Some more things to remember
- Germination of lettuce is the most critical step – and requires some cooperation from the weather. Germination improves considerably when the temperature drops below 20 degrees centigrade
- Heading varieties of lettuce (like iceberg) require more cold to grow, but looseleaf varieties like Salad bowl are more heat tolerant, and don’t get bitter early. Romaine varieties are also a good choice for India.
- Lettuce seedlings take 21 to 25 days to be ready for transplanting, and need to be grown in nurseries before transplanting
- This is a cool weather crop and needs to be planted early in our climate (as the winter comes in) – avoid the heading varieties and grow looseleaf or romaines if you want to play safe
- Time to begin harvest of lettuce is about 45 to 50 days. Pluck a few leaves (not the youngest or the oldest) per plant every 4-5 days
