Learning how to re-grow vegetables from store-bought is not one of those practices I'm going to abandon when food supplies become plentiful. This practice is here to stay. The chickens may never taste the root ends of celery, lettuce, or onions again.
About a week or two ago, in response to the difficulty individuals across the country were having in obtaining vegetable seeds, the internet exploded with references to YouTubes and articles about propagating vegetables from grocery store produce. After all, such information could be really practical at this period in our lives. If true, this is basically free food without any real effort on our part.
The articles focus primarily on three different categories of food production. Today's blogpost will only lightly touch on the first type, since those foods aren't trash, and go into much more detail for the other two categories.
The first category uses perfectly good food to produce more food. This involves root crops like ginger, garlic, and potatoes. Ginger is a tender plant that must be grown indoors in most of the US, but it's easy to do. Garlic is a favorite many are familiar with raising in their gardens each year. One must be wary of planning to use store-bought potatoes for gardening, however. Most are sprayed with a sprouting inhibitor and may slow to sprout, yielding little to nothing in the garden. So keep that in mind.
Now on to the vegetable "trash" that can be used to produce more food.
In this second category are root crops. While neither carrots nor beets will regrow the root vegetable, both carrot and beet tops can be replanted to produce more greens. Even if you are not interested in eating them, they can be a great way to raise some fresh greens for chickens and rabbits.
- Carrots. Carrot tops aren't commonly eaten as food in this country, but they are considered edible and may make a fine addition to salads and soups. Remove the carrot top greens. For planting in the soil you want the top end with about 1/2" of carrot included. Plant this in the soil with about 1/4" of the top above the soil surface. Leaves will start appearing within about one week.
- Beets. Beet greens are much more likely to grace the dinner table in salads or sauteed as a side dish. Remove the beet greens. Like with carrots, for planting in the soil you want the top end with about 1/2" of beet included. Plant this in the soil with about 1/4" of the top above the soil surface. Leaves will start appearing within about 10 days.
- Green onions. When slicing up green onions, leave at least 1/2" of onion attached to the root end. Plant so that the top is just barely above the soil surface.
- Leeks. Begin with leeks that have healthy-looking roots. When slicing up leeks, leave 1/2" of leek attached to the root end. Plant so that the top is just barely above the soil surface. New growth will begin to appear within two weeks.
- Bok choi. Save the bottom 1 1/2" of the bok choi for replanting. With a sharp knife, remove a very thin slice from the root end, just enough to expose a fresh surface for growth and rooting. Plant the root end about 1/2" deep in the soil. New leaves will start growing in about two weeks.
- Lettuce. Save the bottom 1 1/2" of the lettuce head for replanting. With a sharp knife, remove a very thin slice from the root end, just enough to expose a fresh surface for growth and rooting. Plant the root end about 1/2" deep in the soil. New leaves will start growing in about two weeks. Propagating lettuce in this way has about a 50% failure rate.
- Celery. Save the bottom 1" of the whole celery (not individual stalks). With a sharp knife, remove a very thin slice from the root end, just enough to expose a fresh surface for growth and rooting. Plant the root end about 1/2" deep in the soil. New growth will appear in about 10 days.
Using the root ends of these vegetables gives you a huge head start on growing, especially with crops that take much longer to reach maturity like celery and leeks. Furthermore, when it's time to harvest, you don't even have to pluck these ones out of the ground. Just cut them off about a half-inch or so above the soil surface and let them start regrowing again. They already have their root systems well established and won't suffer from any transplant shock.
And don't cease your growing in the winter. All of these may be grown indoors during the off-season in a sunny window or with grow lights.
