Growth Stages
Seedling
7-10 daysTiny cotyledons emerge with true leaves appearing shortly after. Plants are delicate and low to the ground.
Keep soil consistently moist. Thin seedlings to proper spacing once they have 2-3 true leaves. Protect from heavy rain or overhead watering.
Vegetative Growth
15-25 daysLobed or frilly leaves develop and expand rapidly. Plant reaches 4-6 inches in height with multiple leaf clusters forming.
Maintain consistent moisture. Apply balanced fertilizer every 2-3 weeks. Mulch around plants to retain moisture and regulate soil temperature.
Leaf Development
10-15 daysMature leaves become deeply cut or lobed with a vibrant green color. Plant becomes full and bushy.
Begin light harvesting of outer leaves. Monitor for pests. Ensure adequate water during dry spells.
Peak Harvest
7-14 daysPlant is fully developed with abundant tender leaves ready for harvest. Leaves are flavorful and at optimal texture.
Harvest regularly by removing outer leaves to encourage continued production. Cool weather extends this stage.
Bolting
Varies by temperatureCentral stem elongates and flower buds begin to form. Leaves may become bitter and tougher.
Harvest immediately if planning to use for greens. Plant is past peak quality; consider succession planting for continuous harvest.
Common Pests
-
Use row covers on young plants. Spray neem oil or insecticidal soap. Maintain adequate moisture to reduce plant stress.
-
Hand-pick caterpillars. Use Bacillus thuringiensis (Bt) spray. Install row covers to exclude adult moths.
-
Spray with strong water stream to dislodge. Use insecticidal soap or neem oil. Encourage beneficial insects like ladybugs.
-
Ensure good air circulation. Remove affected leaves promptly. Avoid overhead watering. Apply sulfur or copper fungicide if needed.

Harvest Tips
Begin harvesting outer leaves when plants are 4-6 inches tall, approximately 30-40 days after planting. Pinch or cut leaves from the outside working inward to encourage continued growth. Morning harvest yields the crispest leaves. Cut leaves will regrow for multiple harvests over 2-3 weeks. Harvest before bolting occurs, which is triggered by sustained warm temperatures. For baby greens, harvest entire plant at 2-3 weeks; for mature leaves, harvest selectively over time.
