I kill everything, so yes I have failed to grow the "easy for beginner" plants quite a lot. I seem to be in a weird part of the country where it's too hot for some things and not cold
enough for others, or maybe I am just not a gardener and I'm making excuses. I finally just started sowing random seeds to see what would fare well on it's own. So far carrots and mustard greens are growing pretty well. Mustard greens seem to be slow growing but the carrots are doing great. I've actually been spending most of my time in the garden thinning them.
We also accidentally sprouted a bag of the '15 bean soup' mixes, found some flour bugs and didn't want to use the bag, let them soak a couple days and before we got a chance to give them to the
chickens, they all sprouted so we decided to toss them out in the garden. We got some heavy rains that uprooted most of them and then some hard frost that killed a bunch but there are a handful that must have gotten a hold of the soil and they are starting to grow. Put a couple in potters in our kitchen window and one has grown about 2 ft in about two weeks. In a month or so when most of the cold weather is over, we are going to sprout another bag and plant those as well.
So I guess my strategy is to just start planting stuff and as I have successes, I will take note and fine tune what I do for next time. I was getting so wrapped up in when to plant what where, how to fertilize, etc and never got anywhere with it. So now I'm just winging it and seeing what works. Eventually I'll know what I'm doing
