Quick Guide to Growing Lettuce

Lettuce is a cool-weather crop, ideal for planting in early spring or fall when temperatures are mild and the days are shorter. It thrives in temperatures between 60-70°F (15-21°C), making it perfect for these transitional seasons. With various types from leaf, romaine, butterhead, to crisphead, lettuce can diversify your garden, providing both aesthetic appeal and culinary versatility.

Start your lettuce from seeds for best results, as transplanting can sometimes shock the plant. Sow seeds directly into the ground or containers, spacing them to allow airflow and prevent overcrowding. This encourages healthier growth and reduces the risk of disease.

Soil, Planting, and Care

Lettuce prefers well-draining, nutrient-rich soil. Enhance your soil by incorporating organic matter such as compost. Lettuce enjoys a slightly acidic to neutral pH level between 6.0 and 7.0. Regular soil testing can help maintain optimal growing conditions, making pH adjustments as needed with lime or sulfur.

Water your lettuce regularly, keeping the soil consistently moist but not waterlogged. Lettuce has shallow roots, so smaller, more frequent watering is typically better than deep soaks. Mulching around the base can help retain moisture and keep weeds at bay.

Troubleshooting

Is leaf-type lettuce easier to grow than the head-type?

Leaf-type lettuce, such as looseleaf and butterhead, is generally simpler to cultivate than head varieties like crisphead. Leaf lettuce matures quicker and is less sensitive to bolting, making it a favorable choice for beginners or those in warmer climates where temperatures fluctuate.

The tips of my lettuce leaves are turning brown, but the base looks healthy. What is the problem?

Browning leaf tips often indicate inconsistent watering or a nutrient deficiency, typically calcium. Ensure your lettuce is receiving sufficient and regular water, especially during dry spells. Consider a calcium-rich foliar spray to address potential deficiencies.

My lettuce plants have grown tall and flowered. What should I do?

When lettuce bolts, it means it has started flowering and is focusing on seed production. This usually happens when temperatures rise. Once this process begins, lettuce tends to taste bitter and the leaves become tougher. If bolting starts, it’s best to harvest the leaves quickly and plan for a late-season planting when conditions cool.

My lettuce tastes bitter. Is it the variety?

Bitterness in lettuce can arise from heat stress or infrequent watering. Some varieties are naturally more bitter than others, but this often intensifies with heat. Shading your plants in hotter weather and maintaining consistent moisture will help manage the bitterness.

Harvest and Storage

Harvest your lettuce when the outer leaves are large enough to eat, around 3-4 inches long. For head lettuces, wait until the heads are firm and compact. It’s best to harvest in the morning when the leaves are crispest.

After harvesting, rinse the leaves thoroughly to remove dirt and pests. To store, pat them dry and place in a loose plastic bag with a paper towel in the refrigerator crisper. Proper storage can extend lettuce freshness for about a week.

FAQs

Quick answers to common lettuce questions:

• 
  Can I grow lettuce indoors?
