How to Prune a Lemon Tree
When you are ready to prune your lemon tree, ensure the cutting tools you use are sharp and clean. If they are blunt, you will be left with roughly cut branches, which can attract pests.

Citrus trees usually have strong wood, but they also have thin barks. For this reason, you should prune with the blade facing the tree to avoid chipping off the bark.
Your aim should be to preserve the branch collar; this is the area around the base of a large branch with wrinkled-looking bark.
This area is also known as the “branch defense zone,” filled with cells that trigger the callus tissue (tree wound), which grows and covers a cut to prevent tree decay.
For branches more significant than an inch, be advised to use the three-cut system to avoid damaging the tree bark.
Proceed with an angled cut, about 12 inches out from the branch union, then cut 1/3rd deep into the branch on the other side (the undercut).
Next is to move a couple of inches above the length of the branch and cut from the top, severing the unit in the process.
Ensure you do not yearly prune more than a third of the entire tree. Start pruning your lemon tree in its second year so you can train it exactly how you want it to grow.

You can use your pruning saw to cut branches more significantly than that.
Remove any root suckers you come across that are growing below the graft union. Use bypass pruners for this, and make the cut as low to the soil level as possible.
You can remove suckers anytime throughout the growing season.
If you have more than one potted lemon tree, then be sure to disinfect your cutting tools after using them on the first one before you use them to trim the next one. Diseases can be passed from one tree to another via cutting tools, so disinfecting them is necessary insurance.
Rubbing and crossing branches should be removed so that sunlight can reach the tree’s center.
For potted dwarf lemon trees, the winter season is the best time to prune them. This should be after the tree has finished fruiting for the season and before any new growth commences.
