"When my Aunt Ruth was alive, she loved to work in the vegetable garden--and my garden became hers. That was OK, because I never had to weed or water that garden and, most of the time, I could just stand there and enjoy watching her enjoy what she was doing. She loved to grow leaf lettuce because it grew so fast, tasted so good and because you could cut it down to a couple of inches of the ground and it came back without replanting. (I too share Aunt Ruth's love for leaf lettuce. It tastes fresh, grows so well and makes a lot of sense for us home gardeners!) She loved the different shapes, colors, textures and tastes of the foliage; most nights she would pick lettuce for us and make a wonderful salad. Her favorite was a salad of just mixed lettuce greens with basic oil and vinegar dressing. She would say to us, "I have made a honeymoon salad--lettuce alone." I do miss her a lot, and when I am in the vegetable garden working, I know she is right there next to me, working alongside me.

| Luscious Red Sails Leaf Lettuce--my favorite! |
Did you know that there are 4 main groups of lettuce that you can grow in your garden? The crispheads, loose heads, Cos or Romaine types, and leaf lettuce. The crispheads will form a solid and more rounded head of foliage--the 'Iceberg' is the most popular type found at the supermarket. This family is great for the spring and fall only, as it does not do well in the heat of summer. Cool weather is the key for this family of lettuce. It takes about 85 days to grow in the spring and 95 days in the fall for this family to mature, so plan ahead.
The loose head types--commonly known as the Bibb lettuce family--do not produce a firm central head. The foliage is loosely packed, more tender, much darker in color, and forms many outer leaves around the head. Some of these types of lettuce will tolerate the summer heat, but all will grow in the spring and fall.
Cos or Romaine types of lettuce will form upright growing heads with longer leaves and a thicker central midribs for support. This family will take longer to grow and mature, so plan ahead. The flavor is best when planted as a spring or fall crop in your garden. Summer heat will spoil the flavor and the plants will bolt easily in the hot weather, making them bitter tasting. (You can try growing the Romaine in the shade in the summer but I do agree with Paul for sure.)
Aunt Ruth's favorite was the loose leaf; this family does not make a head at all. It resembles an arrangement of beautifully arranged leaves growing from a central point with foliage of different sizes and colors. This family will mature very quickly--in just 40 days in the spring or fall. During the summer, it's even faster because all you have to do is cut it back to within 2 inches of the ground and in just a couple of weeks the plant will replace all the foliage you ate earlier in the season. This plant has the ability to re-grow new foliage 2 to 3 times a season, if you fertilize with a water solvable fertilizer every 2 weeks. Use Miracle-Gro or Blooming and Rooting for the best response. (I really recommend all natural Fish and Seaweed fertilizer for this purpose!)
All lettuce plants do best with cooler temperatures and you might think of planting some of your favorite varieties in the shade during the summer. To me lettuce can also be used in the landscape as a foliage plant grown for color. Much like what dusty miller, vinca vines, coleus, and sweet potato vines are grown for. Best of all, when lettuce is grown in containers you can eat the foliage as it matures as a bonus. Lettuce will also make a wonderful container plant for those of you with limited growing space--so consider growing mixed colored and foliage types of loose leaf lettuce instead of flowers in your container this summer. (My wife and I prefer leaf lettuce grown in containers. It is easy to cut and use immediately because it grows cleaner in a container--less soil from your garden finds its way onto the lettuce leaves.)
If you would like early lettuce for your garden, now is the time to start the seeds indoor to transplant seedlings into the garden during mid to late April. Use a seed-starting soil like Jiffy mix or the new Espoma Organic Soil with mycorrhizae bacteria added to it. When the plants are 1 to 2 inches tall, transplant them into the garden and space them according to the type recommendations. You can direct seed into the garden in late April, as soon as the ground has warmed up. If you're planting loose leaf lettuce types and want fresh lettuce all year long, plant 2 to 3 feet of new seed row every 2 weeks. This will give you fresh succulent plants developing all season long.
When you plan your garden, just remember to rotate your crops, as lettuce should be rotated every year to a new location, so as not to deplete the soil of nutrients that the crop needs to grow. I plant lettuce at the base of tall-growing plants like tomatoes, peppers, broccoli and Brussels sprouts (just for example) in the summer and use the shade they produce to cool the lettuce plants. The main thing to remember is that lettuce MUST have a lot of water during the hot days of summer or the plant will "bolt," which means it stops making leaves, and makes seed instead--and the foliage will get very bitter tasting.
Lettuce will grow in most soils and the better you prepare it, the faster the plant will mature--especially during the heat of summer. If you direct seed in the garden and seedlings come in thick in areas and spare in others thin thick area--just dig out a few seedling and transplant them. If plants are grown too close together, they will be less productive for you. Plant seed just about 1/4 inch deep and keep wet until they germinate; they will take about 10 to 14 days to germinate.
If you like variety in lettuce you can also purchase mixed blends of seed like Mesclun spicy mix, Mesclun Salad Mix, mixed color leaf types, and mixed texture leaf types. (We will have more types of lettuces and greens available this year than ever before!) I plant several of these mixes for variety, color, texture, and flavor. This spring, be sure to plant lettuce in your garden, your containers or as an accent plant in your landscaping. As my Aunt Ruth would say: "How about a honeymoon salad tonight--lettuce alone." Enjoy!"
Special thanks to Paul Parent! (Aunt Ruth sounds like she was quite the character!)
