I found this...
How do I care for my avocado tree?"
Keep your tree in a sunny window, the more sun it gets the bigger it will grow.
Remember to give it frequent light waterings but don't let the soil get muddy. If the leaves turn yellow it means that the plant is getting too much watering, let the tree's soil dry out for a couple of days, then return to light waterings.
When the stem grows six more inches pinch out the top two sets of leaves. This will encourage the plant to grow side shoots and more leaves, making it bushy. Each time the plant grows another six inches pinch out the two newest sets of leaves on top.
"Can my avocado tree ever go outside?"
Yes it can go outside in the summer. If your winters are cold ~ below 45 degrees (F) or 7 degrees (C) ~ you must bring your tree inside for the winter. Otherwise, if your winters are cool and mild, the tree may stay outdoors year round.
