The Cardon Grande cactus starts off as a fat columnar cactus. Younger species are smaller but after many years, this species will grow bigger and taller, and produce its characteristic side arms. Whether in natural surroundings or in a garden, the Cardon Grande is capable of reaching 10 to 15 meters tall with a diameter of 60 centimeter. Not only is this a beautiful plant in its own right, it is extremely fast growing.
A typical healthy Trichocereus terscheckii specimen has 8 to 15 ribs. These ribs also contain small, regularly-spaced bumps on the surface called areoles. These areoles are approximately 2 centimeters in diameter and are 3 to 4 centimeters apart from each other. Each areole contains a set of 10 to 16 yellow spines which are 10 centimeters long.
Cardon Grande also produces large white flowers. These flowers can reach lengths of 15 to 22 centimeters, and widths of 14 centimeters. Each petal can be as long as 8 centimeters. The flowers have tubes with brown, woolly hair.
This species flourishes best in limestone along with good potting material. Requires moderate watering and should be completely drained during summers. Winters need less watering. Sunlight loving, these Cactus should be protected from the harsh sun but afternoon sunlight is good for their growth.
Usually these are outdoor plant, grass lands, landscapes.
For watering cacti, the golden rule is to make sure the soil is completely dry before watering! This will stop the roots from rotting. It is advised to always use a pot with a drainage hole so that excess water can get drained out. If kept in a sunny area, you will need to water it once every week. If it is in a semi shaded or filtered light area, you might need to water it once in 2 weeks.
Cacti like soil that is well aerated and fast draining. You can fertilise the cactus in the summer months when it is in its growing season. During the winters it is best to cut back on any fertiliser and let the plant rest.
