Cactus Plant in a Pot:
How to Care for Your Container Plant

Updated: May 19, 2023

Cactus plants are great additions to any home, but they can be especially charming when planted in a pot. Not only do they add a touch of green to your interior decor, but they’re also incredibly low-maintenance plants that can survive in almost any environment. Here’s a guide on how to care for your cactus plant in a pot.

Choosing the Right Pot

The first step in caring for your cactus plant is choosing the right pot. A good cactus pot should have drainage holes at the bottom to prevent water from accumulating and causing root rot. Additionally, it’s essential to choose a pot that’s slightly larger than the cactus itself so that it has ample room to grow.

Soil Mix

Cactus plants thrive in well-draining soil with plenty of grit and sand mixed in. You can purchase premade cactus soil mixes, or you can create your own by mixing equal parts of perlite, sand, and potting soil. Avoid using heavy garden soil or compost, as these can retain too much moisture and lead to root rot.

Watering

One of the biggest mistakes people make when caring for their cactus plant is overwatering. Cacti are desert plants that are used to living in dry environments with little water. It’s best to wait until the soil is completely dry before watering your cactus again. In general, you should aim to water your cactus about once every two weeks, but this can vary depending on the humidity levels in your home and the size of your pot.

Light

Cacti love bright, direct sunlight, so it’s essential to place your pot near a window where it can soak up plenty of rays. However, be careful not to leave your cactus in direct sunlight for too long, as this can scorch its leaves. If you notice that your cactus is starting to turn yellow or brown, it may be getting too much light.

Temperature

Cacti are typically hardy plants that can survive in a wide range of temperatures. However, they prefer warm temperatures between 70-90 degrees Fahrenheit during the day and cooler temperatures between 50-55 degrees Fahrenheit at night.

Fertilizer

Cacti don’t require much fertilizer, but you can give them a boost by feeding them with a cactus-specific fertilizer once per month during the growing season (spring and summer). Avoid fertilizing during the winter months when your cactus is dormant.

Common Issues

Even with proper care, your cactus plant may encounter some issues along the way. Here are some of the most common problems and how to address them:

  • Root Rot: If you notice that your cactus is turning yellow or brown and its leaves are starting to fall off, it may be suffering from root rot caused by overwatering. To address this issue, remove the plant from its pot and inspect the roots. Trim away any rotten or diseased roots and replant the cactus in fresh soil.
  • Pests: Cacti are relatively pest-resistant, but they can still fall victim to mealybugs or spider mites. If you notice any signs of infestation (such as white cottony spots or webbing), wipe down the affected areas with rubbing alcohol and move the plant away from other plants to prevent further spread.
  • Sunburn: If you notice that your cactus is developing brown or black spots on its leaves, it may be getting too much direct sunlight. Move the plant away from the window or provide some shade with a sheer curtain.

FAQ

Q: Can I keep my cactus outside?

A: Yes! Cacti are outdoor plants and will thrive in bright sunlight and warm temperatures.

Q: Can I use regular potting soil for my cactus?

A: No, regular potting soil is too heavy and retains too much moisture for a cactus plant. It’s best to use a well-draining soil mix with grit and sand mixed in.

Q: How often should I fertilize my cactus?

A: Cacti only need fertilizer once per month during the growing season (spring and summer). Avoid fertilizing during the winter months when your plant is dormant.

Q: What kind of pot should I use for my cactus?

A: Choose a pot with drainage holes at the bottom to prevent water from accumulating and causing root rot. Additionally, choose a pot that’s slightly larger than the cactus itself so that it has ample room to grow.

Q: Can I propagate my cactus from cuttings?

A: Yes! Cacti are easy to propagate by taking cuttings from healthy plants and allowing them to dry out for a few days before planting them in fresh soil.
