How to Plant Authentic Dutch Flower Bulbs

Planting Dutch flower bulbs in the fall will yield beautiful blooms as soon as the winter frost retreats—and then keep your garden lively throughout the year. From early-blooming crocuses to late-spring alliums, Dutch bulbs offer a sequence of colors across the seasons. 

In the video above, This Old House landscape contractor Roger Cook demonstrates the proper techniques for planting various types of Dutch bulbs to create a stunning display. We’ll outline these techniques and add some tips for planting bulbs of your own.

Choosing the Flower Right Bulbs

Selecting the appropriate bulbs makes for a successful spring garden. Consider the following factors when making your choices.

Bloom Time

To ensure a continuous display of flowers throughout spring, select bulbs with varying bloom times:

• Early spring: Crocus, snowdrops, and glory-of-the-snow
• Mid-spring: Daffodils, hyacinths, and early tulips
• Late spring: Late tulips, alliums, and Spanish bluebells

By planting a mix of these bulbs, you can enjoy a garden that evolves as the season progresses. 

Climate Considerations

Choose bulbs that are well-suited to your local climate. Some bulbs, like daffodils, are more adaptable to various regions, while others may require specific growing conditions. Look up your USDA Hardiness Zone to determine which bulbs will thrive in your area. For example, tulips may struggle in warmer climates, whereas daffodils and alliums are known for their heat resilience.

Wildlife Resistance

In areas with high deer populations, it’s wise to opt for deer-resistant bulbs. As Cook mentions in the video, tulips are often a favorite snack for deer. Instead, he focuses on varieties like daffodils, alliums, and hyacinths, which are less appealing to wildlife. Additionally, bulbs like fritillaria and snowdrops can deter deer and rodents due to their unpalatable taste.

Preparing for Planting Flower Bulbs

Before you start digging, take some time to plan and prepare your planting area. Proper preparation will ensure your bulbs have the best chance to thrive come spring.

Timing

Plant Dutch bulbs in the fall, typically 6–8 weeks before the ground freezes. This allows the bulbs to establish roots before winter dormancy. Planting too early may lead to premature growth, while planting too late may not give the bulbs enough time to root properly.

Site Selection

Choose a location with well-draining soil and adequate sunlight. Most spring-flowering bulbs prefer full sun to partial shade. Avoid low-lying areas where water tends to collect, as the bulbs may rot before they have a chance to bloom. If you’re planting in a garden bed, consider the positioning of other plants to ensure the sprouting bulbs receive sufficient light.

Soil Preparation

Improve your soil by adding organic matter such as compost. This enhances drainage and provides nutrients for the bulbs. If your soil is heavy clay, consider amending it with sand or grit to improve drainage. The addition of a balanced fertilizer can also give bulbs a strong start.

Planting Techniques for Flower Bulbs

Cook demonstrates two main planting techniques in the video: individual planting for small areas and mass planting for larger spaces. 

Individual Planting

This technique is ideal for integrating bulbs into established garden beds or creating specific patterns. Use this method for delicate bulbs that need precise placement to thrive.

1. Lay out the bulbs on the surface of the soil to visualize the arrangement.
2. Use a hand trowel to dig holes that are 2.5 to 3 times the height of the bulb.
3. Add superphosphate fertilizer to the hole for long-term nourishment.
4. Place the bulb in the hole with the pointed end facing up.
5. Hand-mix a small amount of starter fertilizer into the removed soil.
6. Backfill with the fertilized soil and water thoroughly.

Mass Planting

Mass planting is efficient for creating large swathes of color. This method works well in open spaces or along pathways where you want a bold, uniform display.

1. Remove existing mulch using a steel rake.
2. Dig out a large area to the appropriate depth for the bulbs you’re planting.
3. Add superphosphate fertilizer to the bottom of the excavated area.
4. Place bulbs in the hole, spacing them appropriately.
5. Cover with soil, leaving the tips of the bulbs just barely exposed.
6. Water well and replace the mulch.

Layering Flower Bulbs

Cook demonstrates a technique called “layering” or “lasagna planting” in the video. This method allows you to maximize space and create a longer-lasting display. By layering bulbs based on their bloom time and size, you can achieve a continuous floral show from early spring to late summer.

1. Dig a hole deeper than you would for a single layer of bulbs.
2. Plant larger, later-blooming bulbs like daffodils at the bottom.
3. Add a layer of soil.
4. Plant medium-sized bulbs like hyacinths or tulips.
5. Add another layer of soil.
6. Finish with small, early-blooming bulbs like crocuses or snowdrops on top.

If you’d prefer to stick to one type of bulb, Cook recommends planting some bulbs on their sides. These will bloom later than those placed tip-up, extending the time you’ll have to enjoy your spring flowers.

Caring for Planted Flower Bulbs

Proper care after planting gives flowers the best chance at healthy growth and abundant blooms. Following these guidelines will help your bulbs flourish.

• Water thoroughly after planting to settle the soil and provide moisture for root development.
• Apply a layer of mulch to protect the bulbs from temperature fluctuations.
• Avoid overwatering during winter dormancy to prevent bulb rot.
• After flowering, allow the foliage to die back naturally to replenish the bulb’s energy for next year’s bloom.
• Use a balanced liquid fertilizer in the spring as shoots begin to emerge.

Companion Planting in Your Bulb Garden

Companion planting can enhance the beauty of your bulb garden and improve soil health. Consider pairing Dutch flower bulbs with compatible perennials and annuals to create dynamic, visually appealing displays.

Perennials

Perennials like hostas, peonies, and daylilies provide a lush backdrop for your bulbs and fill in the gaps when the bulb foliage dies back. They also help suppress weeds and retain soil moisture, promoting healthier bulb growth.

Annuals

Annuals such as pansies, petunias, and marigolds add a burst of color and fill in spaces between bulbs. They are versatile and can be changed yearly to create a fresh look in your garden.

Ground Covers

Ground covers like creeping thyme, ajuga, and periwinkle provide a beautiful carpet around your bulbs. These low-growing plants help retain soil moisture and reduce erosion while adding texture to your garden design.

Common Issues and Solutions When Growing Dutch Bulbs

Even with proper planning and care, issues can arise when growing Dutch bulbs. Here are some common problems and their solutions.

Pest Problems

Bulbs can attract pests like voles, squirrels, and deer. To protect your bulbs, consider using physical barriers such as wire mesh or planting in pots. Adding gravel or rocks to the soil discourages rodents from digging. You can also soak bulbs in repellent solutions or plant pest-resistant bulbs like allium.

Disease Management

Bulb rot and fungal infections are common issues. Ensure proper soil drainage and avoid overwatering to prevent these diseases. If you notice any diseased bulbs, remove and dispose of them immediately to prevent the spread.

Poor Growth

Good growth begins with thoughtful planting. If bulbs are not blooming or growing well, it may be due to poor soil, inadequate light, or overcrowding. Ensure your bulbs are planted in well-draining soil with sufficient nutrients. Provide adequate sunlight and space bulbs properly to avoid competition for resources.

Our Conclusion

Planting Dutch flower bulbs is a simple gardening project that pays dividends in spring beauty. By following expert Roger Cook’s advice on selection, planting techniques, and aftercare, you can create a stunning display of colorful blooms that will brighten your garden year after year. With a little planning and effort in the fall, you’ll be rewarded with a spectacular spring show.
