We have had soil wrong for a long time. Find out how to get it right! We know that soil is the fundamental building block for life on the planet, yet we have managed to lose two thirds of the glue, called humus, that holds our soil together and keeps it healthy. 

Soil health plays a major role in all manner of gardening challenges and successes and this session will enthuse you to actively grow soil. Soil humus levels should be at 5% of soil volume, but with an average level of a paltry 1.5%,  we need to lift our game. Why? Lifting the humus level by just 1% will increase the water holding capacity of 1sqM of soil 200mm deep by 17 litres. 

This session will explore how how increasing the humus levels not only helps water retention in the soil you grow your vegetables in, but can affect the amount and frequency of pests that invade your patch and the density of nutrients in the food that you produce.  It will also show you some simple ways you can test the health of your soil and provide you with some practical approaches you can incorporate to help your crops be pest free, nutrient dense and full of real flavour. 

This session is taken by Craig Castree, bio can be seen below.

Absolutely loved this! It was a real light built moment for me. I've been struggling with growing vegetables and nearly gave up altogether until watching this. I was doing everything wrong and my vegetables were weak sickly and decimated by pests. I feel armed and ready now to have another go as it just makes sense to me now. Thank you so much.
