Can you grow better vegetables by experimenting with different compost mixes in your greenhouse?
In short: Charles Dowding tests how various compost blends affect plant growth. By comparing spinach and spring onions across thirteen pots, he reveals how different organic materials influence development over a six-week period.
In a controlled greenhouse experiment conducted from 4th April to 14th May, thirteen pots were used to evaluate plant performance in diverse growing media. The trial featured Medania spinach and White Lisbon spring onions, which were transplanted into the pots at four to six weeks of age.
The test compared four distinct compost types alongside Homeacres soil amended with varying quantities of vermicast. The materials included homemade compost aged eight to nine months, three-year-old woodchip, and Moorland Gold potting compost, all sieved to a four-millimeter consistency to ensure uniformity.
