Lifting and dividing lilies is best done in the fall, after their foliage has naturally yellowed and died back. If you have ever wondered how to transplant lillies without damaging the bulbs, this guide will walk you through every step. Lilies are hardy perennials that respond well to being moved, but timing and technique matter a lot. In this article, you will learn the exact process for transplanting lilies successfully, whether you are moving them to a new bed or dividing overcrowded clumps.
Transplanting lilies is not complicated, but it does require a gentle touch. The bulbs are fleshy and can bruise easily. With the right approach, you can relocate your lilies without losing blooms for the next season. Let us start with why you might need to transplant them in the first place.
Why Transplant Lilies
Lilies grow from bulbs that multiply underground over time. After a few years, a single bulb can become a cluster of bulbs, all competing for space and nutrients. This crowding leads to smaller flowers and weaker stems. Transplanting gives each bulb room to grow.
Another reason is changing your garden layout. You might want to move lilies to a sunnier spot or a different color scheme. Sometimes, lilies simply stop blooming well in their current location. Moving them can revitalize the plants.
Transplanting also helps control diseases. If you notice rot or fungal issues, lifting and dividing healthy bulbs can save your collection. Always discard any bulbs that are mushy or discolored.
When To Transplant Lilies
The best time for transplanting is autumn, after the foliage has died back. This is when the bulbs are dormant and least stressed. In most climates, this means September to November. You can also transplant in early spring, just as new shoots appear, but fall is safer.
Transplanting during active growth is risky. The bulbs are busy storing energy for next year. Disturbing them then can reduce flowering for a season or two. If you must move a lily in summer, do it on a cool, cloudy day and water well afterward.
Wait until the stems are completely brown and dry. This signals that the bulb has finished storing nutrients. Cutting the stems too early weakens the bulb. Let nature take its course.
Tools And Materials Needed
Before you start, gather a few basic tools. You will need a garden fork or spade, a bucket or tarp, and sharp pruners. Have some compost or well-rotted manure ready for the new planting hole. A measuring tape or ruler helps with spacing.
- Garden fork or spade
- Bucket or tarp for holding bulbs
- Sharp pruners or scissors
- Compost or organic matter
- Gloves (optional but recommended)
- Watering can or hose
Having everything ready makes the job smoother. You do not want to leave bulbs exposed to air for long. They dry out quickly. Work efficiently and keep bulbs covered with damp soil or a cloth if you need to pause.
How To Transplant Lillies
Now we get to the main event. Follow these steps carefully to ensure your lilies thrive after moving. This process works for all types of lilies, including Asiatic, Oriental, and Trumpet varieties.
Step 1: Lift The Bulbs Gently
Start by loosening the soil around the lily clump. Insert your garden fork several inches away from the stems to avoid slicing bulbs. Pry upward gently. Do not yank on the stems, as they may break off from the bulbs.
Once the clump is loose, lift it out with your hands or the fork. Shake off excess soil so you can see the bulbs clearly. You will likely find a cluster of bulbs connected by roots. Some may be small offsets, others full-sized.
Work slowly. Lilies can have deep roots, especially if they have been in the ground for years. Dig a wide circle around the clump to capture all the roots. Damaged roots heal slowly and can invite rot.
Step 2: Separate The Bulbs
Lay the clump on a tarp or in a bucket. Gently pull apart the bulbs by hand. If they are tightly stuck, use your pruners to cut the connecting roots. Do not tear the bulbs apart forcefully.
Discard any bulbs that are soft, moldy, or have holes from pests. Healthy bulbs are firm and plump, with a papery outer skin. Small offsets can be replanted, but they may take a year or two to flower.
Trim the stems down to about 2 inches above the bulb. This reduces moisture loss and makes planting easier. Leave the roots intact as much as possible. Roots are the lifeline for water uptake.
Step 3: Prepare The New Site
Choose a location with well-draining soil and full sun to partial shade. Lilies prefer at least six hours of sunlight daily. Avoid spots where water pools after rain, as bulbs rot easily in wet soil.
Dig a hole about 6 to 8 inches deep. The depth should be roughly three times the height of the bulb. For large bulbs, this means deeper holes. Space holes 8 to 12 inches apart, depending on the variety.
Mix some compost into the removed soil. This adds nutrients and improves drainage. Do not add fresh manure, as it can burn the bulbs. Well-rotted compost is ideal.
Step 4: Plant The Bulbs
Place each bulb in the hole with the pointed end facing up. The roots should spread out naturally. Cover the bulb with soil, pressing gently to remove air pockets. Do not tamp down too hard, as compacted soil hinders root growth.
Water the bulbs thoroughly after planting. This settles the soil and provides moisture for root development. Keep the soil moist but not waterlogged through the fall. If your area gets regular rain, you may not need to water much.
Add a layer of mulch, about 2 inches thick, over the planting area. Mulch insulates the bulbs from winter cold and helps retain moisture. Use shredded bark, straw, or leaf mold.
Step 5: Care After Transplanting
After transplanting, lilies need minimal care until spring. Do not fertilize immediately, as the bulbs are dormant. Wait until new growth appears in spring, then apply a balanced fertilizer like 10-10-10.
Remove the mulch gradually in spring as the weather warms. This allows shoots to emerge easily. Keep an eye out for slugs and snails, which love tender new growth. Use organic controls if needed.
Water during dry spells, especially in the first growing season. Established lilies are somewhat drought tolerant, but new transplants need consistent moisture. Aim for about 1 inch of water per week.
Common Mistakes To Avoid
Transplanting lilies is straightforward, but a few errors can set you back. Here are the most common pitfalls and how to avoid them.
- Planting too shallow: Bulbs need depth to stay cool and stable. Shallow planting leads to weak stems and frost damage.
- Planting too deep: If bulbs are buried too far, they may rot or take forever to emerge. Stick to the three-times rule.
- Leaving bulbs exposed: Air dries out bulbs quickly. Keep them covered or replant promptly.
- Watering too much: Overwatering causes rot. Let the soil dry slightly between waterings.
- Ignoring spacing: Crowded bulbs compete for nutrients. Give them room to multiply.
Avoid these mistakes and your lilies will reward you with beautiful blooms. Patience is key, as transplanted lilies may skip a year of flowering while they settle in.
Transplanting Lilies In Containers
If you grow lilies in pots, transplanting is similar but with a few tweaks. Container-grown lilies need repotting every 2 to 3 years because the soil depletes and bulbs multiply.
Tip the pot over and slide out the root ball. Gently separate the bulbs as described earlier. Use fresh potting mix with good drainage. Add perlite or sand if needed.
Choose a pot that is at least 12 inches deep to accommodate the roots. Ensure the pot has drainage holes. Water after repotting and place in a sheltered spot for winter if you live in a cold climate.
Container lilies are more vulnerable to freezing than in-ground ones. Move pots to a garage or wrap them in bubble wrap for insulation. Do not let the soil freeze solid.
Dividing Overcrowded Lilies
Dividing is a specific type of transplanting for when bulbs are too crowded. You will notice smaller flowers, fewer blooms, or stems that flop over. This is a sign to divide.
Follow the same lifting and separating steps. You can replant the largest bulbs immediately and pot up the smaller ones to grow on. Discard any that look unhealthy.
Dividing every 3 to 4 years keeps your lily patch vigorous. It also gives you free plants to share with friends. Just be sure to label varieties if you have different types.
FAQ About Transplanting Lilies
Can I transplant lilies in spring?
Yes, but it is riskier. Transplant in early spring before growth starts. The bulbs may bloom later or skip a year. Fall is still the best time.
How deep should I plant lily bulbs?
Plant bulbs about 6 to 8 inches deep, or three times their height. Larger bulbs need deeper holes. This protects them from temperature swings.
Do lilies need full sun after transplanting?
Lilies thrive in full sun to partial shade. At least 6 hours of direct sun is ideal. Too much shade reduces flowering and makes stems leggy.
How long do transplanted lilies take to bloom?
Most lilies bloom the following summer after a fall transplant. Small offsets may take 1 to 2 years. Be patient and provide good care.
Can I transplant lilies while they are blooming?
It is not recommended. Moving blooming lilies shocks them and they may drop flowers. Wait until after blooming or in fall.
Final Tips For Success
Transplanting lilies is a rewarding garden task. With the right timing and technique, you can enjoy healthy plants for years. Remember to work gently, keep bulbs moist, and choose a good location.
After transplanting, mark the spot so you do not accidentally dig there later. Lilies take time to establish, but the wait is worth it. Their tall stems and vibrant flowers are a highlight of any garden.
If you have multiple varieties, keep them seperated to avoid mixing. Label each clump with the name and color. This helps with future planning and dividing.
One more thing: do not fertilize immediately after transplanting. Wait until spring when growth resumes. Too much nitrogen now can encourage soft growth that winter kills.
With these steps, you now know how to transplant lillies like a pro. Whether you are moving a single bulb or a whole bed, the process is the same. Take your time, and your lilies will thank you with abundant blooms.
