Last minute soil ammendment
I'm moving into a new place mid January and there's already a small patch in the back yard where the previous occupants had a garden.
Most of what I'll be growing will be in containers but I am wanting to do watermelon from seed in that small patch in Feb (so about a month after I move in).
Eventually I'll do a soil test and find out exactly what needs to be added but I'm wondering what I can get away with adding in the mean time so I can at least start the watermelon?
If I can find some decent bulk compost for a good price I was thinking just digging that in with some organic granulated fertilizer...
If I can't find any the only thing I can think of is Lowes sells some "50/50 manure/compost" mix that says it's 0.5-0.5-0.5 and mixing that in with the fert. I always question the quality of that kind of stuff from big box stores but I'm not sure what else to use.
Unfortunately, I don't know what if anything the previous occupants added but here in FL it's usually very sandy with low OM. So far my search for a truck load of compost hasn't yielded much. Any ideas?
