▲Let it sit in the sun and change the water every day. You'll have some new spring onions in just a few days.

▲Gather a few stalks and cut them into 10 to 15 cm pieces. Remove the lower leaves, and leave just a few of the upper leaves.

▲Put the upper leaves in a glass half full of water under the sun and change the water every couple of days. When the roots are about 2 cm long, you need to move the plant to a larger pot, as it needs plenty of space and sunlight.

▲The way you plant mint is similar to basil. Gather about three pairs of mint stalks and cut them short, removing the lower leaves and leaving a few of the upper leaves.

▲You will then need to transfer the upper leaves to a larger pot with little holes in the bottom, as the plants need soil and plenty of water. Remember that the soil must always be damp.

▲Do the same as you did with mint and basil. Then plant the stems in a pot with holes so that the water can drain. The soil must be two thirds of coarse sand and one third mossy earth.

▲The plant must get sun, but doesn't need a lot of water. Cut a few of the stalks when you need them, and then replant it!

▲The garlic sprouts can be used in salads and the extremities are the tastiest.

▲Ideally you should place several carrot tops in a container and cover them half with water. They should start sprouting within 15 days.

▲Change the water when necessary. You won't be growing large lettuces, but they'll be good enough to use in salads.

▲Little yellow leaves will sprout, and then they'll become green. After five to seven days, move them to a pot with little holes filled with soil.

▲Cut about 5 cm off the stalks, put them in a recipient and leave them in a sunny place.

▲When the temperatures are lower, you can leave the leaks in the water. But if it's summer time, move them to a pot with soil as soon as the roots start to grow.

▲Then move them to a pot with soil. Leave the plant in the sun, as it can take the heat well, but don't forget to water it.

▲When the potato starts growing new sprouts, you can use those to replant them in earth.

▲Use the onion root that you would otherwise throw away and put it in a glass covered with about 2.5 cm of water.

▲The lower part of the Chinese cabbage can be used to grow a new one.

▲Ginger also sprouts after a while, so take the sprouted part and leave it overnight in lukewarm water.

▲

Then move it to a pot with soil with the sprouted side up. Make sure the water is able to drain from the pot.

▲Just like garlic, carrots don't need to be replanted. Use the carrot tops and put them in a container with a little water.

▲

Take the white part and some of the stem of the spring onion and put it in a glass, covering it with about 2.5 cm of water.

▲

Similarly to celery, use the lower part of the plant (the root)⁠—the part that's usually discarded.

▲

Just place that part in a bowl with a little water and voilá!

▲

After the roots start growing, move them to a pot with good quality soil in a sunny place.

▲

Potatoes will usually sprout after a while. Use those and place the potatoes with the sprouted side up in a glass filled with about 8 cm of water.

▲

Take five or six stalks of lemongrass and put them in water until the roots start growing.

▲

The plant grows from the bulb so you just need to put the cloves in a glass container with water.

▲

Take the lettuce core that you would otherwise throw away and put it in a bowl or glass with water.

▲

Cut about 5 cm of the celery stalks and put them in a bowl with water and leave them in a place where they are exposed to sunlight. Make sure you water the tops as well, so they don't get dry.

▲

Leeks belong to the same family as spring onions, so they will sprout in water. Cut about 5 cm off the lower part of the stalks, including the roots, and place them in a recipient filled with just enough water to cover the roots. Just be careful so that the water doesn't evaporate.
