WHY GROW DAHLIAS? They keep getting better and better in late summer and autumn when many plants are fading. They offer opulent flowers with lush colors and astonishing forms. And the more you cut them for bouquets, the more they bloom.
HISTORY — Dahlias were brought into gardens by the Aztecs, arrived in Europe in 1789, and by the 1840s garden writers in America were hailing scores of new varieties every year. Exciting new cactus forms were introduced in the 1870s, and in 1927 F. F. Rockwell reported that dahlias ranked in “the leading position of all bulbs grown in America.”

DAHLIAS AS CUT FLOWERS — For tips for longer lasting dahlias in bouquets, see our Bulbs as Cut Flowers page.
TIPS FOR SUCCESS — Dahlias prefer full sun and rich soil. Blazing hot summers are hard on them, but see our tips for the Deep South, below. Yes, you’ll need to stake them, but it’s easy. No, you don’t HAVE to dig and store them — it’s not a law in any state! When they freeze dead, just add them to the compost pile. We send complete instructions with all of our bulbs.
PLANTING & CARE — DON’T plant outside too early! Wait till after all danger of frost is past — when you’d plant tomatoes or later. Or you can start them inside 4-6 weeks early and transplant them outside when it warms up, which is what we do here at Old House Gardens.
Dahlias thrive in light, fertile, well-drained soil. If your soil is heavy (clay), add organic material or plant in raised beds. Full sun is best, but eight hours will do. Dahlias do NOT like extreme heat, so avoid hot spots such as near south or west walls.
