Achieve Non-Stop Blooms with Fall-Planted Bulbs
Flowering bulbs come in a wide variety of species, colors, and plant habits. Compared to other plantings, bulbs are low-maintenance, requiring just one or two initial waterings around planting time. The reward for this small effort is nearly carefree flowers that return year after year, with some species more likely to naturalize than others.
Depending on the species and variety, fall-planted bulbs bloom from late winter to early summer. This means, as growers, we can incorporate bloom time into our landscaping plan to achieve impressive results! For the best bulb pairings, note the bloom time listed for each variety: this will make it easier to sync or stagger blooms depending on your needs. Find an outline of bloom times below with planting instructions at the bottom of this post.

BULB PLANTING BASICS
The ideal planting time is when nighttime temperatures are around 40-50°F, or about six weeks before the ground freezes. For us here in the Northeast, plant in October for maximum success. Early to mid-November is also okay. Most spring bulbs need a chilly period to bloom, so don't worry too much about getting them in the ground early or before your first frosts; however, after the ground has frozen, it can be difficult to get the bulbs established well enough to stay rooted during freeze-thaw cycles during winter.
Always plant bulbs into well-draining soil. Heavy clay soils often lead to rot. Pay close attention to spacing and depth requirements, but don't worry too much about fertility: average garden soil can lead to great flowers. If you're spacing very tightly and harvesting for flowers year after year, you'll want to apply a bit of compost and/or mulch, but other than that, amendments are rarely required unless you plant in exhausted soil. And if you do choose to fertilize, you can wait until the spring, since the dormant bulbs won't need it over the winter.
