I came across the Keyhole gardening concept while browsing through the web for an efficient method of gardening that is self-sufficient and a minimalist gardener’s delight. Many parts of the world are ill equipped with regards to rain and sun-shine; they are not blessed as the fertile regions of the world. A minimalist system of Keyhole Gardening for herbs that feeds itself with natural compost is certainly the need of the hour.
I was amazed with the idea and my thoughts are that this concept would be very successful for herb garden that yields the year round. You can plant companion herb plants or edible flowering plants like marigold and dandelions and the herb garden would turn out terrific indeed.
