You can simplify the knowledge on how to grow daylilies in pots into two sections. To avoid drawbacks during the plant’s vulnerable age, you can also grow them in the greenhouse before poting. Nonetheless, take comfort in the fact that daylilies are highly adaptable and will thrive well in growing zones 3 to 9.
Daylilies tend to endure different challenges in the garden smoothly, making them a favorite among gardeners. There are also different varieties to choose from, ranging from evergreen and deciduous. With proper preparation on growing daylilies, you should enjoy these plants in pots as much as those who produce them directly in the ground.
Comprehensive Guide On How To Grow Daylilies In Pots
Step #1. Planting
The advantage of growing daylilies in pots is that you are not limited in the location or season in doing it. You can use a greenhouse for these potted plants, especially when you have no stable area for your young plants. While daylilies adapt quickly to their location, you still want to place their pots somewhere not too challenging until they have established themselves.
For potted daylilies, it would be advantageous to grow them in the greenhouse using division. Afterward, you can plant the rooted daylilies in a pot with compost and potting soil mix. You want the pot’s rim and the medium’s surface to have around 2 inches of space, and some gardeners add rocks at the bottom as well.
Adding rocks at the bottom of the pot is useful for tall daylilies. Remember that over time, these pants can fall over the pot, especially during the blooming season. One of the key points in growing daylilies in pots is anticipating these small limitations as the plants grow.
Setting and positioning
If your container is big, you can place a daylily in the middle and have others around the edge 18 inches apart. You want to plant them at the same depth as their previous growing area. Ensure that the daylilies are well-supported, with soil around their roots.
You can also use a greenhouse to keep these pots and not just grow the daylilies for container planting. You want them to receive 6 hours of sunlight to encourage healthy development. The greenhouse is useful because you need the pots to be protected from challenges such as wind that can tip the pots.
Step #2. Maintenance
Perhaps one of the reasons why gardeners love daylilies is that they can endure common growing problems easily. They don’t require an extensive list of maintenance practices, even those that you have in pots. However, don’t forget that caring for daylilies will ensure that they can withstand potential challenges.
Watering and fertilizing
Daylilies are drought-tolerant, but you still want to keep them hydrated. Maintaining the moisture of the pot’s medium will help the plants bloom continuously. Upon planting, you want to soak the soil and let it drain for the first eight weeks.
You can then water weekly, depending on the conditions. The summer in your area can quickly dry the pots, so anticipate this problem beforehand. You can also add compost and mulch over it to preserve soil moisture while also adding nourishment and preventing weed growth.
How to fertilize daylilies in pots? A 5-10-10 slow-release fertilizer on top of the container should suffice for potted daylilies. You can also help with flowering by feeding in late summer.
However, avoid using high-nitrogen fertilizers because they are not supportive of flowering but foliage growth.
Pruning and dividing
Simple pruning practices will help with bloom production and plant health. Start by removing faded flowers to extend and encourage flowering by preventing seed development. After the blooming season, you can also cut the stalks back to the ground to rejuvenate the potted daylilies.
Like most container plants, an excellent propagation method that will also maintain daylilies in pots is division. This will prevent the plants from getting overcrowded, and you can do this when the plants are growing in early spring.
How To Divide Daylilies
You must divide daylilies every three years during early spring when new growth appears. You can also do it in late summer to fall or at the end of the growing season, as long as you can ensure that they have established themselves before winter. Take out the entire root system from the pot and remove the soil to make division easier.
Section the clump by hand and aim to have three fans of leaves per section and a good number of roots. You want to remove any damaged roots by cutting or throwing them away. You may also need to use shears to do the separation.
Container planting and taking advantage of the greenhouse are excellent ways to have beautiful flowering plants like daylilies. You can learn how to grow daylilies in pots in two easy steps and take comfort that these plants are beginner-friendly to cultivate. It’s best to start or propagate daylilies in the greenhouse and transplant them to pots.
Use a mix of potting soil and compost, and then place the pots somewhere bright but out of the wind to tip them over. For maintenance, ensure soil moisture to help the daylilies bloom. You can also use low-nitrogen fertilizers to encourage bloom development further
Deadheading and cutting back the daylilies after flowering will rejuvenate them for the next season and extend or encourage blooming. After some years, you can prevent overcrowding by dividing potted daylilies.
