Cactus can ward off evil spirits in geomantic omen. The name of this plant contains the word "cactus", which also means peace. The geomantic implication of cactus itself is good, so we should also know that cactus flowering is a good sign.
Cactus need to go through dormancy before it can bloom. During dormancy, nutrients will accumulate, and sometimes it may be difficult to blossom if it is well maintained. The flowering time of cactus is generally the most concentrated in March-May, and the specific flowering time depends on the size and variety of the plant. Generally speaking, cactus needs to be cultivated for two or three years before it can blossom.
