How long do lettuce plants last?
Similarly one may ask, how do you harvest lettuce so it keeps growing?
Cut the outer lettuce leaves about 1 inch above the crown. This protects the crown so the lettuce can continue growing. Cut off the amount of lettuce needed when the leaves reach a length between 3 and 6 inches. Water the lettuce regularly to encourage continued growth even after you begin harvesting.
Furthermore, can you grow lettuce all year round? Lettuce. Choose the right varieties and you can have lettuce almost all year round. You can also grow a variety of salad leaves that can be picked while young and tender.
Likewise, people ask, what is the lifespan of lettuce?
Will lettuce regrow after cutting?
Head lettuce will die back, but most leaf-lettuce plants renew efforts to produce leaves, if regularly watered after trimming. Results will often be smaller than the original plant, but you may be able to harvest a second, good-tasting crop within as little as two weeks.
