How to Grow the Ice Plant

The ice plant (Delosperma sp p.) is a remarkable and visually captivating ground cover that thrives in arid and sunny environments. Known for its unique appearance and ability to withstand harsh conditions, the ice plant is a popular choice for water-wise landscaping and adding vibrant colors to gardens. If you’re looking to cultivate this resilient and beautiful plant, this comprehensive guide will walk you through the steps of growing the ice plant successfully.

Understanding the Ice Plant

The ice plant gets its name from the glistening appearance of its succulent leaves, which resemble dew-covered ice crystals. Native to South Africa, this plant belongs to the Aizoaceae family and has evolved to thrive in arid and coastal regions, making it an ideal choice for xeriscaping and drought-tolerant gardens.

Choosing the Right Variety

There are several species and cultivars of ice plants, each with unique color variations and growth habits. Some popular varieties include Delosperma cooperi (purple ice plant), Delosperma nubigenum (yellow ice plant), and Delosperma ‘Fire Spinner’ (orange and red hues). Choose a variety that suits your color preferences and growing conditions.

Planting and Growing

1. Location

The key to successfully growing ice plants is providing them with plenty of sunlight. These plants thrive in full sun to light shade, so choose a location with at least 6 hours of direct sunlight per day.

2. Soil Preparation

Ice plants prefer well-draining soil. If your soil is heavy or clay-like, consider amending it with sand, gravel, or other materials to improve drainage.

3. Planting Time

Plant ice seeds or young seedlings in the spring or fall when temperatures are mild. Avoid planting during extreme heat or cold.

4. Spacing

When planting ice plants, space them around 12 to 18 inches apart to allow room for their spreading growth habit.

5. Watering

While ice plants are drought-tolerant, they do require regular watering during their establishment period. Once established, water them sparingly, allowing the soil to dry out between waterings.

6. Mulching

Applying a layer of mulch around the plants can help retain soil moisture and suppress weeds. However, avoid placing mulch directly against the plant stems.

7. Fertilization

Ice plants generally don’t require heavy fertilization. A light application of a balanced, slow-release fertilizer in the spring can provide the necessary nutrients.

Care and Maintenance

1. Pruning

Ice plants benefit from occasional pruning to remove dead or faded flowers. This encourages new growth and prolongs the blooming period.

2. Winter Care

In colder climates, ice plants may need some protection during the winter months. Consider covering them with a light layer of straw or using frost cloth if frost or freezing temperatures are expected.

3. Propagation

Ice plants can be propagated through seeds or cuttings. Collect seeds from the plant after flowering and sow them in well-draining soil. Cuttings can be taken from healthy stems and rooted in a suitable medium.

Conclusion

The ice plant is a striking and resilient ground cover that offers both visual appeal and water-saving benefits. By following these planting and care guidelines, you can successfully cultivate ice plants and create a vibrant and drought-tolerant landscape. Whether you’re adorning garden beds, rock gardens, or containers, the ice plant’s dazzling display of colors and easy maintenance make it a valuable addition to any gardening endeavor.
