Knowing when to plant surprise lily bulbs is the single most important factor for their success. Planting surprise lily bulbs at the right time ensures their magical mid-summer appearance, transforming dormant garden spaces into a spectacle of pink blooms seemingly overnight.
These unique flowers, also known as resurrection lilies or naked ladies, have a fascinating growth cycle. Their strap-like foliage emerges in spring, dies back, and then the flower stalks burst forth in late summer without any leaves. To get this timing right, you need to plant the bulbs correctly.
This guide gives you everything you need to know. We will cover the ideal planting windows, step-by-step instructions, and essential care tips.
When To Plant Surprise Lily Bulbs
The best time to plant surprise lily bulbs is in late summer or early fall, immediately after they finish flowering. This period typically falls from late August through October, depending on your local climate.
Planting at this time allows the bulbs to establish their roots in the warm soil before winter arrives. The bulbs are also readily available from nurseries and garden centers during this post-bloom period. If you receive bulbs in spring, you can plant them then, but fall planting aligns perfectly with their natural biological clock.
The key is to get them in the ground while the soil is still workable and has some warmth. This gives them a head start for the following year’s growth cycle.
Understanding The Surprise Lily Growth Cycle
To truly grasp the best planting time, it helps to understand their unusual life cycle. Unlike most spring bulbs, surprise lilies operate on a delayed schedule.
In early to mid-spring, a cluster of long, strappy green leaves emerges from the ground. These leaves photosynthesize and send energy down to the bulb. By early summer, this foliage completely yellows and dies back, leaving the garden bed bare.
The bulb then lies dormant for several weeks. In late summer, usually around July or August, tall, leafless flower scapes shoot up from the bare ground in a matter of days. This is the “surprise.” After blooming, the bulb begins to set roots for the next year. This is why post-bloom fall planting is so effective—you are working with the bulb’s natural rhythm.
Fall Planting: The Ideal Window
Fall is the premier season for planting surprise lily bulbs. The goal is to plant about 6 to 8 weeks before your ground freezes hard. This provides ample time for root development.
You can use your local first frost date as a guideline. Aim to get your bulbs in the ground 2 to 4 weeks before that first frost is expected. The soil is still warm from summer, which encourages root growth, while the cooling air temperatures signal the bulb to begin its rooting process.
Here is a general regional breakdown for fall planting:
- Northern States (Colder Zones 3-5): Plant from late August to mid-September.
- Midwest and Mid-Atlantic (Zones 6-7): Plant from September to mid-October.
- Southern States (Warmer Zones 8-9): Plant from October through November, sometimes even into early December.
If you miss the fall window, you do have a secondary option, but fall remains the best choice for vigorous plants.
Spring Planting: A Secondary Option
Sometimes, you may acquire bulbs in the spring. Perhaps you ordered them online or a gardening friend divided their clumps. While not the ideal natural cycle, you can plant surprise lily bulbs in the spring.
Plant them as soon as the soil is workable, after the danger of a hard freeze has passed. The bulbs will produce their spring foliage on schedule. However, do not be disappointed if they do not flower that first summer. The bulb is focusing its energy on establishing itself and will likely bloom the following year.
Spring-planted bulbs need consistent moisture through their growing season to help them recover from storage and put down good roots. Mulching around them can help conserve this moisture and keep the soil cool.
What To Do With Bulbs Received Out of Season
If you get bulbs in winter or early summer, proper storage is crucial. Keep them in a cool, dry, and well-ventilated place. A paper bag in a garage or basement often works well.
Do not store them in plastic, as this can trap moisture and cause rot. Check on them periodically for any signs of mold or softening. Plant them at the very next appropriate planting window, whether that’s spring or fall.
Choosing The Right Planting Location
Surprise lilies are wonderfully adaptable but thrive best in specific conditions. Choosing the right spot is almost as important as nailing the planting time.
These bulbs need well-drained soil more than anything. They will rot if left sitting in soggy ground, especially over winter. They prefer full sun to partial afternoon shade. In hotter climates, a bit of shade during the hottest part of the day can prevent the flowers from fading too quickly.
Consider their unique growth habit when placing them. Since the area will be bare in late spring and early summer, plant them among perennials or ground covers that will fill in the space. Good companions include daylilies, hostas, or low-growing sedums that will cover the dying foliage but not overcrowd the emerging flower stalks.
Soil Preparation For Optimal Growth
Preparing your soil before planting gives your bulbs a major advantage. Start by loosening the soil to a depth of about 12 to 15 inches.
If your soil is heavy clay, amend it with compost or well-rotted manure to improve drainage. For very sandy soil, adding compost will help retain some moisture and nutrients. A simple soil test can tell you the pH; surprise lilies are tolerant but prefer a neutral to slightly acidic pH.
Incorporate a balanced, slow-release bulb fertilizer or bone meal into the planting hole or bed according to package instructions. This provides essential phosphorus for strong root development.
How To Plant Surprise Lily Bulbs Step-By-Step
Planting the bulbs correctly is straightforward. Follow these steps for the best results.
- Select Healthy Bulbs: Choose firm, plump bulbs without soft spots, cuts, or signs of mold. They often look like small, dark onions.
- Dig the Hole: Dig a hole that is about 6 to 8 inches deep. This depth is crucial for protecting the bulb from temperature extremes and providing stability for the tall flower stalk.
- Place the Bulb: Set the bulb in the hole with the pointed end (the neck) facing upward. If you cannot distinguish the top, plant the bulb on its side; the stem will find its way up.
- Spacing: Space bulbs about 8 to 12 inches apart. They look best planted in groups or drifts of at least 3 to 5 bulbs.
- Backfill and Water: Gently backfill the hole with soil, firming it lightly to remove large air pockets. Water the area thoroughly to settle the soil around the bulb.
- Mark the Location: Since the bulbs will be dormant, mark the spot with a plant label or small stake. This prevents you from accidentally digging into them later.
After planting, apply a 2-inch layer of mulch, such as shredded bark or straw, to insulate the soil, conserve moisture, and suppress weeds. In colder regions (zones 3-5), a thicker layer of mulch applied after the ground freezes can provide extra winter protection.
Caring For Surprise Lilies After Planting
Once planted, surprise lilies require minimal care, which is part of their appeal. Proper aftercare ensures they multiply and bloom reliably for years.
Watering: Water newly planted bulbs well. After that, they are quite drought-tolerant. Water only during extended dry periods in the spring when the foliage is growing and in the fall to support root growth. They generally do not need summer watering.
Fertilizing: Apply a balanced, slow-release fertilizer or a top-dressing of compost in early spring as the foliage emerges. This feeds the leaves, which in turn feeds the bulb for the coming bloom. Avoid high-nitrogen fertilizers, which promote leaf growth at the expense of flowers.
Managing Foliage: This is critical. After blooming, the bulb is already dormant. You must allow the spring foliage to die back naturally. Do not cut, braid, or remove the green leaves until they have turned completely yellow and brown. This process is how the plant stores energy for next summer’s surprise bloom.
Dividing And Transplanting Established Clumps
Over time, surprise lily bulbs will multiply and form large clumps. When flowering diminishes or the clump becomes overcrowded, it’s time to divide. The best time for this is the same as for planting: in the fall after the flowers fade or as the foliage dies back.
To divide, carefully dig up the entire clump with a garden fork. Gently separate the individual bulbs. You can replant the healthiest ones immediately at the proper depth and spacing. Share extras with friends or expand your own garden display. Division every 3 to 5 years is usually sufficient to maintain vigor.
Common Problems And Solutions
Surprise lilies are generally pest and disease resistant. However, a few issues can occassionally arise.
- Lack of Blooms: This is the most common complaint. Causes include planting too shallow, cutting foliage back too early, overcrowded bulbs, or insufficient sunlight. Ensure you follow the care guidelines for foliage and division.
- Bulb Rot: Caused by poorly drained soil. If bulbs rot, improve drainage in the bed before replanting. Raised beds are an excellent solution for areas with heavy clay soil.
- Aphids: Sometimes aphids may cluster on the flower buds or stalks. A strong spray of water from a hose is usually enough to dislodge them.
- Slugs and Snails: They may chew on the emerging flower scapes. Use organic slug bait or traps if damage is noticed.
Deer and rodents typically avoid surprise lily bulbs, making them a great choice for gardens where these animals are a problem.
Frequently Asked Questions
Can I Plant Surprise Lily Bulbs In The Spring?
Yes, you can plant surprise lily bulbs in the spring. Plant them as soon as the ground is workable. Be aware that spring-planted bulbs will produce foliage but may not bloom the first summer. They will use that season to establish themselves and should flower reliably the following year.
How Deep Should I Plant Surprise Lily Bulbs?
Plant surprise lily bulbs about 6 to 8 inches deep. Measure this depth from the base of the bulb to the soil surface. This depth provides insulation, stability for the tall flower stalks, and protects the bulb from being dug up by animals or frost heave.
Why Are My Surprise Lilies Not Blooming?
Several factors can prevent blooming. The most common reason is removing the spring foliage before it has yellowed completely. Other causes include planting too shallow, overcrowded bulbs that need dividing, excessive shade, or a lack of nutrients. Review your planting depth, location, and foliage care practices.
What Is The Difference Between Surprise Lilies And Other Lilies?
Surprise lilies (Lycoris squamigera) are not true lilies (Lilium species). They are part of the Amaryllis family. Their growth cycle is distinct, with foliage appearing in spring and flowers on bare stalks in late summer. True lilies typically have leaves on their flower stems and bloom in early to midsummer.
Can Surprise Lilies Be Grown In Containers?
They can be grown in containers, but it requires careful attention. Use a deep, large pot with excellent drainage. The container will need winter protection in cold climates, as potted soil freezes much harder than in-ground soil. You may need to move the pot to an unheated garage or insulate it. Container-grown bulbs will also need division more frequently.
