Spring flowers are one of the most magical sights to behold after a long and cold Utah winter, but did you know the magic of spring blooms actually begins in the fall? Planting spring-flowering bulbs right now sets the stage for a spectacular early-season show. In this comprehensive guide, we'll dig into the art of planting tulips, crocus, daffodils, iris, and more!
Why Should I Plant Spring-Flowering Bulbs in the Fall?
As you probably know, spring-flowering bulbs require a chilling period of a minimum of 13 weeks. This makes Utah’s cold winter climate the perfect place to grow these beauties. Planting these bulbs in the fall gives them loads of time to establish strong root systems before the chili winter sets in, helping them gather enough nutrients and moisture from the soil to ensure a robust and healthy start in the spring. Cool temperatures allow robust root growth to sustain the bulb. The cold winter weather also triggers the bulbs' dormancy, assisting them to store energy for their stunning spring debut!
Choosing the Right Bulbs for Salt Lake City
Before you start planting, it's important to choose the right bulbs for your Salt Lake City garden. Here are some popular choices that thrive in our region:
1. Tulips
Tulips are one of the most iconic spring-flowering bulbs and are available in various colors and shapes that add vibrancy to any garden. For Salt Lake City, consider planting three seasons of blooms, early (Fosteriana), mid (Darwin Hybrid & Triumph), and late (long stemmed, Lily, Fringed, Parrot, Bunch Flowering) for extended spring blooms. Bunching Flowering are LaRene’s favorite!
2. Crocuses
Crocuses are among the earliest bloomers in spring, often poking right up through the snow. These cheerful, low-growing flowers come in shades of purple, white, and yellow and are perfect for naturalizing your garden.
3. Daffodils (Narcissus)
Daffodils are hardy and reliable spring flowering plants, making them an excellent choice for Utah gardens. Their bright yellow or white petals and trumpet-shaped centers always create a stunning display! Consider planting the unique multi stem or split corona varieties. Daffodils are also the very best for naturalizing because of their strong reblooms for years to come.
4. Irises
Irises come in a great selection of colors and sizes, making them an easy flower to fit into any garden design. They are also well-suited to Salt Lake City's climate and can be planted alongside other spring-flowering bulbs for a dynamic garden bed.
5. Alliums
The unique globe-shaped blooms of alliums, or ornamental onions, add a unique flourish to your garden. These bulbs are known for their deer resistance and make for show-stopping focal points in any garden design. They come in extra-large to small, from pink blooms to purple shades and white.
Preparing Your Garden for Planting
Now that you've chosen your bulbs, it's time to prepare your garden for planting! Follow these steps to ensure a successful bulb-planting experience:
Location, Location, Location
We suggest choosing a sunny spot in your garden for your bulbs, as they need at least six hours of sunlight daily to thrive. You should also make sure the soil drains well to prevent waterlogging your bulbs, which can cause rot.
Soil Preparation
Give bulbs a good home. Feed your soils by adding compost generously to the soil. It's crucial to amend the soil to provide optimal conditions for your bulbs. Be sure to add some bulb food too!
Digging to the Right Depth
The depth at which you plant your bulbs depends on their size. As a general rule, you should plant your bulbs at a depth that is around three times their bulb height. For example, if a bulb is 2 inches tall, planting depth should be around 6 inches deep.
Proper Spacing
Space your bulbs according to the recommended distance on the bulb packaging. Proper spacing allows for better air circulation and prevents overcrowding.
Planting Technique
For best results, plant your bulb in the hole with the pointed end facing up. Cover the bulb with soil and gently pat it down to remove air pockets. Finally, water thoroughly after planting to help settle the soil.
Bonus Tip: Plant Some Pansies
One of our favorite design tips is to plant pansies over your bulbs! Pansies are hardy, cool-season annuals that can actually survive our winters, providing an extra burst of early-season color come spring and brightening up your landscape during the colder months.

Caring for Your Spring-Flowering Bulbs
Just because your bulbs are in the ground doesn't mean your work is over! To ensure a stunning spring display, follow these care tips:
1. Mulch: Apply a layer of mulch over your planted bulbs to help regulate soil temperature, retain moisture, and prevent weed growth.
2. Watering: When watering your bulbs, keep the soil evenly moist but not waterlogged, especially during dry spells in the fall. Avoid overwatering, as bulbs can rot in soggy conditions.
3. Fertilization: Spread a balanced, slow-release fertilizer amongst your bulbs in the spring as the shoots emerge to provide them with the nutrients they need for flowering.
4. Deadheading: Once your spring-flowering bulbs have finished blooming, remove any spent flowers to encourage them to store their energy for the next year.
