For all of your gardens, I couldn't recommend a product more highly:
https://www.liquidirt.com/
Up here in Sand County, our soil is horribly poor...I bought a couple bottles of this stuff at a gun show a few years back to see if this would help...It was in liquid form then...But its organic ingredients started to ferment and the bottles started leaking....I put one of them in mom's flower bed in the middle of the yard...Last year the peonies formed three buds when they had only ever had two...This year she got a total of seven (eight with the pink one) and the irises that she thought would have to be given up on exploded.
And the Liqui-Dirt makes WAY more than the one gallon is says in the instructions...More like 5 gallons.
I sprinkled a modest amount near the new lady slipper shoots we have in the woods...We'll see what happens in the next couple of years.
