Many people already have plant food at home without realizing it. Many people think that they can only buy plant food in the store as an end product. Yet there are many products that we use every day that also serve as food for plants (for both garden and house plants). Below an overview.
Boiling water from eggs as plant food
If you have boiled eggs, there is a lot of lime from the eggshells in the cooking water. Lime is a healthy food source for plants. After you boil eggs, let the water cool. Then water the plants with this boiling water. The plants will improve.
Tea residues as plant food
When your tea has cooled down, many people throw it away. However, tea contains many substances that serve as a good source of nutrition for your plants. Always give the tea that you have left to your plants.
