HARVEST GUIDE
When Is My Romaine Ready to Harvest?
YOUNG LEAVES
Harvest a few tender outer leaves once the plant is established and has enough foliage to spare. Young romaine works well in sandwiches, wraps and small salads.
REGULAR HARVEST
Take healthy outer leaves first while leaving the inner growth intact. This gives you smaller meal-sized harvests before the plant reaches full head size.
FULL HEAD
University of Maryland Extension says romaine is ready when the leaves have elongated and overlapped to form a fairly tight head about 4 inches wide at the base and 6 to 8 inches tall.
For the crispest texture, harvest when the leaves are well hydrated and still firm. If you are taking individual leaves, start with developed outer leaves and protect the younger center growth.
HOW TO HARVEST
Take What You Need — or Harvest the Whole Head.
1. Check the plant for healthy, crisp leaves.
2. For a small harvest, remove developed outer leaves with clean scissors or by gently cutting near the base.
3. Leave the younger center leaves intact if you want the plant to continue developing.
4. For a full-head harvest, cut the plant near the base once the head is well formed.
5. Remove damaged outer leaves.
6. Rinse thoroughly and dry before serving or storing.

HARVEST AMOUNT
How Much Romaine Should I Harvest?

GROW BETTER ROMAINE
Help Your Romaine Build Crisp Upright Leaves
- Give romaine strong light, consistent moisture, nutrients and good airflow. University of Maryland Extension classifies lettuce as a cool-season crop and notes that romaine forms an upright head. Indoors, avoid overcrowding and excessive heat, and keep the root zone evenly moist without leaving it waterlogged. Harvest developed outer leaves when the canopy becomes crowded.
Romaine size varies with cultivar, spacing, light, nutrition and maturity. Let the meal decide how much to take rather than expecting every plant to produce the same number of servings.
