My lemon tree has all of a sudden started showing signs of disease. It does have something that looks like aphids on it but they have been there for months and just all of a sudden the leaves are getting brown spots, dropping, and dropping. Could this be from the aphids?
This could definitely be aphids. You will want to spray it with neem oil in the early morning once every few days until there is no more sign of infection. This link will take you to some articles that will help you to making your own pest control: https://www.gardeningknowhow.com/special/organic/

I believe this is a duplicate, and has been answered on the one with the picture.
I noticed the sticky sap on my lemon tree and with further inspection saw scale on the stems and underside of leaves. The tree had alot of blooms which have since died and fallen off. I sprayed the tree well with Neem Oil. It did get rid of the scale, however, now the leaves are drying and falling off. What is going on? What should I do in order to save my tree? Thank you in advance for your advise. G. Piper
You will want to use neem out while there is no direct sun. This is what causes the burning. You have to apply it multiple times, and scrape off as many of the scale as you can. There are many other methods for killing these as well.

Thank you for your reply, however, my question was not answered. I have gotten rid of scale and I did use the neem oil outside on a cloudy and 70 degree temp day. Brought tree back inside for duration of winter and is located by a glass door receiving full light all day. My unanswered question is why are the leaves drying and falling? Normally the plant is producing lemons now but no sign of any although I did have alot of flowers. Should I prune back the tree and if so, how much? My tree is 4 feet in height.
My meyer lemon is now about 4 feet tall but still has only one main branch. How do I get nrpew branches to grow so it becomes fuller and not just tall? I have had it almost two years now and although it looks healthy, it only grows taller and not fuller. Thank you for your help.

I have a Meyers Lemon tree in a very large pot but it is very root bound. Should I cut away the base of the roots and repot it with fresh soil or just leave it potbound?
Spring is a great time to repot-just as the tree is entering it's growing season.
Fill a new pot-1 size larger, 1/4 full with a similar potting soil.
Remove the tree from the old container and examine for roots that may be encircled around the base.
You can cut through these roots with a clean knife to ensure the plant takes up nutrients and water in the new container.
Set the tree in the new pot and adjust the soil so that the top of the root system sits 2 inches below the pot rim.
Fill in the soil around the root system and water throughly and add more soil if needed.

How much space does a Meyer lemon plant in the ground need? Would a Meyer Lemon tree do well grown as an espaliered tree?
You can get by with as little as 10 gallons of soil. So space won't be an issue. These will do just fine as espalier trees. Here is an article for general care of these trees: https://www.gardeningknowhow.com/edible/fruits/lemons/growing-meyer-lemons.htm
Have a 3 year old Meyer lemon tree in a pot which is indoors for the winter. Noticed several budding flowers- should I fertilize now and please recommend what fertilizer to use.
You should only fertilize in spring unless you use a liquid feed. I recommend a granular once per year. There are many on the market made, specifically, for citrus.
It is also worthy to note that they will not be able to produce fruit indoors without supplemental lighting. Even a south facing window will not do, as the light is still filtered a little through the glass.
I recommend at least 200 watts of horticultural grade lighting. I prefer LED as they consume less energy, and produce less heat.
