A combination of small slow-growing plants (with similar growing needs) arranged attractively in a shallow dish or container creates a mini-garden, often referred to as a dish garden. These easy-to-care-for gardens range in size from a tiny saucer to a large shallow bowl with intricate designs. Many prefer to grow cactus gardens in terra cotta or natural stone, but dish gardens are not limited to cacti and succulents. Miniature tropical plants make delightful gardens as well. Although maintaining the correct level of moisture may pose a challenge, it should not prevent you from growing a dish garden.
Review the growing needs of your specific plants. Cacti and succulents require little water, whereas tropical or semi-tropical plants may require moist soil. You can find this information on the plant identification tag when you purchase the seedlings.
Apply water at room temperature. Cold water shocks young roots and may cause stress to plants. Allow tap water to sit for 24 hours to remove chlorine before using to water plants.
Add water slowly. For small cacti gardens, 1 or 2 tsp. may be all that is needed. For tropical plants, add a small amount of water and test the soil with your fingers. Soil should be moist, but not soggy. As a general rule, add no more than one quarter to one third the volume of the container.
Check the soil often and water if plants show signs of wilt.
