Why will we plant spring-flowering bulbs within the fall? These spring beauties are what we name “dormant perennials.” They want the cool, moist autumn soil to awaken them from their dormancy in order that they’ll start rising roots in preparation for the spring present.
They’re foolproof to plant—and feed early pollinators akin to these drowsy queen bumblebees.
One other factor to learn about fall bulbs is that they’re not all true “bulbs.” Irises, for instance, develop from rhizomes, whereas crocuses sprout from corms. Daffodils and tulips, then again, are true bulbs. Nonetheless, all of those crops are generally often called “fall bulbs,” so we seek advice from them as such on this article!

Within the warmest elements of the South, it’s possible you’ll must precool some bulbs. Most fall bulbs require a 12- to 16-week chilly interval, so place them in ventilated packages on the backside of your fridge at 40° to 50°F earlier than planting. Examine together with your bulb provider to find out whether or not the bulbs that you just bought have been precooled, or if you’ll need to offer them a chilly remedy.
Additionally, in hotter climates, be aware that some bulbs will bloom solely as soon as earlier than they’re completed. For instance, you’ll have to plant tulip bulbs annually. Nonetheless, they’re a gorgeous sight to behold and properly definitely worth the effort! Different fall bulbs, akin to daffodils, will act as perennials and are available up yr after yr.

We desire daffodils over some other bulbs as a result of squirrels, deer, and chipmunks go away them alone! Daffodils are available many colours—not simply yellow (pink, orange, white, multicolor)—and their flowers vary from trumpets to flat rings to little roselike cups. They develop greatest in well-draining soil that has been amended with natural matter or compost. They need to be planted a minimum of 6 inches deep and 6 inches aside.

7. Alliums (Decorative Onions)
*Deer-resistant!
In search of deer- and rodent-resistant bulbs? Attempt rising alliums—sure, members of the onion household!
These purple pom-pom flowers make a dramatic assertion in late spring and early summer time, particularly when planted en masse.
