Introduction
There is nothing quite like the sight of the first daffodils peeking through the soil to signal that spring has finally arrived. Their cheerful yellow and white trumpets are a welcome reward after a long winter, and it is natural to want to get started on your own garden display as soon as the weather warms up. If you find yourself with a handful of bulbs or a sudden burst of gardening inspiration in July or August, you might wonder if you can put those bulbs in the ground right away. If you want to browse the full range, start with our trumpet daffodils. (longfield-gardens.com)
At Longfield Gardens, we want to help you achieve the best possible results with every bulb you plant. While the excitement of gardening often hits its peak during the sunny summer months, daffodils follow a specific biological clock that thrives on the rhythm of the seasons. Understanding this cycle is the secret to a stress-free garden that returns year after year with more blooms than the last.
This guide will explain why summer is generally a time for rest rather than planting for daffodil bulbs. We will also cover the exceptions to the rule, such as when you are moving established bulbs, and how you can use the summer months to prepare for a spectacular spring.

While you shouldn’t typically plant new daffodil bulbs in the heat of summer, this season is the perfect time to plan, prepare your soil, and secure your favorite varieties for autumn planting.
The Biological Clock of a Daffodil Bulb
To understand why summer planting is not the standard practice, it helps to look at what is happening inside the bulb. A daffodil bulb is a self-contained storage system. It holds all the energy and even the tiny embryonic flower needed for the following year.
In the spring, the bulb uses its stored energy to send up leaves and flowers. Once the blooms fade, the leaves spend several weeks soaking up sunlight. This process, called photosynthesis, recharges the bulb for the next season. By early summer, the leaves turn yellow and die back. At this point, the bulb enters a state of dormancy, which is essentially a deep sleep.
During this summer dormancy, the bulb is not growing roots or leaves. It is simply waiting for the soil temperatures to drop. If you plant a dormant bulb into hot summer soil, it stays in that "sleep" state. However, the conditions in a summer garden—warmth and often high moisture from irrigation—can be problematic for a dormant bulb.
Why Summer Isn't Ideal for New Planting
When you buy new daffodil bulbs, they are typically harvested in late summer and shipped in the fall. If you happen to have bulbs in your hand during the summer, planting them immediately presents a few challenges.
The Risk of Bulb Rot
Daffodils are incredibly hardy, but their primary enemy is excessive moisture combined with high heat. We often use the word "drainage" to describe how fast water leaves the soil. In the summer, many gardeners water their perennial beds or vegetable patches frequently.
If a dormant daffodil bulb sits in warm, wet soil without active roots to pull that moisture away, it becomes susceptible to fungal issues. One common issue is basal rot. This fungus thrives when soil temperatures are high. By waiting until the fall to plant, you ensure the soil is cool enough to keep these fungi inactive while the bulb begins to grow its new root system.
Soil Temperature and Root Growth
Daffodils need a period of cool soil to trigger root growth. In most parts of the United States, summer soil is far too warm to signal the bulb to start working. Roots are the foundation of a healthy flower. When you plant in the fall, the cooling earth tells the bulb it is time to wake up and establish itself before the ground freezes.
Lack of Availability
Most high-quality growers, including those we work with in Holland, do not even harvest their bulbs until the mid-summer months. This means that fresh, healthy bulbs are usually not available for purchase until the late summer or early autumn. Any bulbs you find for sale in the heat of June or July may be left over from the previous year, which means they might be dried out and less likely to thrive. If you want a broader shopping starting point, our assorted daffodils are a good place to compare styles. (longfield-gardens.com)
Key Takeaway: Summer is the resting phase for daffodils. For the healthiest plants, it is best to respect this period of dormancy and wait for the cooling temperatures of autumn to put new bulbs in the ground.
The One Exception: Moving and Dividing Existing Bulbs
While we don't recommend planting new bulbs in the summer, you might find yourself "planting" because you are moving bulbs that are already in your garden. This is a common summer task for many gardeners.
If your daffodil clumps have become crowded and are producing fewer flowers, it is time to divide them. This process usually happens in late spring or very early summer, just as the foliage is starting to turn yellow.
When to Lift Your Bulbs
The best time to dig up your daffodils is when the leaves have turned mostly yellow but haven't completely disappeared. This allows you to see exactly where the bulbs are located so you don't accidentally slice through them with your shovel.
How to Replant Immediately
If you are moving bulbs from one part of your yard to another, you can replant them immediately after digging them up. Even though it is summer, these bulbs are "fresh" and have been acclimated to your local soil.
- Dig the clump carefully, staying several inches away from the stems.
- Gently pull the bulbs apart by hand.
- Choose a new spot with excellent drainage.
- Replant them at the same depth they were previously (usually about 6 inches deep).
- Let the soil stay dry; do not overwater the area during the summer.
How to Use Summer to Prepare for Fall
Even though the shovels stay in the shed for a few more months, summer is a vital time for a successful daffodil garden. Use these months to set yourself up for a stress-free planting season in the fall.
Order Your Bulbs Early
The best way to ensure you get the specific colors and shapes you want is to order in the summer. At Longfield Gardens, we begin taking orders long before the planting season starts. Many unique or highly sought-after varieties sell out quickly. By choosing your favorites in July or August, you ensure they are reserved for you and will ship exactly when the weather is right for your specific region. You can also shop our Daffodil Bulk Buys & Collections for larger plantings. (longfield-gardens.com)
Evaluate Your Garden Spaces
Summer is the best time to look at your landscape and identify where you need more color. Since the rest of your perennials are in full bloom, you can easily spot "holes" in the garden where a burst of spring yellow would look perfect. Take photos of your garden now so you can remember where the empty spots are when the perennials die back in the fall.
Soil Preparation
You don't have to wait for the cool weather to start improving your soil. If you have an area with heavy clay, summer is a great time to work in some organic matter, like compost or aged bark.
- Check your drainage: If you notice water puddling in a certain spot after a summer rainstorm, that area is not a good fit for daffodils.
- Remove weeds: Keeping a planting bed clear of weeds during the summer makes the actual planting process much faster and easier in October.
What to do next:
- Walk your yard and take photos of areas that look "green but boring."
- Browse online catalogs to find varieties that match your garden’s color palette.
- Check the condition of your garden tools, specifically your trowel or bulb planter.
Storing Bulbs During the Summer
If you happen to acquire bulbs during the summer—perhaps a friend gave you some from their garden or you found a deal you couldn't pass up—you must store them correctly until fall. Proper storage keeps the bulbs firm and healthy.
Keep Them Cool and Dry
The worst place for a bulb in the summer is a plastic bag or a sealed container. Bulbs are living things and need to breathe.
- Use mesh bags: Store your bulbs in a mesh or "onion" bag, or even an old pair of pantyhose. This allows air to circulate around each bulb.
- Find a dark spot: A cool, dry basement, a well-ventilated garage, or a shaded potting shed are all good options.
- Avoid the fridge (mostly): While some southern gardeners "pre-chill" bulbs in the refrigerator, you should never store bulbs near ripening fruit like apples or pears. These fruits release ethylene gas, which can kill the tiny flower bud inside the bulb.
Monitor for Quality
Check your stored bulbs once a month. They should feel heavy and firm, like a fresh onion. If a bulb feels light, hollow, or "squishy," it has likely dried out or begun to rot and should be discarded. A little bit of surface mold is usually fine and can be brushed off, but the bulb itself must remain firm.
When Is the Right Time to Plant?
Since summer is off the table for new bulbs, when should you start digging? The answer depends on where you live. Most gardeners in the United States will plant their daffodil bulbs between late September and late November. For zone-based shipping and timing, review our shipping information.

The Temperature Rule
The most reliable guide is not a date on the calendar, but the temperature of your soil. You want to wait until the soil temperature is consistently 60°F or cooler. If the air is starting to feel crisp and you have had a few light frosts, it is usually a great time to plant.
Regional Timing
- Northern Climates (Zones 3-5): September and October are your prime planting months. You want the bulbs in the ground at least a few weeks before the soil freezes solid.
- Mid-Country (Zones 6-7): October and November provide the ideal window.
- Southern Climates (Zones 8-10): You may wait until December or even early January. In these warmer areas, the "summer" heat lingers much longer, so patience is key.
Choosing the Right Varieties in Summer
While you are waiting for the fall, take some time to learn about the different types of daffodils. Not all daffodils are just "yellow trumpets." By selecting a mix of varieties, you can have flowers blooming for six weeks or more. A helpful overview is our Types of Daffodils to Know and Grow. (longfield-gardens.com)
Early-Season Varieties
These are the first to wake up. They often bloom alongside crocuses. Look for "Rijnveld’s Early Sensation" or small botanical types that brave the late winter chills.
Mid-Season Varieties
This is the peak of the daffodil season. Large-cupped daffodils and the classic "Trumpet" styles dominate this window. These are the iconic flowers most people picture when they think of spring. If you want a closer look at the style group, browse our trumpet daffodils. (longfield-gardens.com)
Late-Season Varieties
As the weather starts to truly warm up in late spring, late-bloomers take the stage. Varieties like "Poeticus" daffodils or the fragrant "Pheasant’s Eye" are wonderful for extending the season into May. One classic option is Daffodil Poeticus Actaea. (longfield-gardens.com)
Consider Height and Fragrance
If you are planting near a walkway, look for fragrant varieties. If you are planting in a windy area, look for shorter "miniature" daffodils that won't get knocked over by a spring breeze. For a ready-made mix, try the Daffodil Assorted Fragrant Daffodil Collection. (longfield-gardens.com)
Simple Steps for Fall Success
When the heat of summer finally breaks and the leaves begin to turn, it is time to put your plan into action. Planting daffodils is one of the simplest gardening tasks, and getting the basics right ensures years of beauty. If you want a broader planning reference, see the Planning Guide for Daffodils. (longfield-gardens.com)
Depth and Spacing
The "rule of thumb" for most bulbs is to plant them three times as deep as the bulb is tall. For a standard daffodil, this usually means the base of the bulb is about 6 inches below the soil surface.
- Pointy end up: The bulb should sit in the hole with the pointed tip facing the sky.
- Spacing: Give them some elbow room. Planting them 4 to 6 inches apart allows them room to grow and multiply over the years.
Water Deeply, Then Wait
After you finish your fall planting, give the area a good soaking. This settles the soil around the bulb and "wakes up" the roots. After that initial watering, you can usually rely on autumn rains to take over. Unless you are experiencing an extreme drought, you won't need to water again until you see green shoots in the spring.
The "One and Done" Rule
Daffodils are incredibly self-sufficient. Once they are in the ground at the right depth and in the right spot, they don't need much from us. They are deer-resistant and rabbit-resistant, making them a very "safe" bet for most home gardens.
Key Takeaway: Success with daffodils comes from matching the plant to the right conditions. By choosing a sunny spot with good drainage and waiting for the cool fall air, you are giving your bulbs the best start possible.
Realistic Expectations for Your Garden
Gardening is a partnership with nature, and while we can provide the best bulbs and the best advice, the weather always has the final say. Some years, a warm spring might make the flowers bloom earlier and fade faster. Other years, a long, cool spring will keep the daffodils looking perfect for weeks.
It is also important to remember that daffodils are a long-term investment. The first year they bloom, they will look lovely. But as the years go by, the bulbs will naturally multiply underground, creating larger and more impressive clumps of color. This "naturalizing" is one of the greatest joys of growing daffodils.
If a bulb doesn't bloom the first year, it is usually due to the previous year's weather at the growing farm or a lack of moisture during its root-growing phase in the fall. However, daffodils are resilient. Even if they have a "shy" year, they often bounce back the following season with renewed vigor.
Using Bulbs in Containers
If you don't have a large yard or you want color on your porch, you can also plan for summer container projects. While the same rules apply—don't plant them in the summer for summer blooms—you can prepare your pots in the fall.
During the summer, you can shop for decorative pots or planters. Look for containers with large drainage holes. In the fall, you can plant your daffodil bulbs in these pots, bury the pots in the ground or store them in a cool garage for the winter, and bring them out in the spring for an instant display. You can also browse the wider Learn section for more seasonal how-to guides. (longfield-gardens.com)
Conclusion
While the urge to plant may be strong during the height of summer, your daffodil bulbs will be much happier if you allow them to finish their summer nap. By avoiding the heat and moisture of summer planting, you protect your bulbs from rot and ensure they have the cool soil they need to thrive.
Instead of digging in the heat, use the summer months to dream and plan. At Longfield Gardens, we believe that a little bit of planning in July leads to a much more beautiful garden in April. Focus on selecting high-quality varieties, preparing your soil, and clearing your planting beds. When the autumn breeze finally arrives, you will be ready to plant with confidence.
- Order early to get the best selection of varieties.
- Store bulbs in a cool, dry, airy place if you have them during the summer.

FAQ
Can I buy daffodil bulbs in the summer?
Yes, you can often pre-order daffodil bulbs during the summer months. Most reputable retailers, including our team, begin taking orders in the summer to ensure customers get their preferred varieties. However, the bulbs themselves are usually not shipped until the fall, which is the appropriate time for planting in your specific climate zone.
What happens if I plant a daffodil bulb in July?
If you plant a bulb in the heat of July, it will likely sit dormant in the soil. The biggest risk is that the combination of high soil temperatures and summer watering can cause the bulb to rot before it ever has a chance to grow roots. It is much safer to store the bulb in a cool, dry place and wait until the autumn to plant it.
I dug up my daffodils in June; can I move them now?
Yes, if you are lifting and dividing established daffodils from your own garden, you can move them in the early summer. This is best done as the foliage is yellowing. Replant them immediately at the same depth they were before, but avoid overwatering the area during the rest of the summer while the bulbs are dormant.
Should I keep my daffodil bulbs in the refrigerator during the summer?
In most parts of the country, a cool basement or garage is sufficient for summer storage. Gardeners in very warm climates (Zones 8-10) may need to "pre-chill" certain bulbs in the refrigerator for 10-15 weeks before planting, but this usually happens in the fall, not the middle of summer. If you use a fridge, keep the bulbs away from ripening fruit.
