Take One Home
- Give Neoporteria cachitaensis violet plenty of full sun. Eight hours or more of direct sunlight a day is ideal but at a minimum these plants should be provided with at least five hours.
- If you are growing them indoors, a south-facing windowsill is ideal.
- These cacti thrive in warm temperatures and low humidity. They will thrive in temperatures above 70 ºF.
- They are cold intolerant. Move them inside when temperatures drop below 40 ºF.
- Neoporteria cachitaensis violet are extremely drought tolerant. Always allow the soil to dry out completely in between waterings. When you do water, soak the soil thoroughly.
- If you are unsure whether or not the soil is dry, wait a few days before watering. It is much better to underwater than over water. Excessive moisture can quickly lead to root rot.
- Water less frequently in the winter, every month to month and a half.
- These plants prefer a gritty, sharply draining mix. Use cactus soil or amend regular potting mix with sand and fine pumice up to 50% to improve texture and drainage. We don’t want this soil to retain water.
- In desert climates these plants can be potted directly in the earth and grown outdoors year round.
- During the warm season Neoporteria cachitaensis violet may produce a cluster of pink flowers at the crown.
- Neoporteria cachitaensis violet thrive in poor soils. Fertilization is not required but a limited application could boost growth in the summer months.
- Feed once during the growing season with cacti and succulent fertilizer. Dilute twice as much as the bottle suggests.
- These plants are typically propagated from seeds.
- Grafting is an option for keeping plants alive that have been infected by root rot. Use a clean, sharp blade to sever the infected potion of the trunk. Place the freshly cut trunk on a freshly-cut stalk cactus. Secure with rubber bands and allow the two cacti to fuse together.
- Keep an eye out for red spiders and mealy bugs, both of which can be rubbed off or treated with diluted neem oil.
- Root rot can easily occur if the plant is overwatered, kept in a poorly aerated space, or not provided proper drainage.
Maintenance (pruning, legginess, repotting)
- These hardy plants require very little maintenance. Container grown cacti prefer to be rootbound, so repotting should be necessary only once every two years. Repot into a planter 2” larger in diameter to give the plant plenty of room to continue growing.
- Neoporteria cachitaensis violet have no known toxicity to humans or animals. Spines are sharp so it is advisable to keep out of reach of pets and small children.
