How to harvest lettuce from Aerogarden

Aerogarden systems have gained popularity as a convenient and efficient way to grow fresh herbs and vegetables indoors, including lettuce. Harvesting lettuce from your Aerogarden is a satisfying process, as you can enjoy the taste of homegrown greens right at your fingertips. In this guide, we will walk you through the steps to successfully harvest lettuce from your Aerogarden.

Choosing the Right Time to Harvest

Before you begin the harvesting process, it’s crucial to identify the ideal time for picking your lettuce. The optimal time to harvest lettuce from your Aerogarden largely depends on the lettuce variety you’re growing, but there are some general guidelines to follow:

  1. Size: Lettuce leaves are typically ready for harvest when they reach a size of 3 to 6 inches in length. At this stage, the leaves are tender and full of flavor.
  2. Appearance: Look for vibrant, healthy leaves without any visible signs of wilting, yellowing, or damage. Avoid harvesting leaves with brown spots or discoloration.
  3. Growth Stage: Harvesting lettuce early in its growth stage, when the leaves are still young and tender, will yield the best flavor and texture.
  4. Continuous Harvest: Aerogarden lettuce varieties are often “cut and come again,” meaning you can harvest individual leaves while allowing the plant to continue growing. This approach extends your harvest and ensures a constant supply of fresh lettuce.

Steps to Harvest Lettuce from Your Aerogarden


Now that you know when to harvest your lettuce, let’s go through the step-by-step process of harvesting it from your Aerogarden.

  1. Gather Your Supplies:
  • Clean kitchen shears or scissors
  • A clean container or basket for collecting the harvested lettuce
  • Latex or gardening gloves (optional)

2. Wash Your Hands: Before you start, wash your hands thoroughly to ensure the lettuce remains clean and uncontaminated.

3. Inspect the Lettuce: Carefully examine the lettuce plants in your Aerogarden to identify leaves that are ready for harvest. Look for leaves that meet the criteria mentioned earlier: the right size, vibrant appearance, and young growth stage.

4. Choose the Leaves: Select the leaves you want to harvest. For “cut and come again” varieties, it’s typically best to harvest the outer leaves, leaving the inner ones to continue growing. If you’re growing head lettuce, you can harvest the entire head at once.

5. Cut the Leaves: Use clean kitchen shears or scissors to snip the selected leaves. Make clean cuts near the base of the leaves, taking care not to damage the surrounding foliage. Avoid tearing or pulling the leaves, as this can harm the plant.

6. Collect the Harvest: Place the harvested leaves in your clean container or basket. Be gentle when handling the lettuce to prevent bruising or wilting.

7. Rinse and Dry (Optional): While harvesting lettuce from your Aerogarden, you may notice some water droplets on the leaves. If you prefer, you can rinse the leaves gently with cool, running water and then pat them dry with a clean cloth or paper towel. This step is optional, but it can help remove any lingering debris.

8. Store Your Harvest: Once you’ve harvested the desired amount of lettuce, store it in the refrigerator to keep it fresh. Use airtight containers or plastic bags to prevent moisture loss and maintain the crispness of the leaves. Properly stored, harvested lettuce can stay fresh for up to a week.

Tips for Successful Lettuce Harvesting

  1. Regular Harvesting: To encourage continuous growth and a longer harvest period, regularly pick mature leaves while leaving the central portion of the plant intact. This approach allows the plant to continue producing new leaves.
  2. Avoid Overcrowding: As your lettuce plants grow, ensure they have enough space to thrive. Overcrowding can lead to competition for light and nutrients, resulting in smaller and less flavorful leaves.
  3. Observe Pruning Techniques: For head lettuce varieties, you can choose to harvest the entire head or practice pruning. Pruning involves selectively removing the outer leaves while leaving the inner ones to develop a new head.
  4. Monitor for Bolting: Bolting occurs when lettuce plants send up a flower stalk, resulting in bitter and less desirable leaves. To prevent bolting, keep your Aerogarden at an appropriate temperature (usually between 60-70°F) and maintain consistent light levels.


Harvesting lettuce from your Aerogarden is a straightforward and rewarding process, allowing you to enjoy fresh and delicious greens whenever you desire. By choosing the right time to harvest, using clean tools, and practicing gentle handling techniques, you can ensure that your lettuce remains crisp, flavorful, and perfect for salads, sandwiches, and other culinary delights.

Remember that the “cut and come again” nature of many Aerogarden lettuce varieties means you can enjoy a continuous supply of fresh leaves without depleting the plant. With proper care and regular harvesting, your Aerogarden can provide you with an abundant and ongoing source of homegrown lettuce throughout the year, regardless of the weather or season outside.
