Hi folks,

I'm preparing raised beds for dahlias this year, and was wondering if I should mix in some slow-release organic fertilizer into the potting soil (which will have some basic compost mixed in) then or if i should wait to feed the plants once they're sprouted. I've read to wait, but I was wondering about this since the potting soil will have virtually nothing in it in terms of n-p-k (the compost will have some, I realize).

Your advice is appreciated!

Cheers,

TRB
