Catnip can be grown from seed, or purchased as a small plant from the garden centre, however it is very easy to propagate by dividing existing plants, so ask your allotment neighbours and if they are growing any you will probably find they are only too happy to give you some for free.
Catnip is usually upright growing and usually reaches a height of between 30-60cm, and plants should be set between 25-30cm apart. Mix in plenty of well rotted manure before planting, and if planting in pots as recommended it's also worth using some water retaining gel in the compost mixture.
