June Lettuce Planting

LAKE MACBRIDE— According to a local organic farmer, “one of the most common mistakes home gardeners make is not planting sequentially.” What does that mean?

Certain crops, like lettuce, spinach and radishes, have a short planting to harvest cycle, and multiple crops can be planted during a season. That is, as soon as one row is harvested, another can be planted as long as the plants can tolerate weather as it get hotter and dryer.

What I learned at the farm this year is that lettuce produces the best crops when they are planted as individual seeds in a starter tray, then transferred to the garden as seedlings when the ground is ready. This accomplishes two things.

First, and this is really important, when planting lettuce, plant individual seeds, using a starter tray, or an old egg carton. Because lettuce seeds are so small, the temptation is to sow more than one together. By using a starter tray, and one seed per cell, if one cell fails to germinate, no problem when planting the seedlings in the rows in the soil. If the seed didn’t produce in the starter tray, there is no seedling to transplant. Planting single seeds ensures sufficient moisture and nutrients for each head of lettuce by avoiding over-crowding. It makes for larger leaves.

Second, by planting seeds in trays, the garden space can be more productive. A four week old seedling will take less time to mature once it is planted in the garden. If timed properly, a garden can be in lettuce most of the summer, into fall. For example, I have two and four week seedlings started in successive trays. They’ll be ready to plant when the current crop is harvested.

Avoid a common mistake, plant lettuce sequentially this June.
