Tips For Growing Daylilies (Every Flower Garden Needs Them)

To say I love daylilies is an understatement. Okay, I think I’ve said that before, so maybe it’s true about flowers in general. Anyway, daylilies are one of the easiest, low maintenance perennials to grow. They are tough plants and can be ignored and they’ll be fine, but you’ll be rewarded with outstanding blooms and the best results, if you give them lots of love, including good growing conditions. I have a bunch of daylily goodies to share with you, so let’s get started with some great Tips for Growing Daylilies. 

A Little Education About Daylilies (Botanical Name = Hemerocallis)

We are NOT talking about hemerocallis vulva (a/k/a orange ditch lilies) here. Sometimes when gardeners hear “daylilies” they immediately tune out, because they are thinking all daylilies are invasive and ugly like the common orange ditch lily.  Sorry, if you have ditch lilies and love them, I don’t mean to offend you. From a daylily collector’s perspective, I’m here to tell you all daylilies are NOT the same. There are so many wonderful varieties of daylilies with beautiful flowers that it’s easy to get addicted. Ask me how I know.

Daylilies are NOT grown from bulbs and are not related to true lilies (lilium) that are grown from bulbs. The roots of a daylily plant are fibrous, clumping, fleshy masses that store water.

Each individual flower on a daylily plant blooms for just a day, thus the name daylily.

Reblooming Daylilies

I have quite a collection of daylilies (over 90 different varieties) and my favorites are the rebloomers. A reblooming daylily will start with it’s first big wave of blooms. When those blooms are finished, it will take a rest and send up more blooms a few weeks later. In my Zone 4b gardens, I don’t always get rebloom, but I find that lots of rebloomers are constant bloomers.

Any of the “returns” series fall into that constant bloomer category. Happy Returns is probably the most popular in this category. There’s also Rosy Returns, Red Hot Returns, Fragrant Returns, When My Sweetheart Returns, Passionate Returns, Stephanie Returns, etc., etc. This sweet little Passionate Returns is one of my favorites this year. Stella d’ Oro daylily is a very popular reblooming daylily as well.

Tips for Growing Daylilies – Where to Plant

Although daylilies can grow in poor soil, they grow best in fertile, well-drained soil. Also, daylilies do best in full sun (6 or more hours of sun), but will also be okay in partial sun or partial shade (4-6 hours of sun). Remember daylilies (and most other perennials) can be moved to a different location in your gardens if they aren’t doing well in the area you have them planted.

Tips for Growing Daylilies – How to Divide and Plant Daylilies

Daylilies will grow for many years just fine without being divided. After about 4 or 5 years when the plants are getting quite large, you may want to consider dividing your daylily. Sometimes if the plants get to overgrown, they will bloom less.

The best time to divide daylilies is in early spring when they are first emerging from the ground, or in late summer / early fall after their bloom cycle is complete.  The best way to divide daylilies is to dig up the entire clump. I love this garden fork for digging up daylilies. I have less damage to the clumps when I use it over a shovel. Then cut through the crown of the plant with a sharp knife, or pull the clump apart into manageable pieces. Before replanting, cut the foliage back to a height of 5 or 6″.  And, now you have new plants to share or replant in your gardens. If you need additional help dividing and transplanting your daylilies, check out Tips for Transplanting Perennials.

Tips for Growing Daylilies – How to Plant

Whether you are planting or replanting a division of a daylily the directions are the same. 

• Dig a hole a little deeper that the root mass of the daylily.
• Next mound up soil in the middle of the hole.
• Spread the daylily roots over the mound (see the image above) and fill in the hole surrounding the roots with the soil you dug out. It’s a good idea to add in organic matter like compost at this point. You can add slow release fertilizer too if you so desire.
• The crown of the plant needs to be just below the surface of the soil or ground level and not buried too deeply.
• Water your transplant well, so it starts developing a strong root system. For the first year, give your new daylily special care and it will reward you with many beautiful flowers in the years to come.
• You should begin to see new growth within a week or so.

Tips for Growing Daylilies – Care & Maintenance

Watering & Mulching for Daylilies

During their first growing season, daylilies should be watered during dry weather; and for several weeks after they are planted. This will help them get established more quickly. Rather than watering every day, water twice a week if it doesn’t rain, but water deeply, making sure the water soaks down into the root zone. Mulching around daylilies will help keep the soil moist and help to control weeds.

Daylily Care – Deadheading

Each daylily flower lasts just one day. To keep the plants looking their best, snap off the spent flowers, but be careful not to disturb nearby flower buds. The easiest way to deadhead is by using garden shears or bypass pruners.

Below, in the before and after picture of a Fairy Tale Pink Daylily, you can see the difference between seed pods and new buds. Unless you have the patience to start daylilies from seed, you will also want to clip any seed pods. By clipping the spent flowers and the seed pods, the daylily will put it’s energy into making new flowers and not put it’s energy into seed production. If all the buds have bloomed, the flower stalks can be cut down to the base of the plant.

As you are deadheading, go ahead and remove any dead foliage or discolored leaves. Just a side note here about the foliage of daylilies. Some daylily varieties are more prone to yellowing or browning foliage that others. I’ve noticed in my gardens that if we have an exceptionally hot and dry summer, some of my daylilies foliage looks awful and some are fine. I haven’t been able to find an explanation of this other than there’s nothing wrong with your daylily, it’s just the nature of some varieties. If you have a daylily with dying foliage, just clip the foliage as much as you need to. It will not hurt the plant.

Fertilizing Daylilies

It isn’t necessary to fertilize daylilies and I didn’t fertilize at my last home because the soil was awesome. At my current home, I fertilize my daylilies in the spring with a slow release fertilizer. I simply sprinkle Osmocote around the base of the plant and work it into the soil a bit, before applying a fresh layer of mulch. Adding this fertilizer has made a huge difference in my daylilies and the number of blooms on each plant. 

There are many daylily groups on Facebook and I’ve seen the daylily pros recommend using Milorganite around their daylilies. I will definitely be trying that this year.

How to Extend the Blooming Season, or Get Your Daylilies to Bloom Longer

As a recap of the above information, to get the most blooms from your daylilies, or to get your daylilies to bloom longer:

• Be sure your daylily plants get enough water. If you haven’t had enough rain, water your daylilies.
• Fertilize your daylilies with a slow release fertilizer in the spring.
• Deadhead your daylilies.
• Look for reblooming varieties of daylilies.
• Plant a variety of daylilies that are early bloomers, mid-season bloomers and late season bloomers. Buying a variety of plants with different bloom times will ensure that you have daylilies blooming late spring through late summer.

What if my Daylilies Don’t Bloom

This is another question I see – How Do I Make my Daylilies Bloom? Let’s do a little troubleshooting. Go through this list and see if you can pinpoint the problem and then take steps to remedy it.

• Is your daylily getting enough sun? Daylilies love sun! Do you need to relocate your daylily to a sunnier spot in your garden?
• Is your daylily getting too large? Generally daylilies don’t have to be divided for about 4-5 years, but if they get too big, their blooms will diminish. Go back up and read the section on dividing your daylily.
• What is your soil like? Daylilies aren’t too picky, but they do like to be fertilized. If your daylily isn’t crowded and is getting plenty of sun, give it a boost of fertilizer.

Daylily Care After Blooming

I hear this question all the time – what should I do with my daylilies after they have finished blooming? First of all, be sure all the spent blooms and seed pods have been removed from the plant (see deadheading above). Once the scapes (the long, hard stems) no long have any new buds left, they can be cut back to the base of the plant to keep the plants looking tidy. Like we said above, many daylily varieties are reblooming varieties and after taking a little break, the plants will rebloom. You have your best chance of rebloom if the daylily plant is well cared for. At this point, you can give the daylilies another scoop of Osmocote, or Milorganite.

Tips for Growing Daylilies – Buying Online

I’ll buy daylilies from any garden center or any place they catch my eye, but my favorite place to purchase daylilies is online. If you really want to add some different varieties to your collection, shop online. Some of my favorite online daylily sellers are Oakes Daylilies and Smokey’s Gardens. I’ve had awesome results and received great customer service from both companies. If you have a favorite online daylily source, please leave a comment below and let us know.

A few things to remember when ordering online. Daylilies are usually sold by fans and they are shipped as bare root daylilies with only 3 or 4 inches of leaves and stem. They come with planting and growing instructions, and I would recommend following those instructions.

Daylily Collections

Are you a collector of daylilies like me? In order to keep track of all the daylilies I have, I created a Plant Inventory sheet that I keep in my Garden Journal. If you’re interested in getting a copy, I’ve included it in my library of Free Gardening Printables.

This photo of Inherited Wealth was taken in the evening just as the sun was shining it’s last few rays.

Lavender Rainbow is really thriving this year. It’s one of the many daylilies I moved from my former home.

Heavenly Angel Ice is a new addition this year and my first ever spider daylily.

Like most other perennials, it takes daylilies a year or two to get established and take off, but once they do, they’ll bloom reliably for many years and just keep getting bigger and better with each passing year. That’s it for the Tips for Growing Daylilies, but I do have some more pretties I’d like to share with you.

Growing Daylilies in Pots

Do you grow daylilies in planters? Every summer I go overboard purchasing new daylilies that I don’t already have even before I know where I will put them in the ground. The best thing to do when this happens is to plant your daylilies in containers. For something completely differently, it’s also fun to plant daylilies in pots with other annual flowers.

If you live in a colder gardening zone and you have daylilies in containers, be sure to bury the container; or, remove the plant from the container and plant it in the ground before winter sets in.

Daylily Eye Candy (a/k/a Daylily Photo Gallery)

In the daylily images below, the name of the daylily is in the caption below the picture.

 

Pure and Simple is one of the first daylilies to bloom in my gardens.

One of my favorites, because my sister sent it to me, Wild Horses.

This daylily, First Lady Barbara, was a freebie from Oakes. I’ll take free!

Daylily Fall Care

Again, daylilies are not too picky. If you have the time and desire, you can cut daylilies to the ground in the fall. In colder zones, it’s okay to go ahead and mulch them. If you don’t have time in the fall, you can do nothing. Daylilies are very hardy and survive the worst of winters here in my zone 4 gardens. Fall is also a great time to divide and transplant daylilies.
