Medium_img_2853 Dying Westringia

I have a second Westringia that is dying, I removed the first one last year,not sure if it is root rot or curl grub
They are in a rockery with builders plastic under the stones
For which I'm going to replace with weed mat, wondering if the soil has gone sour??
I have other Westringia's close by that are doing fine
Would these benefit with a spray of Yates root rot?
What should I look for when I pull the dying Westringia out?

Answer: Thank you for contacting Yates.

The most likely cause of the dieback of matured Wistrigia is soil related. I would suggest starting with checking soil pH and soil structure. When digging the dead plant out, double check the roots and soil, see if there are any soil born disease reflecting on roots or pests in soil.

Before replanting, I suggest improving soil by digging in some Yates Dynamic Lifter Soil Improver & Plant Fertiliser, which is a manure based, certified organic fertiliser, and will provide all the nutrients (nitrogen, potassium and phosphorus) for your plants need to grow and thrive.

As for the product Yates Anti Rot, it is only registered to apply on plant foliage instead of soil drenching.

Hope this helps and happy gardening.

Best Regards,
Yates Horticulturist
