Q.ice plants dying
My ice plants (which are in full sun and the soil pretty dry) are turning brown (tan) and look like they are dying. Any suggestions? Water once a week on drip system.
I would actually check the soil to see if it is wet consistently, to much water can cause the issues you describe.
Disease or fungus could also be a possibility. Removal of the dead material and then using Neem Oil treatment would be recommended.
Neem Oil acts as both an insecticide and fungicide.
Here are some links for you to refresh you on the care requirements.
