Would green tea and coffee grounds be compatible with coco coir as a natural plant nutrient/fertilizer? I've read about making liquid fertilizers from green tea, but I thought I'd try adding dry leaves to my coco coir substrate to help stimulate growth. The coffee grounds should work well enough for adding nitrogen, and I would think the green tea would offer enough of the other needed nutrients to get them off to a good start. The diet will likely change when it comes time to transplant, but I'm hoping this will work well for the new sprouts. Decaf coffee and regular green tea is what I have in mind.
I'm growing peach tree's from seed and intend to plant the seedlings in this type of substrate mix.
I used to compost table scraps with a little worm farm. I would add coffee grounds, tea leaves, about 50% paper from a paper shredder; dry ingredient, old vegetables, banana peels, egg shells, old pasta, and all forms of veggie kitchen scraps; but not meat, to my little worm farm and then allow the worms to eat and compose. There is no smell.
You use their droppings, called worm castings, as black gold bioactive fertilizer. The little spout at the bottom allows you to get a liquid version of this fertilizer from excess water that come from the scraps after they are processed You can add old fruits but that tends to attract fruit flies, which is not a big deal if you are outside. Meat products can be used by that attract flies. Just add some red worms and they multiply, feed, and poop gold.
As a level of the worm farm gets filled with scraps, you add another level. The worms wiggle through the holes between levels and eat upwards. Their droppings/fertilizer not only have diverse nutrient and mineral for plants but the bacteria in their poop, makes the soil bioactive, which helps to break down organic materials already in the soil, making it easier for the plants to digest. One add some compose and extra worms to flower pots and have a live bio-active feeding station for each tree. You can even recycle the tree leaves for worm food.
