Soon after beds were built, they were planted with warm season annuals. For those of you just becoming familiar with veggies and their growth 'habits', tomatoes and peppers are two of the key crops for a warm season or summer garden. These two varieties, in addition to squash, corn and sunflowers, need heat to do their thing. Some varieties like beans, peas and spinach grow well in the in-between temps: 80-90 degrees. But most summer varieties will want continuous days in the high 80s or hotter to really flourish.
The most important discovery regarding this summer experiment was that warm weather vegetables have an absolute requirement for more root space than the one cinder block provides. The plants just don't grow well if there isn't enough depth. Good drainage and enough space are critical for healthy plants, and the yellow seen in young plants indicates too much water/not enough drainage around the roots.
