Have shower...Water garden

Step 6 Water channel

Lay a length of roof guttering in your garden. I found it easier for Step 7 that involves drilling holes to have the guttering with the flat back side facing the front. As you can see in the first picture it should sit partially over the sunken pots. When I did this I tried to hide the gutter behind my plants. Eventually when the plants grew so much I couldn't see the gutter anymore. Bend up the far end of the guttering so that the water won't run out. Or if you're fancy you could put an end piece on it. Keep your ears open for anyone who is getting new gutters. There should be old lengths with no holes as long as your garden. That's how I got mine. Use what you have. If you have 150mm-6 inch wide PVC pipe, you could use that instead.
