Why are we still discussing how fast the water drains. You originally suggest using the shards to keep the soil from plugging the drain hole, not so the water would drain faster.Ok, I get it. But honestly, isn't that sort of like mountains to mole hills?
I actually water my plants from the bottom as they seem to do so much better for me that way.
Of course that also begs to wonder how the water knows it is soil and when to slow down. If you change the pots medium from soil to sand or straw would you confuse the water? Is there an intelligence test for the water? Some days I think my water gets a bit confused. Perhaps it just didn't get a good nights sleep, I believe I've even caught it napping on the job once or twice.![]()
I then explained that the problem with shards isn't that they won't keep the soil from plugging the drainage hole. The problem is with the drainage rate, a different problem. So, there is no need to start defending the use of shards to speed up drainage. You seemed to mean that the shards actually do keep the soil from plugging up the holes. Is that what you meant?I know that one site said the following was bogus and not true but I swear it works.
1. Putting broken shards in the bottom of a pot to make an airy area around the drain hole helps to prevent the dirt from sifting down and clogging the drain. I've always done it and have never had water logged potted plants from not being able to drain properly.
2. You can crush them further to mix into your soil. Helps to retain moisture.
