What can be done and how can you help?
If you notice an infection, contact your community manager who will contact your landscape company to help control the problem; they should then remove and destroy plants with symptoms of infection.
Plants should be pruned regularly and weeds removed to improve air circulation and reduce fungal growth.
Overhead irrigation should be avoided during cool weather.
Consider watering in the morning hours so that plants dry during the day.
Do not over- or under-fertilize as it may increase the chances of infection.
Consider other host plants as ground covers when replacing diseased ice plants.
