Choosing the Right Lily for Outdoor Planting: A Quick Guide
While most lilies can be planted outside, selecting the right type for your climate and garden conditions is key to success. Understanding the main divisions will help you make informed choices, ensuring your efforts result in a garden full of magnificent blooms. This is a crucial part of any comprehensive can lilies be planted outside guide.
Here are some popular lily classifications and what makes them unique for outdoor environments:
Asiatic Lilies
These are perhaps the easiest and most forgiving lilies for beginners. They come in a vast spectrum of vibrant colors, often with speckled throats, and bloom early to mid-summer. Asiatics are known for their upward-facing flowers and sturdy stems. They are not typically fragrant but are incredibly hardy and vigorous, thriving in USDA Zones 3-8.
Oriental Lilies
If you’re looking for fragrance, Oriental lilies are your go-to. Their large, often dramatic flowers bloom in mid to late summer and come in shades of white, pink, red, and bi-colors. They are incredibly popular for their intoxicating scent and classic beauty. While slightly less hardy than Asiatics, they generally do well in Zones 5-9.
Trumpet and Aurelian Hybrid Lilies
These majestic lilies boast large, trumpet-shaped flowers that can reach impressive heights. They are often highly fragrant, especially in the evenings, and bloom in mid-summer. Colors range from white and yellow to pink and orange. Trumpet lilies are hardy in Zones 4-9 and make a spectacular statement in the garden.
Tiger Lilies (Lilium tigrinum/lancifolium)
Recognizable by their recurved petals and prominent dark spots, Tiger lilies are incredibly tough and adaptable. They are unfussy about soil and light conditions, making them excellent for naturalizing. They bloom in mid to late summer and are hardy in Zones 3-9. A truly resilient choice for outdoor planting.
Martagon Lilies
Also known as Turk’s Cap lilies, Martagons feature many small, downward-facing flowers with recurved petals on tall, elegant stems. They are unique for their ability to tolerate partial shade and even some dry conditions once established. They bloom in early summer and are very long-lived, hardy in Zones 3-8.
How to Plant Lilies Outside: Step-by-Step Best Practices
Now for the exciting part: getting those beautiful bulbs into the ground! Proper planting is the foundation for healthy, flourishing lilies. Follow these steps carefully, and you’ll be well on your way to a spectacular display. This section focuses on the practical “how to can lilies be planted outside” aspects.
When to Plant
The ideal time to plant lily bulbs depends on your climate and when you acquire the bulbs. Generally:
- Fall Planting (Recommended): Planting in fall (6-8 weeks before the first hard frost) allows bulbs to establish roots before winter, leading to stronger plants and earlier blooms the following year. This is particularly good for most hardy varieties.
- Spring Planting: If you receive bulbs in spring, plant them as soon as the danger of hard frost has passed and the soil is workable. They will still bloom, but perhaps a little later than fall-planted bulbs.
Choosing Your Spot: Sun, Soil, Drainage
Lilies are generally sun-lovers, but they appreciate a little root shade. Think “sunny heads, cool feet.”
- Sunlight: Aim for a location that receives at least 6-8 hours of direct sunlight per day. Some varieties, like Martagons, can tolerate partial shade, especially in hotter climates.
- Soil: Lilies thrive in well-drained soil. This is perhaps the most critical factor. Heavy, waterlogged soil will lead to bulb rot. If your soil is clay-heavy, you’ll need to amend it significantly.
- Drainage Test: Dig a hole 12 inches deep and fill it with water. If it drains within an hour, you have good drainage. If it takes longer, you’ll need to improve your soil or consider raised beds.
Preparing the Soil: The Foundation for Success
Proper soil preparation is one of the most important can lilies be planted outside best practices.
- Amend Your Soil: Dig the planting area to a depth of at least 12-15 inches. Incorporate plenty of organic matter such as compost, well-rotted manure, or peat moss. This improves drainage in heavy soils and enhances moisture retention in sandy soils.
- pH Level: Lilies generally prefer a slightly acidic to neutral soil pH (6.0-7.0). A soil test can confirm your pH; amend with lime to raise it or sulfur to lower it if necessary.
Planting the Bulbs: Depth and Spacing
The exact depth can vary slightly by lily type, but a good rule of thumb is to plant bulbs two to three times as deep as the bulb’s height.
- Dig the Hole: Dig a hole deep enough for the bulb to sit at the correct depth, plus room for about an inch of sand or grit at the bottom for extra drainage.
- Add Drainage Layer: Place an inch or two of coarse sand or fine gravel at the bottom of the hole, especially if your soil isn’t perfectly drained.
- Position the Bulb: Place the lily bulb in the hole with the pointed end facing upwards.
- Backfill Gently: Cover the bulb with soil, gently firming it around the bulb to remove air pockets.
- Water Thoroughly: Water the area well after planting to settle the soil.
- Mulch (Optional but Recommended): Apply a 2-3 inch layer of organic mulch (shredded leaves, straw, or wood chips) over the planting area. This helps retain soil moisture, suppress weeds, and keep the roots cool, providing a sustainable advantage.
Spacing: Space bulbs 8-12 inches apart to allow for good air circulation and future growth. For a more dramatic visual impact, plant lilies in groups of three or five.
Essential Care for Outdoor Lilies: Ensuring Bountiful Blooms
Once your lilies are in the ground, a little ongoing care will ensure they flourish and reward you with stunning blooms season after season. Think of this as your “can lilies be planted outside care guide” to keep your plants happy and healthy.
Watering Wisdom
Lilies prefer consistently moist but not waterlogged soil. Especially during dry spells and when plants are actively growing and blooming, they’ll need regular watering.
- Deep Watering: Water deeply once or twice a week, rather than frequent shallow sprinklings. This encourages roots to grow deeper, making the plant more drought-tolerant.
- Avoid Overhead Watering: Try to water at the base of the plant to minimize moisture on foliage, which can help prevent fungal diseases.
Feeding Your Flowers
While lilies aren’t heavy feeders, a little nutritional boost can make a big difference.
- Spring Feed: In early spring, as new shoots emerge, apply a balanced, slow-release granular fertilizer (e.g., 5-10-10 or 10-10-10) around the base of the plants.
- Mid-Season Boost: You can apply a liquid fertilizer (half strength) when flower buds begin to form for an extra push, but be careful not to over-fertilize, as this can encourage leafy growth at the expense of flowers.
Staking Tall Varieties
Many Oriental and Trumpet lilies can grow quite tall, and their large blooms can make them top-heavy, especially after rain or in windy conditions. Staking prevents stems from bending or breaking.
- Stake Early: Insert stakes (bamboo canes or sturdy metal stakes) when plants are about a foot tall. This allows the plant to grow around the stake naturally.
- Gentle Ties: Use soft ties (like garden twine or fabric strips) to loosely secure the stem to the stake, allowing for natural movement and growth.
Deadheading for More Blooms
Deadheading—removing spent flowers—isn’t strictly necessary for lily health, but it can improve the plant’s appearance and direct energy towards bulb development rather than seed production.
- Pinch or Cut: Once a flower fades, you can pinch or cut it off just below the bloom, leaving the foliage intact.
- Leave Foliage: It’s crucial to leave the stem and leaves on the plant after blooming. The foliage is essential for photosynthesis, which recharges the bulb for next year’s blooms. Don’t cut the stem back until it naturally yellows and dies down in late fall.
Winterizing Your Lilies: Protection for Next Year
Most hardy lilies don’t require much fuss for winter, but a little protection can go a long way, especially in colder zones or during exceptionally harsh winters. These can lilies be planted outside tips ensure perennial success.
- Mulch: After the foliage has died back naturally in late fall, apply a 4-6 inch layer of organic mulch (straw, shredded leaves, pine needles) over the planting area. This insulates the bulbs from extreme temperature fluctuations and helps prevent frost heave.
- Remove Mulch in Spring: In early spring, gently pull back the heavy winter mulch as new growth emerges to prevent rot and allow the soil to warm up.
Troubleshooting Common Problems with Outdoor Lilies
Even the most experienced gardeners encounter challenges. Knowing how to identify and address common issues with your outdoor lilies will help you maintain a healthy, vibrant garden. Here are some of the common problems with can lilies be planted outside and how to tackle them.
Pests: Identifying and Controlling
-
Aphids: These tiny green or black insects cluster on new growth and flower buds, sucking plant sap.
- Solution: Spray with a strong stream of water, use insecticidal soap, or introduce natural predators like ladybugs.
-
Lily Beetles (Red Lily Beetles): These bright red beetles and their slug-like larvae can quickly defoliate lilies.
- Solution: Hand-pick adults and larvae regularly (they drop when disturbed, so place a container underneath). Dispose of them in soapy water. Neem oil can also be effective.
-
Slugs and Snails: They chew holes in leaves and can damage emerging shoots.
- Solution: Use slug baits, hand-pick them at night, or create barriers with crushed eggshells or diatomaceous earth.
Diseases: Prevention and Treatment
-
Botrytis Blight (Gray Mold): This fungal disease causes brown spots on leaves and flowers, especially in cool, wet conditions.
- Prevention: Ensure good air circulation, avoid overhead watering, and space plants adequately.
- Treatment: Remove and destroy affected plant parts. In severe cases, use a fungicide.
-
Basal Rot: Caused by overly wet soil, this fungal disease rots the base of the bulb.
- Prevention: Crucial to plant in well-drained soil. If you suspect basal rot, dig up the bulb, remove affected parts, dust with fungicide, and replant in a better-drained location.
No Blooms?
If your lilies aren’t blooming, several factors could be at play:
- Too Much Shade: Lilies need plenty of sun. If they’re in too much shade, they’ll produce foliage but few flowers.
- Immature Bulbs: Newly planted small bulbs might need a season to establish before blooming robustly.
- Overcrowding: If bulbs have naturalized heavily, they might be too crowded and need dividing.
- Nutrient Imbalance: Too much nitrogen can lead to lush foliage but no flowers. Ensure a balanced fertilizer.
- Damaged Bulbs: Pests, disease, or physical damage can prevent blooming.
Sustainable and Eco-Friendly Lily Gardening
Gardening is all about working with nature, not against it. When you decide can lilies be planted outside, you’re also choosing a path towards a more sustainable and eco-friendly garden. Incorporating sustainable practices not only benefits the environment but often leads to healthier, more resilient plants.
Here are some ways to make your lily garden greener:
- Compost Power: Instead of synthetic fertilizers, enrich your soil with homemade compost. It improves soil structure, provides slow-release nutrients, and reduces waste. This is a cornerstone of eco-friendly can lilies be planted outside.
-
Water Conservation:
- Use mulch to reduce evaporation and keep soil moisture consistent.
- Consider drip irrigation or soaker hoses to deliver water directly to the roots, minimizing waste.
- Collect rainwater for irrigation whenever possible.
-
Natural Pest Control:
- Encourage beneficial insects like ladybugs and lacewings by planting diverse flowers.
- Use organic pest control methods like insecticidal soaps or neem oil as a last resort.
- Practice companion planting: some plants can deter pests naturally. For example, garlic or chives planted nearby might deter some lily pests.
- Choose Native or Adapted Varieties: While most garden lilies are hybrids, selecting varieties known to thrive in your USDA hardiness zone minimizes the need for extensive intervention.
- Avoid Peat Moss: If possible, choose peat-free potting mixes or soil amendments. Peat harvesting has environmental concerns; alternatives like coir or compost are more sustainable.
- Support Biodiversity: By attracting pollinators, your lily patch contributes to local biodiversity, creating a healthier ecosystem in your own backyard.
Frequently Asked Questions About Planting Lilies Outside
Let’s tackle some of the most common questions gardeners have when considering how and if can lilies be planted outside.
Can lilies be planted outside in pots?
Absolutely! Many lily varieties do wonderfully in containers, especially if you have limited garden space or want to move them for display. Choose a pot at least 10-12 inches in diameter and depth with good drainage. Plant bulbs a bit closer together than in the ground for a fuller look. Ensure they still get plenty of sun and are protected in winter in colder zones (e.g., by moving pots to an unheated garage).
How deep should lily bulbs be planted?
A good rule of thumb is to plant lily bulbs about 6-8 inches deep, or roughly two to three times the height of the bulb itself. This depth helps protect the bulb from temperature extremes and provides support for the stem. Some smaller species might go a bit shallower, but for most garden lilies, this depth is ideal.
Do lilies need full sun?
Most lilies prefer at least 6-8 hours of direct sunlight per day to produce the best blooms. However, they appreciate having their roots kept cool, so a location where the tops get sun but the base is shaded by low-growing perennials or groundcover is ideal. Some varieties, like Martagon lilies, can tolerate partial shade, especially in hot climates where afternoon sun might be too intense.
When do outdoor lilies bloom?
The blooming period for outdoor lilies varies greatly by type. Asiatic lilies are typically the first to bloom, starting in early to mid-summer. Trumpet and Aurelian hybrids follow in mid-summer, with Oriental lilies bringing up the rear in mid to late summer, often extending the season into early fall. By planting a mix of varieties, you can enjoy lily blooms for months!
How long do lilies last outside?
With proper care and suitable growing conditions, many hardy lily varieties are perennial and can live for many years, even decades, in your garden. They will naturalize and multiply over time, forming larger clumps of bulbs. While individual flowers last about 1-2 weeks, the plant itself, and its ability to produce new blooms each year, can be incredibly long-lived.
