How To Grow Vegetables and Regrow Forever?

If you want a vegetable that regrows for decades plant asparagus. It's my favorite and I have an asparagus bed that produces each year.

Will depend on on the context really. Which is better as a snack - fresh fruit for me personally. It's tastier and gives you that little of sweetness. Which can be better as a snack if you are trying hard to slice back on sugar and lose weight vegetables

fruits and vegetables when unripe has starches as carbohydrates and becomes into fructose when it ripens.

If you want a veggie that regrows for many years place don't forget your asparagus. It's my preferred and I have an don't forget your asparagus bed which makes each year

Depends on the vegetable. Potatoes , just don't reap the entire crop. Carrots leave some in the ground to seed in the second season (they are biennials) . Peas and beans leave enough pods on the plants to reseed by themselves. Lettuce let a few plants go to seed. Cabbages same as carrots.

Growing is required to plant the seed ,but regrowing ,which I understand from your question (reproduce )by it self is a process that it require the vegetable get to flower and seed (which in this part they are not eatable and branches are getting thick).seeds in top of the plants get dried and wind or animals or even human can distribute the seed to around and those seed will grown again as temperature desire to grow.

Say fruit or nut instead of vegetable and plant a tree.

Perennial veggies include asparagus and rhubarb.

There are methods of to grow vegetables and repeated forever as shown below:
(1)Methods of growing vegetables:Some by seeds, cuttings, bulbs, corms, tubers etc. That act as the
starting materials for growing. As soon as they grow up after being nursed by preparation of suitable
cultivated methods such as soil, basic fertilizers, mulching and moistening etc. Then, you need to apply
watering,fertilizing, weeding and pesticides regularly or selectively till harvesting.
(2)Methods of regrow vegetables forever: There are varieties of vegetable for continual growing over two
years(perennials) which may meet your purpose, otherwise you might choose to regrow by using (1) seeding
pieces instead.

I like to grow potatoes in containers.
Start with an empty barrel, large pot or planter.
Scatter the bottom with shells stones or broken pots for drainage.
Put in just a couple of inches of soil.
Then place some potatoes that are sprouting. Or try some heirloom seed potatoes.
Gently cover the potatoes with soil & water.
When the plants reach about 6”, add another 2” of soil.
Each week add more soil to cover the bottom third of the plants.
When the soil nears the top stop adding soil. Water regularly & let the plants grow. They are nice looking plants.
They may develop little flowers that bloom & fall off. I have never tried to collect the seed. Sometimes you might not notice when they bloom. Shortly after the plants begin to fade (as if you forgot to water them). At that point stop watering and let them dry up for a couple of weeks. Then empty the container into a milk crate. The potatoes will get caught and the soil will fall through. You can use some of the smaller potatoes as seed for you next crop. In that way you can grow forever

Most vegetables are "Annuals". That means they grow for one season, produce seeds, and produce something that you can eat. Then the plant usually dies. However, you can usually gather the seeds and replant in the spring. You can also buy more seeds and replant in the spring, which is the way most gardeners do it.
