- Lettuce is one of those crops whose fresh picked taste simply cant be equaled by anything you can buy at the grocers.
- Most lettuce varieties are not yet grown commercially in any quantity .
- Greens dont travel or store well.
- No store could possibly stock the amount of lettuce varieties you have available to grow.
- Greens are relatively easy to grow.
- Greens are high in mineral, vitamin and fiber content.
- It is cheaper to grow your own lettuce than pay premium prices for gourmet greens.
- Lettuce is a cool season crop and consequently is best grown in either spring or fall.
- However, lettuce likes a temperature around 70o to germinate, so early plantings should be started as plugs.
- Lettuce seeds need light to germinate. Just barely cover the seed with soil.
- After a couple of weeks check to see if the roots have branched out to the sides of the plug. If so, they are hardy enough to go in the ground.
- Dont let the seedlings get too large before placing them out.
Care & Feeding of Green Crops
- If you have fertile soil, you shouldnt need to feed lettuce plants, unless you plant the cut and come again varieties all summer. This is one crop where extra nitrogen cant hurt, since all you want from the plant is leaf.
- Well-rotted manure or compost is ideal.
- The plants will need regular watering, as lettuce tends to have a shallow root system.
- Dont keep the area damp or use mulch or you will be inviting slugs.
- A lettuce crop is ideal for the intensive gardening method which is getting a lot of attention lately, because it matures rapidly, can be planted quite closely and can be planted in succession if you choose seasonal varieties.
- Lettuce can even be grown in containers or used as a decorative border.
- If your lettuce looks like its about to bolt, pull it out of the ground, roots and all, and replant. This shock to its system will slow its growth. Keep well watered.
- For the longest harvest, direct seed or transplant every 7-10 days.
- When direct seeding, seeds can either be broadcast and planted in wide rows or spaced 8-12" apart. Spacing is best if you want it to mature into heads.
- If you are going for heads, be sure to harvest before the head starts to elongate. That means its ready to bolt and the flavor will suffer.
- And be forewarned, maturing to a head takes time and therefore makes it more difficult to grow without bolting than the looseleaf varieties.
