How to Grow Bibb Lettuce Plants
Bibb Lettuce plants are a heading variety of lettuce. It forms a loose head.
It is tasty, with a distinctive flavor that's popular with home gardeners.
Like other lettuces, Bibb lettuce is a cool weather crop. Time your
spring crop to mature prior to the onset of hot and humid weather. Summer's
heat can result in splitting bolting, or rotting of heads. We recommend an
indoor start in the spring for an early crop for your salad bowl.
How to Grow Bibb Lettuce:
Bibb lettuce seeds can be sowed directly into the garden, or started indoors.
Direct sow seeds outdoors, spreading these small seeds as thinly as possible.
For indoor starts, sow a few Bibb lettuce seeds in each cell of a seed tray.
Cover very lightly with a fine starter soil. Keep soil moist during the
germination period. In about 7-10 days, the seedlings will sprout. Thin
seedlings, after they are about 1/2" to 1" tall. To avoid disturbing the
roots, snip plants off at the base, leaving just a few to continue growing.
Tip: When beginning transplants, stagger the start of your seedlings
to spread out the crop. For example, if you are going to plant 24 plants,
sow seeds into six cells or peat pots. Sow six more 4-7 days later, etc.
Transplant into the garden after all danger of frost has past. Ideally,
transplant them on a cool or cloudy day. Water well after transplanting.
Space plants 10" apart, in rows 18" apart.
Like other lettuces, the trick to growing Bibb lettuce, is to grow
it quickly. The soil should be rich, fertile, and well draining. Keep the
soil moist. Frequent use of nitrogen rich fertilizer is recommended. The
plants respond well to regular applications of liquid fertilizer and
Transplanting Tip: When transplanting any type of lettuce in hot weather,
place some form of sun shade over the plant for a couple of days. Any makeshift
shade will help to minimize transplanting shock.
It's important to time the crop to mature prior to the onset of hot
dry weather. In these conditions, the plant is bolt...go to seed. It can
also split or rot.
For your fall crop, an indoor start is best. Lettuce seeds do not germinate
well in the hot soil of mid-summer.
