Cactus and Succulent Care Tips

Perhaps you've noticed the growing popularity of cacti and succulents in garden centers. With the easy growing requirements and distinctive beauty of these plants, more people are choosing to grow them as indoor houseplants and in outdoor landscapes. The growing rules for cacti and succulents are surprisingly simple. Even if you have a brown thumb, you will probably be able to grow a succulent garden successfully.

Watering

The typical belief about a cactus or succulent garden needing only very minimal amounts of water is not completely accurate. These plants can survive with little water, but they probably won't thrive.

• For best results, water a cactus or succulent about once per week until the soil is thoroughly soaked.
• Use rainwater if possible.
• Fertilize with a balanced fertilizer once per week during the growing season.
• When the growing season ends, stop fertilizing and space out the watering to the point where you just keep the leaves from shriveling.

Light

A cactus or succulent garden will thrive in bright light, but avoid direct sunlight and high temperatures. The amount of light needed will depend on the plant species. You can usually figure out whether your cactus or succulent is happy by observing it.

• If the leaves look bleached out or are turning strange colors, the plant is probably getting too much light.
• If a plant seems to be stretching toward a light source, it probably needs more light.
• Slight stretching toward a light source is normal, and you can avoid a misshapen plant by rotating the pot regularly.

Potting

The type of cactus or succulent you have will determine the best style of pot. Some cacti have fibrous roots that will demand a shallow pot with a large diameter. Other plants have large root systems that require large and deep pots.

• Pot materials may be clay, ceramic, or plastic.
• The main feature to ensure that any pot has is adequate drainage. Make sure that your pot has drainage holes in the bottom, or drill them yourself before planting.
• Soil for a cactus or succulent needs to drain well. A premixed succulent potting media will usually have horticultural-grade sand or grit added to it.
• You can also make your own potting media by combining one part compost, one part horticultural sand, and one part grit. Try horticultural pumice or pearlite to make up the grit component.
• Repot cacti and succulents once each year to ensure that the plants have fresh soil and enough growing room. When roots begin encroaching on the sides of the pot or through the drainage holes, it's time to repot.
• To repot a plant, wearing gloves to protect yourself from spines and sap, loosen the soil gently to remove the plant from the pot. Remove as much old soil from the roots as possible without damaging them. If you see dead areas of roots, cut them away. Then, place the plant into a larger pot with fresh potting media.
• After repotting, wait a week or two before watering the plant for the first time. Keep it out of direct sunlight for the first two weeks as well.

Pests

Cacti and succulents are at risk for pest infestations. Some pests will kill a plant, while others will just be a nuisance to you.

• Mealybugs are a common pest that can lead to poor growth. If the infestation is minor, you can kill them with a cotton swab dipped in rubbing alcohol. You may need to soak the roots and repot if mealybugs are attacking the roots.
• Spider mites will make white webs on the plants. Over time, you'll know you have spider mites if you see brown spots on the plants. Try watering from overhead or misting the plants to get rid of spider mites.
• Scale will look like brown spots on the plants as they consume the sap. Treat scale in the same way you'd treat mealybugs.
• Fungus gnats are small, black flies that may damage your plants. Avoid using soil with peat moss to avoid fungus gnats.
