How To Plant Grow Dahlias, Part 5 Planting Dahlia Tubers

Dahlia tubers should not be planted in the garden until frost damage is unlikely. Dahlia tubers should be planted horizontally in holes 10 to 15 cm (4 - 6 inches) deep with the "eye" or young shoot pointed upward. The new growth is very easy to snap off so extra care must be exercised when planting tubers that have started to sprout. Do not be overly concerned if you break off a young shoot as there are generally other eyes that will provide alternate sites of growth. Cover the tuber and compress the soil lightly so as to make good contact with the tuber. It is not necessary to water in newly planted tubers unless the soil is very dry. Fertilizer in the planting hole is not recommended as new dahlia growth is very tender and may be damaged. Additional fertilizer may be applied as a side dressing later in the growing season. Dahlias are surface feeders so fertilizer applied as a side dressing will be quickly absorbed when watered in..
