The Greener Guide to Fall Flower Bulbs: Plant Today - Bloom In Spring!

After a long winter, nothing says "spring is here" quite like the burst of color and fragrance from blooming spring bulbs. Imagine stepping outside into the crisp spring air to the delightful aroma of hyacinths or the cheerful yellows of daffodils. To make that dream a reality, fall is the best time to plant your spring bulbs, ensuring that your garden has a bounty of beautiful and fragrant flowers come spring.

Planting spring bulbs is easy if you follow these steps.

1. When to Plant

The best time to plant bulbs in the Midwest, particularly in Wisconsin, is in the fall—about 6-8 weeks before the ground freezes. This allows the bulbs enough time to establish roots before winter sets in but prevents them from sprouting prematurely. Generally, aim to plant between late September and early November. 

2. Where to Plant

Spring bulbs thrive in well-drained soil with plenty of sunlight. Here’s a quick guide to choosing the perfect spot for different types of spring bulbs:

• Daffodils: Daffodils are easy to grow and thrive in sunny or partially shaded areas. They are also deer-resistant!
• Tulips: These need full sun to perform their best. Group them together for a stunning impact. You’ll have     to protect them from deer and rabbits.
• Hyacinths: Hyacinths prefer sunny spots but can tolerate partial shade. Their strong fragrance makes them perfect for areas close to pathways or entrances.  As a bonus, they are resistant to most wildlife including deer!
• Bluebells: Plant these in areas with partial shade, such as under trees or along borders. Although some     varieties are tempting to wildlife, most varieties draw little attention from deer.
• Crocus: These small but mighty blooms often show up first in spring. They enjoy full to partial sun and can be scattered across lawns or flower beds. These are mainly deer resistant, but the bulbs are tempting for rabbits, squirrels and voles.

Remember to select areas with good drainage. Bulbs do not like "wet feet," so avoid spots where water pools after rain. If your soil is clay-heavy, consider amending it with compost to improve drainage.

3. How to Plant

Planting bulbs is easy. Paying attention to the details will ensure you have a truly stunning display come spring.

• Depth: A good rule of thumb is to plant bulbs 2-3 times as deep as their height. Larger bulbs like tulips and daffodils should be planted 6-8 inches deep, while smaller bulbs like crocus can be planted 3-4 inches deep.
• Spacing: For a more natural look, plant bulbs in clusters rather than straight rows. Daffodils and tulips should be spaced 4-6 inches apart, while smaller bulbs can be spaced 3 inches apart.
• Orientation: Don’t plant your bulbs upside down! Bulbs have a pointy side (where the sprout will emerge) and a flatter, wider base (where the roots grow). The pointy side should face upward.
• Watering: After planting, give your bulbs a good drink of water. This helps them settle in and encourages     root growth. However, don’t overwater, especially in areas with poor drainage.

4. Protecting Bulbs Over Winter

In Wisconsin, and Midwest climates, cold winters are common and spring bulbs like tulips, daffodils, crocus and hyacinths are built to handle the chill. You can help protect them by mulching your bulb planting areas with straw, leaves, or bark for a little added insulation. Mulching can also help retain moisture and prevent weeds.

5. Protecting Bulbs from Wildlife

While bulbs are easy to plant, they are also easy targets for a number of critters. Squirrels, chipmunks, skunks, voles, raccoons, and rabbits will dig out bulbs to eat. Follow these suggestions to keep your newly planted bulbs in the ground.

• Wire Mesh/Cages: Place wire mesh, such as chicken wire or bulb cages, over the planted area to prevent animals from digging up your bulbs. You can bury the mesh just below the soil surface to protect from voles and mice or place it over the bulbs, allowing plants to grow through it.
• Plant Resistant Bulbs: Some bulbs, like daffodils, alliums, and hyacinths, are less appealing to wildlife and may help reduce the risk of damage. Incorporating these bulbs into your garden can help protect more vulnerable plants.
• Install Physical Barriers: Use fencing or row covers to physically block access to areas where bulbs are planted. Make sure the barrier is buried a few inches into the soil to prevent animals from burrowing underneath.

In early Spring, watch out for deer. They especially love tulips. Be Green Pro offers a Deer Repellent Service that protects your young plants from grazing deer.

6. Bulbs in Containers

If you’re planting bulbs in pots for spring blooms, here’s what you need to know:

• Use large containers with good drainage.
• Plant bulbs just as you would in the ground—pointy side up and at the correct depth.
• For winter protection, pots should either be moved to an unheated garage or wrapped well to protect them from freezing solid.
• Water the bulbs lightly throughout the winter, just enough to keep the soil from drying out completely.

7. Choosing the Best Bulbs

To ensure you have a beautiful spring display, choose high-quality bulbs (this is truly a case of you get what your pay for). Look for firm, plump bulbs without any soft spots or mold. Larger bulbs tend to produce bigger blooms, so don’t be afraid to splurge a little. Shop early for the best selection.

8. Caring For Your Bulbs After Blooms Fade

Once your spring bulbs have finished blooming, it’s essential to let the foliage die back naturally. This process allows the bulb to absorb nutrients for the next season’s bloom. Don’t be tempted to cut the leaves off immediately—wait until they turn yellow and wither. For some bulbs, like tulips and hyacinths, this process can take a few weeks.

If you plan to dig up your bulbs to replant in the fall, wait until the foliage has fully died back. Store them in a cool, dry place until you’re ready to replant.

Planting spring bulbs in the fall is a simple and rewarding way to add beauty, color, and fragrance to your garden after a long Wisconsin winter. With the right preparation and care, your bulbs will provide a delightful display year after year. Get planting today and enjoy the benefits come spring!
