What is eating my mums?

These include thrips, four-lined plant bugs, tarnished plant bugs, spittlebugs, stem borers, caterpillars and beetles. Like other pests, they feed on mums and leave spots as they ruin foliage and flowers.

Some mum species are termed deer-resistant, but this only means that they are more likely to grow back after being nibbled.
