Whether you're a new plant parent or a seasoned green thumb, adding a cactus to your collection can be a great way to bring beauty and character into your space. Surprisingly low-maintenance, cacti are easy to care for once you know the essentials.
Below, botanist Cecilia Thon and Alfred Palomares, vice president of merchandising share their expert advice for keeping your prickly plants happy and healthy.
1. Give Your Cactus Enough Light
Cacti thrive in direct sunlight, but they don't need too much of it. For optimal growth, place your cactus in the warmest, sunniest corner of your home. A south or west-facing window with a few hours of direct light works best. If natural sunlight is limited, consider using a grow light. Palomares advises keeping cacti away from air conditioner vents or drafty windows, as they prefer warm, dry climates.
2. Give Plants An Outdoor Summer Vacation
Cacti will thrive outdoors during the summer months, especially if you have a sunny patio or yard. Thon recommends giving your cacti an outdoor "vacation" where they can grow more quickly. However, be cautious not to expose them to temperatures below 50°F at night. When transitioning your cactus outside, start with partial shade and gradually increase exposure to direct sunlight to avoid sunburn. If your cactus begins to turn yellow or brown, move it to a cooler spot.
3. Don't Overwater Cacti
One of the most common mistakes in cactus care is overwatering. Cacti store water in their stems and can survive long periods without water, but they still need a good drink every now and then. Palomares advises checking the soil every few weeks. If the first 2 to 3 inches are dry, it's time to water. In summer, you might water every 10–14 days, while in winter, watering may be needed only every 3–4 weeks. If your cactus is wrinkled, it may be dehydrated, and a deep soak will help it plump up again.
4. Use The Right Soil
To keep your cactus healthy, use soil designed for succulents and cacti. Regular potting soil retains too much moisture, which can lead to root rot. Choose a soil mix with more sand and rocks to encourage proper drainage. Also, select a container made of a breathable material like terracotta or ceramic with a drainage hole.
5. Use The Right Fertilizer
Fertilizing your cactus can help promote growth, but it's important to use the right type of fertilizer. Opt for one specifically made for cacti or succulents, which will be lower in nitrogen and higher in phosphorus and potassium. Apply the fertilizer according to the directions, but don't overdo it. Thon suggests fertilizing once in spring and again in summer, but no more than that. Always water your cactus before applying fertilizer to prevent root burn.
6. Choose An Easy Cactus Plant
If you're looking for an easy-to-care-for cactus, the prickly pear is a great option. Thon recommends placing it in a southeast or west-facing window that receives direct sunlight from spring through fall. Other low-maintenance cacti include star cactus, golden barrel cactus, hedgehog cactus, and pincushion cactus.
7. Handle Cacti Safely
Cacti can have sharp spines, so it's important to handle them with care. Always wear protective gloves when repotting or pruning your cactus, or use kitchen tongs for added safety. Wrapping the cactus in a towel or newspaper can also help protect your hands. While cacti are not poisonous, some people may experience allergic reactions from contact with the plant.
By following these tips, you can enjoy a healthy and thriving cactus in your home for years to come.
