Looking good! Another question – what happens with the water overflow, eg when it rains?May 30, 2010 at 1:29 pm #466933
The depth is shown in the diagram, I did this up to describe the layout of what I was going to do on the cheap at a school garden until their funds arrived. Basically an earthwall (slightly compacted) Inground but still closed Wicking Bed. My beds as you can see use a sleeper on the side, this way I can walk on the sleeper and plant between the bed :), its where I put my beneficial perennials. he plastic is there at the moment because I am still figuring out how high I want to mulch upwards.
The water holding media I have used in these (street tree clipping/mulch) was generally no more than hand (finger tip to wrist) deep, for my hand 20cm. The AgPipe lays on the bottom (Builders plastic) and is covered by an inch or two of mulch, or more if I thought I wanted/needed more. Hence often the media would have only been 15cm, prior to a bit of compaction from the soil going on top.
Also I realise the plastic is not that strong and I may get a few leaks over time given the sharp nature of the mulch, but it was something again I could live with given my location and requirements. Hey I started with sand, I am not all that picky yet. Plus I realise that this is a “trial” and in 2-3 years I will be digging up the beds, redesigning, using pond liner, and maybe gravel/blue metal, however in the mean time I will get 3 years of vegies and when I flip the bed out I will have all that rotted organic matter to mix into the new bed.
So the drain, or drains is cut in at the media/soil interface, I drill a few large holes 40mm place an icecream container over the outlet and then put the mulch back around it. Bear in mind I have sand so this will drain well enough, if you dont I wouldn’t be so sure. If you are in a high rainfall poor drainage area I suggest you use the shadecloth sided beds. You then could semi sink your water holding media into the soil and have the ground level at the same hight as the interface. This should allow biological transfer between the earth and beds, but maybe not earthworms, hence why you need worm boxs, Bio Boxes in the Wicking Beds.
Hope that helps confuse you more 🙂May 30, 2010 at 9:18 pm #466934
Wow, nice job there, Charles!May 31, 2010 at 5:58 am #466935
Charles many thanks for the extra infoMay 31, 2010 at 9:45 am #466936
Hi Charles in picture nine it it some Atlantis water cells I can see in the background..ColMay 31, 2010 at 1:18 pm #466937
Looking good Charles… are you in North Perth or thereabouts?
When I get a spare few seconds or so, I’ll send you through a list of the heirloom seeds I have… We’re in Freo and only growing heirloom veg… so could add to the list you were talking about in another thread.
Your garden looks amazingly productive.
I love how you’ve used the Perth ‘sand’ to your advantage… interesting slant on the original wicking beds, that looks perfectly adapted to our WA environment.
Good on you :tup:June 1, 2010 at 12:55 am #466938
Hey Charles the garden looks great and I don’t ven have to drive down the road to see it. I think I will be drawing on your knowledge and expertise once we move to Busselton. BernJune 1, 2010 at 1:57 am #466939
Col – Not sure what you mean, if its wicking bed 9 picture, in the background there is just seed trays, flats and individual, agpipe roll, pots and other junk.
Erthgrl – I am in Innaloo, which is near Karrinyup/Doubleview/Osbourne Park if any of that is familiar, Yes thanks would love your involvement I might try and get in touch with the Freo Gardeners group and organise a talk/meet and greet in the next month or so, you folks are well ahead of the rest of Perth and I would like to take that initiative and extend it.
Bern – Happy to help when you get down there, can I suggest you get some piles of mulch top soil and manure and push them up into big mounds ASAP then we will have some nice soil to use as apposed to buying stuff. It needs to stay moist if possible.June 1, 2010 at 3:43 am #466940
Okay seed trays.. just looked like Atlantis cells. ( plumbers have them) . by the way I’m thinking of getting some so the run-off from the WB can be recycled
