In keeping with the organic gardening concept, it is always preferable to seek natural solutions to garden problems such as pests and common diseases.. Should you have any ideas to share on this topic please send them to us for passing on to others.

Please also note that dish-washing liquid is called for in most of these ‘recipes’. It serves as a ‘wetter’ enabling the liquid solution to adhere to the plant for maximum effect. The environmentally friendly non-toxic dish-washing liquid is ideal for this purpose. snail
