How to Grow and Care Lilium Columbianum

Columbia lily (Lilium columbianum) is a lily native to western North America with a habitat extending from Canada to northern California. In the wild, you will encounter him in open forests. If cultivating, plant in moist, well-drained soil in late fall.

Protection, breaking love spells. It is used to symbolize danger, caution, and deadly beauty. Yellow: I walk in the air. Happiness White: sweetness, purity Tiger: wealth, pride Orange: wealth Calla: day of beauty

Basic Care Guide
Columbia lily likes moisture, but is not resistant to standing water. A strict water regime is required during the seedling period. Water less frequently after seedlings emerge, except during dry periods. Water the plants after topdressing (soil improvement). Facilitate soil drainage in the rain system.

Fertilize seedlings during early growth to provide adequate nutrients for stem growth. Later change the soil based on plant and soil conditions. Apply compound fertilizer before sowing; Manure can be added.
Change the soil twice during the growing season. When the seedling is about 10 cm tall, give complete fertilizer. During rapid growth and tuber enlargement, compound fertilizer should be applied again.

Columbia lilies prefer filtered sunlight. If it is too strong, it can affect the quality of the flowers and the whole plant. Most lilies need between four and six hours (or more) of sunlight. With more sunlight, the plant can produce more food and produce more leaves and flowers.
If your Columbia lily is planted in an area that receives a lot of strong, direct sunlight, about 30% of the sunlight should be blocked. When planted in a garden, it should be planted at the edges of shrubs or next to fences.

When buds emerge, the terminal bud (main bud) should be removed to reduce nutrient consumption, transfer nutrients to the bulb, and help the bulb expand. At the same time, remove the buds that grow where the shoot grows out of the main shoot (the leaf axil).
Pinch off the buds after the dew has dried on a sunny morning. Damaged, dead or too long branches should be removed to look nicer and keep the lily healthy. After flowering, cut back wilted flowers to facilitate the blooming of other buds.

Advanced Care Guide
The optimal temperature during the growing season is 16 – 25 ℃. When temperatures exceed 28°C, the plant becomes smaller, there are fewer flower buds and blind (non-productive) buds may appear. When rooting, the soil temperature should be kept at 12 – 15 ℃.
When temperatures drop below 13°C at night, the leaves can turn yellow and fall off. Below 8℃ the plant will stop growing. Columbia lily is not frost hardy, and bulbs should be harvested and stored in the fall.
Water continuously in the high summer temperatures to cool the plant and soil temperature. Lilies should be watered immediately after planting and every two to three days thereafter. They need about an inch of water each week.
Stop watering 10 days before harvesting the bulbs, as the Colombia lily is not resistant to standing water. High soil moisture can lead to the death of seedlings. Therefore, pay attention to drainage during the rainy season.

Plant the Columbia lily in loose, fertile, slightly acidic soil rich in organic matter. Constantly growing lilies in the same spot can seriously affect the quality of the flowers, so plant them in well-drained, thick, sandy loam where Liliaceae plants have not previously been planted.

Columbia lilies are widely available at local flower shops or from many online retailers. Choose a plump bulb with sturdy roots, free from pests and diseases, and a flat, rounded top. Soak the bulb in fungicide and dry before planting.
The optimal planting time is the end of autumn, but the Colombia lily can also be planted in spring. If planted in the fall, the plant will root first. When planting in spring, the buds germinate first. Plant as early as possible after the spring thaw to avoid damage from cold temperatures.
When planting, position the bulb with the tip of the bud up and the roots down. Two or three times as thickcover with soil like the onion height. Water thoroughly to wet it, but not so much that water collects. Support weak stems with stakes as they grow.
