This week’s guest is Nigel Palmer, an experimental gardener who brings to bear his experience as an aerospace engineer to analyse, identify and organise the various components that make plants grow well. From his research, he’s compiled a recipe book of garden amendments, some easy to make and some involving more complex methods, but all of which you can recreate at home and use on your garden for better plant health and resilience.

Why is local biological material important for a garden?

The theory behind feeding a plant with its own 'ancestors'

The ability of a plant to change the soil pH in the immediate vicinity of its roots

How plants need different nutrients and minerals at different stages of their development
