Our first heat wave of the season settled in after a few cool, rainy days beginning this week with temps. in the greenhouses in the low 90s. Fans, shade cloth, and roll up sides to greenhouse keep it relatively cooler than the possible 120-130 degrees. Often salad just goes dormant when soil temps get above 85 degrees. Luckily, lettuce in the outdoor beds is picking up after a slow start. After nearly 20 yrs. of growing experience, I'm beginning to figure out what types of greens do best in particular circumstances in the summer green house. Chard, beet greens, sorrel, edible chrysanthemum, anise hyssop, wild arugula, cutting celery, and now pea shoots with outdoor lettuces makeup the backbone of the warm season blend. Our tomatoes of semi-tropical origins of coarse love this heat and are growing rapidly to the first support wire.
