Healthy bulbs give you gorgeous displays, so choose carefully to get the most bang for your buck!

When it comes to bulbs (like so much in life), you really reap what you sow. If you pick subpar bulbs, you’ll get a subpar display. But if you choose carefully and pick only healthy bulbs, watch out – the flower power will amaze you!

Let’s face it: Bulbs aren’t the prettiest to start out with – so how can you tell which are the “best” for your garden? Believe it or not, there are some key features to clue you into which bulbs are better than others:

Size. Yes, when it comes to bulbs, bigger is better. That’s because larger bulbs simply have more volume to store nutrients and moisture. They’re also able to weather storage and handling better than smaller ones. And here’s a bonus: Sometimes big bulbs produce multiple blooms!

Cuts, gouges and bruises (like on the bulb on the left) can lead to decay after planting. Stick with the undamaged bulbs for the best planting results.

Firmness. Solid bulbs that feel heavy for their size perform best. These bulbs are generally free of fungal disease and excessive drying. (Of course, some tuberous roots and rhizomes naturally appear dry and withered, so don’t hold that against them.)

Dormancy.Bulbs that are dormant won’t have any sprouts, so it’s early growth will focus on establishing strong roots – and that’s good. If your bulbs have green sprouts, plant them immediately.

Bulbs that have superficial splits in their onionskin-like coverings (like this one) are acceptable to buy and plant.

Freshness. Buy bulbs when they first appear in your garden retailer, storing them under ideal conditions if necessary until planting time arrives. (That means keeping them in breathable bags – don’t shut them up in zip-tight ones.)

Avoid any bulbs with signs of decay or mildew (like the bulb on the left), as well as ones that look shriveled and dry. Instead, opt for robust bulbs that look and feel heavy for their size.
Garden centers and nurs-
eries usually stock spring-bloom-
ing bulbs in fall, and they sell summer-, autumn- and winter-blooming bulbs in spring, allowing you to plant when the time is right for your area. If you miss them at your garden center, take advantage of direct merchants, including specialty bulb retailers that have unusual hybrids and cultivars rarely available in local, general-gardening outlets. Pass by pre-bagged assorted varieties, and choose the best individual bulbs available.

Once you get your bulbs home, all that’s left is to plant them right, water them in and wait for the show to begin!

Facts
  • If you’ve ever bought tulips, you’ve probably noticed that they’ve got all kinds of names. That’s because they’re grouped by species or hybrid cultivars, then classified into one of 15 major divisions.
Tips
  • Extend your bloom by doubling the number of bulbs, staggering them vertically in the soil and alternating early- and late-blooming varieties of the same species. In containers, plant the late-blooming variety beneath the early bloomer for the best displays.

  • Wherever you buy your bulbs, deal only with quality merchants whose staff is experienced in local growing conditions and your plant hardiness zone. Avoid closeouts and out-of-season displays at retailers with limited garden knowledge.
Resources
  • Many garden centers display their bulbs in convenient bins so you can pick through them to select the healthiest ones. When buying your selection, it’s a good idea to jot down the species (including cultivar name), bloom color, bloom height, planting depth and how many of each type you picked. This information will help you immensely when it comes time to plant again next year. Want to learn more about a particular type of bulb? Look the plant name up in the Learn2Grow Plant Database.
