A Guide to Growing
Lettuce, Kale, and Arugula

As daylight extends and temperatures rise, the anticipation builds among those who eagerly await the arrival of early spring’s lush leafy greens.

From the crisp crunch of lettuce to the robust flavors of kale and arugula, early spring greens are a versatile addition to any garden and kitchen.

These vibrant and nutrient-packed vegetables not only add a burst of color to your plate but also offer a variety of benefits.

In this guide, we’ll provide a 5-step process on how to grow lettuce, kale, and arugula and explore the benefits of these delicious plants.

Growing Leafy Greens

Step 1
Choose Your Varieties

Take some time to explore the many varieties of early spring leafy greens available before you dive into planting.

Lettuce comes in a range of types, including crisphead, butterhead, romaine, and loose-leaf, each offering unique flavors and textures.

Kale, with its curly or flat leaves, presents options such as red Russian, Lacinato (also known as dinosaur kale), and the more traditional curly leaf kale.

Arugula is known for its peppery taste and adds a zesty kick to salads and dishes.

Step 2
Prepare Your Space

Begin by selecting a partially shady location in your garden and clear the area of any debris and weeds.

Choosing an area with full sun will cause your leafy greens edges to burn and their centers to bolt which will lessen your yield by causing premature flowering and seeding.

Loosen the soil to a depth of about 6-8 inches, breaking up any clumps and ensuring good aeration.

Early spring leafy greens thrive in well-drained, nutrient-rich soil.

Incorporate organic matter such as compost or aged manure to improve soil structure and fertility.

Aim for a slightly acidic to neutral pH level, ideally between 6.0 and 7.0, to optimize nutrient uptake.

We make our own compost from kitchen food scraps and other green and brown materials we find in our food forest.

Step 3
Planting

Once your soil is prepared, it’s time to sow your seeds or transplant seedlings.

For lettuce, scatter seeds thinly and cover them with a light layer of soil, as they require sunlight to germinate.

Indoor seed starters can be transplanted in early spring and ensure rows are spaced about 12-18 inches apart to allow for proper air circulation and growth.

Kale and arugula can be directly seeded or transplanted, with seeds spaced 6-12 inches apart.

Ensure consistent moisture during germination and early stage growth by watering gently or using a misting system.

Step 4
Care & Maintenance

Proper care is essential for the health and vigor of your early spring leafy greens.

Water consistently, aiming to keep the soil evenly moist but not waterlogged.

Mulching around plants helps retain moisture, suppress weeds, and regulate soil temperature.

Monitor for pests such as aphids, slugs, and caterpillars, and address any issues promptly using organic methods if possible.

Regularly inspect your plants for signs of disease, such as fungal infections or leaf discoloration, and take appropriate action.

Step 5
Enjoy the Harvest

As your early spring leafy greens mature, it’s time to reap the rewards of your efforts and you can enjoy your freshly harvested greens in salads, sandwiches, smoothies, stir-fries, or simply as a nutritious snack.

Tips for Harvesting
Leafy Greens

See some of our tips for harvesting leafy greens below:

Lettuce can be harvested by snipping off outer leaves as needed, allowing the inner leaves to continue growing.

Kale leaves can be harvested individually or by cutting the entire plant about 2 inches above the soil line, encouraging regrowth.

Arugula leaves are best harvested when young and tender, before they become too pungent.
