Yes. Deer browse impatiens, including their leaves, flowers, and tender growth. Do not treat an unprotected planting as deer-proof. NC State Extension’s common impatiens profile specifically notes deer browsing.
The amount of damage varies with local deer pressure and access to the plants. A bed left untouched last year can still be browsed this year. A plant-resistance rating describes observed damage risk; it does not establish that deer will always choose another food first.
Confirm what is damaging the plants
Look at the whole planting, not just a missing flower. Note when damage appears, whether shoots have been eaten off, and whether tracks or droppings are present nearby. A wildlife camera can help if repeated damage remains unexplained.
Other animals and plant-health problems can also damage impatiens. Holes in foliage, wilting, leaf loss, and missing shoots are not interchangeable symptoms. Do not choose a deer repellent to treat an unidentified insect, disease, or watering problem.
Use a barrier where the flowers matter most
Physical exclusion is generally the most dependable way to keep deer from a vulnerable planting. Iowa State University Extension discusses fencing and other protection methods. The design needs to suit deer, the size of the enclosed area, and local conditions; a short decorative border is not sufficient merely because it surrounds the bed.
For a few containers, relocating them behind an effective existing barrier may be more practical than fencing a whole yard. Hanging baskets only help when deer cannot reach the plants from nearby ground, steps, or other access points. Hanging a pot is not a guarantee of protection.
Keep barriers maintained and gates closed. If using mesh, install it securely and check for loose material or entanglement hazards. Make sure flowers do not grow through the barrier into browsing reach. Check local requirements before installing a substantial fence.
Use repellents with realistic expectations
A repellent labeled for deer on ornamental plants may reduce browsing, but effectiveness varies. Follow the label for application, plant compatibility, reapplication, and precautions around people and pets. Do not invent stronger concentrations or combine products.
New growth and weather can affect protection. University of Maryland Extension describes how rainfall, new foliage, deer density, and the product influence repellent performance. If damage continues, reassess access and protection instead of assuming another spray will solve it.
Companion herbs or ferns are not a dependable protective wall around impatiens. Similarly, a plant that tolerates shade or resists a particular disease does not thereby become deer-resistant.
Care after browsing
Protect remaining growth first so the plant is not eaten repeatedly. Remove broken or clearly dead material carefully, retain healthy foliage, and keep watering appropriate to the site. Avoid a heavy fertilizer application intended to force an immediate recovery.
Whether an individual plant recovers depends on the remaining stems and roots, its overall condition, and the growing season left. Replace badly damaged plants when necessary, or choose a locally suitable alternative with lower browsing risk. Keep expectations realistic even for plants described as deer-resistant.
