3. Banana peel tea.
The potassium is considered one of the most important nutrients for plants after nitrogen. This is involved in the photosynthesis process, in the osmoregulation of water in the plant and the formation of resistant tissues.
When plants burn easily, appear dull and reduce flowering, they may be deficient in this nutrient. To add a good amount, it is worth adding a little banana peel tea.
How to use.
- Cut the banana peels into small pieces and bring them to a boil in enough water for 15 minutes.

4. Wood ashes.
The wood ashes are rich in potassium and phosphorus; the latter helps in the ripening of the flowers and fruits, enhancing their aroma and flavor. However, by altering the pH of the soil, they are not recommended for acid soil species.
Before preparing it, it is important to verify that the ashes do not come from woods compromised with heavy metals or other contaminants.
How to use.
