Growing an avocado seed in water. We suspended the seed of an avocado in a jar of water using 2 paper clips. After a few days the outer brown skin disintegrated. Then a small root appeared.

At 3 weeks After 3 weeks the root was about 3cm long.

At 4 weeks After 4 weeks the root was 7 cm long. We topped up the water regularly.

At 6 weeks After 6 weeks the root had reached the bottom of the jar and a green shoot had appeared.

At 7 weeks After 7 weeks the jar was too small and the root began to turn upwards.At this point we decided to place it in a pot.

At 10 weeks After 10 weeks we had a plant 30cm high.
