Too much water or temperatures below freezing can damage or kill a saguaro cactus.
Too much water. It has been watered too much and grew too fast.
Although there are cacti that live in the rain forest, the average desert cactus will quickly rot and die if too much water is present.
cactus. They have been evolved to survive in environment low in water. if you give it too much water it will start decaying
Desert. Cacti thrive in arid habitats. Too much watering will kill the plant.
A cactus plant disintegrates when it gets too much water, because of its tissues. Its tissues aren't set up to work with continuous or large amounts of water. Instead, they're adapted to get as much of the infrequent and insubstantial amounts of water that they can from a bright, drab, dry, extreme, harsh desert environment. Overwatering and waterlogging cause cactus tissues to blacken, rot, and die.
Yes, both can.
More water or less sunlight may be ways to heal a brown cactus plant.Specifically, a cactus is drought and heat tolerant. But it may turn brown because of too little water. The plant is adapted to water-poor environments. But that does not mean that it has no water needs at all.A cactus plant likewise may turn brown because of too much sunlight. The latter situation is the equivalent of a cactus sunburn. A cactus in fact has a side that adapts to receiving more sunlight than the other. But there is such a thing as overexposure if the sunning lasts too many hours and the light is too harsh.
Of course. Too much anything can kill you, even water.
too much water too little water too much fertiliser not enough fertiliser herbicides amongst other methods
yes, it will kill them
If your cactus is squishy, it has probably been watered too much and is rotting.
