Squash Blossom End Rot Causes And Treatment
While blossom end rot is commonly thought of as a problem that affects tomatoes, it also affects squash. Squash blossom end rot is frustrating, but preventable. Let's look at the some blossom end rot treatment tips.
Causes for squash end rot

The causes for squash end rot are simple. Squash blossom end rot happens due to a calcium deficiency. Calcium helps a plant create a stable structure. If a plant gets too little calcium while the fruit is developing, there is not enough to sufficiently build the cells on the fruit. In particular the bottom of the fruit, which grows the fastest, does not get enough calcium.

As the fruit gets larger, the cells begin to collapse, starting with those weakest cells at that bottom. At the location of the squash blossom, rot sets in and a black indentation appears.

While the causes for squash end rot will not make the squash dangerous to eat, the lack of calcium frequently causes the fruit to mature to early and the squash will not taste very good.
Blossom end rot treatment

There are a few things you can try for blossom end rot treatment. Keep in mind that all of these treatments must be done before squash blossom end rot appears. Once the fruit is affected, you cannot correct it.

Water evenly If the plant goes through drastic changes in the amount of water it gets, it may not be able to take up the calcium it need at the crucial time when the fruit is being formed. Water evenly, not too much or too little.

Add the right kind of fertilizer Add a low nitrogen fertilizer to the soil before you plant. Too much nitrogen will cause an imbalance of growth between the roots and the leaves. If the leaves grow too fast, the plant does not have enough roots to take up calcium the squash fruit will need.

Add lime The soil pH must be between 6.0 and 6.5 for optimal calcium uptake. Use lime to balance you're your soil's pH if it is too low, adding lime will correct this.

Add gypsum Gypsum will help add calcium to the soil and will make that nutrient more readily available.

Remove the fruit and fix the problem If squash blossom end rot appears, remove the affected fruit and use a calcium rich foliar spray on the plant. This will ensue that the next round of squash that the plant grows will have sufficient calcium to grow correctly.

The causes for squash end rot are very simple and blossom end rot treatment is easy enough when you know the source of the problem.
