I have received a lemon tree as a present. I wish to know when I can safely place it outside, and if I protect it with a geotex cover, can I do it sooner?
Lemon trees thrive within a normal temperature range of about 70 degrees throughout the day and 55 degrees at night. Keep in mind that they will usually go into dormancy when temperatures fall below 55 degrees F. For those grown in containers, the temps should be higher.

This tree is planted in Houston, TX (several years, no fruit) and now has small green lemons growing on almost every branch but there are tiny yellow ones falling off. What is causing this? I got my first full grown lemon that fell off the bottom this week and is delicious but will the other nickel, quarter size green ones grow? Over the years they never have fully developed until that one the other day. Some leaves are "curling" and die, is that a fungus?
It sounds like your tree is not getting enough water so it is aborting fruit to try to help reduce the amount of water it needs. Increase water to the tree and this should help stop the fruit drop and leaf drop.
I will warn you that when you initially increase water, you may see increased leaf and fruit drop for a few days after. This is a citrus tree's natural reaction to getting enough water after lacking enough. It is an odd way for a tree to react but is normal in citrus trees.
Have lemon trees in 10 gallon pots. Granule fertilizer did not do too good so am looking for liquid fertilizer. What would you recomend, and where can I buy it?
Thanks,
Ray

What are the best natural solutions for a citrus whitefly infestation and sooty mold all over the leaves (due to the citrus fly, I know) on my lemon tree? What is an alternative to using Liquid Gold Copper for the sooty mold, which I can't get a hold of here in Argentina?
I would recommend neem oil. It will take care of both the pests as well as the sooty mold. Here is more information: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm
My indoor/outdoor lemon tree is sticky and has broken leaves. And does not look heathy.
It has a pest, most likely scale or aphids. These articles will help:
