The avocado seed has two very different ends, one end where the roots grow from and one where the stem and leaves will sprout. If your avocado seed is perfectly round it can be hard to tell, but most will have a slightly pointy end. This is the up side where the stem comes from. The flatter end is the root end, or the ‘bottom’ of the seed which needs to sit in the water.
Tip: To make your avocado plant grow nice and bushy, cut off the top leaves just above a pair of buds on the stem. This will make it branch from the sides. Do this regularly as the plant grows.
When you grow an avocado from seed it won’t be the same as the tree the seed came from, because that tree was a special hybrid variety not grown from a seed. It’s a game of chance; your tree might give you fruit one day. But you might be all grown up before it does! In the meantime you can enjoy watching it grow into a pretty garden tree or houseplant.
Avocados are some of the biggest seeds of all but there are bigger seeds. For example, a coconut is a seed waiting to fall on the ground and grow into a coconut palm if it’s not harvested and eaten. The largest seed in the world comes from another kind of palm tree called Coco de mer. This seed grows 30cm long!
Avocados are very good for us and contain more fat than any other fruit or vegetable. Avocado fat is healthy fat, one of the best foods for energy.
In prehistoric times avocados used to be eaten whole by giant sloths and other giant mammals which are now extinct. They would help to spread the seeds around with their poop.
