The daylily is a decorative flowering plant whose colorful funnel flowers are even edible. But not only that, the perennial is also very easy to care for.

Perennials are undeniably particularly decorative bright spots in the garden. Their flower colors and shapes are immense and surprise the hobby gardener every season for the season. Quite a few of them are even edible and enrich numerous salads and desserts with their subtle aroma or decorate the plate of wonderful dishes. The day lily (Hemerocallis) also flowers with such advantages. This grass tree plant is an undemanding, yet popular perennial for the garden and planters.

Short portrait of the day lily

The daylily currently has around 65,000 different varieties. This is thanks to the creative skills of the breeders. Depending on the variety, the first flower stalks will slide up from the grassy nest in May. Elongated flower buds then branch out on the stems and unfold in a funnel shape. Depending on the variety, the flowers can be single-colored or multi-colored. The color palette ranges from yellow, orange to red and violet.

The name day lily suggests that the individual flower does not shine for more than a day. However, because new buds break open every day, the flowering time takes longer overall. This can last up to six weeks. If you cleverly combine early and late blooming varieties, the bloom will last until September.

The best location for daylilies

A place in the sun is ideal for the day lily. The plant also accepts a half-shady spot. However, you should then make sure that it does not get too little sunlight. Young daylilies are difficult to develop in these locations or die entirely.

As for the garden floor, the day lily is quite frugal. The floor should be loose and permeable. If you then add some compost to the soil, the planting site is perfect.

This is how the day lily is planted

You can plant the day lily from April to October, whether in the bed or in a bucket. Spring is advantageous for planting when the danger of frost is already over. After all, the perennial can gain a foothold from this time until autumn and develop vigorously.

Use the perennial so that its roots are only about 2 centimeters deep in the ground. Then press the planting area and water your young plant well. In the first few weeks, make sure that the floor does not dry out. Water it only moderately. Too much moisture can be harmful because it can cause waterlogging, which leads to root rot. To prevent the moisture from evaporating too quickly, apply a layer of bark mulch to the planting site.

How to properly care for the day lily

To water:

The day lily also tolerates dry periods and gets by with the weather-related rainfall. However, the perennial develops a particularly vigorous bloom if you water it regularly from April to June as soon as the rain is waiting for you again. In addition, more buds form on the flower stems. It doesn't matter whether you use rainwater or use calcareous tap water.


You are on the safe side if you have enriched the soil with compost before planting. This completely covers the nutritional needs for the day lily in the first year. From May to mid-June of the following years, gently fertilize the location of your flowering perennial. Compost or an organic slow-release fertilizer for flowers are suitable for this. The best thing to do is to follow the dosage instructions on the fertilizer packaging. Daylilies in the bucket are fertilized with a liquid fertilizer for flowering balcony plants. The dosage must also be observed here.

The fertilizer bag will then remain in the shed from the end of June. If you fertilize later, it will damage the plant because it cannot optimally adjust to winter.

Rear section:

In a nutshell: You do not need to cut daylilies. Only withered and dry flowers or damaged leaves should be picked. Likewise, you should pull the withered leaves off the ground in spring before the new shoot begins.


The perennials survive the cold season without winter protection. Only the container plants need to be protected from the freezing cold. On the one hand, you can pack the planter with fleece, straw mats and jute sacks so that the soil does not freeze through. On the other hand, take the bucket to a protected place, for example in a frost-free garage. Then you should make sure that the soil in the bucket does not dry out.

Important: In a frost-free phase, you should gently water your perennials in the potted planters.

Detect and fight diseases and pests

Maintenance errors are usually the cause of diseases on the plant. So it happens from time to time that day lilies in the tub are attacked by root rot. Act beforehand and water the crop only moderately. If the disease occurs, remove the affected root parts and change the substrate.

From time to time, a voracious pest targets the flowering perennial. It is the daylily gall mosquito. She lays her eggs in the flower buds. The larvae then eat their way through the delicate plant tissue, deforming and destroying the bud as well as the desired flower. Remove infected buds immediately and dispose of them in the household waste.


The daylily with its flowers is a decorative perennial in the garden. Their edible flowers are also used in the kitchen. The flowering plant loves the flowering plant both in the garden bed and in the tub. It thrives on a loose and well-drained soil.

You should water the day lily regularly during its development phase. She thanks you with strong flowers. Otherwise, it is frugal and gets along with weather-related rainfall. In the cold season, potted plants need winter protection.
