Thanks to Tanya who shared this link with me. http://homeguides.sfgate.com/trim-lettuce-regrow-71305.html Harvesting lettuce for maximum yield. As we have rushed from cold rain and partial sun to dry sunny and 78 degrees the lettuce is adjusting too. When the main stalk begins to elongate it is bolting or entering flowerIng state. We see this with kale, other greens and radishes. Don’t forget to water mulch and fertilIze. Liquid fish fertilizer is in the shed.
