If you're thinking about adding these flowers to your home but aren't sure how to make them thrive, you've come to the right place! Below, we'll discuss how to grow daylilies, the best tips for care, and what to expect from these lively flowers.

What Are Daylilies?

Daylilies are perennials that are similar to lilies but not quite the same. Although daylily has the term "lily" in its name, daylily flowers belong to the Hemerocallis genus, and unlike true lilies, they don't grow from bulbs. Daylilies have beautiful trumpet-shaped blooms that only last a day. However, they have many flower buds, which means a constant display throughout the season. This unique feature sets them apart from lilies, which typically have larger, long-lasting flowers.

How to Plant Daylilies

Follow these tips for planting daylily flowers to ensure they have the best chance to bloom.

Prepare the soil.
Choose loose soil that's well-draining and contains organic matter. Incorporate compost to improve fertility and structure. Avoid waterlogged or compacted soil.

Dig the planting hole.
Dig a hole big enough for the roots and deep enough to cover the crown. The right size is about twice the diameter of the root system.

Plant daylily buds about 12 to 18 inches apart to prevent overcrowding.

Place the bulb.
Gently place the daylily buds in the hole and spread the roots. Align the crown to the soil level. Fill the hole with soil and pat it down gently.

Where to Plant Daylilies

The best place to plant daylilies is somewhere they can receive at least six hours of direct sunlight per day. While daylilies can handle partial shade, they generally flower best in full sun. When choosing a planting site, make sure to also consider spacing needs to prevent overcrowding and promote proper air circulation among the daylilies.

When to Plant Daylilies

The best time to plant daylilies is typically in the early spring or late summer to early fall. Planting in the early spring helps the daylilies to establish their root systems before temperatures get too hot. Planting in late summer to early fall gives them plenty of time to acclimate before winter. Avoid planting them in extreme temperatures, such as the peak heat of summer or the freezing temperatures of winter.

How to Care For Daylilies

Caring for daylilies involves a few key steps to ensure they thrive. These include:

Sun icon


Daylilies flourish in full sun. Give them at least six hours of direct sunlight to ensure optimal blooming. Providing your daylilies with some shade in the afternoon can be helpful if you live in an area with intense heat.

Soil Conditions

Plant daylilies in soil that's rich in organic matter and well-draining. Choose a soil that's fertile with a slightly acidic to neutral pH. Consider mixing the soil with compost to maintain fertility and enhance soil structure.

Watering icon


Daylilies need consistent moisture, especially during their active growing season. Water the soil deeply if it's dry, but avoid waterlogged soil. Add some mulch around the bottom of the plants to help retain soil moisture, prevent weeds, and regulate temperature.

Best Temperature

These are tough plants that can withstand most temperatures, but they generally grow better in moderate conditions.

Fertilizer icon


Daylilies don't need fertilizer if the soil is decently fertilized. However, you can promote stronger blooming by adding fertilizer in early spring before new growth starts and again after the first bloom cycle.

Deadheading Daylilies

Deadheading is an essential step in caring for daylilies and keeping your garden clean. To deadhead daylilies, pinch or snip off the spent flower stalks close to the base and make sure to remove the entire spent blossom. Regular deadheading throughout the blooming season encourages the development of new buds and promotes the continuous display of vibrant flowers.

How to Divide and Transplant Daylilies


Start by trimming the foliage to about eight inches for easier handling.


Dig up clumps.
Carefully dig up the clumps of daylilies and be gentle with the roots. Place them on a tarp for convenient transport.


Divide into healthy clumps.
Use a knife or spade to divide into smaller sections. Aim for healthy clumps with three to four fans each. Fans are the individual leaf and flower-producing units.


Replant your divided daylilies in soil that has organic matter. If you prefer container gardening, choose well-draining containers with fresh potting mix.

How to Prevent Pests

The best way to prevent pests is to remove dead foliage and debris from your garden regularly. Inspect your daylilies often to check for signs of pests like aphids or spider mites. If you find any, treat them with insecticidal soap or neem oil.

Common Types of Daylilies
