Do Daylily Spread?| What You Should Know About This Plant!

Daylilies are common to quickly grow and spread into large clumps, which eventually causes them to bloom less frequently. Your daylilies may need to be divided every few years, especially if you notice a decrease in blooming. Division requires a strong spade, which you may find at home improvement centers or gardening supply stores. Large clumps need to be divided into two, just like the rest of your plants require the same. You can also take advantage of how fast daylilies grow and separate some seeds from another plant, ready for it all within one season. They can generally reproduce themselves quickly with little work on your part.

Tips in Dividing Daylilies

  • In the growing season, you can divide daylilies at any time. But if you want to have blooms next year, divide them right after they flower.
  • For things to go well, you should dig up the whole clump of daylilies, cut the foliage back to about 6 inches, and pull or cut the entire thing up with a sharp blade or tool like a rake. Each piece should have a lot of stems (or fans of leaves) with roots.
  • You can also use a sharp shovel to divide plants without digging them up in overcrowded beds, but this method gives you less control over the size and quality of the divisions you create.
  • Just like a potted daylily, plant the divided pieces in soil that has been amended with compost. Until the new plants have established themselves, make sure to give them plenty of water. Don’t worry. You’ll have more daylilies than you know what to do within time, so don’t worry about throwing away any unhealthy pieces.

Is It True That Daylilies Grow Quickly?

Daylilies grow at different rates depending on a variety of factors.

Plant Medium

Daylilies tend to grow more in-ground than in pots. It is possible to grow daylilies successfully in pots, which is a popular choice for those with smaller spaces who want to brighten their balcony with flowers. Although these flowers grow more slowly in containers than they would if they were planted in the ground, it is essential to remember that they do produce more slowly in containers.


Flowers can grow more slowly if exposed to cold winters where they are planted. In contrast, those who live in tropical areas will see their daylilies grow more quickly because they won’t face the cold winters of the northern hemisphere.


Inadequate fertilization is yet another important consideration that you should take into consideration. The growth rate of your daylilies will be slower if you do not fertilize them regularly. The use of proper fertilization will result in your flowers growing at a faster rate than they otherwise would.

Some sources have claimed that fertilizing daylilies with high doses of ammonium chloride leads to rapid growth. Although this does happen in some instances, it is not the norm for most gardeners. Every year or spring-flowering plants grow more rapidly than fall flowering plants because they can use up oxygen faster and spend less time pushing leaves through stems. Also, always water your plant when it’s almost halfway dry, so don’t overwater a plant if it’s wintry outside.

Best Growing Conditions

You should make every effort to provide these perennials with the optimal growing conditions possible. As a result, they should be planted in an area where they will receive at least six hours of direct sunlight each day – a partially shaded area should be sufficient for most varieties. Also, make sure that the soil you plant is of high quality. However, although daylilies can thrive in many soil types, adding compost or peat moss to clay or sandy soil will improve growing conditions. By overwintering daylilies in a warm environment, you can ensure that they grow throughout the winter.

To improve the growth performance of your daylilies in the spring and summer, make sure to give them plenty of water. These flowers are drought-resistant and can withstand prolonged periods of drought. However, a lack of water during the spring and summer months can have a negative impact on the size and number of blooms produced.

Growing Space

Depending on the variety, some daylilies bloom faster than others, so be sure to give them plenty of space to spread and thrive. When planting, be sure to leave an adequate distance between each one. When growing miniature daylilies, the recommended spacing ranges from 16 to 24 inches apart. The recommended spacing for larger daylilies is 18-30 inches.
