• LA Hybrids

 A cross between Longiflorum and Asiatic lilies, LA hybrids are known for their large, showy flowers and robust growth. They are easy to propagate and make an excellent choice for gardeners looking to add bold colors to their landscape.

• OT Hybrids

 These hybrids, also known as Orienpet lilies, are a combination of Oriental and Trumpet lilies. They produce huge, fragrant blooms and have a strong growth habit, making them a favorite for propagation and garden display.

• LO Hybrids

 Combining Longiflorum and Oriental lilies, LO hybrids offer the best of both worlds with their fragrant, long-lasting flowers and sturdy stems. They are suitable for propagation and thrive in well-drained soil with plenty of sunlight.

Methods of Lilies Propagation

Propagating lilies can be accomplished through several effective methods. Each technique has its unique steps and benefits, providing gardeners with various ways to increase their lily population and enjoy these beautiful flowers.

Bulb Division

Dividing lily bulbs is a straightforward and reliable method for propagation, especially for established clumps of lilies that have grown crowded. This technique involves separating offsets, or baby bulbs, from the parent bulb and planting lily bulbs individually. The best time to divide lily bulbs is in the fall, after the foliage has died back but before the ground freezes. This timing allows the new divisions to establish roots before winter.

Carefully dig around the clump of lilies with a garden fork or spade, taking care not to damage the bulbs. Lift the clump out of the ground and gently shake off excess soil. Identify the offsets attached to the parent bulb. These smaller bulbs should be carefully separated from the parent bulb by gently twisting or cutting them away, ensuring each offset has its roots intact. Check the bulbs for any signs of disease or damage. Discard any unhealthy bulbs. Dust the healthy bulbs with a fungicide to prevent fungal infections. Prepare the new planting site with well-drained soil enriched with compost. Plant the parent bulb and offsets at a depth of about 6 inches, spacing them 12 to 18 inches apart. Water the newly planted bulbs thoroughly and apply a layer of mulch to protect them over winter.

Seed Propagation

Growing lilies from seeds is a rewarding but more time-intensive method compared to bulb division. This technique allows for the creation of new hybrids and the preservation of unique genetic traits. Here’s how to propagate lilies from seeds:

• Collecting Seeds: Allow lily seed pods to mature on the plant. Once the pods turn brown and start to split open, collect the seeds. Clean the seeds thoroughly to remove any debris.
• Stratifying Seeds (if needed): Some lily seeds require a period of cold stratification to break dormancy. Place the seeds in a moist medium such as peat moss or vermiculite, and store them in a refrigerator for 6 to 8 weeks.
• Sowing the Seeds: Fill seed trays or pots with a well-draining seed-starting mix. Sow the seeds on the surface and cover them lightly with a thin layer of the mix or sand. Water the seeds gently to avoid displacing them.
• Providing Optimal Conditions: Place the seed trays in a warm, bright location with indirect sunlight. Maintain consistent moisture by misting the soil regularly. Germination can take several weeks to months, depending on the lily variety.
• Transplanting Seedlings: Once the seedlings have developed a few sets of true leaves, they can be transplanted into individual pots or directly into the garden. Harden off the seedlings by gradually exposing them to outdoor conditions before planting them in their permanent location. It may take several years for seed-grown lilies to mature and produce flowers, so patience is essential.

By mastering these propagation techniques, you can successfully expand your collection of lilies and enjoy their stunning blooms and delightful fragrance year after year. Each method has its own charm and challenges, offering different ways to grow these beautiful plants and enhance your garden.

Scaling

Scaling is a method used to propagate lilies by removing and planting the outer scales of a lily bulb. Choose a healthy, disease-free lily bulb for scaling. Gently remove several outer scales from the bulb, being careful not to damage the basal plate where the scales are attached. Dust the scales with a fungicide to prevent rot and fungal infections. Place the treated scales in a plastic bag with a moist medium like vermiculite or peat moss. Seal the bag and store it in a warm, dark place for several weeks. Check regularly for the development of bulbils (tiny bulbs) at the base of the scales. Once bulbils have formed, plant them in pots or directly in the garden, ensuring they have well-drained soil and adequate water. Scaling is an effective method for multiplying lily plants, especially for rare or valuable varieties.

Care Tips After Propagation

Once you’ve successfully propagated your lilies, proper care is essential to ensure they thrive in their new environment. From transplanting to ongoing maintenance, following these care tips will help your lilies grow healthy and strong, rewarding you with beautiful blooms.

Transplanting

Transplanting propagated lilies into the garden requires careful handling to ensure the young plants establish well and continue to grow vigorously. Transplant your propagated lilies in the early spring or fall. These seasons provide moderate temperatures and adequate moisture, helping the lilies establish roots without the stress of extreme weather conditions. Select a location with well-drained soil and plenty of sunlight. Lilies thrive in areas that receive at least six hours of direct sunlight per day. Amend the soil with organic matter, such as compost, to improve drainage and fertility.

Dig holes that are about 6 inches deep and wide enough to accommodate the bulbs or seedlings. Place each bulb or seedling in the hole, ensuring the roots are spread out. Cover with soil and gently firm it around the plant. Space the lilies 12 to 18 inches apart to allow for adequate air circulation and room for growth. Water the newly transplanted lilies thoroughly to settle the soil around the roots. Keep the soil consistently moist but not waterlogged during the establishment period.

Maintenance

Proper maintenance is crucial to support the growth and blooming of your propagated lilies. Follow these tips to ensure your lilies remain healthy and vibrant:

1. Mulching: Apply a layer of mulch around the base of the lilies to help retain soil moisture, suppress weeds, and regulate soil temperature. Organic mulches such as straw, shredded bark, or compost work well.
2. Fertilizing: Feed your lilies with a balanced, slow-release fertilizer in the spring as new growth emerges. Avoid high-nitrogen fertilizers, which can promote excessive foliage growth at the expense of blooms. A second application of fertilizer can be made in mid-summer to support blooming and bulb development.
3. Staking: Tall lily varieties may require staking to prevent the stems from bending or breaking under the weight of the flowers. Install stakes early in the growing season and tie the stems loosely to the stakes with soft ties or twine.
4. Deadheading: Remove spent flowers promptly to encourage the plant to focus its energy on bulb development rather than seed production. Cut the flower stalks down to the base once all the blooms have faded.
5. Pest and Disease Control: Monitor your lilies regularly for signs of pests or diseases. Common pests include aphids, lily beetles, and slugs, which can be controlled with insecticidal soap or hand-picking. Fungal diseases like botrytis blight can be managed by ensuring good air circulation, avoiding overhead watering, and applying fungicides if necessary.
6. Winter Protection: In colder climates, provide winter protection for your lilies by applying a thick layer of mulch after the ground freezes. This helps insulate the bulbs and prevent frost damage. In spring, remove the mulch gradually as temperatures rise and new growth appears.

Troubleshooting Common Issues

Even with the best care, propagated lilies can sometimes face challenges. Understanding how to manage pests, diseases, and environmental stress can help ensure your lilies remain healthy and vibrant.

Environmental Stress

Environmental stress can significantly impact the health and growth of propagated lilies. Here are tips for addressing common stress factors:

• Heat Stress

Lilies may wilt or show scorched leaves in extreme heat. Provide shade during the hottest part of the day and ensure consistent watering.

Cold Stress: Protect lilies from frost by applying a thick layer of mulch in late fall. In colder climates, consider using cloches or frost blankets during unexpected cold snaps.

• Water Stress

Overwatering: Ensure proper soil drainage to prevent waterlogged conditions that can lead to root rot. Water lilies deeply but infrequently, allowing the soil to dry out slightly between waterings.

Underwatering: During dry periods, water lilies regularly to maintain consistent soil moisture. Mulching can help retain soil moisture and reduce evaporation.

• Nutrient Deficiencies

Yellowing Leaves: This can be a sign of nitrogen deficiency. Apply a balanced, slow-release fertilizer in spring and mid-summer to ensure your lilies receive adequate nutrients.

Poor Flowering: A lack of phosphorus can result in poor blooming. Use a fertilizer high in phosphorus to promote flower development.

• Soil Problems

Compacted Soil: Compacted soil can hinder root growth and water penetration. Aerate the soil around your lilies and amend it with organic matter to improve its structure and drainage.

Incorrect pH: Lilies prefer slightly acidic to neutral soil (pH 6.0-7.0). Test the soil pH and amend it with lime or sulfur as needed to adjust the pH to the optimal range.
