Family : Cactaceae

🏝️ Habitat Conditions

This plant mostly grew in arid desert environments. It has a short growing season and a long dormancy period.

👀 Characteristics details

Most of them have spines, which minimize water loss. As a result, overwatering can easily lead to their death.

🌺 Flower

Most flowers are vibrant and bloom at night. For artificial pollination, it should be done at night.

🌿 Photosynthesis

Most plants in this family use CAM (Crassulacean Acid Metabolism) photosynthesis, typical of desert plants. This means they close their stomata during the day to minimize water loss and perform photosynthesis at night. Therefore, it's best to water them at night. However, they are sensitive to overwatering, so they should be kept in a well-ventilated, dry environment.

🎋 Stem

It has a succulent stem that performs photosynthesis and stores water instead of leaves. At the junction of the stem and spines, there are small spine cushions, called areoles, which protect the growing points. This characteristic distinguishes it from typical succulents.

🪴 Root&Soil

Most have shallow, widely spreading roots. Therefore, they do better in wide, shallow pots rather than deep ones.
