Regrow Your Old Vegetables

We all love to save money where we can but have you ever thought to recycle your old vegetables and grow healthy new ones. That is right you can grow almost anything in your garden without buying fresh from the supermarket.

Gardeners have done this for years although some growers of non-organic vegetables may now treat them with sprout-suppressing chemicals, which prevent re-growth. I have kept tomato, cucumber and capsicum seeds from produce I bought fresh from the supermarkets. The plants grow from the seeds, although they never produce any vegetables.

For that reason, I suggest you collect seeds from people who have grown their own vegetables for years so you know they will continue to produce fresh vegetables or salads for you.

These can be grown in a vegetable garden or mixed in between flower beds or anywhere in your garden to add nutrition to the rest of your soil.

Types of Vegetables You Can Recycle

Most vegetables can be regrown

This article will show you how to recycle potatoes and sweet potatoes although you can regrow these vegetables too:

  • Potatoes
  • Sweet Potatoes
  • Celery
  • Silver beet (spinach)
  • Onions
  • Bok Choy

Like other vegetables, there are different types of potatoes and the way they are grown. You can buy normal unwashed ones sold with the dirt still on them.  Although many sellers are now rolling the old ones, in the dirty soil to pass them off as newly dug potatoes so watch out for these.


These are the same as above, except they wash and pack them to look more appetising on the supermarket shelves.


The skin of these are pink in colour when peeled they seem a deeper yellow than the white spuds. I prefer the white myself.

How to reproduce healthy Potatoes from old ones

You can reduce the risk of eating chemically treated vegetables by growing your own more economically.  If you speak to the gardening experts they will tell you to buy seed potatoes, and yes you can do this. As I am talking about being frugal, why waste money buying them when we have potatoes in the cupboard that quite often start shooting, ready to grow?

How to Reproduce Healthy Potatoes from Old Ones

Grow Potatoes from the Peelings

For the people who peel their spuds, do not throw those peels away.  If you look closely at them, you will see little eyes in the peelings.  That is how your potato will shoot. 

Soil Preparation

There is no need to do anything special to grow potatoes other than digging up the ground.  Make a trench and put the peelings in the hollow. Cover and water well. They will shoot in a couple of weeks.

When the leaves and stems grow heap mulch or soil around the plant to form a hill.  This will prevent the potato from showing above the soil and stop it from going green. As the plant grows heap more soil around the stem of the plant. Potatoes are ready once the leaves turn yellow although you could sneak one or two if careful without disturbing the roots too much. They say you should never eat green spuds, as they are poisonous, although I believe you would have to eat a fair amount before it would be harmful.

Grow potatoes by cutting the end with eyes off

Before you cook them with the skins on, wash to see any imperfections.  You may notice that some potatoes may be spoiled or damaged. If your potato is green or damaged, cut the end with the eyes off. Leave this on top of the soil to dry for a day then plant in the same way as mentioned above, although a little deeper. Plant your old whole spuds as above and produce more.

I remember people growing potatoes in their front lawns before planting the lawn because it encouraged better lawn growth. This also helps to improve your soil before planting a new garden.

Did you know?

You can grow your spuds in straw or hang a sack on the wall and fill with straw. Plant the potatoes and water as you would when planting in the garden. By planting in hay or straw, it reduces the need to dig the spuds, and they stay clean too.

  1. Cut an old sweet potato in half
  2. Place both halves in a dish of water cut side down
  3. Place these in your kitchen window box or near well-lit window
  4. Leave for four-five weeks keeping the water up until they shoot
  5. These shoots will be your new sweet potato plants, most will form their own roots.
  6. Break these new plants off and plant into the freshly prepared potting mix in garden or pots.

Keep indoors if cold weather. When frosts over, take pots outside or re-plant in garden when stronger.  Water and watch them grow. 

Did you Know?

When your sweet potato plants produce runners like in the picture below, you can cut these off and plant cut end into the ground, leaving the end of runner above the ground. These will also grow and produce sweet potatoes.

Sweet Potato Chips

Sweet potato chips taste better than your normal deep-fried potato chips.  Therefore, once you have them growing in your garden, you can cut them up and eat at your leisure.

Why should I have a Vegetable Garden

Because you will enjoy growing and eating your fresh grown vegetables knowing they are free from chemicals and of course start banking the money you save by growing your own.

Did you know that you can also be a frugal gardener by growing other plants from cuttings?

I hope this article will encourage everyone to grow their own fresh vegetables from older vegetables.
