What is going on everyone? Welcome back to the Epic Gardening Podcast. My name's Kevin. Today we're going to talk about

0:07.2

Using an ancient method. This would be the oya the clay pot that you fill up and sub-irrigate your garden.

0:17.0

So there are certainly commercial products, I believe grow oya is the one that I've used in the past.

0:22.4

Really great product, but you can also

0:24.6

DIY an oya out of just a couple terracotta pots. But first of all, let's go ahead and

0:29.7

talk about what it is at a high level and then why you would actually want to use this in your

0:34.8

garden. So it is an ancient irrigation technique and it relies on the fact that terracotta clay is

0:42.1

porous if it's unglazed, which back in the day the technology wasn't even

available to glaze it and so that's what they were doing.

1:21.0

then from there you will cover it up with soil and pretty much that's it.

1:27.2

So what ends up happening is water will seep out through the terracotta clay into the surrounding soil and then as that

1:35.0

soil if it is not already extremely moist it will wick outwards in a spherical

pattern underneath the soil.

1:43.6

Now that only happens for a short period of time

1:46.6

because after all of the soil has enough water in it

1:50.4

it will stop pulling via capillary actions so you'll have

oftentimes when you first put the oia in it will wick out like crazy and you'll need
