The avocado seed should be sown when it is as fresh as possible since it
does not retain the ability to germinate for very long. Most of the seeds
are oval and are sown with the pointed end upwards.
There are two methods of sowing an avocado seed.
1. Normal: the seed is put in a pot with light porous soil, and with one
third above the surface. Keep the soil moist but do not overwater. Keep
the pot in a warm place but with some shade.
2. Glass: another way to start off an avocado plant is to stick three
toothpicks carefully in the avocado seed and hang it up over a glass of
water. The water should just about reach the seed, but at the same time
there must always be enough water in the glass to keep a constant humidity
around the seed. After about 4-8 weeks, the two halves of the seed will
be pressed to one side and a root will grow down into the glass. You can
now carefully plant the seed in a pot, but make sure that you do not
damage the root--it is very fragile and can easily be harmed.
Potting: the young plants grow very quickly and need a lot of
nourishment. You will need to re-pot often in a good nourishing soil.
