This is probably a stupid question, but I'm just starting to experiment with
growing from seeds. All the seed packets I have provide specific depths to
plant the seeds under the soil, so I assume I shouldn't mulch over them if I
plant directly in the ground (as opposed to containers or flats). I do want
to mulch around the plants eventually, so when is the most appropriate time
to do that? Does it depend upon how tall the seedlings are, what type of
plant, etc.? For example, I just planted sunflowers, zinnias and cosmos.
All three of the packets say to thin and separate when the seedlings stand
about 2 inches tall. Would it be OK to mulch at that point, or should I
wait until they get taller? Thanks in advance for any assistance.
