I have some Agonis flexuosa ‘Nana’ bushes that have been in for about 10 yrs, and this year they have died off due to red spider mites. I have just trimmed back the bushes hoping for some new growth. They are in a sunny position facing west (live in Perth, WA). Is there anything else I can do?

I would recommend spraying the plant with neem oil. We have found it to be very effective against pests and it is safe for humans and pets plus it will not kill beneficial bugs. Here is more information: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm
