Introduction
The sight of the first bright yellow daffodil is a highlight for many gardeners. These cheerful blooms are the ultimate sign that winter is over and warmer days are ahead. Because they bring such joy, it is natural to want to get them into the ground as soon as you think of them. If you are browsing garden centers or planning your landscape during the warmer months, you might find yourself wondering if you can plant these daffodil bulbs during the summer.
At Longfield Gardens, we want to help you achieve the best possible results with your spring-blooming bulbs. Understanding the natural rhythm of a daffodil is the secret to a garden full of vibrant color. While summer is an excellent time for planning and even moving some established plants, it is usually not the time for planting new, dormant bulbs. This article will explain why timing matters and how you can use the summer months to prepare for a spectacular spring display.
We will cover the lifecycle of the daffodil, the risks of planting too early, and the specific situations where summer handling is actually beneficial. Whether you are a beginner or an experienced gardener, this guide will help you understand the simple steps for success. In most cases, the best approach is to let the bulbs rest through the heat and wait for the cooling soil of autumn.
The Short Answer: Should You Plant in Summer?
In the world of gardening, timing often beats complex tricks. For most gardeners in the United States, the answer to whether you should plant new daffodil bulbs in the summer is a gentle "not yet." To get the best results, dormant daffodil bulbs should be planted in the fall. This is when the soil temperature begins to drop, providing the perfect environment for root development without the risk of the bulb rotting in the summer heat.
If you were to put a dormant bulb in the ground during July or August, it would likely encounter two main problems: excessive heat and too much moisture. These conditions can cause the bulb to rot before it ever has a chance to grow. Additionally, daffodils need a period of cold weather, known as vernalization, to trigger their flowering process. Planting in the summer would leave them sitting in warm soil for far too long.
However, there is a small exception. If you are moving existing daffodils that are already in your garden, early summer is actually a great time to dig and replant them. This is often called "planting in the green" or "moving while dormant." We will explore how to do this correctly later in this guide. For new bulbs you have purchased, your best bet is to store them safely until the autumn air turns crisp.
Understanding the Daffodil Lifecycle
To understand why summer planting isn't ideal, it helps to look at what the bulb is doing throughout the year. A daffodil bulb is more than just a seed; it is a self-contained storage system. Inside that brown, papery skin is everything the plant needs to grow, including the embryonic flower and a supply of food.
Spring: Growth and Bloom
In early spring, the bulb uses its stored energy to push green leaves and colorful flowers above the soil. This is the most active phase. During this time, the leaves are working hard to gather sunlight. They turn that light into energy through photosynthesis, which is then sent back down into the bulb to recharge it for next year.
Early Summer: Recharging and Dormancy
As the flowers fade, the leaves stay green for several weeks. This "recharge" phase is critical. Eventually, the foliage will start to turn yellow and then brown. This is the plant’s way of saying it has finished its work for the season. Once the leaves are completely yellow and pull away easily from the ground, the bulb enters a state of dormancy. Dormancy means a period of rest when the plant is not actively growing.
Late Summer: The Rest Period
During the heat of late summer, the bulb is resting deep underground. It is protected from the sun by the soil above it. It does not want to be disturbed or exposed to high levels of moisture during this time. In nature, the soil usually dries out somewhat in the summer, which keeps the dormant bulb healthy and prevents fungal issues.
Fall: Root Development
When the temperatures drop in the fall, the bulb wakes up from its rest. It begins to grow a new root system. This is why we plant in the fall—the cool soil encourages roots to grow, but the air is too cold to encourage the leaves to sprout. Strong roots are the foundation for a healthy bloom the following spring.
Why Summer Planting Can Be Risky
The main reason to avoid planting dormant bulbs in the summer is the risk of rot. Most spring bulbs, including daffodils, are very sensitive to a combination of high heat and wet soil. In the summer, many gardeners are regularly watering their flower beds or vegetable gardens. If a dormant bulb is buried in a spot that receives frequent summer water, it may fall victim to "basal rot," which is a fungal infection that turns the bulb into mush.
Another factor is soil temperature. For a daffodil to begin growing roots, it usually needs the soil to be around 60°F or cooler. In many parts of the U.S., summer soil temperatures can climb much higher than that. If a bulb is planted in hot soil, it may try to sprout prematurely if the weather is weird, or it may simply sit there and decline in quality.
Key Takeaway: For the best results, match the planting time to the plant's natural rhythm. Daffodils prefer to be planted when the soil is cooling down, not when it is at its hottest.
Moving Established Daffodils in Summer
While you shouldn't plant new bulbs in the summer, this is actually the perfect time to move or divide the daffodils you already have. If your daffodil clumps have become too crowded and aren't blooming as well as they used to, summer is your window of opportunity.
When to Dig
Wait until the foliage has turned mostly yellow. This ensures the bulb has finished storing all the energy it needs for next year. Usually, this happens in June or early July depending on your location. Because the leaves are still visible, you can easily see where the bulbs are located, which prevents you from accidentally slicing through them with a shovel.
How to Divide
Gently dig around the clump with a garden fork or spade. Lift the entire mass of bulbs out of the ground. You will likely see one large parent bulb with several smaller "offsets" or baby bulbs attached to the sides. You can gently pull these apart with your hands.
Replanting Immediately
Unlike new bulbs purchased from a store, these "fresh" bulbs can be replanted immediately. Even though it is summer, they are already acclimated to your local soil and climate. When you replant them, follow these simple steps:
- Choose a sunny spot with good drainage.
- Dig a hole about 6 inches deep.
- Place the bulb with the pointy end facing up.
- Cover with soil and walk away—do not water them excessively throughout the summer.
How to Store Bulbs Until Fall
If you find yourself with a bag of daffodil bulbs in the middle of summer—perhaps you bought them on clearance or received them as a gift—do not feel pressured to put them in the ground immediately. They will be much happier if you store them properly until the fall.
The goal of storage is to keep the bulbs cool, dry, and dormant. Follow these steps to keep your bulbs in prime condition:
- Remove from plastic: If the bulbs came in a plastic bag, take them out immediately. Plastic traps moisture and can cause mold.
- Use breathable containers: Place the bulbs in a mesh bag (like an onion bag), a paper bag, or a shallow cardboard box. This allows air to circulate around them.
- Find a cool, dark spot: A basement, a garage, or a dark pantry is usually a good choice. You want a place that stays relatively cool but is not damp. Avoid keeping them in a spot that gets direct sunlight or near a heating vent.
- Keep them away from fruit: This is a lesser-known tip, but very important. Do not store your bulbs in a refrigerator near ripening fruit like apples or pears. These fruits give off ethylene gas, which can damage the flower bud inside the bulb.
- Check them occasionally: Every few weeks, take a quick peek at your bulbs. If you see one that looks mushy or has heavy mold, throw it away so it doesn't affect the others. A little bit of surface dust or "tunic" (the papery skin) peeling off is perfectly normal.
Planning Your Summer Bulb Order
Summer is the ideal time to browse for varieties and place your orders. Many gardeners use this time to reflect on what their garden looked like in the spring. Did you have a gap under the oak tree? Would a splash of white look better near the front porch?
When you order from us at Longfield Gardens during the summer, you are essentially "reserving" your favorite varieties. We work with trusted growers to ensure we provide premium bulbs that are true to their variety. Because we want you to succeed, we do not ship bulbs during the heat of the summer. Instead, we coordinate our shipping schedule with the USDA hardiness zones.
Your order will arrive at the right time for planting in your specific area. This usually means your bulbs will show up about two weeks before the ideal planting window in your zone. This takes the guesswork out of the process, ensuring you receive fresh bulbs that haven't been sitting in a hot warehouse or a retail shelf for months.
If you want to see how that timing works in practice, our Shipping Information page explains how we schedule deliveries by zone.
Choosing Varieties in Summer
While you are planning, consider the different types of daffodils available. Choosing a mix can extend your bloom season:
- Early-season: Varieties like Tete a Tete or 'Rijnveld's Early Sensation' can bloom while there is still snow on the ground.
- Mid-season: This is when the classic large-cupped yellow daffodils and Dutch Master types usually shine.
- Late-season: Fragrant varieties like 'Pheasant's Eye' or multi-flowered types often bloom when the tulips are in full swing.
If you are planning a bigger display, the Daffodil Cyclamineus Tete a Tete - Bulk Offer and Daffodil Trumpet Dutch Master - Bulk Offer are useful options for larger plantings.
Site Selection: Preparing for Fall Success
Since you have the summer to prepare, take a look at your garden and find the best locations for your future daffodils. Getting the "right plant in the right place" is one of the most important rules for gardening success.
Sun Requirements
Daffodils love the sun. For the best blooms, choose a spot that gets at least six hours of direct sunlight per day. One of the great things about daffodils is that they can often be planted under deciduous trees (trees that lose their leaves in winter). Because the bulbs bloom and finish their growth before the trees are fully leafed out, they can get the sun they need before the shade sets in.
Drainage is Key
"Drainage" is a word gardeners use to describe how fast water leaves the soil. Daffodils must have well-draining soil. They do not like "wet feet." If you have a spot where puddles stand for hours after a rain, that is not the place for daffodils.
- For heavy clay soil: You can improve drainage by adding organic matter like compost or by planting in raised beds.
- For sandy soil: Sandy soil drains very quickly. You may need to plant your bulbs slightly deeper to keep them cool and moist during their spring growth.

Space to Grow
Daffodils are perennials, which means they come back year after year. They also "naturalize," or spread, over time. When planning your spot in the summer, make sure you leave enough room for the clumps to expand. A good rule of thumb is to plant them 4 to 6 inches apart. This gives them space to grow for several years before they become crowded.
The Importance of Soil Temperature
As summer fades into fall, the most important thing to watch is the temperature of your soil. Many people make the mistake of planting as soon as the first cool day of September arrives. However, the soil holds onto heat much longer than the air does.
Wait until the soil temperature is consistently 60°F or below. A simple way to check this without a thermometer is to wait until the nighttime temperatures are regularly in the 40s or 50s for about two weeks. In the northern states, this might be in late September or October. In the southern states, this could be as late as November or even December.
Planting when the soil is cool ensures the bulb stays dormant until it is ready to grow roots. It also protects the bulb from those soil-borne fungi that thrive in warm, wet conditions.

Summary of Summer Tasks for Daffodil Lovers
Even though you aren't putting new bulbs in the ground, summer is a productive time for a daffodil gardener. Here is what you should focus on:
Action List for Summer:
- Monitor foliage: Wait for spring leaves to turn yellow before cutting them back or digging bulbs.
- Divide and transplant: Move crowded clumps in early summer while the bulbs are dormant.
- Order early: Reserve your favorite varieties from us to ensure the best selection.
- Select your sites: Identify sunny, well-draining spots for your fall planting.
- Store correctly: If you have bulbs on hand, keep them in a cool, dry, and airy place.

Looking Ahead to Fall Planting
Once the heat of summer passes, you will be ready for the real fun. Fall planting is a relaxing and rewarding activity. Because you did the hard work of planning and site selection in the summer, the actual planting will be a breeze.
When your bulbs arrive from Longfield Gardens, try to get them in the ground within a week or two. If you have to wait, just keep them in that cool, dark spot you identified earlier. When you finally head out to plant, remember the simple rule: plant the bulb three times as deep as it is tall. For most standard daffodils, this means about 6 inches deep.
Drop the bulb in the hole with the pointy end up, cover it with soil, and give it a good drink of water to settle the earth. After that, nature will take over. The bulbs will grow their roots in the cool fall soil, sleep through the winter, and surprise you with a beautiful display when spring arrives.

A Note on Safety
While daffodils are beautiful and easy to grow, it is important to remember that all parts of the plant—including the bulb—are toxic if eaten. This is actually a benefit for many gardeners because it means deer, rabbits, and squirrels will usually leave them alone! However, if you have curious pets or small children, make sure to keep your unplanted bulbs out of reach. It is also a good idea to wear gloves if you have sensitive skin, as the sap from the stems can sometimes cause a mild itch.

FAQ
Can I plant daffodils in July?
It is not recommended to plant new, dormant bulbs in July because the soil is too hot and usually too moist, which leads to bulb rot. However, you can dig and immediately move existing daffodils in your garden during July once their leaves have turned yellow.
I found a bag of bulbs in my garage in August, are they still good?
Most likely, yes! Check the bulbs to see if they are still firm. If they feel solid and don't have heavy mold, they are healthy. Keep them in a cool, dry, airy place and wait until the soil cools down in the fall (usually October or November) to plant them.
Why do I see bulbs for sale in the summer if I can't plant them yet?
Many retailers begin selling bulbs in late summer to help gardeners plan and reserve their favorites. At Longfield Gardens, we allow you to order in the summer, but we hold the shipment until the appropriate planting time for your specific climate zone to ensure the bulbs stay fresh.
What happens if I plant daffodils too early in the summer?
If planted in the heat of summer, the bulbs may rot due to high soil temperatures and moisture. They might also try to sprout leaves prematurely if there is a cooling trend, which uses up the energy they need for spring flowers and can lead to frost damage later.
