Growing vegetables in small spaces or under adverse conditions can be a bit of a challenge at times This is where niche gardening ideas like the Keyhole Garden come into play, and small spaces can be converted to produce great results. Growing vegetables for some can be a rewarding pastime, whilst for others it is a question of survival - if you can't grow it, then you can't eat it Here we have one of the most successful of the Niche Vegetable Gardening ideas, but perhaps one that is the least talked about - Keyhole Gardening. Originally conceived off and promoted by the charity SendACow.org and now used successfully by many enthusiastic gardeners worldwide. Keyhole Gardening can now take its place amongst the other niche gardening methods such as Raised Bed, Square Foot, Straw Bale, and container gardening - to name but a few. If you would like to get the best results out of your vegetable growing efforts in small spaces or with limited resources - perhaps it's time to give the Keyhole Gardening concept a chance to impress
