I'm talkin'... forget the fertilizer, and the mulch, and the raised beds..... Use what nature has already provided right there.
A couple weeks ago I wanted to plant some pea seeds. I read they prefer to be planted after the ground has thawed, but still cool. I looked around the gardened area, and spotted some nature-made mulch of dried leaves that were stuck together and piled heavily on the dirt from the fall and winter, and sure enough, when I pushed them aside, the soil was still very cool. So I put some pea seeds under there, and several other spots like that. Anyway, I have pea sproutings!
Excited to see how this turns out.
