ecomes about the size of an egg ? I have a lush and healthy looking Avocado tree, approximately 15 feet tall, and 10 years old, that looks to have sprouted from a seed... Every year for at least the last 5 years, the tree looks to be loaded with small avocados, but when they get to be the size of an egg (maybe a little larger), they fruit turns black, and falls off... WHAT is happening? I have a number of other avocado trees that are much older, and they produce normal fruit... Is this a disease of some sort? Is there a cure ? I'm not familiar with this site... How will I know if my question has been answered?
It sounds like fruit rot. There are many pathogens that can contribute to this, unfortunately. Making sure to remove any infected fruits and discarding them far away from the tree will help. Using sulfur based fungicides can help, too.

My avocado twin saplings are now 10 inches and 8 inches tall: I've wrapped them like a braid and want to keep them small as I live in an apt. with no yard. I do want them to bare fruit though and was wondering how early I can pinch them back to make them branch out yet remain small enough for an inside plant. I want a tree about 3-4 feet tall.
You can go ahead and start pinching while they are young. You will have a better chance of getting fruit if you buy a dwarf variety that has been grafted. You may have to wait 10 years for fruit, and if it does fruit, it likely won't be as good as the parent. Those from seed make a nice houseplant though if you are happy with that.

WHAT IS THE BEST WAY TO START ?
Most people will recommend the "toothpick" method. I do not. I recommend taking a paper towel and getting it moist. Wring out any extra water, and wrap it around the seed. Place this in a sealable bag with just a little air. Place this ins a dark drawer. Check it once per week until you see a crack form. Once you see this, you can place the seed into a container.

We transferred a grafted, potted avocado tree that was thriving to our garden. The soil conditions were too wet and I believe the tree got root rot. We have been trying to save it by mixing gypsum, aerating the soil and adding mulch. Now the tree is doing better, budding leaves and actually blooming flowers. But, with recent rains and wind, now there is peziza badia mushrooms popping up all around the mulch which we plan to kill with fertilizer (see pic). If I eventually get avocados, will they be safe to eat? Your thoughts and recommendations are greatly appreciated. Thank you.
I think it will be fine to eat the avocados. They will be the next generation after the root rot, and the mushrooms shouldn't harm the tree or the fruit.

d. Can tree be treated This condition started about a year ago and is spreading up the toward upper branches and leaves. Tress was planted from seed about 15-20 years old.
There are lots of possibilities for the exudate on the trunk. If an injury causes it to leak sap, it dries in a white crystalline form. The gray-greener ones could just be lichens, which are harmless. The leaves though, do not look good. I've included a link to an article with a photo that looks a lot like your leaves. It could be drought stress, salts, high pH, etc., which are discussed in the article. I've also included a sheet on diseases with their symptoms, which you may recognize.

Fruit is large, about 4-5 inches by 3-4 inches. Placing n a paper bag for 2-3 weeks still resulted in hard flesh.

Hi, the hard frost two weeks ago really scared us. As new gardeners, we read the forecasts and covered our 26 avocado trees and 5 mango trees the best we could. We used mylar aluminum sheets (like mountaineers blankets), and the green thin blankets from the big box stored. Temperature went down to 26 F. The next day, when sunny and temp reached 46, we uncovered the trees to provide sun. They looked very sad and with some damage on the tips of the leaves. Two days after, all (ALL) the leaves where brown, crepe looking, crispy feeling. No leaves fell during the next week. We are not watering nor pruning yet. We don’t know what is the best thing to do now. Carl & Kate Lake Helen, FL
I would have opted to cover them with burlap. They probably suffered some suffocation damage.
As long as there is still some life to the tree it will, likely, come back. Next time, you may want to leave them to the frost, or cover them with burlap. That will do much less damage than mylar will.
