How Deep To Plant Lettuce
The dept that is ideal to plant lettuce seed is around 1/8 to ¼ of an inch deep. It is important you don’t sow lettuce seeds too deep. This is because lettuce seed requires light to germinate so, if the seed is too deep, light may not penetrate the seeds and this may lead to unsuccessful lettuce seed germination. Also, make sure you sow the seeds of lettuce when the soil is not frozen.
Additionally, to successfully sow lettuce seed, you will need a well-tilled seedbed. Note that stones and large clods of dirt can slow down seed germination. So ensure the seedbed is clear of any obstacles such as these.
Starting Lettuce Seeds – How Deep To Plant Lettuce
You can start your lettuce seeds either indoors and then transplant or sow them directly in the garden. How deep to sow your lettuce seeds should be 5mm (1/4”). Or you can plant them where there will be all-around moisture in the soil which is the topmost layer of the soil.
Because the baby lettuce is usually ready for harvesting while it’s immature, it should be planted densely. Unlike other types of lettuce seeds that don’t really need covering as they are usually planted right at the surface, you should plant pelleted seeds 1cm (1/2”) deep.
Your pelleted seeds need to be all-around moist when planted newly. Water it more than the way you would have watered the conventional seed variety. However, leaving the soil to dry out will only make the pelleting material suck water from and cause dehydration for the seed.
This is because the pellet material is clay. This action will lead to a more unpleasant situation which is unequal or lower sprouting. So, give space between thin loose leaf varieties to about 20-25cm.
As for the heading lettuce varieties, give space of about 30cm between them. Give space of about 45-90cm between rows, for all types of varieties. Also, harvesting can be made easier if baby leaf lettuce seeds are planted by each other in rows that are narrow.
Tips On Growing Lettuce
The best soil to grow lettuce in is the type that is well-draining and also high in organic matter. Ideally, the soil pH for growing lettuce must be between 6.0-6.5.
Before planting your lettuce, say 3 weeks, endeavor to mix compost and lime into the soil. Once it’s 2 or 3 days to transplanting, reduce watering and also move your lettuce plants outdoors.
This will help harden off the seedlings before transplanting and it will prevent shock transplant. So, this way premature bolting and transplant shock can be avoided.
