If you’re looking to keep your lilies looking their best, pruning is a must. While it can seem like a daunting task, it’s actually quite simple and can make a big difference in the health and appearance of your plants. Here’s a quick guide to help you get started.
The first step is to identify the type of lily you have. Different types of lilies have different pruning needs, so it’s important to know what you’re dealing with before you start cutting. Once you’ve identified your lily, you can begin removing any dead or diseased stems. These stems can harbor pests and diseases, so it’s important to get rid of them as soon as possible. Next, you’ll want to remove any leaves that are yellowing or brown. These leaves are no longer providing any nutrients to the plant, and they can make your lily look unkempt. Finally, you can start shaping your lily by removing any stems that are too long or unruly. This will help create a more compact and attractive plant.
Pruning lilies is a simple task that can make a big difference in the health and appearance of your plants. By following these steps, you can keep your lilies looking their best all season long.
Understanding the Types of Lilies
Lilies belong to the Liliaceae family and are classified into various divisions based on their growth habits and flowering characteristics. Understanding these different types is crucial for proper pruning and care.
Asiatic Lilies
Asiatic lilies are the most common type of lilies, known for their vibrant colors and trumpet-shaped flowers. They typically bloom in mid to late summer and reach heights of 2-4 feet. Asiatic lilies are easy to grow and relatively low maintenance, making them a popular choice for gardeners.
Subdivisions of Asiatic Lilies
* Division 1: Single lilies with a single row of petals and visible stamens.
* Division 2: Double lilies with multiple rows of petals and hidden stamens.
* Division 3: Trumpet lilies with long, funnel-shaped flowers.
* Division 4: Curled lilies with recurved petals and ruffled edges.
* Division 5: Reflexed lilies with backward-facing petals.
* Division 6: Martagon lilies with pendant flowers and spotted foliage.
| Division | Flower Shape | Petal Arrangement |
|---|---|---|
| 1 | Single | Single row |
| 2 | Double | Multiple rows |
| 3 | Trumpet | Funnel-shaped |
| 4 | Curled | Recurved, ruffled |
| 5 | Reflexed | Backward-facing |
| 6 | Martagon | Pendant, spotted foliage |
Timing is Key: When to Prune Lilies
Determine the Lily Type
Lilies fall into two main categories:
- Asiatic lilies: Prune in late fall or early spring after foliage has turned brown and died back.
- Oriental and trumpet lilies: Prune in early spring before new growth appears.
Remove Old Blooms and Stems
Pruning lilies after blooming helps prevent seed formation, which can weaken the plant.
To remove spent blooms:
- Use sharp pruning shears to cut the flower stem just above the first set of healthy leaves.
- Remove any remaining buds or seed pods that may have formed.
For Oriental and trumpet lilies, you can also remove any remaining foliage that has turned brown or yellow.
Table: Pruning Guidelines for Different Lily Types
| Lily Type | Pruning Time | Parts to Remove |
|---|---|---|
| Asiatic | Late fall or early spring | Spent blooms and stems |
| Oriental and trumpet | Early spring (before new growth) | Spent blooms, stems, and brown/yellow foliage |
Tools of the Trade: Must-Haves for Pruning
### Hand Pruners: Precision Pruning for Clean Cuts
Hand pruners are essential for precise pruning and maintaining healthy lily plants. Opt for bypass pruners, which use a scissor-like action to make clean cuts that promote rapid healing. Look for pruners with sharp, durable blades made of high-carbon steel or forged aluminum. Ergonomic handles provide comfort and control during extended use.
### Lopping Shears: Extended Reach for Taller Lilies
Lopping shears are longer-handled pruning tools designed to tackle thicker stems and reach taller lilies. These shears feature longer blades (usually 12-24 inches) and extendable handles for greater reach. Choose a pair with sharp, bypass blades and lightweight, corrosion-resistant materials.
### Hedge Trimmers: Efficient Pruning for Bushier Lilies
Hedge trimmers provide a quick and efficient way to trim back bushy lilies. Electric or gas-powered hedge trimmers offer varied cutting capacities and blade lengths. Look for trimmers with a double-sided reciprocating blade for a clean, precise cut. Consider weight, balance, and ergonomic handles to ensure comfortable use.
### Saw: Pruning Thick or Awkward Stems
A saw is essential for pruning thick stems or branches that cannot be cut with hand pruners or lopping shears. Choose a saw with sharp, serrated teeth designed for pruning, such as a Japanese pruning saw or a reciprocating saw. Ensure the saw is well-maintained and sharp to avoid tearing or damaging lily stems.

Pruning Asiatic Hybrids for Optimal Bloom
Asiatic hybrids are a popular choice for gardeners due to their vibrant blooms and low maintenance. To ensure optimal bloom production, it’s essential to prune them properly.
1. Time for Pruning
The best time to prune Asiatic lilies is after flowering has finished, typically in late summer or early fall. This allows the plant to store energy in its bulbs for the next growing season.
2. Removing Stems
Cut back the flower stems to about 6 inches above the ground. This helps prevent the plant from putting energy into seed production and promotes new growth in the following season.
3. Removing Foliage
Do not remove the foliage until it has completely turned yellow and withered. The leaves play a crucial role in photosynthesis, helping the plant store nutrients for winter.
4. Removing Diseased or Damaged Foliage
Inspect the plant carefully for any diseased or damaged foliage. Remove these leaves as soon as possible to prevent the spread of disease. Diseased foliage should be disposed of away from the garden to minimize contamination.
| Type of Damage or Disease | Symptoms | Control |
|---|---|---|
| Botrytis | Brown or gray, fuzzy spots on leaves and flowers | Remove infected plant parts and apply fungicide |
| Fusarium wilt | Yellowing and wilting of leaves, followed by collapse of the plant | Destroy infected plants and avoid planting lilies in the same location for several years |
| Lily virus | Yellow or white streaking on leaves | Remove infected plants and dispose of them away from the garden |
Handling Oriental Hybrids with Care
Oriental Hybrids are among the most popular and prized lilies for their large, showy flowers and heady fragrance. However, they also have a reputation for being somewhat tender and susceptible to certain diseases, especially botrytis. Therefore, it is important to handle them with extra care when pruning.
Here are some tips for pruning Oriental Hybrids:
- Wait until the flowers have completely faded and the petals have dropped before pruning.
- Cut the flower stalk back to about 6 inches above the ground.
- Avoid cutting into the healthy stem tissue.
- Remove any dead or diseased leaves from the plant.
- Be sure to disinfect your pruning shears before and after pruning to prevent the spread of disease.
By following these tips, you can help your Oriental Hybrid lilies stay healthy and bloom beautifully for years to come.
| Pruning Time for Oriental Hybrids | Recommended Actions |

Shaping Tree Lilies for Architectural Interest
Tree lilies are known for their elegant, architectural form, which can be enhanced even further with strategic pruning. Here’s how you can shape your tree lilies to create a captivating focal point in your garden:
Pruning Techniques
Tree lilies can be pruned at any time of the year, but it’s best to wait until after flowering to avoid compromising bloom production. Use clean, sharp pruning shears or a saw for larger branches.
Removing Suckers
Tree lilies tend to produce suckers, which are shoots that grow from the base of the main plant. These suckers can compete for nutrients and weaken the main stem, so they should be removed as soon as they appear. Cut them off close to the base using sharp pruning shears.
Trimming Leggy Stems
Leggy stems, which are weak and have few leaves, can detract from the overall appearance of the tree lily. Trim these stems back by about one-third to promote bushier growth.
Creating a Central Leader
A central leader is the main trunk of the tree lily. To encourage a strong, upright leader, remove any lateral branches that are competing with it. This will help to create a balanced, symmetrical shape.
Shaping the Canopy
The canopy of the tree lily is the upper portion of the plant that consists of leaves and branches. Prune the canopy to control its size and shape. Thin out excess branches to encourage air circulation and prevent disease. Remove any dead or diseased branches as well.
Lifting the Canopy
If you desire a tree lily with a higher canopy, you can remove the lower branches. This will expose the trunk and create a more dramatic visual effect. However, only prune a few branches at a time to avoid stressing the plant.
Enhancing Branch Structure
To enhance the branch structure of the tree lily, you can use a technique called “heading back.” This involves cutting back branches to an outward-facing bud or lateral branch. This encourages the growth of new branches and helps to create a more dense, compact canopy.
Post-Pruning Care
After pruning your tree lily, it’s important to provide proper care. Water the plant deeply to help it recover from the pruning process. Fertilize the plant with a balanced fertilizer to support its growth and health.
Maintaining Asiatic Lilies for Compact Growth
Remove Spent Blooms
As soon as the flowers have faded and wilted, promptly remove the spent blooms by cutting the stem just below the flower head. This prevents the plant from putting energy into seed production and encourages it to focus on foliage growth.
Deadhead Regularly
Continue to deadhead any remaining buds or flowers that may still appear. This forces the plant to redirect its resources towards vegetative growth, resulting in a bushier and more compact form.
Cut Back Stems After Flowering
Once the blooming period is completely finished, cut back the stems to about 6-8 inches (15-20 cm) above the base of the plant. This helps promote new, compact growth and prevents the plant from becoming leggy.
Remove Yellowed or Diseased Leaves
As the leaves turn yellow or brown, remove them promptly to prevent disease from spreading. This also improves the appearance of the plant and encourages healthy growth.
Fertilize Regularly
Feed the plants every 3-4 weeks during the growing season with a balanced fertilizer. This provides essential nutrients for optimal growth and flowering.
Water Deeply
Water the plants deeply and infrequently, allowing the soil to dry out slightly between waterings. This encourages strong root development and prevents rot.
Provide Support
If the stems become too tall or top-heavy, provide support with stakes or a trellis. This prevents the plants from flopping over and ensures proper growth.
Mulch Around the Base
Spread a layer of mulch around the base of the plants to retain moisture, suppress weeds, and regulate soil temperature.
Protect from Pests and Diseases
Monitor the plants regularly for pests and diseases. Treat any infestations promptly to minimize damage and maintain plant health.
| Pest/Disease | Symptoms | Treatment |
|---|---|---|
| Aphids | Small, soft-bodied insects that suck sap | Insecticidal soap or neem oil |
| Botrytis blight | Grayish mold on leaves and stems | Remove infected parts and improve air circulation |
| Fusarium wilt | Yellowing leaves and stunted growth | No cure; discard infected plants |
When to Prune Lilies
The best time to prune lilies varies by species. Oriental, Asiatic and Trumpet lilies are best pruned after flowering (deadheading), while removing only the flower head. Once the plant begins to yellow and die back in the fall, cut the stem back to about 6 inches above the ground. Tiger lilies and many Candidum varieties should be pruned in the late fall or early spring once all the foliage has turned brown and died back.
Deadheading
Deadheading is the removal of spent flowers. This prevents the plant from putting energy into seed production and encourages more blooms. To deadhead a lily, simply remove the flower head from the stem, pinching it off with your fingers or cutting it off with sharp shears.
Fall Pruning
Fall pruning is done to remove the dead foliage and stems from the plant. This helps to prevent the spread of disease and pests, and it also makes the plant look neater. To fall prune a lily, cut the stems back to about 6 inches above the ground.
Spring Pruning
Spring pruning is done to remove any remaining dead or damaged foliage from the plant. It also helps to promote new growth. To spring prune a lily, cut the stems back to about 2 inches above the ground.
Winterizing Lilies through Proper Pruning
