It can be tempting to cram daffodil or tulip bulbs into every available space in the yard as the frost of October ushers in bulb planting season and visions of a brilliant spring.
But Doris Taylor, a plant information specialist at The Morton Arboretum Plant Clinic, advises caution before planting bulbs around a tree.
Taylor claims that the area is too shaded for many bulbs to flourish. You should also keep your digging and root-slicing to a minimum for the sake of the tree.
Large, hefty bulbs like hyacinths and tulips should be planted in sunny locations far from trees. Choose plants with smaller bulbs for the area beneath a tree’s branches to cause the least amount of harm to the tree’s roots.
So that you just need to dig among the tree’s roots once to enjoy a spring show for years to come, you’ll also want spring-blooming bulbs that will live a long time and rebloom every year.
Early bloomers, which flower before the tree fully extends its awning of leaves, are your best choices. Taylor proposes crocuses, Siberian squills (Scilla siberica), snowdrops (Galanthus nivalis), glory of the snow (Chionodoxa forbesii), and tiny early irises like Iris reticulata or I. danfordiae. Plant a lot of them, she advises. “A good display requires a lot of tiny bulbs,” someone once said.
The majority of spring-blooming bulbs demand full sun, although several varieties, like the Siberian squill, striped squill, checkered fritillary, and Spanish bluebells (Hyacinthoides hispanica), can withstand some partial shade. Daffodil species that bloom early may also thrive in the shade of trees.
Taylor asserts that “bulbs need well-drained soil.” Plant the bulbs with the flat (root) end down and the pointed (stem) end up. Set the bulb on its side if you’re unsure; the plant will rise to the surface.
Because the bulbs won’t be very wide, you only need to plant them about three inches deep. Dig a hole that is three times as deep as the bulb is wide as a general rule. Avoid large tree roots by carefully digging with a narrow trowel or garden knife. or use a dibble, a pointed instrument designed to make holes in the ground. After planting, water thoroughly and apply a layer of mulch.
There is no need to add bone meal or any other fertilizer at planting because the soil in the Chicago area typically contains a plenty of phosphorus. After flowering, bulb plants need fertilizer so they can create the bulbs for the following year.
If you choose and plant your spring bulbs carefully, you’ll be able to appreciate the beauty of both your springtime flowers and the summertime shade of your tree for many years to come.
Can bulbs be planted beneath trees?
Planting flower bulbs beneath garden trees gives off a lovely aesthetic. However, it is not always successful to plant any bulbs beneath enormous trees due to the strong shadow provided by the trees, competition with their roots, and lack of moisture under these trees. A tree always prevails when competing with bulbs for nutrients, water, or light.
Planting for success – Give your bulbs a chance to survive and bloom
- Plant your bulbs beneath evergreens. Planting them under evergreen trees will prevent them from receiving enough light to develop and bloom.
- Make sure your trees (oaks, redbuds, hawthorns, and southern magnolias) have deep root systems or lots of surface roots, as well as tall limbs (casting light shade). Avoid trees with branches that are too close to the ground or with shallow or fibrous roots (such as sugar maples) (casting too much shade)
- Plant bulbs that bloom early; they will blossom before the tree’s leaf canopy has fully extended.
- Plant fall-blooming bulbs, such as autumn crocuses, to brighten shaded regions beneath trees at a time when few other bulbs are in bloom in the garden.
- Plant bulbs that grow in wooded regions tend to do so because some of them are acclimated to partial sunlight or even complete shadow.
- Plant perennial bulbs that grow naturally, so you only need to dig among the tree’s roots once to enjoy a spring display for years to come.
- Plant a lot of them because a spectacular display requires a lot of little bulbs.
Snowdrops (Galanthus), crocuses (Crocus), grape hyacinths (Muscari), winter aconites (Eranthis), Siberian squills (Scilla siberica), snowflakes (Leucojum), bluebells (Hyacinthoides), early flowering daffodils (Narcissus), and many other lovely perennial bulbs grow nicely under trees.
They all appear magnificent as they make a carpet of flowers that dance in the filtered light beneath a stand of trees. As long as they receive the ideal lighting conditions and are planted in soil with the right drainage, they will emerge from the ground year after year and some will even slowly reproduce.
Can I spruce up a tree with spring bulbs?
In the areas where the tree roots killed the grass or where gardeners purposefully eliminated the competition, many trees have rings of bare mulch surrounding them. (Tree roots do not enjoy grass competition any more than grass does not mind tree roots’ shade and competition.) Most bulbs can offer necessary color in spring and thrive fairly well in dry shade under trees. For at least a few years, bulbs often receive enough sunlight to “recharge before the trees leaf out.” The bulbs go dormant when the trees produce shade and reach their peak moisture-using season; in fact, they prefer the dryness of the summer. Some of the greatest flowers in this environment include dwarf daffodils, Siberian squill, grape hyacinths, crocuses, and glory-of-the-snow. Plant new ones if they start to dwindle or cease blooming in a few years as a result of the competition from the trees. Put a few pots of shade annuals under the trees, or plant annuals like begonias, coleus, or nasturtium that can withstand dry shade and root competition.
Where can daffodils be planted most successfully?
- After plants stop blooming, let daffodil leaves naturally fade back.
- If daffodils get too crowded and cease flowering, divide them.
Without daffodils, no spring garden is complete. Furthermore, they are frequently the only plants blooming in the garden in the early spring, so you really can’t have too many of them. Since daffodils are perennial plants, they return year after year and are among the easiest spring flowering bulbs to raise.
How to Choose Daffodils
The majority of daffodil cultivars grow best in milder climates because they need a period of cold weather each winter to encourage blooms for the following spring (zones 7 and lower). However, there are some types that thrive in warmer climates (zones 8 and higher), and bulb catalogs will always include them. There are numerous daffodil types available.
Daffodils come in all sizes, including some with enormous blossoms. Bulbs with peach, orange, yellow, pink, white, or bicolor flowers are available to purchase. There are season-specific early, mid, and late bloomers. You may enjoy three months of daffodil blossoms with careful planning! Even 100-day mixtures of bulbs are available in some stores, making it simple for you to take advantage of an extended daffodil season.
Where to Plant Daffodils
Daffodils should be planted in a sunny area that receives at least 6 hours of direct sunlight each day. The plants won’t blossom if they are planted in partial shade, but they will still produce green leaves. Daffodils, like the majority of bulbs, demand well-drained soil; otherwise, they are susceptible to rotting.
When to Plant Daffodils
Fall is the ideal season to plant daffodil bulbs (exact timing can range anywhere from September to late November, depending on where you live). When you plant, the earth must still be usable but the soil must have cooled. Daffodil planting requires soil that is 60 degrees Fahrenheit and 6 inches deep.
How to Prepare the Soil for Planting Daffodils
Mix 3 inches of Miracle-Gro Garden Soil for Flowers into the top 6 to 8 inches of the existing soil to prepare new planting sites. As a result, bulbs will receive the nutrition they require to develop a sturdy root system in time for spring blossoming.
How to Plant Daffodils
Daffodils can be planted singly, in groups (3 or 5 is a good number), or in rows. It is simpler to dig a trench or a large planting hole if you are planting many bulbs in a row along the edge of a flowerbed. You should plant them individually if you’re randomly putting them in a flowerbed or on the grass. The spacing between bulbs, regardless of how many you plant, should be 4 to 6 inches.
Each daffodil bulb should be planted with its pointed end (or tip) facing upward. When the bulb is inserted, dig the hole or trench so that the tip is 2 inches deeper than the bulb’s height. Therefore, a 2-inch long bulb should be planted 4 inches deep, while a 3-inch long bulb should be planted 5 inches deep (measured from the bottom of the bulb). After planting, give the soil plenty of water, and then add a layer of mulch to keep the area looking neat and to help the soil hold moisture longer.
How to Water Daffodils
Daffodils should be well watered at planting time and then once per week throughout the following three weeks. (Watering is essential at this period since the plants are developing their first roots.) After the first few weeks, don’t disturb the plants again until the spring, when they’ll start to grow.
When you notice daffodil leaves poking through the ground, it’s time to focus once again. While daffodils are growing and blooming, water the plants if your area doesn’t get any rain for two or three weeks. Spring storms typically supply enough of moisture. Once the blossoms have faded and the foliage starts to turn brown, stop watering because this signals the start of a time of dormancy and too much water might cause the bulbs to rot.
How to Feed Daffodils
A powerful combination of excellent soil and the ideal plant nourishment produces stunning garden outcomes. So, to aid the bulbs in storing nutrients for the following growing season, feed daffodils with Miracle-Gro Shake ‘n Feed Rose & Bloom Plant Food after they have blossomed in the spring. Feed as directed on the label every three months, and once the foliage turns brown, cease feeding.
What to Do with Daffodils After They Bloom
Daffodil plants will be prompted to focus energy back into the bulb rather than setting seed if wasted blooms are removed after blooming. (This method is known as deadheading.) After the plant has finished blooming, keep the leaves upright and unfolded so that the plants can use photosynthesis to produce and store food for the next spring’s blossoms. Before you do any trimming back, let the leaves naturally die down. If you want to create a screen around the daffodils if you don’t like how the foliage is beginning to turn brown, consider planting late-emerging perennials.
How to Divide Daffodils
Daffodils need to be divided in the fall if they are in full sun, have been allowed to naturally die back the previous spring, and are not flowering when they need to. Each spring clump that needs to be divided should have a golf tee placed next to it so that when they die back, you can easily locate them. Break separate the bulbs in each clump and excavate it. The biggest bulbs should be replanted at least two bulb widths apart. (When dividing, little bulbs might remain affixed to larger bulbs.) As if you were planting new bulbs, prepare the soil.

Can you grow daffodils in the shade?
Most bulbs, including tulips, require lots of sunlight from the time they emerge from the ground in the early spring until their foliage turns yellow and collapses in order to grow and flower successfully. Although daffodils can withstand some shade, they might not bloom the next year if they receive less than half a day of direct sunlight. Even for sun-lovers like tulips, a little midday shade in warm climes can be beneficial for extending bloom and preventing flower colors from fading.
The following bulbs can thrive in filtered sunlight under deciduous trees or with just a half-day of direct sunlight. But beware—no bulb will grow well in complete darkness.
Which bulbs can I grow beneath trees?
Best ten bulbs for shade
- Snowdrops. Snowdrops are perfect for a partially shaded or woodland-style garden because of their native woodland habitat.
- Anemones. Anemones, another essential plant for a woodland garden, can cover those drab, shaded regions in a carpet of blossoms.
- Fritillaria.
- Crocus.
- Narcissus.
- Muscari.
- Scilla.
- Eranthus.
Do daffodils blossom beneath oak trees?
Garry oak, often known as Oregon white oak, is a challenging tree to grow under since it cannot withstand the summer irrigation that many other plants need. The native to the Northwest is more susceptible to illness and an early death during the summer.
The appropriate remedy was discovered by C. Ivan Vistica, who lives close to Woodburn, Oregon. He underplants his white oaks with drifts of daffodils. They bloom two months prior to the deciduous oaks turning leaves and beginning to cast shadow. The daffodils and oaks don’t require any more summer water. Daffodils actually have the best chances of naturalizing if the foliage is allowed to wither and the bulbs are allowed to dry out in the summer.
Around 1990, Vistica began this planting with double-flowered daffodils that had already taken root all over his farm. He moved them beneath the oaks, setting the bulbs in rows that were nine inches apart and spaced approximately seven inches apart. He never fertilized them; he simply mulched them with oak leaves.
Daffodils should be planted in the fall, but now is a good time to look at flowering varieties to see which ones you prefer.
Can you plant bulbs in the shade?
After their flowering season is through, spring bulbs progressively lose their color before going dormant until the next year. They are therefore the perfect companions for perennials that thrive in shade and bloom from early summer to late fall. The fading leaves of the spring bulbs are hidden by the perennials’ growing foliage.
Small spring bulbs like Snowdrops, Crocus, Scilla siberica, and Chionodoxa are perfect for planting in shaded locations at the foot of shrubs, underneath big shade trees, and along woodland walks. They bloom first among all bulbs, and their foliage fades away soon. These little bulbs will grow in number over time, adding colorful accents to your yard.
In flowerbeds where you may also be growing annuals like impatiens, begonias, and caladiums, tulips are an excellent choice. Simply take out the tulips once they have flowered and plant the annuals in their place. Take out the annuals in the fall and plant new tulip bulbs.
Almost every variety of garden perennial is suitable with bulbs that bloom in the spring. The following combinations have shown to be highly successful:
