Place the dish garden in an area that receives bright but indirect sunlight. A location near a sunny south-facing window supplies enough light, as does a location with filtered light through a sheer curtain. Direct sunlight can burn and damage the succulent leaves.
Select a location away from cold drafts, such as near open windows, doors or air conditioner vents. Constant cold air damages the succulent plants.
Water the plants when the soil in the dish dries out completely. Provide enough water to moisten the soil but avoid standing water. Most dish gardens don't have drainage holes so careful watering is necessary. If your dish has drainage holes, empty the water from the drip tray after irrigation.
Fertilize once monthly with a soluble low-nitrogen fertilizer. Apply the fertilizer at half the rate recommended on the package. Only fertilize in the spring and summer growing season and stop fertilizer treatments in fall and winter.
