Cold Hardy Cacti: Desert Beauties for Northern Climates
Introduction
Cacti are often associated with hot, dry climates, but surprisingly, there are many species that can tolerate cold weather. These cold hardy cacti are a great choice for gardeners in northern climates who want to add a touch of the desert to their landscape.
About Cold Resistant Cactus
Cold hardy cacti have evolved unique adaptations that allow them to survive in freezing temperatures. These adaptations include:
- Thick, waxy skin: This helps to protect the cactus from moisture loss and freezing.
- Prominent spines: Spines help to conserve moisture, provide shade, and protect the cactus from freezing.
- Ability to drain moisture: When temperatures drop, cold hardy cacti drain moisture from their pads and leaves, which helps to prevent freezing damage.
What Cacti are Cold Hardy?
There are many different species of cold hardy cacti, including:
- Prickly pear: This is one of the most common cold hardy cacti. It has flat, paddle-shaped pads and produces edible fruit.
- Beehive cactus: This cactus is known for its spherical shape and dense spines.
- Claret Cup cactus: This cactus has showy, cup-shaped flowers that bloom in the spring.
- Cholla: This cactus has long, slender stems that are covered in spines.
- Pineapple cactus: This cactus has a pineapple-shaped body and produces edible fruit.
- Old Man cactus: This cactus has a distinctive, woolly appearance.
- Orange Snowball cactus: This cactus has bright orange flowers that bloom in the spring.
- Barrel cactus: This cactus has a large, barrel-shaped body and can store water for long periods of time.
Growing Cold Weather Cactus
Cold weather cacti are relatively easy to grow. They prefer well-draining soil and full sun. Water them regularly during the growing season, but allow the soil to dry out completely between waterings. In the fall, reduce watering and stop watering altogether during the winter months.
Tips for Winter Care
Cold hardy cacti go into a dormant state during the winter. During this time, they do not need to be watered. It is important to protect them from freezing temperatures by providing them with shelter. You can do this by covering them with a blanket or moving them to a sheltered location.
Troubleshooting Problems
Cold hardy cacti are generally low-maintenance plants, but they can sometimes develop problems. Some common problems include:
- Root rot: This is caused by overwatering. Allow the soil to dry out completely between waterings.
- Sunburn: This can occur if the cactus is exposed to too much direct sunlight. Gradually increase the amount of sunlight the cactus receives over time.
- Pests: Cold hardy cacti can be susceptible to pests such as aphids and mealybugs. Treat infestations with an appropriate insecticide.
With proper care, cold hardy cacti can thrive in northern climates. These desert beauties will add a unique touch to your landscape and provide you with years of enjoyment.
