Q: How do you get a foodie to eat iceberg lettuce? A: Give it a fancy French name! But seriously, this… ahem… “crisphead” is a real stunner with deeply serrated edges to the wrapper leaves giving the heads a regally ornate and frilled crown: truly the “Queen of Ice”. Compact plants show outstanding disease resistance in the field. Their texture is wonderfully crunchy, the color glowing green, and the flavor refreshing. 50-55 days. UO
Note: Seeds will become dormant if exposed to high temperatures. Lettuce grows best in cooler weather.
PLANTING DEPTH:
1/8-1/4"
SPACING:
12" in rows 15" apart.
EMERGENCE:
2-10 days @ soil temp 68F and lower.
LIGHT:
Full sun to part shade
FERTILITY:
Medium. Prefers well-drained, and evenly moist soil and is sensitive to low pH.
ADDITIONAL NOTES:
Uneven watering can result in tip burn, the browning of the leaf margins, which is the result of an inability of the plant to move calcium to the growing edge fast enough to meet its growth needs. Consistent, evenly moist soil or calcium amendments can be beneficial if this seems to be a problem.
Hot weather can cause premature bolting. Generally, when the plants begin to stretch upwards (to flower), the leaves become bitter and the eating quality poor.
