I am very new to gardening and have a lemon tree (not sure what kind) that is very special to me as it was a gift from someone that planted it as a seed. I recently repotted it because I saw that it was growing so tall. While I was looking online for more tips on caring for it I came across your website and learnt about sucker branches. I'm worried that the large branch on my lemon plant may in fact be a lemon plant. I have attached a picture. Can you tell me if this is a sucker branch and if so what I should do about it? Thanks!!
It is fine to leave all the branches that your lemon has in place. Suckers typically grow right from the base of the tree at the soil- you should cut those off.
Also, I would recommend repotting your lemon tree in a smaller pot. The issue with a small plant in a large pot is that the soil holds onto water too long, which can damage your plant's roots. Once your tree is a few more years old, you can move up to a larger pot. This article shows a citrus tree that is in a more appropriate pot for its size:

Some of the leaves are showing blackish patches which look like a mould of some kind. What can I do?
This is likely sooty mold, a fungus that grows on honeydew, a sticky substance left by certain insects. The best way to control it is to control the insects:

My lemon plant is about 3.5 inches tall and has developed 9 leaves. When will it blossom and bear fruit?
The good news is that your lemon plant looks very sturdy and healthy.
The bad news is that you've got something of a wait ahead of you. Lemon trees grown from seed often take about 15 years before they actually produce lemons.
In the meantime, though, you have a great looking plant with wonderful-smelling leaves. You can read more about caring for lemons in containers here: https://www.gardeningknowhow.com/edible/fruits/lemons/growing-lemon-trees-containers.htm
My lemon tree has produced excellent lemons for years. The current lemons are much smaller and splitting ? Thanks Gayle
Weather changes and extremes can cause the Lemons to split. This is not anything that you can control.
Heavy rains during warm spells can also cause fruit to split.
If you also fail to water, then water heavy, the results will also be the same.
Soil should be a constantly moist but never soggy.
Dry weather spells followed by high humidity can also cause this issue.
Mulching the tree will help the tree moderate it's moisture levels.
Small fruit can be due to lack of pollination and nutrient levels.
Follow a good fertilizer schedule.

tree seven years old- leafs are turning yellow, lot of blooms on it-am in the south and tree has always done well
Leaves could be turning yellow due to temperature fluctuations, watering issues, pests, disease or nutritional deficiencies.
Closer examination of the leaves, branches and soil conditions should be done to rule out and help pinpoint the exact cause of the leaf drop.
