Gardening and Horticulture - avacado's

I would like to know if anyone has any information on how to start an avacado plant/tree from a seed from an avacado that you purchased from a grocer...thank you!!!

There are 2 ways you can do this.

Make sure all green flesh is removed from the seed (rub under running water). Then, take a look at it. There should be one end that has a small brown disk on it. This is the bottom. Take the seed, and plant it bottom down, it a pot so that about 1/3 to 1/4 of the seed is sticking out the top. It will take a while to get going, but if you keep the soil moist it will grow. Keeping it warm helps, too (but not too hot!).

Alternatively, if you want to watch the beginnings of germination (this is especially fun for kids), take 3-4 toothpicks and stick them in the seed about 1/3 to 1/4 of the way down from the top, so that they radiate out like spokes on a wheel. Then place the seed in a glass of water, so that the toothpicks support in partially out of the water. Be sure to keep the water full so that 2/3 to 3/4 of the seed is covered at all times. The seed takes a little while to germinate, but when it does you will see the tiny root emerge. Using the soil method it is easier to keep it from drying out, but you have to wait longer to see the sprout emerge (because the first growth is underground).

Thank you for your help...we have two ready to go!! Will try your methods...one with each and check their progress...you wouldn't know how long it takes to sprout would you?? But if not...no matter...Thank you!! it was much helpful!!!

gosh, I haven't done it in years. I think it took a good 2-3 weeks to see any growth.
