel into the stems, causing them to wilt and eventually die.
