Now it is time for planting - a local nursery should have all the herbs you need.
Alternatively, you may wish to grow your own seedlings from seed or cuttings.
A good hint - water your herbs now, before they go on the spiral - they will be easier to remove from their containers and to plant.
Next step is the fun part - arrange you herbs on the spiral, whilst they are still in their pots, until you find balanced positions for them all.
If you have Dill and Fennel on the same spiral, place them on opposite sides as this will avoid cross-pollination..
