We just put in a new wicking bed module.
I have always been rather impressed with how wicking beds work and have designed and made a
small prototype module, based on similar construction methods to similar beds.
The whole system works very efficiently so far, and I am keen to see how well it compares to my other raised vegetable beds.
I already have seen significant savings in water use so far as we have had only added about 10 litres over the last 5 to 6 weeks in it. We have had about 40 mm rain though and these are only new seedlings.
I am trying to keep accurate records and will do an informal trial to compare
the two systems. So far I am impressed with this module.
I planted capsicums, tomatoe, parsley, lettuce, and celery as the first crops in this bed .
Cropping dimensions are 1 square meter.
below our new bed is planted out and now 5 weeks old
cross section of our bed .
Step one: level the site
Step two: level the inner frame, reservoir into its position.
Step three: Slide the main raised garden frame over this section.
Step four: Place the filling tube into its position. Note the slits to the bottom.
Step five: Add the sand, and fill flat to the top of the resevoir.
Step six: Place the geotextile fabric over the sand, this stops the sand and the soil mixing.
Step seven: Add the soil to the top of the bed.
Step eight: Time to plant out!
I'm going to put a pdf document on my website with more comprehensive instructions.
