By now, most pansies are in the ground. Now it is time for winter care to improve their performance! UGA Extension has an excellent publication on growing pansies – Success with Pansies in the Winter Landscape: A Guide for Landscape Professionals. It provides info and the practices that help us get the most from our pansies.
- Once the weather cools and soil temperatures drop below 60° F, pansies grow better when fed a liquid feed program using a fertilizer containing at least 50 percent of its nitrogen in the nitrate form.
- Fertilizers containing more ammonia can be used more once soils warm in the spring – starting about March 15.
- Reduce fertilization during warm weather to control plant growth.
- Pansies grow best in soils with a pH of 5.4 – 5.8. Higher pH encourages boron and iron deficiencies while making plants more susceptible to black root rot.
- Removing frost-damaged and old and faded flowers improves the looks of the bed, encourages more flowering and can reduce disease incidence.
- You can trim lanky branches to produce stocky plants with more branches and flowers.
Several insects and diseases affect pansies. For help identifying these problems, contact your local Extension Office.
