I thought I should share my good success with a DIY wicking bed design.
I bought spotted gum (durable), galvanised fencing/ retaining wall stakes, extra thick builder's plastic, compost, sulfur to correct the very alkaline compost (boo), builder's sand, PVC pipes, joiners and caps, some wooden battens, things to screw/ staple/ nail it all together.
The recipe is as follows:
Only partially filled here - keep filling to ground level, where the spillway is.
Here we're testing to make sure it's water proof enough - the water has to sit in the reservoir so it can be sucked up by the compost heavy growing medium. You need a lot of compost to make sure the water will wick up to the top. It's basically just a giant self-watering pot.
This is the spill way side.
To use, put the garden hose in about once a week in summer and fill until you see water coming out the spillway. Also give the top a light sprinkle once or twice a week if you have seedlings (roots aren't long enough to get to the damp deeper soil yet) or in mid summer heat - or every day or two if you're sprouting seeds. No other watering required. Fill and leave on holidays - brilliant.
They look fantastic. Very productive too. What a lovely cottage as well. This is the first reasonable rain we've had in a long time.
Site is playing up for me, can't open any pictures on Scarlett's wicking bed notes. Also no banner or normal heading on site. Anyone else with this problem.
Good on my end
By Thursday, I was also getting some problems. It should be fixed now.
