On the 28th of May 2016, I attended a companion planting workshop, presented by Karen Parkin and Saskia Schelling. Saskia (email@example.com) is a teacher, yoga instructor, garden coach and takes garden tours. She has turned her own garden into a permaculture project over a period of five years. The underlying soil is pale grey sand, but the principles she applies have allowed heavy feeding plants like bananas and brassicas to grow. Karen Parkin I have written about previously, when she gave a talk on harvesting food plant seeds in adherence to permaculture principles. Karen (firstname.lastname@example.org) has spent 20 years growing vegetables, and recently took a sabbatical to study indigenous herbalism and other healing modalities.
Permaculture is a way of growing organic vegetables by respecting the model of nature. Companion planting is a vital element in this modeling, as you will see from the five articles I've written on the workshop. The workshop brought me some new concepts, from the permaculture lexicon, such as the guild, plant antagonism, the geoderm, the wild world web and more.
In permaculture, a guild is a group of plants which suit growing together. This can be because of the creation of microclimates by one plant for another, or because they like similar circumstances like high nutrients and steady water supply, or they complement each other in terms of space utilization, in which each has a different niche, taking up underground space, and above ground low, medium and high growth. Lastly they guild can be due to chemical suitability, or the beneficial nature of one of the plants in terms of nutrient supply, and also there is chronological sequence.
Saskia gave the examble of the small banana grove in her garden where she places all the organic waste. The bananas are tall, the sweet potatoes act as a ground cover, and the Vetiver grass, scented similarly to lemon grass, which has a medium height and surrounds the bed.
The three sisters: maize (tall), squash(ground cover), legumes (climbers) are a classic example from indigenous America. A typical combination is roots and leaves which grow well together because they don’t compete for the same nutrients.
In a permaculture garden pioneers are planted first, like legumes, comfrey, yarrow, all fast and early flowering. Pioneers are plants which in the wild first establish themselves on disturbed soil, or a new surface of soil. There is a danger in this, which I will describe under tainted colours, on the the home page. The long term plants will come next, though they can be planted at the same time, they will flourish later, their climax is very slow, and to flourish they need the microclimates and soil quality created by the pioneer generation. They could be seen to constitute a guild across time, or a form of companion planting.
A further consideration when companion planting in a permaculture garden is the balancing of the elements earth, fire, water and air. You would need to research on which plants embody which elements. Chillis obviously are fire, as an example.
I will discuss other concepts taught at the workshop such as plant antagonism, and the wild world web, (an in house nickname for the mycelial network) the geoderm, and soil regeneration, dealing with pests the organic way, and planning and planting out a permaculture garden under these in text links.

Hello Caroline, thank you for your very informative article about the subject of compost toilets. I always enjoy the topics you cover on Greenidiom.com.
