Hopefully by now your early efforts to have enough crops to yield plenty for your family. I enjoyed reading of your various plants, seeds, and trees, and hope they are producing well by no.
On the rhubarb site, I recall that it does well on old seasoned manure piles, or along the grape vines in semi sunny areas at the various places I have lived over the years. I hope yours is doing well enough for you to enjoy a rhubarb custard pie, like my late mother made…one of my favorites !
I hope too that you have planted both peach and plum trees …to help both pollinate the other…as well as a sour cherry tree, which makes a delicious pie too ! Peach pie flavored with almond extract is best !
Best to plant your blackberry bushes in a separate area, in rows and prune them back yearly or they will overtake the area.
Mint of any kind does spread easily but is helpful in keeping the groundhogs away and lessens the flea population as well. I grow it near my doorways and it’s fragrant and blooms are pretty as well.
White clover is a good choice for low maintenance pseudo grass, and will help with soil and pollination, chocking out weeds.
Sunflowers are easy to grow and might provide a nice distraction for some sunny areas.
Echinacea is another good option too.
You sound much like me, forty years ago…I’m retired and only garden vicariously now !
I hope you are doing well with your Food Freedom Homesteading !
Best wishes !
