Using Used Coffee Grounds

Hi there. I got this used coffee grounds from Starbucks and used it on my Ashitaba, Chili, and Coleus. I noticed some web-like thing with small yellowgreen dots. Should I cover the grounds with soil/medium or should I dig and throw them away?

Re: Using Used Coffee Grounds

UCG are nutritious and mold will grow in them if left in a thick layer or clump exposed on top of the soil. They can also dry out and shed/repel water. Most people agree its better to scratch/rake them into the soil or cover with mulch. Don't worry if there are mold already growing.

DON'T THROW IT AWAY :shock: ..... :wink:

I meant to throw the top grounds lol. Anyway, I will just let the mold grow, perhaps cover the top with coco peat :) thanks!

Stir it into dirt. One finger will do the trick.

Re: Using Used Coffee Grounds

Coffee grounds can go into the compost too.

Make sure the coffee grounds are spread out and not in a heap.
Happy gardening in Hawaii. Gardens are where people grow.

Re: Using Used Coffee Grounds

Ok, noticed this just now. Last Saturday, I mixed some of the coco peat with ucg which I dried for a week. I used the mixture to put the transplanted basil and a couple of chilis (they are all more than 6 inches tall). I left them out in the shade with 2 hours of light just to get them used to the new soil, and watered them just once. When I checked out today, the top budding leaves have yellowish color from the stem up to the middle leaf. Could this be too much N or I still need to put them in minimal light for another day?
