Dahlia Mercator - This stunning, very large cactus Dahlia looks a bit like a bunch of candy canes shooting out from the centre of the blooms. Thin red stripes appear on the long vanilla tubular petals.

- The best time to plant Dahlias here in NZ is September or October, but can be planted anytime from mid August through to late December.

- Dahlias love sun ,so choose a nice sunny spot in your garden. Ideally a spot that gets at least 4 hours of full sun a day.

- Dahlias will grow in almost any soil, but prefer well drained loamy soil conditions.

- Prepare the ground a few weeks before planting by digging over the soil thoroughly and adding a little well rotted compost and an application of general fertiliser.

- Before planting the tubers, apply stakes (for larger varieties) staking after planting damages roots and tubers.

- Plant your Dahlia tubers about 5-10cm deep and about 50cm apart with the eye facing upwards. Water well and keep moist being careful not to over-water.
