Ice plants do not tolerate extreme cold temperatures and wet soil, so gardeners should plant them in warm climates in areas where the soil stays dry. Ice plants are hardy succulents and require little care or fertilization in the right conditions. The plants thrive in full sun but can also grow in lightly shaded areas.
Ice plants grow best in plant hardiness zones five through nine. Gardeners can grow these plants in pots in colder climates, and bring them indoors in the winter.
Ice plants spread to create a natural groundcover and can be invasive in areas with consistently dry soil. Gardeners can propagate the ice plant by uprooting and dividing the plant, taking cuttings, or by planting seeds. The best time to divide the plant is in the spring, and gardeners can take cuttings any time of the year except winter. When growing ice plants from seed, gardeners should not cover the seeds with soil as they require sunlight to stimulate germination.
Because they are evergreen in warm climates, ice plants can provide groundcover year-round. Each plant can spread 2 to 4 feet and grow to 3 to 6 inches in height. They bloom in the summer and autumn in a variety of colors, including purple, yellow, pink and white, depending on the species.
