Our aim is to make a productive fruit and vegetable garden with zero external inputs or outputs. That means that everything comes from within the garden including fertiliser. Being organic gardeners, we do not use chemical fertiliser mainly because of huge amounts of energy used to make it and the mining of mineral like phosphates is not sustainable. So, we make our own from Comfrey, or Symphytum, and nettles both of which are grown in the garden.
The Comfrey patch. When buying Comfrey plants make sure you use the Bocking 14 variety as it will not spread! We have used Dalmore Croft for many years – no connection just happy customers.
In the previous garden we made comfrey juice by filling barrels with the leaves and stems and then pressing the contents with broken paving slabs. It worked very well, there are details here. In the new garden we will do exactly the same but in 60Ltr, barrels.
There is also a simple way of extracting the juice using a piece of pipe and a bottle weight. Details here
Lawrence Hills, the founder of HDRA analysed comfrey juice and found that the nutrient content was very similar to Tomorite. We are also making nettle liquid which is high in phosphorous. Combined with comfrey juice this will make a balanced fertiliser.
Please note: we make concentrated juices and NOT comfrey teas. The juice is pressed out of the plant without adding water.
This is how we added the drain and made a stand for the barrels.
