I hoed up a good chunk of the back troughs...enough to get blisters on my hands anyway. Then I mixed in the good dirt with the old-sandy-already-there dirt. It looked much healthier!
I stuck some poles in the dirt for peas and morning glories to grow on.
And I planted some flower seeds and onion sets. I'm still waiting for it to get warm enough to move my tomatoes outside, and plant beans and peppers.
