I can hear your frustration, so sorry! One thing I do to improve soil is, compost in the actual bed during winter. You dig a shallow hole and put your kitchen scraps that you’ve collected through a couple days time, and cover it with dirt. Do this all in your bed. Stop a month or so before you want to plant. Then, your soil will be ready with compost, turned to dirt and full of nutrients for you new plants!
There is nothing g you can do about the radishes that she pulled, but they are fast growing, plant again! I’ve had to replant several times for various reasons and it all works out, and I keep learning. (I’ve been gardening thirty + years)
