watering
Sneezeweed should be watered every 1-2 weeks during the warmer spring and summer months, but it may require more frequent irrigation during extreme heat. Water thoroughly when the soil becomes dry to the touch. Make sure the soil drains properly, and avoid overwatering, as this could cause root rot. During the fall and winter months, water Sneezeweed only when the soil becomes very dry. It is best to water the soil around the base of the plant and not the leaves.
sunlight
Sneezeweed (Helenium amarum) is a plant species that prefers full sunlight. During the blooming season, provide at least 6 hours of direct sunlight each day. In a colder climate, this may increase to 8-10 hours per day. During the winter season, as days get shorter, the amount of sunlight will be reduced. Provide the plant with at least 4-5 hours of direct sunlight in order to provide the amount of light the plant needs to promote healthy growth.
pruning
Sneezeweed (Helenium amarum) should be lightly pruned throughout the growing season. Deadheading or cutting off spent flowers can encourage a new flush of blooms and keep the plant looking tidy. If the plant becomes unruly or overgrown, more extensive pruning can be done in early spring, just before new growth begins. This will remove any dead or weak stems and help the shrub maintain its shape. Avoid pruning too much in 1 season, as this may shock the plant.

FAQ
Are Sneezeweed flowers suitable for bouquets?
Sneezeweed flowers are not typically used for bouquets due to their large size and bushy shape. The flowers are usually dried and used in other craft projects or for medicinal purposes. If you wanted to use dried Sneezeweed in your bouquet, they would provide a unique and eye-catching contrast against the other greenery in the bouquet.
Should Sneezeweed be planted in groups or individually?
Sneezeweed should be planted in groups, as groupings of this flower look the best in the garden. Planting them in groups will not only make them look more appealing but will also provide helpful cover for its shallow roots. Additionally, planting them in large groupings can help it to attract pollinators like butterflies and bees, providing a habitat where they can feed off the nectar-filled blooms. For best results, it's suggested to plant groupings of three to five plants for a lush, full look.
Is Sneezeweed resistant to deer damage?
Sneezeweed is a perennial flower with a resiliency to deer damage. It has a hairy leaf texture which deters deer from browsing on it and it produces a strong aroma that most deer tend to stay away from. The stems of the plant are also relatively tough, and not easily broken off. All in all, it is considered to be deer-resistant, but not completely deer-proof. It's important to monitor the plant to make sure it is not being overbrowsed and to take steps to protect it, if necessary.
