I always top water to remove any salts and oxygenate the roots…

Bottom watering doesn’t reduce rot just increases efficiency of mass watering via capillary wicking. Very useful in commercial growing and hazano who is a great grower on here uses it with his seedlings… can’t remember if he also uses it with adults. Many large scale growers also use this to water their plants.

There are pros and cons with every system. If you dive deeper into plant behavior you will actually see it doesn’t matter since plants are smart enough to adapt and make use of situation.

Reason I top water is in nature rain always top waters… most plants will not reach underwater reserves. I’m sure some may actually only get bottom watered in nature depending on where they germinate but most do not.

I once made a remark to a speaker who advised bottom watering for a certain genus that "it doesn't rain upwards in S. America. :D

Really it can depend whether you are an ardent shower or just a general collector. Some of the shows people tend to water from below since it does not remove the wool from the top of the plant, or risk staining it. Whereas in habitat wind or rain removes the loose wool and so does top watering over the plant.

We once visited a keen show person and one of our party seeing a woolly cactus said "I know how to get rid of all that old wool" and gave it a good hard blow. The owner nearly went ape as he had bottom watered in order to leave all the loose wool on the top over the years for showing purposes since it produced a nice woolly crown.

There are of course three ways to water. The first is water right over the top, provided it is clean water, but if it contains fertiliser it can stain the plant wool on the areoles.

The second is watering into the top of the pot, largely missing the plant and that helps to flush out the salts, just as with top watering as LateBloomer says. However it can sometimes splash dirt on the plant if a woolly plant, or with the white tight spined little Mammilaria's etc can pull dirty water up the spination through capillary attraction. In those cases a reasonable top dressing gravel layer can help to stop that.

The third is bottom watering, but if you regularly do this you either need to periodically repot or flush out the pot occasionally watering in the top of the pot as with the second method mentioned.

The choice is yours since people grow their plants successfully by all three methods.

Love your insights and confess my little lazy with the bottom watering method.

Thank you both for sharing your experience your opinions with a newbie like me.
