- As winter fades, crocuses, daffodils, and tulips are among the first to bloom. These early spring flowers, along with other underground growth structures like tubers, rhizomes, and corms, are ready to sprout as soon as the weather warms up.
- When planted in suitable locations, daffodils, snowdrops, and crocuses form large clusters that brighten the landscape with their early blooms. Tall tulips and daffodils also make excellent cut flowers for indoors. Hyacinths, dwarf irises, and certain daffodils offer delightful fragrances, making them enjoyable both indoors and outdoors.
- Summer comes alive with the vibrant colors of summer-blooming bulbs like caladiums, dahlias, cannas, and gladioli. These bulbs thrive in warmer climates and won’t survive freezing temperatures. However, they can be dug up, stored during winter, and replanted when the weather warms again. While other plants take a break from the heat, summer bulbs continue to flourish, offering an abundance of blooms perfect for making beautiful bouquets.
In the next section, we’ll share some useful tips for working with bulbs throughout the year.
Choosing Bulbs
When buying bulbs, always choose healthy ones. Think of it as shopping for good-quality onions in the store.
- Look for firm bulbs, free from soft spots or dark, diseased areas.
- Examine the basal plate, where the roots will grow. It should be sturdy and undamaged.
- Daffodil bulbs with two noses will yield double the blooms, but tulips should only have one. If a tulip bulb has two, it won’t flower properly.
- Consider pooling bulb orders with friends to buy in bulk and save money. One catalog offers 100 tulip bulbs for just a bit more than 50. Ordering early guarantees the best selection and timely delivery.
Working with Plant Bulbs All Year Round
Store bulbs for the winter in a plastic storage container.Bulbs can bloom from early spring to late summer, but they need consistent care throughout the year. The following tips will help ensure your bulbs stay healthy no matter the season.
Spring-Blooming Bulbs
- Plant spring-blooming bulbs to infuse early color into otherwise bare perennial beds. While perennials are still waking up, the bulbs burst into color. As the bulbs fade, the perennials begin to thrive. This makes for a perfect seasonal combination.
- Plan ahead for the best placement of bulbs among perennials. Although spring bulbs bloom early, they must be planted in the fall. They look their best in clusters, nestled around or between perennials such as hardy geraniums, daylilies, and Siberian irises that don’t require frequent division (which could disturb the bulbs).
Working with Dahlia Rhizomes
- In the spring, take the dahlia rhizomes out of storage. Cut the crown into several sections, each with at least one rhizome and a growth bud. Each piece can now grow into its own independent plant. Divide your dahlias every year to increase your collection of plants.
- Dahlias contain underground rhizomes, which are modified stems that resemble potatoes. These rhizomes connect to a central, stalk-like crown that holds all the growth buds. Look for small scaly bumps or sprouts on the rhizomes, as they indicate where new shoots will emerge. Both rhizomes and shoots are necessary for a successful new division.
- Start dahlias indoors six weeks before the last frost of spring to enjoy flowers even earlier. Plant the tubers in large nursery pots filled with compost-enriched peat-based potting mix. Keep the pots in a warm, bright area. As the plants begin to root and sprout, they can remain in the large pots throughout the summer if the soil stays moist and you provide extra fertilizer. Alternatively, transplant them outdoors after the danger of spring frosts has passed.
Planting Fall Bulbs
- Don't wait until the bulbs arrive in October. In spring or summer, mark your ideal planting locations with a tag or stake while your current bulbs are blooming and the perennial clumps are still small. By the time autumn arrives and perennials are dormant, your perfect planting spots will already be marked.
- Mark the locations of your bulbs with a stake, stick, rock, or tag so you’ll know where they are when they’re dormant. Without an above-ground marker, you may accidentally dig into your bulbs while planting other flowers or clearing weeds.
Preparing for the Cold Winter Months
- Before the first fall frost, dig up tropical bulbs like cannas and caladiums to protect them from cold damage. Bulbs that are damaged are more likely to rot during winter storage. Cold-tolerant bulbs such as dahlias and gladiolus should be dug up after a light frost has killed the foliage. When digging, aim the shovel blade straight down into the soil (not the handle) to avoid slicing nearby bulbs in half.
- Cover large bulb patches with a ground cover that will fill the space when the bulbs go dormant. The bulbs will brighten the ground cover in spring, while the cover helps keep the bulbs cool and dry during summer. You may need to fertilize more often since you'll have twice the number of plants growing in the same area.

Storing Bulbs Through the Winter
To store bulbs during the winter, you need a proper storage container. A plastic box filled with vermiculite or peat will work perfectly.
- Place the bulbs in the peat or vermiculite, ensuring that they are about an inch or two apart from one another.
- Use one type of bulb per box or layer, and make sure to label each layer so you can easily identify them in the spring.
- Cover the bulbs with a generous layer of peat or vermiculite, then add another batch of bulbs, repeating the process until all bulbs are packed.
- Keep the bulbs in a cool but not freezing location during the winter months.
- Check the bulbs at least once a month, preferably more often. Remove any bulbs that may have rotted. If the bulbs begin to shrivel, lightly moisten the packing material to prevent further dehydration.
How to Display Bulbs in Your Garden
Planting bulbs in a deeper nursery pot results in a stunning display.Bulbs blossom into colorful flowers. Here are some imaginative ideas for showcasing these vibrant plants in your garden:
- Try planting a triple-layer bulb arrangement in your garden. Start with a top layer of early-blooming flowers like crocuses, snowdrops, or squills for an early spring splash of color. Beneath them, plant daffodils at a depth of 5 or 6 inches to bloom in mid-spring. For a final flourish, plant late-blooming tulips underneath, as they thrive in deeper soil. You can also replicate this layered planting style in a large pot for an early color burst.
- Revive dull corners of your garden with pots filled with tender bulbs such as agapanthus, tuberous begonias, caladiums, pineapple lilies, or tuberoses. The combination of the mobility of pots and the bright blooms from summer-flowering bulbs ensures your garden stays vibrant throughout the summer and into fall.
- Create a double flower display by planting Paper White narcissus bulbs. These bulbs, with their sweet-smelling clusters of small white daffodil-like flowers, are perfect for warmer climates and naturally bloom in winter. Plant them in late fall or early winter, and enjoy watching them bloom in a sunny window, even while snow falls outside.
- Group daffodils of the same cultivar together in large clusters of 10, 20, or more. This way, all the flowers will bloom at once, creating a powerful visual impact in the same color. A few daffodils can appear isolated, while a mix of different colors and cultivars can seem disorganized.

Tips for Caring for Bulbs in Your Garden
Trimming a lily stem helps prevent the risk of stem rot.Bulbs are distinct plants that require particular care and gardening techniques. The following suggestions will help you cultivate vibrant, healthy flowers:
Feeding and Dividing Bulbs
- Before planting fall bulbs, soak them in warm water for 12 hours. This hydration method works well for tunicate bulbs (those with a tight, smooth coating) but should not be used with lilies or other bulbs that have loose, fleshy scales. The soaking helps these bulbs absorb enough water to kickstart their growth, allowing them to begin sprouting right away and saving two or three weeks. This technique is especially beneficial in colder climates where early winter weather can shorten the growing season.
- If your daffodils are becoming too crowded, divide or fertilize them to promote better blooming. Over time, a large cluster of daffodils can exhaust the soil nutrients and fill up the available space, leading to abundant leaves but few flowers. A simple solution is either adding fertilizer or dividing the bulbs.
- For healthy root development, apply fertilizer. Slow-release bulb fertilizers can be used in the fall to support root growth and will remain effective into early spring. Alternatively, you can apply a balanced, all-purpose fertilizer when new growth starts in the spring.
- To divide daffodils, wait until the foliage begins to fade, then carefully dig up the bulbs. Separate the old and new bulbs, enrich the soil with organic matter, and replant with plenty of space between each bulb for optimal growth.
Pruning New Plants for Growth
- Harvest the bulbils from lily stems and plant them to grow new lilies. These bulbils, small bulb-like structures that resemble dark berries, contain no seeds but have the potential to sprout into full-grown plants. Treat them like miniature bulbs and give them the opportunity to flourish.
- In fall, cut lily stems back to the ground to prevent stem rot. It’s always safer to take action now than regret it later!
- Allow bulb foliage to remain loose and ripen naturally. Cutting the leaves prematurely, before they turn yellow, cuts off the food supply to the bulb and weakens it. Tying up daffodil leaves restricts their ability to produce food, which also makes them vulnerable to disease. Taking care of bulb foliage, even after flowering, is essential for a more abundant bloom in future seasons.
- After tulip flowers have faded, cut their tall stems back to the first leaf. This process, known as deadheading, removes the spent flower but leaves the healthy foliage to ripen in the garden, helping nourish the plant for future blooms.
Storing Delicate Bulbs
- Store tender bulbs in a bed of vermiculite or peat to prevent them from drying out. These materials act as a protective cushion and more, keeping the bulbs hydrated and preventing rot. Peat moss, known for its natural resistance to diseases, is especially effective in this process.
- When digging up bulbs, wait until the soil is fairly dry to avoid clumping them in mud. Gently remove excess soil and clear away any decayed plant matter. Discard any bulbs that show signs of damage.
In the next section, we will discuss how to protect your bulbs from rodents and disease.
Bulbs and Ground Covers
Choose bulbs and ground covers based on factors such as height, strength, and leaf density.
- Bulbs with fragile stems may struggle to emerge through dense-leaved ground covers like pachysandra. For these bulbs, consider using ground covers with finer leaves and more space between them, like periwinkle.
- For bulbs to thrive, they need to be tall enough to push through any surrounding ground cover. For shorter, early-blooming species like crocuses, consider pairing them with deciduous ground covers like epimedium, which die back each winter, rather than with evergreen covers like ivy.
Protecting Your Bulbs from Disease and Rodents
Ensure your bulbs are planted in soil that drains well to promote healthy growth.Rodents and plant diseases can be significant threats to your garden. Use these strategies to keep them from damaging your bulbs:
- Help your bulb plantings thrive by preventing disease and minimizing competition for nutrients. Always use well-drained soil to avoid bulb rot. Fertilize in the fall with a bulb-specific product, ensuring that the plants won't have to compete for resources. Water generously in spring when the bulbs are growing, but let the soil dry out in summer when they are dormant.
- Plant tulips 8 to 10 inches deep to extend their lifespan and keep them safe from rodents. When planted deeply, tulips take longer to split and stop flowering. Plus, they require significant effort for rodents to reach, offering an effective deterrent. It's a win-win!
- Protect your crocuses and other bulbs from rodents by planting them in fine-mesh or chicken wire baskets. If the animals can't dig them out, they won't be able to eat them. The wire cages also help prevent unintentional damage from gardening tools like shovels and hoes.
- For added protection, mix liquid rodent repellent with your bulb-soaking water (at the lowest recommended concentration). This will make the bulbs unappealing to rodents. The bitter taste absorbed by the bulbs deters mice, chipmunks, rabbits, raccoons, skunks, and many other animals. This method works especially well for crocuses and other shallowly planted bulbs that are vulnerable to being unearthed and eaten.
