I decided to make use ofthe old sink that had outgrown it's first use as a herb garden. I keep herbs by the back door, and the plants in the sink were always neglected.I decided to turn it into an alpine garden, which was surprisingly easy to do.I had already built up a collection of old stones and pebbles; and the garden had some gravel.I bought 2 plants from a garden center at £2.50 each and two more from a car boot sale at £1.50 each! So the whole thing cost less than £10 to make, since I used my own compost! Very good value don't you think?
