Growing plants and vegetables is an exciting task but growing fresh new plants from old ones is even more rewarding.
All you need is a bit of time, sunlight and water to kickstart old vegetables into reproducing fresh shoots. This cost-effective method requires very little money and it provides an excellent talking point for the classroom.
Leeks will begin to grow again after just a couple of days in a glass of water by a sunny window. Use multiple leeks to have enough for a delicious potato and leek soup.
You may have seen a garlic sprouting before in your fridge, with a fresh green stem growing outwards. This is the perfect state to start another growing process.
3. Spring Onions
Spring onions are probably the easiest vegetable to regrow. You’re almost guaranteed results!
If you have a basil plant in your house, take a couple of cuttings into school and place them in water by the window. They’ll start growing roots that you can then plant in a pot.
Similar to the spring onions, you first start off in a cup of water. When the fresh inner shoots begin to grow, you’re ready to transfer to soil.
Just place the lettuce stalk in some good quality soil and watch it come back to life.
Coriander can be grown similarly to basil by pinching stalks and placing them in a cup of water until they produce roots.
Lemongrass will form small roots when placed in a cup of water for a few weeks. Once this happens, transfer to a pot and keep it in a sunny spot.
You can regrow ginger by soaking sections (make sure you have buds on each piece) of ginger overnight in water and then moving to a pot with soil.
10. Sweet Potato
When a sweet potato is partially submerged in water, it’ll begin to grow sprouts. It’s these sprouts that can be picked and planted in soil to grow a full sweet potato.
