I have an avocado plant that is now over 4 feet tall with an additional branching from the base that is about 2 feet tall. What do I do with this plant? My grandson and I started it from the seed and never expected it to really grow. HELP!
You can do some judicious pruning, no more than 1/3 of the branches at a time. This article will help: https://www.gardeningknowhow.com/edible/fruits/avocado/pruning-avocado-trees.htm
I have an avocado tree who grows too big for indoors. Can an avocado tree have frost?
Since they are generally susceptible to frost, most people choose to grow these plants indoors, though they can spend summers outside. If your plant has gotten too large, you can prune it back some to maintain its size. Here is more information: https://www.gardeningknowhow.com/edible/fruits/avocado/pruning-avocado-trees.htm
I have an avocado tree that I have grown from seed (outdoors in a container) and lately it has been developing brown spots on the leaves, and I have noticed some spots on the branches of the tree also. This plant is very special to me. I planted 3 seeds close together and braided the plants as they grew. It is approximately 4' tall now and I would hate to lose it. I live in Houston, Texas and it gets only the morning sun and I water only when the soil feels dry and use Miracle Gro when I water. What am I doing wrong?
It could be developing a fungus. Treat the plant with fungicide and see if this helps.
Started from pit, now 3 feet tall and no branches, just straight stock. So how to prune that to be a nice houseplant. Also, why do the leaves curl up and turn brown?
Pruning of indoor plants is much the same as trees that are typically grown outside. This article should help: https://www.gardeningknowhow.com/edible/fruits/avocado/pruning-avocado-trees.htm
As for the leaves curling and going brown, it is likely either a pest problem or a fungus, though a watering issue is also possible. I am leaning towards a fungus, based on the symptoms. I would recommend treating the tree with neem oil, which will treat both fungus and pests. Also up the water some.

I have a split pit from an Avocado I recently ate. I submerged its root in water and left the rest of it out of the water. Will it sprout and how long? And if it does, how and when can I transplant it, and where to? Thanks.

I have a young avocado tree and the leaves have fallen off and the limbs are turning black. Is there anything I can do to save the tree from dying?
This could be sooty mold. It happens when the plant gets a pest infestation. I would recommend using neem oil, as this will get rid of the sooty mold fungus and kill the pests. Here is some articles that will help you:

You can put it outside in the summer - if you have it indoors that might account for the drooping leaves (not enough light). I started mine (2) from seeds this spring and they've been outside since the nights stayed above 50 (I live in Zone 4). Both doing great. I plan on keeping mine in a sunny spot indoors ( house temp. kept at 68 degrees).
