3 plant watering methods to get right for lush green leaves and strong roots that are easy to keep alive

You have probably often heard people say at some point that plants should be watered at a certain time. Actually, that is a rather general statement. Because every plant is grown differently, their soil is different too, and the light they receive is different as well, and all of these affect its moisture. Sometimes when it suddenly drops, we can judge by how dry or moist the soil surface is, but if the layer is suddenly very thick, then this method will not work.
I have introduced plant watering methods before, but those were rather general. In fact, different plants need different watering methods. We water plants because we see they are short of water, but here comes the problem: what characteristics must a plant show to prove that it really is short of water? Different plants show it in different ways. Below I list the signs of water shortage in several plants.
Peace lily
When a peace lily is short of water, its signs are very obvious. When it lacks water, its leaves will not turn yellow and drop, but as a whole both its leaves and flowers will wilt. If your peace lily shows this, and we water it within a week, it can still come back to life.
But once it goes beyond a week, it really will die of thirst. So as soon as we find the peace lily's leaves and flowers showing this, we should water it immediately, the sooner the better.
Anthurium
It is still different from the peace lily. If it lacks water, wilting will appear at the tips of the leaves. If we find wilting at the tips of an anthurium, we should water it immediately, without any delay at all. But there is one exception.
If the anthurium we bought is in its original pot, that is, it has never been repotted, then no matter how much water we give it, it is fine, and it will not be drowned. But once we have repotted the anthurium, it no longer has this advantage. Once we find wilting, we must water it immediately. We cannot let it lack water, and we cannot let it be drowned by water either.
Monstera
This plant is very easy to grow, because the monstera's root system is very developed, and its new roots can fill the entire bottom of the pot, so no matter how much water we give it, it can all be absorbed. So this plant is especially suitable for beginners to grow, and there is no fear of it being killed.
Moreover, if a monstera is short of water, it will not show the signs of the two plants above. It will only have a rather dry soil surface, so if we are judging whether a monstera should be watered, we can judge by how dry or moist the soil surface is.
