How do you tell what is rootstock on citrus trees?

[#1]

The graft on a citrus tree is usually just above the soil line, often a few centimetres up the main trunk. It might appear as a slight bulge, swollen joint, or a change in bark texture or colour. Any suckers that sprout from the rootstock below this point should be removed.

Rootstock suckers typically grow more vigorously, have large thorns, different leaves, and a more greenish stem. They also don't typically produce any fruit.

If you need to remove rootstock that leaves a large wound, treat it with Steriprune to help protect the tree and prevent infection.

Keep an eye on the area and remove any new suckers that emerge. Regularly check for new growth coming from the rootstock and snip it off. - MitchellMc
