Current Live Stoners Gossip June/July/August 2017

[Master_gRoshi]

There's actually a lot of myth to the old gravel at the bottom of a pot to improve drainage bit. The change in medium will actually create a barrier that can keep water IN the soil until it becomes saturated before any will drain. There's lots-o-stuff round the 'Net about it. Still...another one of those that folks have been doing for eons and getting good plants doing, so your call.

Sounds like a @pop22 myth busters topic!

Yeah not gravel but river rock. These stones are smooth and drain just fine . Gravel would cake up and harden id I imagine . No good.

Also a lot of gravel has cement that could also contribute to this. Natural river Rock is beautifully eroded and natural and free. I see no myth but would like to read anything you had with solid points .

I just find it hard to see any science in what the "myth" actually holds . All seems basic and straight forward .

Yes, the stones themselves will drain any water that gets there just fine. The myth part comes in when this is done to improve the drainage in the soil above the rocks. Water does not flow from the less coarse soil to the more coarse rocks as easy as intuition might imply. Think capillary action sucking water UP into the soil against gravity. The water tends to prefer to spread out in the soil. Until the medium is saturated, it will continue to spread out and stay in the soil, so putting rocks underneath does not improve that. It allows you to use less soil to fill the pot up, and might help with keeping medium from leaking out the drain holes in the bottom. But it does little more than that.

Most of the places I've read are different gardening sites around the 'Net and I don't want to link offsite since it could get me tossed on the naughty step. The link to pop's thread on it a couple posts back has some good info to start with, though.

We're not here to prove you wrong we're here to educate . That's why I ask so many questions . There's stuff here that you won't learn in university or college .
