Most of you know California is going through a pretty serious drought. We've only had a few days of rain since November (it's storming right now but I doubt a few days of rain are going to fill the very empty lakes and reservoirs in the Sierras). Many farmers are not going to be getting enough water for their fields...which means less fields will be planted...which turns into higher costs for the veggies that come from this area because there will be less available. We've been encouraged for quite some time to be careful with our usage...there are lots of dead lawns and the school I'm at has stopped watering the huge grass area for sports ( its completely brown).
I want to expand my garden but know how much water it takes to keep it going here. In normal weather times it stops raining around May/June and doesn't start back up until Sept/Oct. The weathers been so off lately who knows what will happen.
Our soil is very hard clay here so I've never bothered to try and dig...I garden on top. Raised beds and containers. The problem with containers is during the hottest months you sometimes have to water twice a day to keep things alive. Raised beds are good...but require the initial startup of buying the wood, etc.
I've been doing some research on hugulkultur which I heard about on the survival summit. It seems to be a simple, no or low cost way to build a bed and reduce water usage. I've started a small one in my backyard. It'll be interesting to see how this works. (I didn't dig a trench as it says in the directions. I just started a big pile)
What is Hugulkultur?
Hugulkultur is a German word translated as Hill Culture.
Turns out hugulkultur is a permacultural way of making raised beds using rotting wood, twigs, branches, hedge clippings, brassica stems, felled or discarded trees or any kind of wood that would otherwise have been burned or shredded.
How to make a Hugulkultur raised bed
The concept is brilliant yet so simple. You dig a trench about 30 centimetres deep and 1.5 metres wide. In the centre you dig another hole about 30 centimetres deep. You pile in all the woody bits and cover it with turf turned face down and then place well rotted compost, leaves, manure and the like over it.
The wood provides water retention, so less watering. Depending on how large the wood is that you are using the decaying process can take a few years. The raised beds are full of organic matter, nutrients and air pockets for roots to establish. As the composting process is still active it can be that the raised bed stays warm for a long time which will even extends the growing season. These raised beds are perfect for hungry crops such as courgettes and pumpkins.
It is a great way to use clippings, branches and twigs which would have taken a long time to compost or ended up in a shredder. This way uses up less energy and creates a perfect environment for your veg and for the creatures that live in the soil.
