Q.Leaf Damage On Dracaena Marginata

Zone DL10 4BE UK | Bill Norrie added on February 21, 2020 | Answered

Recently we have noticed some damage on otherwise healthy leaves of our Dracaena Marginata which is kept in our conservatory along with other plants. None of the other plants are affected. The damage seems to be confined to the edges of the leaves and looks similar to that when a caterpillar has chewed the leaf. We’ve examined the plant but can’t see any obvious pests. However, we have observed tiny deposits on the affected leaves which, under a magnifying glass, look like tiny bits of ground up ‘vegitation’ – possibly insect faeces ?? We’ve done lots of searching on the internet but so far have drawn a blank…. Wonder if anyone could help identify the cause and possible cure? A photograph of typical leaf damage is attached.

This, certainly, sounds and appears to be insect damage. It could be anything from caterpillars to ants, unfortunately.

There are many broad spectrum insecticides that will work for most things, as long as it is not a spider mite infestation. (It doesn't seem to be)
