Using the Great No-Dig concept but adding the age old technique of constructing a HotBed we can create a growing space that will allow us to harness the free heat generated by composting manure to grow early crops.
I have used this method for years and although its simple it gives great results
This technique was used at Chatsworth and Heligan to grow pineapples and Citrus in purpose made beds I have just taken this technique and adapted it for Vegetables using readily available Horse Manure
If you would more information on Hotbeds I have compiled a resource post which contains all my films on hotbeds, just click the link below
If you want the best Vegetables the effort of constructing a deep bed for vegetable growing is well worth the effort. This applies to some of the deep rooted vegetables that are going to stay in the bed longer than one season or to overcome a problem with your natural soil being either to heavy or nutrient/food starved.First made popular by Geoff Hamilton I have been growing in these for over 30 years, they work and improve with time
One variation I use a lot is a No dig version of a raised bed this link shows you how to build a No dig bed in under 30 minutes
