Growing Trollius

Although Globe flowers have a reputation as picky plants, a lot of gardeners would say otherwise. These lovely wildflowers are pretty easy-going if you manage to find the perfect spot for them in your garden or home. The most common mistakes among gardeners include providing improper growing conditions and general care. But no worries, you got this!

In terms of lighting, Trollius plants are very adaptable and will tolerate a wide range of conditions. These flowers grow at their best in full sunlight, but they can also do just fine in a partially shaded area. In both indoor and outdoor settings, grow your plants in a location where they can receive at least six hours of bright and direct light daily. If you live in a region with very hot summers, your babies will appreciate some protection from the harsh afternoon sun.

When it comes to temperatures, Globe flowers usually thrive in USDA hardiness zones 3 to 7. These plants prefer slightly warmer temperatures, but they will also tolerate frosty winter months without any issues. Make sure you keep your flowers away from extremely hot temperatures because they cannot handle them very well.

In general, Globe flowers are carefree plants that do not encounter many pest infestations or fungal diseases. Still, if you are growing your plants in dry climates or high humidity levels, powdery mildew can bother them once in a while. Poor air circulation or not enough sunlight may also contribute to the onset of this fungus.

Powdery mildew usually shows its presence through white or grey powder-like spots on the leaves, stems, or flowers. If you notice this sign on your plants, you should remove the unhealthy parts to prevent any future spread. Moreover, you can apply neem oil or a powdery mildew fungicide once every week until you manage to get rid of the fungus.

Planting Trollius

Trollius plants are self-fertile, growing without problems in loamy or clay soils and any pH level. However, these buddies will perform best in heavy, wet clay growing mediums that are rich in humus. They also do well in boggy and poorly drained substrates, so you should avoid dry soils at any cost.

During their flowering season, we recommend you deadhead your Trollius plants. This process consists of removing all spent blossoms to make room for new ones to appear. By doing this, you will have more flowers around to enjoy their charming presence.

Once their blooming period has ended, your Globe flowers will benefit from a balanced liquid fertilizer. First things first, you will have to cut back the plants’ foliage before feeding them. After that, you can fertilize your flowers once or twice, then let them be. These particular two steps will ensure vigorous growth and promote more flowers in the next year.

Watering Trollius

The process of watering these superb flowering perennials is piece of cake, especially for beginner gardeners! Trollius plants are big lovers of moisture, so you cannot possibly over-water them. After all, the worst thing you can do to these flowers is to deprive them of water.

The only seasons when you can skip watering for good are winters and cooler autumns. During this period, they usually become dormant and do not require supplemental irrigation.

To adopt a suitable watering routine, make sure you check the soil of your Globe flowers regularly. When the top inch (2.5 cm) of soil feels dry to the touch, you should provide your beauties with a nice touch of water. In regions with frequent rainfalls, however, these plants will not demand any extra effort on your part.

Propagating Trollius

With their unlimited beauty and easy-going style, Trollius plants can easily find a place in our hearts. Knowing this, it is absolutely normal to want more of these irresistible plants as your companions. And, of course, you can also gift these symbols of gratitude to your beloved family members or friends. Because everything is better when shared with others!

You can propagate globe flowers through stem cuttings or division without any problem along the way. For both methods, your experience in the gardening world is irrelevant. All you have to do is find your inner courage and follow our simple steps!

If you want to propagate Trollius plants through cuttings, you will need as many healthy stems as you can get. Look for healthy stalks and cut about 4-6 inches (10-15 cm) off them using a sharp, sterilized knife. Remove the bottom half leaves from each cutting and let the top half untouched. Dip the cut ends in rooting hormone before planting for optimal growth. With lots of sunlight and moisture, your cuttings will develop a healthy root system in several weeks.

Besides propagation purposes, globe flowers will really benefit from regular division once every year in spring. When their active growing season begins, you must dig out your plants and divide their roots into as many parts as possible. However, keep in mind that each root section should have at least one stem attached to it. Once you have the divided roots, transplant your tiny plants in their permanent location and care for them as before.

In Conclusion

When it comes to gardens with lots of sunlight and moisture, Globe flowers are among the favourites for most plant lovers out there. And why wouldn’t they be? As long as you meet their basic needs, these plants will surround you with cute flowers for a very long time. Now, the real question– which cultivar will be your next companion?
