These are pictures of two different squash plants that I planted from seed the same day. The top one is the first bed I built, full of Home Depot topsoil and compost. The bottom photo is one of the beds filled with supposedly 50-50 amended topsoil. Except all the vegetables in that new soil are small and sickly. The veggies in the old soil are huge.
This weekend I amended one of the beds with compost, and spread a layer of compost in the other beds where I didn't want to rip out had had grown to this point. I'll post a photo of the runt from above later if it all works out.
