Planting Dahlias
Create excellent soil for dahlia tubers. They feed reasonably heavily and if you want strong plants, it pays to double dig the soil and
add significant amounts of compost.
Dahlia grow and flower much better in a well-drained organic soil than they do in sand or clay. Clay, quite frankly isnt a good soil for
this plant as it can rot it in heavy rains.
Planting
Aim to have the tuber (no matter how large) with a maximum of 2-inches of soil over top of it. (you can squeeze by with a touch more but not too much) Deeper plantings will reduce the flowering.
Smaller or dwarf varieties can be planted so that only 1 inch of soil is over top of the tuber.
Plant the tubers so they are roughly 12-18 inches apart for larger/taller varieties and 8-12 inches apart for shorter, dwarf varieties.
This plant wants a full sun location. The more sunshine, the better it flowers. It needs sunshine by 10 am to produce a full crop of flowers.
