Squash Blossom End Rot Caused By Low Calcium Content Of Soil?

The problem with low calcium content of soil is that it causes blossom end rot. The reason is because when there’s not enough nutrients in the soil, the plant doesn’t have enough energy to grow properly. If the plant gets too much energy from the nutrient deficiency, then it will start growing abnormally fast or even burst into bloom before its time.

It’s very common for people to think that if they apply more fertilizer, the problem will get better. But unfortunately, adding too much fertilizer may cause the problem to worsen instead of getting better. The best thing you can do is to keep your soil balanced with calcium and phosphorus (and other elements) so that the plant gets enough energy.

That way it won’t suffer from blossom end rot!

How To Fix Blossom End Rot?

There are several ways to fix blossom end rot. You can buy a product called “zucchini blossoms” which contain calcium sulfate (or some other form of calcium). Or you can use a natural remedy such as Epsom Salt.

Zucchini Blossoms Are Not A Solution For Blossom End Rot!

A good alternative is to make your own homemade lemon juice and sprinkle it around the base of your squash plants. This is good because it doesn’t need much effort or any special equipment. The downside is that it takes a little time before you see results.

Epsom Salt Is A Natural Blossom End Rot Remedy!

Another great natural remedy for blossom end rot is to make your own epsom salt solution. This is fast acting, but it can be a little messy so take precautions to avoid spilling it on the floor.

Make A Calcium Solution For Blossom End Rot!

You can make your own calcium solution by mixing one tablespoon of epsom salt in one gallon of water. Soak the blossom end of each zucchini plant in this solution every couple of days. You can also use a spray bottle to apply the mixture to the base of the plant.

In a week or two, you should start seeing a difference. Blossom end rot is caused by a calcium deficiency, so supplementing with the epsom salt will cure it.

While blossom end rot is a very common problem, it’s also one of the easiest problems to fix. Just remember you need to cure the actual cause of the problem (which in this case is a lack of calcium) to solve it once and for all.

Using a spray with seaweed extract in it (but this is only available at garden centers).

Feeding them with a special blossom end rot enzyme formula (but this requires you to make a trip to a garden center or buy it online).

Buying a different fertilizer that has more calcium in it.

Poke a hole in each zucchini with your finger and put 3 drops of fish oil in each hole. This is supposed to act as a fertilizer and grow healthy blossom without the blossom end rot.

Give the plant extra water. This won’t make the blossom rot go away, but it will make them taste better.

Apply wood ashes to the base of the plant (but only use this as a last resort because it can cause other problems with the plants).

To Sum It Up!
