2 weeks in sandy ground of South Florida. Do these plants need watering every day or only when newly planted? In clusters of 3 plants 1 or 2 wilt and the others look great until I water them and all look good.
Persian Shield does do best in a container planting.
It does prefer well draining soil, a very sandy planting area may be difficult to grow in.
Regular watering is needed to keep them from wilting. In hot weather you may need to water several times a day.
Here is a link to refresh you on the care requirements.
