Step-by-step Guide to Grow Lettuce

Step 1:  Choose the planting season

It is best to plant lettuce during the spring and summer months. It should be planted when the temperature and soil are both warm.

Step 2:  Prepare the soil

For optimum growth, it is best to plant lettuce in rich, well-drained soil in a sunny location.  The soil should not be too moist or dry.  It should be kept moderately moist so that the roots are not stressed.

This is to help them grow quickly and develop into healthy plants.  When growing lettuce in the ground make sure the area is weed-free, has a good amount of organic matter, and any rocks and other hard objects in the soil are removed.

Step 3:   Planting the seeds

Seeds are best planted around 3/4 to 1” deep.  Make sure the seeds are planted evenly.  There should be at least two seeds per inch.

The seeds should be planted in a shallow hole. If the soil is too wet, the roots of the lettuce will rot.

Make sure that you don’t plant the seeds too deep because they will not germinate. Lettuce can be planted between two rows of other vegetables, such as beans or corn. This will help to keep the weeds out.

Step 4:   Watering

Water the soil and let it dry for several days.  Then water again, but make sure not to overwater.  If the soil is too wet, the lettuce will rot. 

Lettuce needs around one to two inches of water a week during the growing season. Once the plants have been watered and the seeds have germinated, the plants should be spaced approximately three inches apart.

Step 5:   Fertilizing

When the plants are about two weeks old, you should start fertilizing them.  Make sure that you fertilize your plants in the early spring before the soil is too cold. 

Use a nitrogen-rich fertilizer such as alfalfa meal, fish meal, balanced water-soluble fertilizer, granular fertilizer or composted manure. Make sure to apply it around the base of the plant, but don’t apply it too close to the stem or it will burn the plant.

Step 6:   Harvesting

You will know when to harvest the lettuce when it gets big and full of leaves.  Harvest your lettuce when the heads are full and this is in about 6 to 8 weeks.

You should wait until you see that the head has turned green before harvesting it.  You can then use the harvested leaves to make salads or add them to sandwiches.  You can also plant your lettuce seeds indoors, in seed trays.

This way, you will have a head of lettuce in the garden by early spring.  Make sure that the seedlings are not too big or else they may not survive.  You can also buy transplants from your local garden store.
