Why is lettuce bitter?

Natural conditions make lettuce bitter.

The bitterness of some lettuce is caused by natural conditions. The most important point is that the growth time is too long and the light conditions are poor during the growth period, which makes the amount of sweetener in lettuce less and makes it bitter. In order to avoid this situation, when you plant lettuce yourself, you must harvest it in time and don't let its growth period be too long.

2. Improper fertilization caused the lettuce to be bitter.

When planting lettuce, improper fertilization will also lead to bitter lettuce. When lettuce lacks nitrogen fertilizer during its growth, it will make lettuce bitter. The best way to avoid it is to apply enough fertilizer and try to provide enough nitrogen fertilizer for lettuce during its growth.

In addition to not eating bitter vegetables during the growing period, there are also certain treatment methods after buying bitter vegetables. The best way to treat lettuce is to cut it into pieces and soak it in clear water, which can make its bitterness fade. You can also blanch the lettuce with boiling water, which will reduce the bitterness of the blanched lettuce. Add some garlic paste to make a cold salad, which tastes good and can clear away heat and detoxify.
