Other Plants That May Benefit From Banana Peel Flour
Potassium is especially valuable for plants that flower heavily or produce fruit. Banana peel flour can be a helpful supplement for:
1. Tomatoes
Tomatoes use potassium for fruit development and overall vigor. A small amount mixed into soil can support fruiting-especially if your base fertility is already decent.
Use lightly at transplant time and again when flowering begins.
2. Peppers
Peppers respond well to balanced feeding with sufficient potassium during flowering and fruit set. Banana peel flour can complement compost and a balanced fertilizer.
3. Eggplant
Similar to peppers: heavy fruiting benefits from potassium support and strong root health.
4. Cucumbers and squash (sparingly)
These are heavy feeders. Banana peel flour can help as a supplement, but they usually need more complete nutrition.
5. Strawberries
Potassium can support flowering and fruit quality. Use small amounts worked into soil around plants in early spring.
6. Flowering annuals and perennials
Plants that bloom repeatedly may benefit modestly, including:
- zinnias
- marigolds
- dahlias
- geraniums
- petunias
Use minimal amounts because many container flowers are already regularly fed with liquid fertilizer.
7. Houseplants (with caution)
For indoor pots, banana peel flour can attract fungus gnats if overused. If you try it:
- use a tiny pinch mixed into the topsoil
- keep the pot on the dry side
- consider compost instead for safer indoor use
