Say that five times fast!
This is a combination of two ideas I've come across in the last couple years. The one idea was a hexagonal shaped veggie garden with dug out clover shaped beds. The idea behind digging out the beds is so that you remove all large rocks and stones from the soil and mix that soil with compost, then loosely replace that soil. This creates an easy substrate for roots to grow in and increases productivity. Once refilled you NEVER stand there again and the clover shaped design allows you to reach any part of the bed easily. This idea of digging out and never standing on the bed I read about in the New Self Sufficient Gardener by John Seymour. It was referred to in there as 'the deep bed method' but has some other names.The hexagonal clover design was shown to me by a gentleman who works for the South African prison service in South Africa. They have a social development program where they show NGO's and schools and places this idea. Big Up!
The design of each clover shaped bed is achieved by placing three plastic rings (1m in diameter made from 3 meter pieces of 20mm or so plastic piping.) next to each other in one pie slice of the hexagon. Where the circles join you also break that away making one bed. This is dug to a depth of about 40 - 60 cm. Then a capsule, for watering, with perforated sides is placed in the middle of each circle so there are 3 capsules per bed.The original design used 2 litre coke bottles but I've made mine out of 110 mm drainage pipe about 60 cm long that hold around 5 litres
They say using this method and mulching you only need to water once a week! I have yet to confirm that but if it's true you could run an entire system, like I'm about to describe, for a whole year on water you can easily catch from rainwater harvesting off your roof!
This is the basic layout of each group of beds.
The watering capsules are placed in each circle.
(The circle should be joined but I couldn't make that happen in word :o)
