I've tried direct sowing lettuce before. I don't get good results. Why? The seeds are so small that I just toss them. Then stuff grows and I don't thin it out properly. I always feel bad about yanking plants out that are growing well. Then they get too crowded and don't do well. I've found that I can avoid this by starting lettuce in pots. I throw in a pinch of seeds and when they first sprout I take out all but one of them.
A few weeks ago (probably in May) I started lettuce seeds in my garage. It took them a while to get going, but they've done well. I've kept them under shop lights. Rather than dealing with watering each individual container I put them in trays. Then I pour the water in the tray and it gets absorbed from the bottom up.
|I started a lot Romaine, and some leaf lettuce|
|Romaine at various stages of growth.|
|There are two big Romaine heads in the back and a smaller one in front.|
|I cut back my oregano to make room for this one.|
|This is some leaf lettuce I put in the other day.|
|I even put lettuce in my front island next to a blueberry bush.|
|After cutting bunch of lettuce for dinner tonight I had room for this one. It was a little sad, but some water should cheer it up.|
