Step-by-Step Guide: Growing Lettuce from Seed to Harvest

Written by Emily Belkoff

Growing lettuce has been my go-to veggie for years. There’s something magical about watching those tiny seeds transform into crisp, flavorful leaves right in my backyard.

If you’re ready to join the homegrown lettuce club, I’m here to guide you through every step of the journey!

Lettuce Varieties

Before we dig in, let’s explore the world of lettuce varieties. Trust me, there’s so much more than just iceberg out there!

Cos/Romaine

  • Long, spoon-shaped leaves
  • Heat-tolerant and nutritious
  • Example: Paris Island Cos

I love growing romaine for its versatility. The crisp hearts make an excellent Caesar salad, while the outer leaves are perfect for wraps.

Loose Leaf

  • Frilly, crinkly leaves
  • Various colors available
  • Example: Black Seeded Simpson

Loose leaf lettuce is my go-to for quick harvests. The vibrant colors brighten up any salad bowl!

Iceberg/Crisp Head

  • Crunchy texture
  • Less nutrient-dense
  • Example: Ice Queen

While not the most exciting variety, iceberg still has its place. I grow it when I’m craving that classic wedge salad.

Butter Head

  • High in nutrients and minerals
  • Prefers cooler temperatures and rich soil
  • Example: Little Gem

Butter head lettuce is my secret weapon for impressing dinner guests. Those tender, buttery leaves are simply irresistible.

Other Varieties

  • Celtuce (grown for stem)
  • Mesclun mix

Don’t be afraid to experiment! I love trying new varieties each season to keep things interesting.

Planting Lettuce from Seed

Seed Starting Methods

  • Direct sowing (1/4 to 1/2 inch deep)
  • Using transplant trays

I prefer starting in trays for better control, especially when I’m juggling multiple varieties.

Seed Starting Process

  • Labeling importance
  • Creating depressions in soil
  • Sowing 2-3 seeds per cell
  • Optimal soil temperature (below 80°F)

Trust me, labeling is crucial! I’ve mixed up varieties before, and it’s no fun trying to guess what’s what.

Seedling Care

  • Thinning process (8-10 days after planting)
  • Identifying strongest seedlings
  • Option to keep multiple seedlings for baby lettuce

Don’t be afraid to thin your seedlings. It feels harsh, but it’ll give you stronger plants in the long run.

Transplanting Lettuce Seedlings

Timing and Preparation

  • Transplant after about 1 month
  • Selecting an appropriate planting site

I like to transplant on a cloudy day to minimize stress on the seedlings.

Understanding Lettuce Growing Requirements

  • Temperature preferences (up to 80°F max)
  • Water needs
  • Partial shade considerations

Lettuce can be a bit fussy about heat. I’ve learned to provide some afternoon shade during the hottest months.

Transplanting Process

  • Spacing (4-6 inches apart for full heads)
  • Handling multiple seedlings per cell
  • Fertilizing options (high nitrogen)
  • Planting depth and soil firming

I always give my seedlings a little pep talk as I plant them. It might sound silly, but I swear it helps them settle in!

Post-Transplant Care

  • Watering in the transplants
  • Mulching options and benefits

A layer of straw mulch helps keep the soil cool and moist – just how lettuce likes it.

Ongoing Care and Maintenance

Monitoring Plant Health

  • Checking leaf color and vigor
  • Performing the “tug test”

I make it a habit to check on my lettuce every morning. It’s a peaceful way to start the day and catch any issues early.

Watering and Temperature Management

  • Consistent moisture
  • Using mulch for temperature regulation

Lettuce loves consistent moisture. I use drip irrigation to keep things just right without overwatering.

Harvesting Lettuce

Cut-and-Come-Again Method

  • Suitable for early season
  • Harvesting outer leaves
  • Preserving the plant’s crown

This method is perfect for impatient gardeners like me who can’t wait for a full head to form!

Whole Plant Cutting

  • Mid-season harvesting
  • Cutting several inches above soil level
  • Allowing for regrowth

I love this method for a big harvest to share with neighbors and friends.

Full Plant Harvest

  • End-of-season method
  • Removing entire plant at soil level

When the season’s winding down, I’ll pull the whole plant and have one last big salad celebration.

Post-Harvest Handling

Cleaning and Preparing Lettuce

  • Chopping or leaving whole leaves
  • Washing process

A quick dunk in cold water perks up my lettuce leaves like magic.

Storing Lettuce

  • Drying before refrigeration
  • Using damp towels for humidity control

I wrap my lettuce in a slightly damp tea towel before refrigerating. It keeps the leaves crisp for days!

Final Thoughts

Growing lettuce from seed to harvest is a rewarding journey that anyone can enjoy. With a little patience and care, you’ll be enjoying fresh, homegrown salads in no time.

Don’t be afraid to experiment with different varieties – you might just discover your new favorite! Happy gardening, and may your lettuce always be crisp and delicious.
