Trials in the United States have shown that laying sheets of tin foil over the ground under chili plants (I kid you not) can dramatically reduce pest damage & up yields by a whooping 75%.
This works by reflecting more light up onto the plants, which boosts their growth. The effect of being lit from both above and below may also confuse insect pests who instinctively hide on the shady underside of leaves, causing them to seek out food elsewhere.

Based on an exhaustive review of the most cutting edge scientific research, my new RHS book reveals for the first time the secrets to growing crops for measurablyimproved flavour and nutrition.
Translating geek speak into a set of simple tips & tricks, it shows how anyone can grow maximum flavour with minimum labour.
A true spice fiend? Well I have a trick for you too! Growing chilies in a greenhouse can dramatically stoke their fieriness.
This is because chilies produce more capsaicin (the chemical responsible for their burn) in warmer conditions. Literally the hotter the spot, the hotter your crop.
Pop your little plants on the top shelf for maximum warmth & line the shelves with tin foil for a real double whammy.
