I am unsure if this is an issue at the moment but i have a 3 month old lemon tree and have noticed that little black ants are climbing all over it ?

Will they harm the plant in any way and why would they do this ?

Does anyone have any thoughts

Check your lemon tree leaves for scale on the underside of the leaves. Some scale insects secrete a sticky substance that is attractive to ants. If you see the scales on the leaves, spray the leaves with White Oil.

A good way to stop ants climbing your fruit trees ...and lemons in particular....is to put a ring about 6cm wide of vaseline around the stem halfway btween the ground and the first branches...the ants wont walk over it and it prevents them carrying disease and scale onto your tree.The ants eat the sweet secretions of the scale and carry them from tree to tree in a symbiotic relationship.
