Seed Depth Reference

Quick reference list of how to bury, or not, different kinds of seeds:

Don't bury:  lettuce, allysum, thyme, anything thats seeds are as tiny as dust or flat as paper.  Water them in and protect them from birds.

Cover or not:  things that are the size of coarse ground pepper.  Things like: mustard, kale, basil, tomatoes, peppers, onions.  Tamping them gently will help them.  A thin layer of vermiculite will help, but isn't critical.

Cover with a thick layer of vermiculite: cilantro, chives, dill, parsley.  Anything that grows in a clump.

Cover with vermiculite and then cover with another tray: sage, microgreens.
