Avocado Rate of Growth

How fast does an avocado tree grow? Well, this picture indicates how much new growth occurred in just under one month. This young tree started life as a seed from an avocado I bought at the grocery store back in October 2006. Instead of throwing out the seed, I shoved some toothpicks in it and watched it sprout. I pinched the top quarter inch off the top about a month and a half ago and within two weeks it sprouted two little nubs (shown in the upper right of the second picture). Less than one month later, the two nubs grew into two long stalks that are now about 12 inches each!
