Spring onions -

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.

Spring onions -

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

Basil -

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.

Basil -

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.

Mint -

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.

Mint - 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.

Rosemary - 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.

Rosemary -

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!

Garlic -

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

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

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

Carrots -

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

Romaine lettuce -

Romaine lettuce -

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

Celery -

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.

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.

Chard -

Similarly to celery, use the lower part of the plant (the root)⁠—the part that's usually discarded. Cut about 5 cm off the stalks, put them in a recipient and leave them in a sunny place.

Leeks -

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.

Leeks -

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.

Lemongrass -

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

Lemongrass -

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.

Potato and sweet potato -

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.

Potato and sweet potato -

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

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

Onions -

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

Chinese cabbage -

The lower part of the Chinese cabbage can be used to grow a new one. Just place that part in a bowl with a little water and voilá!

Ginger -

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

Ginger -

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