The latest on lotus: it needs water but also fears water
The lotus is an aquatic plant and cannot survive without water. "Fearing water" means that if the water level is too high, it will struggle to bloom, or even the whole plant will suffer; because varieties differ, their requirements for water depth also differ. For example, the red lotus growing in Wuhan East Lake, at a water depth of 1.5 m, shows only a few floating leaves, and the standing leaves are all submerged in the water; without standing leaves it cannot bloom. If the standing leaves are submerged for more than 10 days, there is a risk of drowning; even if submerged for 3~5 days, although it can still maintain survival, it will not bloom easily that year.
