I'm starting to see deformed leaves on some but not all my citrus trees, consistent with citrus leaf miner. Apart from it being unsightly is it actually going to damage the plant in some way? The one I'm most concerned by is the kaffir lime given that it is the leaves that I harvest. If it only makes it ugly but doesn't affect the overall plant health then I'm just going to ignore it. If is is weakening the plants - what do I do about it? It does seem to be more marked on the trees that have grass under them so I'm busy sheet mulching to control the grass. Will it become less of a problem as time passes and the system matures more?
