I think plants are pretty cool... so I decided to share my love of plants by submitting an Instructable on growing your very own avocado tree. This is a pretty simple process, but if you have any questions please ask me.
I do not have any photos right now of the finished tree because I cannot travel through time. I will submit sideshow on the growing tree when it starts growing.
What you need:
Something that will cut a Styrofoam cup
...and water .-
Step 1: Find a Seed
Avocados are potato sized greenish-black fruits (I think they are fruits). The best time to harvest a seed from an avocado is when it is ripe. If the color is Purple, green or purple-green, it is not ripe. If it is greenish-black in color it is ripe and you can harvest a seed from it.
To harvest the seed, simply cut the avocado in half ( widthwise or lengthwise,it does not matter) and GENTLY scoop out the seed (with a spoon, dork). Be sure not to severely lacerate the seed in the process of cutting the avocado in half.
