Cactus plants can be divided into terrestrial (Terrestrial) species and epiphyte species according to their ecology
(1) Terrestrial species: native to the tropical or subtropical arid desert and semi desert areas of America, it generally enjoys strong sunlight and dry environment, so it grows slowly. From the morphological point of view, there are cacti, cacti, cacti, cacti and cactus mountain, a wide variety. There are only 400 species of cactus.
(2) Epiphyte: native to tropical rainforest or coastal humid areas, attached to shady trees or rocks, like warm, humid and shaded environment all year round. Crab claw orchid, Lingjian lotus, Epiphyllum and Tianchi (trigonometry arrow) are common epiphytic cactus flowers. They need more water than terrestrial species, so they grow faster. Because they need more water, they should be watered properly in the growth period, but in the dormancy period, they should keep half dry. They prefer slightly acid soil with strong drainage and water retention, while terrestrial species prefer calcareous alkaline soil with good drainage and aeration.
