Crisp Mint Lettuce (60 Days)

The search for lettuce that tolerates the hot months of summer could be over for you. We have always loved Jericho but the Crisp Mint Lettuce has proven to be a worthy rival. The ruffled mint-colored leaves are crisp and sweet even in elevated temperatures. Young heads are rather open but tighten up as they mature, growing to a sturdy 10”. Harvest mini or full-sized. Experiment by growing this as cut-and-come-again lettuce, (we discovered this is possible thanks to our resident groundhog).

PLANTING

Lactuca sativa

Germination: 4-10 days

Germination Temperature: Optimum soil temperatures are 60-75ºF. Soil above 75ºF. inhibits germination.

Outside Sowing: Spring when the soil temperature reaches at least 50ºF. Sow 1” apart, thin to 6-12”, depending on the size of lettuce you want, baby to full heads. Keep soil moist during germination. Sow every 2-3 weeks for a longer harvest period. Sow heavy seeded rows every 10-14 days for baby greens using 1 oz. Pinetree Lettuce Mix.

Starting Indoors:  3-4 weeks before planting outside. Sow 2-3 seeds per cell/pot, thinning to one per cell/pot. Provide 60-70 ºF. soil temperatures. Transplant out, 8-12” apart in rows 12” apart.

How much does a packet plant: 25-foot single row  

Harvest: Cut whole heads at the base or snipe off individual leaves.  

Tips: The Crisp Mint Lettuce needs fertile soil for optimum growth. Work in compost or well-rotted manure into your soil before planting. Provide adequate, even moisture for the best growth. Mulching helps retain moisture.
