To make this type of organic fertilizer, you need black tea (or tea grounds).
I use 3 teaspoons of black tea.
Add 1 liter of boiling water.
Incubate until the water cools.
Once cool, strain to remove sediment.
Add water to obtain 5 liters of black tea solution.
Then, add 1 teaspoon of baking soda.

METHOD 1:

1. Water the roots of the orchid with this fertilizer solution.
2. Black tea contains many minerals and organic substances that provide nutrition to orchids.
3. It contains nitrogen, potassium and phosphorus, which are essential nutrients for orchid growth.
4. Baking soda can increase the pH level in the orchid pot, which is useful for reducing acidity if you use a lot of chemical fertilizers.
5. Baking soda also has the ability to eliminate insects and fungi that are harmful to plants.

METHOD 2:

1. Spray this fertilizer all over the orchid.
2. This method is similar to using foliar fertilizers.
3. You can use it as a natural pesticide to protect orchids from insects and diseases.

METHOD 3:

1. Clean the surface of the leaves with this fertilizer solution.
2. The surface of the leaves will always remain clean and the stomata will not get clogged.
3. Orchids will photosynthesize better.

RESULTS:

1. The roots of the plants will be protected and enriched with nutrients, so they will grow very healthy.
2. The orchids will absorb more nutrients, helping the flowers to bloom beautifully.
3. The flowers will remain on the branches for a long time before withering.
