Watering: During the growing season, water thoroughly but let the soil dry out completely before watering again. Never let the container sit in a saucer of water. Suspend watering in winter.
Fertilizing: E. 'Blaze' will benefit from fertilization during the growing season. Apply a water-soluble fertilizer. Suspend feeding during the winter when the plant goes dormant.
Repotting: Repot as needed, preferably in late winter or early spring. Choose a slightly larger container with drainage holes at the bottom. Make sure the soil is dry before repotting.
