SALAD GREENS ARE GOOD COMMUNICATORS — they “bolt” towards the sky and send forth a flower stalk when their time is over. Consequently, if you want a lengthy season of greens (including spinach, pictured up top), you have to make successive sowings throughout the summer months:
To reduce the stress of summer heat, which hastens bolting, re-sow plants where some shade is possible. In my own kitchen garden, I take advantage of the open patch beneath my tee-pee tomato trellis. As the tomato vines grow, they filter the light that reaches the newly planted romaine, escarole, frissee and spinach. You might have tall growers like broccoli, Brussels Sprouts or kale that you can plant your greens between or behind.
Or, make plantings in boxes or small tubs that can be easily moved to shady quarters. A friend grows all kinds of salad mixtures in plastic window boxes that she keeps beneath her covered back porch. The boxes are set on a 4-foot tall bench, out of the reach of rabbits who would otherwise devour the produce.
In any event, please re-sow your bitter-tasting, bolted greens. Having a fresh, continuous supply of salad in your garden will reduce the gas and oil you consume by driving several times a week to the supermarket.
