I have a lemon tree about 5' high in a 12" pot indoors. It has started to drop its leaves. How often should I water it?
Leaf drop is a common problem in both lemon and lime citrus trees. Here is an article that you may find helpful: https://www.gardeningknowhow.com/edible/fruits/lime/lime-tree-leaf-drop-why-a-lime-tree-is-losing-leaves.htm
It is likely stressed, either from heat or a watering issue. Normally it is caused by letting the soil get too dry. Citrus trees are funny, because they hold onto their leaves when they are under watered and then drop the leaves when water returns. You need to keep plant evenly watered at all times, especially those in containers, to avoid this.

How do I make my fruit on lemon tree more juicy? When I cut them, they are dry.
Lemons and limes are similar in their growing conditions and suffer from many of the same afflictions. Therefore, the information in this article should help, as it would apply to lemons as well: https://www.gardeningknowhow.com/edible/fruits/lime/dry-lime-fruit-what-causes-dry-limes.htm
When are the lemons ripe enough to pick?
Lemons are ripe and ready to pick once they have completely turned yellow. However, slightly green-yellow ones can still be picked and will normally ripen off the tree, provided they are large enough. They should also be somewhat heavy feeling and hard with a ‘glossy’ look to them. If it’s kind of squishy, you’ve waited too long. The lemon should also be about 2-3 inches in diameter.
Although I bought my lemon plants from a nursery more than 4 1/2 yrs ago and am providing regular fertilizers, water, etc. , they have yet to flower/bear fruit. I am very distressed. Please help.
I would try giving it some phosphorus rich fertilizer, like bone meal. If it is lacking phosphorus, it will not be able to produce blossoms (which means no fruit.)
The requirements for lemons are very similar to that of limes. If you have not read it yet, this article may also be helpful: https://www.gardeningknowhow.com/edible/fruits/lime/reasons-and-fixes-for-lime-tree-not-producing-blossoms-or-fruit.htm
Recently, a lot of wood ash had been spread around my lemon tree and lime tree, and now both trees are looking like they are on their way out. Leaves on both trees are drying up and no lemons or limes on the trees. Can I still save these trees somehow?
You can try flushing the soil around the trees with water to help dilute the excessive nitrogen. In the future, you may want to consider composting the ashes first before using them around plants to avoid problems like this.

I keep it indoors in the winter and in a sunny area outside once the weather stablizes. There's plenty of bees and butterflies, the soil is kept moist and I use Miracle Grow fertilizer.
