When daytime temperatures get warmer, it will only be a matter of time before cool season lettuce that we planted in early spring bolts. Bolting is when lettuce starts to get a center stalk and eventually it will make flowers and become bitter. What makes lettuce bolt? Both summer heat and more sunlight in our longer sunnier days contribute to bolting. If you find your too late and it is already bitter, either compost it or give it to chickens. They don’t seem to mind the bitterness.

I read a tip where you can make bitter lettuce sweet again so I decided to try it as my winter lettuce is pretty much finished and bitter. The tip said to mix up 4 TLB salt with 1 liter of water till dissolved in a bowl and then soak your lettuce in it for ten minutes. Then rinse and it should be sweet. I did try it and the lettuce got totally wilted. Not edible. After I rinsed it, I soaked it in fresh water hoping to revive it and the lettuce was still salty and wilted. Still not edible. I didn’t even want to give the wilted lettuce to my chickens or compost it for fear of too much salt still in it. Oh well, so much for that tip!

If you still have lettuces that haven’t been picked, get out there soon before they bolt! To get the best from your lettuce, water your plants the evening before you plan to pick it. Then pick lettuces first thing the next morning before it gets too hot. After I wash it and spin out the water, I put lettuce in a ziplock baggie with a wet piece of paper towel folded (squeeze out excess moisture). Lettuce should last a good amount of time when doing this in the refrigerator.

There are other lettuces we can grow here in the shade in the summer. I will write a post soon about growing these warm season lettuces for the summer that are heat resistant and don’t bolt. They are called Batavian or Crisp lettuces. More on that later.
