Lilium , commonly known as lilies, are prized for their vibrant colors and beautiful blooms. However, once the flowers have faded, it’s important to properly preserve the bulbs so they can be reed and continue to add beauty to your garden year after year. Preserving Lilium bulbs after flowering involves a few simple steps that will ensure the bulbs remain healthy and ready for planting in the next season.
1. Timing is key: Once the flowers have wilted and the plant begins to turn yellow, it is time to remove the spent flowers and prepare the bulbs for preservation. Cut the flower stems about 1-2 inches above the bulb, leaving green foliage intact.
2. Let the foliage die naturally: After the flowers have been removed, allow the foliage to wither and turn yellow. This process allows the bulbs to absorb essential nutrients for next year’s growth. Avoid cutting or removing the foliage prematurely, as this can weaken the bulbs and hinder their ability to energy.
3. Digging up the bulbs: Once the foliage has completely died down, it’s time to dig up the bulbs. Use a spade or garden fork to carefully lift the bulbs from the ground, taking care not to damage them. Gently remove any excess soil, but avoid washing the bulbs as moisture can lead to rot.
4. Assessing the bulbs: Inspect each bulb for any signs of damage or disease. Discard any bulbs that appear soft, blackened, or otherwise unhealthy. Only use firm and healthy bulbs for preservation.
5. Cleaning the bulbs: Remove any remaining foliage or roots from the bulbs, but avoid removing the basal plate, which is the area where the roots attach. Allow the bulbs to dry naturally for a few days in a cool, well-ventilated area.
6. Preparing for storage: Before storing the bulbs, it’s important to prepare them for preservation. Dust the bulbs with a fungicide powder to protect against rot and other diseases during storage. Place the bulbs in a paper bag or mesh bag, ensuring there is proper ventilation.
7. Storage conditions: Store the bulbs in a cool, dry, and dark location. A temperature range of 45-55°F (7-13°C) is considered ideal for preserving Lilium bulbs. Basements or crawl spaces make great storage areas. Make sure the area is well-ventilated to prevent the buildup of moisture.
8. Regular inspection: Check the bulbs periodically during storage to ensure they are remaining firm and healthy. Remove any bulbs showing signs of rot or decay immediately to prevent the spread to other bulbs.
9. Preparing for planting: A few weeks before the planting season, take the bulbs out of storage and inspect them again. Remove any dry or dead scales on the bulbs. Soak the bulbs in a fungicide solution for about an hour to protect them from soil-borne diseases.
10. Planting the preserved bulbs: Once the bulbs have been prepared, they are ready for planting. Choose a sunny and well-drained location in your garden. Dig a hole deep enough to accommodate the size of the bulb and place it in the hole, ensuring the basal plate is facing down. Cover the bulb with soil, lightly press it down, and water thoroughly.
By following these simple steps, you can successfully preserve your Lilium bulbs after flowering, ensuring they will continue to bring joy and beauty to your garden for years to come. With proper care and attention, you can enjoy the vibrant blooms of lilies season after season.
