Why buy dahlia seeds and bulbs?
Dahlias are an easy plant to grow, require pretty minimal watering, and their variety of shapes, sizes, and colors means that there’s a suitable dahlia flower for almost any garden. Dahlias are a species of flower in the same family as sunflowers, daisies, chrysanthemums, and zinnias. They’re perennial flowers in warmer climates, meaning they’ll bloom again in the following years without needing to be replanted and do well when planted in flower beds mixed with other perennials.
What should you look for in dahlia seeds and bulbs?
- Quantity: Do you only want a single bloom, several, or a whole mess of them? Most bulbs are sold in packs of three to five at a time. You can, however, buy them only one at a time. You may prefer to purchase single bulbs if you’re after a specific color or set of colors and don’t want to leave it to the chance of an assorted collection of bulbs; this allows you to guarantee that you’ll have one red dahlia, one purple dahlia, etc. Or maybe you’re growing your flowers in a planter or pot instead of a garden or don’t have room in your garden bed for several plants. Buying dahlia tubers in larger sets may be a bit trickier, especially compared to seeds. Since they are relatively large flowers, they’re not often sold in big bulk packs.
- Colors: Various shades of pink, purple, yellow, orange, red, and white are the most common. There are also multicolored and striped dahlia flowers available. Some bulbs will be sold all in the same color, so you know you’ll be receiving and growing, say, three magenta dahlia bulbs. Others are sold in assorted packs, so you won’t know exactly which colors you’re getting until they’re fully grown and blossomed.
- Size: Depending on the type of dahlias your bulbs will grow into, they can be quite large flowers. Dinnerplate dahlias, for instance, may be a whole foot or more in diameter once they’re in full bloom. Some dahlias also can grow to a total height of 3 to 4 feet when fully mature. Some bulbs will list the estimated height and size their flowers will grow into, so be sure to consider that when you’re deciding where to plant them. Also, check if there’s a listing for how far apart you should space the dahlia bulbs when you plant them to ensure that there’s no overlap.
What’s the best planting environment for dahlia seeds and bulbs?
Dahlias are best planted once colder weather is entirely gone and the soil has had some time to warm up with the risk of frost over, depending on the climate you live in. If you want to start growing them a little sooner, you should plant them in pots and then transfer them outdoors once it’s warm enough. Dahlia seeds and bulbs alike thrive best in sunny areas with well-draining soil mixed with compost and planted in a wide, deep hole.
