Many home gardeners prefer organic gardening. The biggest challenge that you face while growing tomato plants is providing enough organic fertilizer. We can use many kitchen wastes as a source of fertilizer for tomato plants. These toxin-free fertilizers are good for your health. In this article, I’m going to discuss banana peels good for tomato plants.

Tomato plants are heavy fertilizer feeders. These plants pass several growing stages throughout their life cycle. At each level, we have to provide the required fertilizer in a reasonable amount.

Tomato plant requires Nitrogen (N), Phosphorus (P), Potassium (K), Calcium (Ca), Magnesium (Mg), Sulfur (S), Chloride (Cl) in more significant amounts, and micronutrients like Iron (Fe), Boron (B), Manganese (Mn), Copper (Cu), Molybdenum (Mo), Zinc (Zn) in smaller amounts. (source)

Are Banana Peels Good For Tomato Plants?

Banana peels for tomato plants are a good source of organic fertilizer. These peels are rich in Phosphorus (P), Potassium (K), Magnesium (Mg), and Calcium (Ca). Tomato nutrient deficiency highly affects its fruit development and leaf growth. This lack of soil fertility will result in losing fruits, and growth stunts discoloring the leaves.

Calcium, magnesium, and potassium deficiencies result in blossom end rot, tomato leaves curling inwards, losing green color through veins, and yellowing leaves.

Therefore it is highly beneficial to use banana peels directly into the soil (like a tea or powder) or add them to your organic compost bin.

Banana peels powder for Tomato Plants.

In this method, we dry the peels and crush them into the smallest pieces possible. We must first remove the water from these banana peels because they are very juicy.

For the dehydration process, we can do it mainly in two ways. Dry them either in bright sun or oven. The process of drying in the sun takes some time. But it is a simple, inexpensive method.

Electric or gas-based oven is faster, and you can dry them in less than 30 minutes depending on the maximum temperature. In my situation, I used a Microwave oven at the temperature level 570°F (300°C). (Do not use the microwave option. In my case, dried peels start making a small fire inside the oven. Always use the conventional option in the microwave oven).

First, prepare the peals. For this, you can use a grill rack. Lay down the leaves one by one. If you have a large number of leaves, you can use a multi-level frame for this.

Fill the water up to an inch above the level of peels. That level is enough to dissolve nutrients.

Every 2 to 3 days, mix this tea well.

After 6 or 7 days left, this banana peels tea is ready to use. We can directly pour them into the soil or mix them with the water. I recommend mixing the banana peels tea with water in a 1:5 ratio.
