You can get tiger lilies to rebloom by understanding their natural growth cycle and giving them the right care at the right time.
Tiger lilies are hardy, vibrant perennials that can produce a second flush of blooms, but getting tiger lilies to rebloom isn’t just about luck.
It’s about deadheading spent flowers, feeding the bulbs, and knowing when to cut back the foliage so the plant stores energy for another round.
If you’ve been struggling with getting tiger lilies to rebloom after that first glorious show, don’t worry, you’re in the right place.
In this post, we’ll break down exactly how to encourage tiger lilies to rebloom, including the best practices for deadheading, fertilizing, and even tricking them into a second bloom.
Let’s dig into the secrets of making tiger lilies rebloom so you can enjoy those striking orange speckled petals twice in one season.
Why Tiger Lilies Rebloom and What Stops Them
First, it helps to know why tiger lilies rebloom in the first place, and what usually prevents it.
Tiger lilies (Lilium lancifolium) are genetically programmed to bloom in early to mid-summer, but they can rebloom if conditions mimic their native woodland edges.
The main reason tiger lilies fail to rebloom is that the bulb runs out of energy after the first flowering.
When you remove the flower stalk too early, or let the seed pods form, the plant diverts energy into seed production instead of bulb storage.
So, to get tiger lilies to rebloom, you must focus on energy conservation and redirecting that energy back into the bulb.
Another common culprit is overcrowding, as tiger lilies multiply underground and compete for nutrients.
If your clump has grown too dense, you’ll see fewer blooms each year, not more.
And if you’ve been cutting back the green leaves right after flowering, you’re starving the bulb of the photosynthesis it needs to fuel a rebloom.
1. Deadheading Spent Blooms Is the First Step
Deadheading is the single most effective way to encourage tiger lilies to rebloom.
Once the petals drop and the flower fades, snip off the ovary at the base of the bloom, but leave the stem and leaves intact.
This prevents seed pod formation, which is a massive energy drain.
By removing the spent flower head, you signal the plant to focus on bulb growth rather than reproduction.
You can deadhead as each flower fades, working your way down the stalk over a week or two.
And don’t wait too long, because once the seed pod swells, the plant has already committed resources to it.
Do this consistently, and you’ll see a noticeable difference in how quickly your tiger lilies rebloom.
2. Feed the Bulb Right After Flowering
Right after the first bloom fades is the critical feeding window for getting tiger lilies to rebloom.
Apply a balanced fertilizer with a ratio like 5-10-10 or 10-10-10, focusing on phosphorus and potassium over nitrogen.
Nitrogen pushes leafy growth, but phosphorus supports root and bulb development, which is what you need for a second bloom.
Sprinkle the fertilizer around the base of the plant, about 4-6 inches away from the stem, and water it in well.
You can also work in a layer of compost or well-rotted manure to feed the soil microbes that help bulbs absorb nutrients.
Repeat this feeding once more in late summer if you’re hoping for an autumn rebloom.
Just avoid over-fertilizing, because too much can burn the bulb and actually reduce flowering.
3. Leave the Foliage Alone Until It Yellows
This is where most gardeners go wrong when trying to get tiger lilies to rebloom.
After the flowers are gone, the leaves are still working hard, photosynthesizing and sending sugars down to the bulb.
If you cut the stalk down to the ground, you stop that energy flow completely.
Instead, let the foliage remain upright and green for at least 6-8 weeks after blooming.
Only when the leaves naturally turn yellow and wither should you trim them back to soil level.
You can tidy up by removing the top third of the stem after deadheading, but never go below that.
This patience pays off because the bulb stores that energy and uses it to produce a second round of tiger lily rebloom.
Advanced Tricks to Force Tiger Lilies to Rebloom
If you’ve mastered the basics and still want an extra push, try these advanced techniques.
Tiger lilies rebloom more reliably when you simulate a mild “cooling” period or provide extra root space.
Here are three methods that growers swear by.
1. Divide Overcrowded Clumps in Early Spring
Overcrowding is a silent killer of rebloom potential.
When tiger lilies form a dense mat of bulbs, each one gets less water and fewer nutrients.
Dig up the clump in early spring, before new growth is more than a few inches tall.
Gently separate the bulbs, making sure each division has at least a few healthy roots attached.
Replant them 6-8 inches apart and at a depth of 4-6 inches.
This gives each bulb room to stretch and store energy, which directly encourages tiger lilies to rebloom.
Do this every 3-4 years, and you’ll keep the colony vigorous and blooming reliably.
2. Provide Consistent Moisture Without Waterlogging
Tiger lilies rebloom best when the soil stays evenly moist, but never soggy.
Too much water can rot the bulb, while too little stresses the plant and halts flower bud formation.
Mulch the soil surface with 2 inches of organic material like bark or shredded leaves.
This retains moisture, keeps roots cool in summer heat, and suppresses weeds that compete for water.
Water deeply once a week during dry spells, and aim the stream at the soil, not the leaves.
Consistent moisture in late summer is especially important because that’s when the bulb is setting buds for next year’s bloom.
3. Try a Light “Shock” by Removing the First Bud
Here’s a sneaky trick for getting tiger lilies to rebloom faster.
If you pinch off the very first bud that forms, the plant sends a signal that it hasn’t bloomed yet.
Instead of putting all its energy into that one flower, it produces more buds lower on the stem.
This can extend the blooming period and, in some cases, trigger a second wave after the first flush fades.
It’s a bit counterintuitive, but many lily enthusiasts use this to squeeze out more tiger lily rebloom.
Just be sure to do this only on healthy, well-established plants, not on stressed or newly planted bulbs.
And always pair this with deadheading and feeding for the best results.
So, How Do You Get Tiger Lilies to Rebloom?
You get tiger lilies to rebloom by managing their energy cycle with deadheading, feeding, and patient foliage care.
The process isn’t complicated, but it does require timing and consistency.
Start by deadheading every spent flower as soon as the petals fall.
Feed the bulbs with a low-nitrogen fertilizer right after the first bloom.
Leave the green leaves to gather sunlight for at least two months.
Divide overcrowded clumps every few years to keep bulbs healthy.
And if you’re adventurous, pinch off that first bud to encourage more branching and a second round.
With these steps, you’ll not only get tiger lilies to rebloom once, but you might even enjoy a lovely encore in late summer or early fall.
So go ahead, give your tiger lilies the care they crave, and watch those fiery orange blooms light up your garden twice this season.
Happy planting, and here’s to a garden full of reblooming tiger lilies.
