Do you know that getting continuous daylily blooms is actually really simple?
Despite what gardening forums and gurus on the internet might have told you, repeat blooming can be achieved with minimal effort if you know what you’re doing and act strategically.
In today’s article, allow me to take you through a complete guide on encouraging repeat blooming in your daylily plants even in late summer. Let’s get after it!
How To Encourage Repeat Blooming In Daylilies – Even In Late Summer
1: Ensure adequate sunlight
Daylily is the type of perennial that thrives in plenty of sunlight. Adequate light will be necessary for it to grow optimally and produce foliage as well as vibrant flowers.
Planting in shade or even partial shade isn’t ideal for daylillies, and it’s very likely to lead to poor results.
2: Deadhead spent blooms regularly
Deadheading is the simple practice of removing spent flowers after the plant is done blooming.
Doing so often encourages a new flush of blooms almost immediately and ensures healthy, vigorous blooming next time around. In the case of daylillies, you want to snap off wilted flowers just below the ovary gently.
Another benefit of deadheading is maintaining a clean, tidy appearance in your daylily plants, which can make your garden look 2x more visually appealing.
You should also check out these perennials that bloom again if cut back mid-summer, daylilies aren’t the only ones that benefit from a well-timed trim.
3: Maintain consistent moisture
Consistent moisture is another factor that contributes to healthy daylily blooming. More often than not, people confuse consistent moisture with overwatering and flooding a plant when that’s really not what consistent moisture is.
You should generally be aiming to provide your daylilies with about an inch of water per week. Make sure, however, that none of the plant foliage gets wet, as it can attract pests and fungal issues.
4: Fertilize appropriately!
Too many times, I see people go about fertilizing their daylilies completely wrong. Feeding your daylilies can boost their blooming potential significantly. Apply a balanced, slow-release fertilizer in early spring as new growth emerges.
If you want, you can reapply fertilizer later on in the season to achieve a second flush of blooms.
Just make sure that you don’t go overboard with fertilizer use and mess up the nutrient composition of your soil entirely. In case of overuse, the roots are the first to get badly damaged.
And if you’re working with other flowering plants too, take a look at how to fertilize geraniums properly.
5: Divide overcrowded clumps
Over time, daylily clumps can become somewhat crowded, leading to diminished blooming results. Therefore, I’d suggest spreading out and dividing your daylily plants every 3-5 years.
Ofcourse you will need adequate space in the garden as well as resources to pull this off optimally, but it’s definitely worth considering for healthier, completely rejuvenated daylily cultivars.
6: Choose reblooming varieties
Opt for varieties like ‘Stella de Oro’, ‘Happy Returns’, and ‘Pardon Me’ that are known for their ability to bloom repeatedly. With these, you can ensure continuous color well into late summer.
My mom is actually a fan of this method and regularly plays around with different daylily varieties to figure out which ones will rebloom and which won’t. Give it a shot; you’ll definitely find a few varieties that are worth working with in your garden.

7: Rejuvenate foliage mid-season
Although this may sound counterproductive at first, cutting back your daylily foliage 4-5 inches above the ground can actually produce beneficial results down the line.
It will help encourage fresh, new growth and flower production, giving the perennial a much-needed boost towards rejuvenation. Ensure proper watering and hydration after cutting back to allow for proper recovery and regrowth.
8: Monitor for pests and diseases
Believe it or not, I’ve perhaps dealt with 15 major pest infestations in my garden throughout the course of my journey! A good percentage of these infestations took place in my daylily patch because these perennials are just so vulnerable to them.
You definitely want to closely monitor your daylily plants for pests and spreading diseases. Keep an eye out for subtle signs, strange marks, or patterns that could signal the start of some major trouble. Maintain good air circulation around your daylilies and avoid getting their leaves wet whenever you water them.
And if petunias are part of your garden too, these simple mid-season tasks can help keep them blooming beautifully alongside your daylilies.
Let’s Conclude
But, before you leave, also take a look at how to deadhead geraniums, they benefit from a similar mid-season refresh to keep blooms going strong.
Like I mentioned earlier, achieving continuous blooms in your daylily plants is actually fairly simple if you know how to do things right. Daylilies are not the most delicate plants and can actually withstand a ton if you give them the right nutrients and fulfill their growth requirements in the right phases.
Controlling tons of variables at a time can be challenging, but taking one step at a time and making adjustments to your care routine slowly can make all the difference in the world. By going about things strategically, you can achieve repeat daylily blooms even in late summer, which most people consider to be the end of their blooming period.
what does the day Lily ovary look like?
Hi Bev! 😊 The ovary on a daylily looks like a small green pod right behind the flower, it’s where the flower connects to the stem. After blooming, if it’s been pollinated, that little pod starts to swell and forms a seed pod. I usually snip them off if I’m not saving seeds so the plant puts more energy into blooming again!
Thank you for explaining that 💕
Hi Debbie 🙂 You’re very welcome. I’m glad it helped. 🩷
Very good advice thank you
Hi Joan! 😊 Thank you so much. Glad it was helpful, wishing you tons of fresh blooms this season!
So do you give them a haircut after they are done blooming and fertilize them with a slow release at that time? It’s now mid August here in Mid Michigan and most of my daylilies are done blooming. It this to late to trim and fertilize?
Hi Rebecca!😊 You can still give them a light trim now. Just remove the spent flower stalks and any yellowing leaves, not all the foliage. I skip fertilizing this late and wait until spring so the plants focus on storing energy for next year.

Hi Ronal! We wrote a whole post on that! 😊 Here’s the link if you want to check it out: 9 Colorful Lawn Alternatives That Replace Grass Beautifully. Lots of great ideas in there!
We had a big storm with large hail that almost destroyed my Stella o Dora daylillies. All the blooms are gone. What do you suggest?
Hi Terry 🙂 I’d trim off the broken flower stalks and badly damaged leaves, then leave the healthy foliage so the plant can keep feeding itself. Stella de Oro is pretty tough, so with steady watering and a little cleanup, it may still push some new growth or rebloom later.
What are the best flowering plants for a balcony garden with the exception of geraniums? The balcony gets the afternoon sun.
Hi Flavia 🙂 For afternoon sun on a balcony, I’d try petunias, calibrachoa, lantana, zinnias, verbena, or dwarf daylilies in containers. Just keep an eye on watering, because balcony pots can dry out fast in hot afternoon sun.
I got some clippings from a friend and planted them last fall. Most of them did not have flowers this spring and some of the foliage is now turning yellow. What could be the problem ?
Hi Theresa 🙂 Since they were planted last fall, they may still be settling in and putting energy into roots instead of flowers. Some yellowing can happen from transplant stress, too much water, too little water, or older leaves naturally dying back. I’d keep them evenly watered, make sure they get plenty of sun, and give them more time before worrying too much.
If daylilies need 1” of water per week, how do I determine how much that is? Please help!
Hi emrogers1957 🙂 An easy way is to set a tuna can or small straight-sided container near the daylilies while you water. When it has about 1 inch of water in it, that area has gotten enough. Rain counts too, so if you get a good soaking rain that week, you may not need to add much.
