We’re on the brink of starting to harvest our first outdoor lettuce, switching over from the last of the baby lettuce mix in the hoophouse. Our goal for this transition is April 15, but naturally the exact date will depend on the weather in the spring, the coldness of the late winter, the rate at which we are eating lettuce and other factors beyond the grower’s control.
We make three sowings of baby lettuce mix: 10/24 to harvest early December to early March (after we’ve cut it several times, and it is starting to tun bitter); 12/31 to harvest from late February till the end of March Later if it doesn’t get bitter from hot weather); and 2/1 to harvest mid March to the end of April. This year the #2 sowing is still edible in mid April, so we have two patches feeding us for a little longer.
Our winter salad mixes are very popular, but we can only continue with those as long as the spinach and the salad brassicas hold up. Part of me is always sad to stop eating salad mix, but the other part welcomes the juicier, crunchier, tastier head lettuce. Baby lettuce mix is very pretty, but honestly I find it a bit short on flavor and texture! It’s the other ingredients in the salad that make it interesting for me, especially spinach.
The first outdoor lettuce were sown 1/17, planted out 3/9, to feed us 4/15 to 5/8, when the second sowing should be ready. We cover these with rowcover on hoops when we transplant, for about a month, or until the weather seems settled at a reasonable temperature.
Our raised beds outdoors are 4 ft wide, with 1 ft paths. we plant four rows of lettuce, spaced 12″ apart, and plant about 120 from each sowing. That usually fills a third of a 90 ft long bed, so we have 3 different plantings in each bed of lettuce. We continue at this pace until our last outdoor plantings around the fall equinox.
This spring we are going to continue the salad mixes a bit longer by harvesting the outdoor lettuce by the leaf. We have lots of really good looking spinach to mix in, and the last few mizuna and ferny mustards. We used to only sow these twice, 9/24 to transplant in the hoophouse, and 11/9, which feeds us until late March. We added in a third sowing of mizuna and ferny mustards 2/1 which we harvest 3/24 to 4/23 approximately. That extra month is really worth having!
We also have a short row of Sugar Ann snap peas in the hoophouse (sowed 2/1) that we like to snip into thirds and add to salad mix. This makes for a nice little surprise for everyone. We couldn’t feed a hundred on 50 ft of snap peas! These are an incentive to keep the salad mixes going while the peas are being harvested.
