Medium_img_9249 Westringia dying, wilting and no leaves at base. Caterpillar in root but not curl grub. Would this be cause?

The Westringia looks to be all but dead except for green leaves at top. I'm not sure if it's root rot, because I've checked the roots to see if there is evidence. The caterpillar is thin, and has two black stripes lengthways, and curls up

Answer: Hi Jasmine,

Thank you for contacting Yates.

Root rot can occur in the westringias readily but the dieback is shown from the tips not the base there.

It is more likely that your lovely hedge has been eaten by a caterpillar or army worm. These can be pesky and generally cause a fair amount of damage in the lawn but are known to attack plants as well. To combat this pest we recommend using Yates Dipel.

The only real downside here is that once damaged, brown sections of the westringa rarely recover. If there is still some green growth at the base try and encourage further growth from these sections with a regular feed of Yates Dynamic Lifter Soil Improver and Plant Fertiliser.

Kind regards
