Plant your blue dwarf aloe in a container with drainage holes. Use a sandy loam potting soil, or a potting soil intended for cacti. First, fill the container halfway with potting soil. Place the aloe in the container, wearing gardening gloves to protect your hand from the spines. Fill in the container with soil, packing it around the plant roots. Water the plant to compact the soil.
Place your aloe plant where it can receive bright natural light, such as near a south-facing window. If you don't have adequate natural light, supplement with a fluorescent plant light. If using a fluorescent light, keep it on for 14 to 16 hours a day, and position it 6 to 12 inches above the pant.
Water your aloe sparingly. Like cacti, these need little water. Water the plant once a month in the water and as much as every week in the summer. Always let the soil dry out fully before watering again and add water until liquid flows out the drainage holes in the bottom.
Fertilize aloe in the spring, when growth resumes. Use houseplant fertilizer diluted to half strength. If you wish, fertilize again in the summer.
Move your plant outdoors in the spring and summer, when all danger of frost has passed. Care for your plant outdoors, where it can receive full sun, until fall frosts threaten to harm the aloe. This aloe can take a few degrees of frost occasionally, but it's not good for the plant. Gardeners with frost-free winters can care for the plant outdoors year-round.
