The pink iceplant succulents is quite forgiving in regards to pH levels. They can do well from a mildly acidic level of 6.1 to a mildly alkaline level of 6.8.

Grooming & Maintenance

Because these plants ramble and spread, periodic trimming helps prevent plants from taking over smaller garden settings.
