How to Grow and Care for the Spider Lily

Spider Lily Care

Here are the main care requirements for growing spider lilies:

• Plant them away from automatic garden irrigation systems to avoid accidental watering.
• Plant spider lily bulbs approximately 6 to 12 inches apart, and leave 14 inch of each bulb top (the pointed end) sticking out above the soil. Gently firm the soil around the bulb.
• Do not disturb them by digging in their area.
• Don’t water from midspring to midsummer, as they are dormant during this time.
• They don’t require pruning,
• Spider lilies are not prone to any serious pest or disease issues.

Light

Spider lilies flower best in full sun to partial shade. Choosing a location that receives at least five to six hours of direct sunlight on most days is best.

Soil

Well-draining soil is essential for spider lilies. The bulbs can rot in waterlogged soil. An organically rich sandy or loamy soil with a slightly acidic to slightly alkaline soil pH will do. Amending the soil annually with bark, compost, or mulch will help to boost its nutrient content and improve its drainage.

Water

When they’re actively growing, spider lilies have moderate water needs. The soil should be kept lightly moist but never soggy. Then, as soon as the foliage degrades in the springtime, cease watering until flowering begins again in the late summer or fall.

Temperature and Humidity

Spider lilies don’t tolerate cold temperatures well. Temperatures below freezing can damage or even kill the plants. Humidity typically isn’t an issue as long as soil moisture and drainage are sufficient.

Fertilizer

In the early spring, spider lilies benefit from an application of high-nitrogen fertilizer, such as an 8-2-4, to encourage blooming after their dormant period. In the autumn after flowering, spider lilies should be fed with a high-phosphorus fertilizer, such as a 3-5-4, to help them survive the winter cold.

Types of Spider Lily

Spider lilies are low-maintenance perennials that can add a pop of fall color to any garden. There are several varieties of spider lily, including:

• White spider lily (Lycoris albiflora): The blooms of this spider lily are a delicate white.
• Golden spider lily (Lycoris aurea): This species sports golden yellow flowers.
• Red spider lily (Lycoris radiata): This plant features bright red blooms.
• Electric blue spider lily (Lycoris sprengeri): This species has pink flowers with blue streaking.
• Resurrection lily (Lycoris squamigera): The leaves of this species grow in the spring, die back in the summer, and then are followed by the flowers.

Propagating Spider Lilies

Healthy spider lilies will multiply in clumps over the years. So the best way to propagate your plants is by division once they are at least a few years old. Plan to divide a clump right after it goes dormant in the early summer. Not only does dividing provide you with new plants you can locate elsewhere, but it also prevents clumps from becoming overcrowded and losing their vigor. Here’s how:

1. Water the bulbs to loosen the soil.
2. Gently dig up the bulbs.
3. Separate and replant the bulbs in suitable growing sites.

Potting and Repotting Spider Lilies

Spider lilies can be grown in containers, though the containers must be large to accommodate their expansive root system. Opt for a container that’s at least 12 inches wide and deep. It also should have ample drainage holes. Unglazed clay is an ideal material, as it will allow excess soil moisture to evaporate through its walls, helping to prevent the bulbs from rotting.

Avoid having to repot by using a large container from the start, as spider lilies don’t like to have their roots disturbed.

Overwintering

If you live in the coldest parts of the spider lily’s growing zones, you might want to add a layer of mulch around your plants for winter to help insulate the bulbs. Another option is to plant your bulbs in containers that you bring indoors to overwinter.

How to Get Spider Lilies to Bloom

Spider lilies should readily bloom if their growing conditions are met. A common problem that results in a lack of blooms is the bulb being planted too deep or facing the wrong way. That pointed tip must be slightly above the soil line for blooming to occur.

The naked flower stems will grow quickly, seemingly out of nowhere, in the late summer to early fall. It’s not essential to deadhead, or remove the spent blooms. But it can help to promote further flowering.

Bloom Months

Spider lilies bloom in the midsummer through to early fall (July to September).

How Long Does Spider Lily Bloom?

Spider lilies should bloom for a couple of weeks.

What Does Spider Lily’s Flowers Look and Smell Like?

Spider lilies get their name from the curved cluster of petals that resemble a spider. Petals can bloom into several different colors, including red, orange, yellow, peach, and pink. Their fragrance is soft and sweet, and not overpowering.

How to Encourage More Blooms

Keeping the soil moist before blooming and using a fertilizer that is high in potassium and phosphorous will help strengthen spider lilies after blooming and help them survive winter.

Caring for Spider Lily After it Blooms

Water moderately during the growing season and withhold water in the summer as the foliage begins to die. Remove foliage when it turns yellow and begins to wither.

Common Problems With Spider Lilies

Spider lilies have very few issues when their soil, moisture, and light needs are met. However, they are not immune to growing problems.

Leaves Turning Yellow

Usually, when you see your spider lily’s foliage turning yellow, it’s a sign that the bulb is heading into dormancy. This should occur in the springtime. If leaves are yellowing when the foliage should be actively growing, that might be a sign of overwatering. Make sure the soil is just slightly moist to the touch rather than waterlogged.
