Selecting the Right Lily Varieties

With over 100 species and countless hybrid varieties, lilies offer an incredible diversity of colors, shapes and sizes. Here are some popular categories to consider:

Asiatic Lilies

Known for their vibrant colors and upward-facing flowers, Asiatic lilies are hardy, early bloomers that thrive in full sun.

Oriental Lilies

These lilies are prized for their large, fragrant blooms and come in a range of colors from white to pink and red.

Trumpet Lilies

As the name suggests, these lilies feature elongated, trumpet-shaped flowers and are often highly fragrant.

Tiger Lilies

With their distinctive orange color and speckled petals, tiger lilies add a bold and exotic touch to any garden.

Planting and Growing Conditions

To ensure your lilies thrive, it’s essential to provide them with the right growing conditions and planting techniques:

Timing

Plant lily bulbs in the fall or early spring, depending on your climate and the variety you choose.

Location

Most lilies prefer full sun to partial shade and well-draining soil. Avoid planting them in areas with standing water or heavy clay soil.

Soil Preparation

Before planting, amend the soil with organic matter like compost or well-rotted manure to improve fertility and drainage.

Planting Depth

As a general rule, plant lily bulbs three times as deep as their height. Space them according to the mature size of the variety.

Watering and Fertilizing

Proper watering and fertilization are crucial for the healthy growth and abundant blooms of your lily plants:

Watering

Lilies require consistent moisture but should never sit in waterlogged soil. Water deeply and allow the soil to dry out slightly between waterings.

Fertilizing

Apply a balanced, slow-release fertilizer formulated for bulbs in early spring when growth emerges. Avoid over-fertilizing, as this can lead to weak stems and fewer blooms.

Staking and Support

Many lily varieties can grow quite tall, making them susceptible to damage from wind and heavy rain. To prevent this, provide support using stakes or grow through plant supports:

Staking

Insert sturdy stakes near the base of the lily plant and gently tie the stems using soft plant ties as they grow taller.

Grow-Through Supports

Place a grow-through support over the lily plant in early spring, allowing the stems to grow up through the openings for natural-looking support.

Pest and Disease Management

While lilies are generally hardy plants, they can be susceptible to certain pests and diseases. Here are some common issues to watch out for:

Lily Beetle

These bright red beetles and their larvae can quickly defoliate lily plants. Regularly inspect your plants and remove any beetles or larvae by hand.

Aphids

These small, sap-sucking insects can cause distorted growth and weaken plants. Control them with insecticidal soap or by introducing beneficial insects like ladybugs.

Botrytis Blight

This fungal disease appears as gray mold on leaves and flowers. Ensure proper air circulation, remove infected parts, and apply a fungicide if necessary.

Deadheading and Propagation

To keep your lilies looking their best and encourage healthy growth, practice regular deadheading and consider propagating new plants:

Deadheading

Remove spent flowers by snipping them off just below the bloom, taking care not to remove the leaves, as they are essential for photosynthesis.

Propagation

Lilies can be propagated by dividing mature clumps or by planting bulbils (small bulbs that form on the stem). Divide clumps in the fall or early spring, ensuring each division has a healthy bulb and foliage.

Winter Care

In colder climates, lilies may require some extra protection during the winter months:

Mulching

After the foliage has died back in the fall, apply a 2-4 inch layer of organic mulch, like straw or leaves, over the bulbs to insulate them from extreme cold.

Lifting and Storing

In areas with severe winters, consider lifting the bulbs in the fall and storing them in a cool, dry place until spring planting.

Companion Planting

Lilies can be beautifully incorporated into mixed borders and companion planted with other perennials and annuals:

Perennial Companions

Pair lilies with perennials like peonies, daylilies, and coneflowers for a stunning and long-lasting display.

Annual Companions

Surround lilies with annuals like cosmos, zinnias, and marigolds to add color and fill in gaps throughout the growing season.

Growing lilies is a truly enchanting and rewarding experience for gardeners of all skill levels.
