Other Considerations for Outdoor Cacti

Pot Size

When choosing a pot for your outdoor cactus, it's important to consider how large the plant will grow. Most cacti prefer tight spaces and should be planted in pots that are slightly smaller than their rootball. However, larger species like the saguaro cactus require much larger pots to accommodate their size.

Soil Type

Cacti require well-draining soil to prevent root rot. A mix of sand, perlite, and cactus potting soil is ideal for outdoor cacti. Avoid using regular potting soil, as it holds too much moisture and can cause the roots to rot.

Sun Exposure

Most cacti prefer full sun and can tolerate temperatures up to 100 degrees Fahrenheit. However, some species, like the Christmas cactus, prefer partial shade and cooler temperatures. Make sure to research the specific needs of your cactus before placing it in an outdoor pot.
