I've done a small herb garden on my plot using an 8' X 6' area. I acquired recycled bricks and marked out quadrants for my selected herbs. I've put a small eucalyptus in the middle and some mint in one quadrant. I acquired some roof slate from a neighbour who was having a new roof and buried it as a border around the plant, as mint is an invasive herb that is a prolific grower, so this stopped it from taking over the adjacent quadrants.

I've also put in a couple of different lavenders, parsley, oregano, basil, sage, chives and rosemary that were bought as small plants from my local garden centre for a reasonable price. All of these herbs have thrived in the herb garden and after 9 months had spread out, filling the area. The herbs are used in the kitchen at home and by friends.
