What not to do with banana peels?

Here are a few ways banana peels can be harmful to your Hydrangea.

#1. You should never bury a fresh banana peel near your hydrangea.

A lot of information does talk about using wet banana peels to fertilize your hydrangeas, but it is not a good idea to use wet skins.

They will rot and attract various pests. There are also a lot of other disadvantages to using wet banana peels, and the benefits are very few.

Fresh plant debris starts to decompose. It will form colonies of bacteria and pathogens. This can lead to root rot, which can cause problems and is difficult to cure.

Also, the process of decay reduces the amount of nitrogen in the soil, which can affect the plants in the wrong way.

#2. Banana Peels can damage the roots of the plant.

Because of this, the plant can wither or even get sick through wounds if it is exposed to the decomposing remains of banana peels.

Another thing to remember is to never throw any leftover bananas or any other food around the hydrangea or any other plant. They will rot on the surface of the ground and attract various pests, as well as bacteria and fungi that can infect the plants and cause crown and root rot.

#3. Banana skins also contain some amount of saponins

Saponins can cause indigestion and vomiting upon ingestion. If you have any pets, they are at risk of being poisoned if they taste it.

#4. Avoid soaking a banana peel in water to make a liquid fertilizer.

This type of fertilizer is not efficient at all. Banana peels work much better as a dry fertilizer or as compost.

How to make compost from banana peels?

More beneficial than just leaving dry banana skins under the plant would be to make compost.

  1. Cut the banana peels with scissors into fine pieces that are not more than half an inch in size. You will get better results with smaller pieces.
  2. You will also need to add some green matter to the compost. The process of composting requires nitrogen. You can cut some green foliage from the plants and trees. The amount of this foliage should be about one-third of the total mass of compost.
  3. Along with banana peels and green foliage, you can also add other organic matter.
  4. Make sure your compost does not contain any animal-based matter like meat, fish or dairy products. This is because pests like mice and rats will invade the compost and take away all the nutrients that this matter provides.

You can use a composter to prepare your compost. There are a lot of different models in the market. You can do some research and get one that is more convenient for you.

There is also the option of a homemade composter that many people prefer. It can be made of boards; another way is to dig a shallow hole and put all the organic matter into it. This way is very easy and efficient.

During the process of composting, all the materials and layers of your compost should get access to air. This way, you will get compost that is sufficiently rotted.

If all the components are not getting enough air, it will result in the process of fermentation. Because of this, bacteria will form in the matter which can damage the hydrangeas even further.

Regularly check the humidity of the compost. It should be moist but not too wet.

If the humidity is not sufficient, the material will dry up without getting decomposed. If there is an excess of water, the bacteria that are supposed to turn the organic matter into fertilizer will die. The compost will also not become well-rotted.
