Red leaf, radicchio, romaine, and more. With such an abundance of delicious and nutritiouslettuce varieties available, it can be challenging to choose just one to grow in your garden. The good news is thatcultivating lettuce is almost as simple as sprinkling seeds (one of the reasons they are simply the perfect succession plant) so you can try and taste a new type of lettuce almost any time you like!
From simple spinach to elegant endives, Pinetree Garden Seeds sells a wide variety oforganic, heirloom, non-GMO lettuce seeds and we are here to share with you all we know abouthow to grow lettuce at home.
Before you beginplanting lettuce seeds, watch the weather. Lettuce grows best and is less likely to bolt (or shift from making leaves to making flowers) in the cooler months of late spring and early autumn. Mostlettuce varieties prefer soil temperatures between 50 and 70 degrees and are not likely to sprout in the sweltering heat of summer in most growing zones.
If your sunny beds are baking your buttercrunch, schedule some shade with taller companion crops. Arrange sunflowers, pole beans, and tomatoes to supply shade during the hottest part of the day (but not to take the sun away entirely) and your bibb will no longer bolt too soon. Layers of straw and mulch also keep soil cool while helping to maintain moisture.
Lettuce may be a cool-weather crop, but that doesn't mean it likes cold soil. Here in Maine, we give our seeds a head start by growing them indoors where we can better control their climate. When it is time to transplant—or when it is clear that your seedlings are taking over the pot you planted them in—take care to disturb the roots as little as possible on the way to their new home.
And remember how lettuce doesn’t like cold soil? It also doesn’t thrive in poor soil or in crowded conditions. Space your plantings appropriately, no matter how spindly they seem at first. Make sure your soil is moist, rich, and crumbly to the touch. The taste of lettuce will tell you if you got it right—lettuce leaves tend to toughen and taste bitter if the growing conditions aren’t at their best.
It all depends on what you would like to harvest! Based on the temperature of your soil,lettuce germination can take place in 7-10 days and most lettuces mature in 45-55 days. A few varieties (like romaine) take a bit longer to reach their full size but that doesn’t mean you have to wait!
Remember the younger the plant, the more tender the leaves. So if you are craving crunch all year,grow leaf lettuce in small, staggered amounts as often as you can. Each harvest will make space for another succession of plants—and make the most of your growing season.
Harvested less than a month after germination when they are approximately two inches tall, microgreens are quick to grow and packed with nutrients. Think of them as adolescent lettuce. Salad greens, leafy vegetables like cabbage or broccoli, and even herbs can all be cultivated in containers and cut when they are still small. Start withorganic lettuce seeds and you’ll begrowing microgreens that are good for you and your garden.
Younger than microgreens (and eaten from root to shoot)lettuce sprouts grow quickly in the smallest of spaces without much light and are a favorite option for windowsills. Once your tiny greens have been harvested you can start a new crop in the same soil. Growing sprouts and microgreens also makes it easy to experiment. Beet leaves too bitter? Try eating them at a different developmental stage to find the flavor you like best.
