recycle plants

anyway i can add old plant leafs into some soil after drying them

to make some sort of fert

It takes a while but you can compost them along with your grass clippings, banana peels, melon rinds, anything else that would normally be thrown into the typical compost pile. My first few grows I used compost from my yard which contained years of grass clippings and leaves and old rotted veggies and such. Only for my last two grows have I bought any soil, FFHF, and the compost grows were far bigger, healthier, and more vigorous than the "super soil" I paid for. Yes you can compost, not sure how effective trimmings would be by itself or in a short term compost-type fertilizer, but if you already have a compost bin or pile, add that stuff. It surely can't hurt anything as, except for nutes, it's all natural and will break down like anything else, in time. You can try grinding it super fine, but it will still just be dead plant matter in your soil until it breaks down properly, allowing beneficial bacteria and microbes to form.

If you dry them out and add it to the soil it won't do anything its dried out all the nutes that may of been in the leaves should of left with the moisture, your better off using wet leaves if any but you would need a lot is leaves to get any useable amount is nutes or have it work as a fert.

kk thanks just checking +rep
