Salt Sundays: a monthly reminder to fertilise with magnesium

Magnesium is an essential nutrient for photosynthesis and also for our human bodies functions. So it's important to make sure our vegetables are getting enough to feed them and then us. I talk about why it's essential for humans and plants, how to recognise a deficiency and how to prevent or correct the problem. Lastly, I introduce you to Salt Sundays so you never have a magnesium deficiency again.
