Echinopsis calochlora

Native to dry regions, the Lemon Barrel Cactus does best in full sun, since its natural habitat has intense sunlight and very little shade. It can also tolerate partial sun, giving it some flexibility in where it grows.

The Lemon Barrel Cactus does best in warm conditions and needs higher temperatures during the growing season to support growth and metabolic processes. It favors plenty of sunlight, proper moisture, and good airflow. However, it is vulnerable to harm from very low temperatures and from overwatering. It’s also important to maintain balance and avoid excessively high heat and overly dry conditions.

This plant prefers dry conditions, so don't mist it. However, watering it less often can also thrive in higher humidity.

For Lemon Barrel Cactus, a light application of fertilizer once or twice a year during the growing season is enough. Do not fertilize in winter or in summer when the plant is dormant. Cut back on feeding for recently repotted plants and wait a couple of months after repotting before applying fertilizer. Fertilizing helps maintain healthy growth and promotes flowering.

Repot the Lemon Barrel Cactus in spring or summer, choosing a pot slightly larger than the current one that has good drainage. Use a sandy or gritty cactus mix that drains well. Handle the plant carefully to avoid its spines. Let the cactus dry out before repotting to help prevent root rot. After repotting, wait a week before watering so the roots can heal.
