NW, We’ve had warmer weather this Spring. So, I’ve cut a few asparagus stalks, parsley over wintered and so did a kale.
Last Fall our garden club had a speaker on seed saving. She brought in a “Moon and Star Watermelon,” and we all took some of the seeds and tried to save them for this year. Found them in the bottom of my basket and put them in pots...up they came...what do you know I did it right. I don’t really expect watermelons to ripen at my altitude and temperature. But, I’ll give it the gardener’s try.
If you can put down black plastic and cut a slit in that where you want to plant the melon seedling, that'll help to warm the soil. Melons like WARM soil and LOTS of water, so don't be stingy! I've never fertilized melons with anything other than compost.
