Welcome to the blog of Johnathan Grieve. I am the proprietor of Avondale wine estate, and pioneer of the BioLOGIC® approach to sustainable viticulture. The transformation of Avondale from over-used and abused land into a thriving, robust vineyard ecosystem has been a personal learning journey of more than a decade long. This blog is where I share some of what I have learnt about promoting life on our farm and the wonderful impact this has had on our handcrafted premium quality wines.

What, and Why Biodynamic Preparation BD500?

What, and Why Biodynamic Preparation BD500?

Posted: November 19, 2014

In our first article of this series on Biodynamic preparations, I briefly introduced BD500, the powerful soil activator which is used to bring the above ground energies to the soil at the onset of Autumn. BD500 specifically stimulates calcium and nitrogen relationships to foster abundant, balanced life in the soil.

But what exactly is BD500?

Avondale’s innovative promotion of the Biodynamic Planting Calendar through our Luna Taste Test and our Biodynamic Luncheons have shown me just how many people are interested in how Biodynamic farming works. I’ve decided to start a new series of blog articles which will provide an overview of the Biodynamic preparations to explain what they are and why we use them.

Part 3 – What Kinds of Cover Crops?

In this series of articles about cover crops we’ve, so far, taken a closer look at cereals and legumes. The third major plant group commonly used as beneficial cover crops are the brassicas. The family Brassicaceae includes flowering plants that are generally known as the mustards and the crucifers.

How to create stable humus – protecting microbes

How to create stable humus – protecting microbes

Posted: August 22, 2014

In this series of articles on humus we’ve highlighted the four main reasons why humus is depleted in our soils, including conventional farming’s failure to protect the microbes that live in the soil. For too long there has been complete disregard for the fact that soil is a living system. There is such an extraordinary diversity of life in healthy soil that includes multitudes of species we have not yet named. In addition, even the world’s top soil scientists understand precious little about intricate workings and interactions in this fascinating ecosystem.

Extraordinary Food Experience – ‘Mariscos com Fredi’ on the Algarve

Posted: August 15, 2014

It was time to take a break from the wintry Avondale vineyards, and spend a sunny family holiday in the Algarve. We stayed at a friend’s holiday house in Quarteira, a settlement which has transformed over centuries from a small, simple fishing village into a major holiday destination, famous for its golden beaches and superb seafood.

Their great benefit is that they are a quality food source for the microbial life in your soil. Luxury levels of humic and fulvic acid are therefore integral to supporting the abundant, vigorous community of life in the soil that you need for healthy crop growth. Both humic and fulvic acids are available as agricultural products, and can be added to the soil or used as a foliar feed.

A legume is a plant in the family Fabaceae. Legumes are commonly farmed for their edible seeds which are consumed by people and farm animals, and also provide oils. The main legumes that we use as cover crops include bitter lupin, fava bean, vetch, clovers, medics, seredela and lucerne.

Weeds that can Work for You

Weeds that can Work for You

Posted: June 18, 2014

Some years back, I wrote a post on how Avondale regards weeds as useful storytellers, clueing us into what is happening with our soils. In the same vein, here are some interesting insights into the weeds known as Phytolacca, commonly called Inkweed or Pokeweed. Phytolacca are perennial plants native to North and South America, East Asia and New Zealand. Like any weed appearing on South African farming soils, it has a story to tell about its environmental conditions.

Part 1 – What Kinds of Cover Crops?

Posted: April 26, 2014

In this series of articles, I will get to discussing different species within those plant groups. However, the first 3 articles will deal with the plant groups. So let’s start here with cereals. A cereal is a grass from the monocot family Poaceae. They are commonly cultivated for the edibility of their grains, which are staple foods around the world. The main cereals that we use as cover crops include barley, oats, Saia oats, wheat and a cross between rye and wheat known as korrog or triticale.

As family man… Avondale is a family farm where we appreciate that the health and balance of our living system is inextricably linked to well-being of our families. As a father of two and a husband, as son and brother, my inspiration to achieve a robust, balanced vineyard ecosystem is to ensure that Avondale will support the lives of our future generations.

As artist… A passion for jazz and a love for all forms of art, especially woodwork and sculpture led me into four years of fine art studies – an eclectic education for a budding a farmer, for sure! However, I have found that in so many ways, the patterns, interconnections and openness of the artistic worldview have influenced my understanding of how living systems work.

As farmer… My interest in farming started early when I was a boy growing up on a small-holding outside of Durbanville. I planted and tended my own vegetables which I sold to family and friends. I hardly imagined at that time though that I would one day become a farmer. However, the theme of a healthy balanced life was embedded in our family’s outlook.
