Highlights From North Dakota State’s 2019 Bedding Plant Field Trials

North Dakota State University’s (NDSU) 2019 bedding plant trials consisted of more than 200 cultivars. The trials are located at the NDSU Horticulture and Research Gardens in Fargo, ND.

The beds were planted May 29 and 30 with the help of Master Gardener volunteers. They were hand weeded, and were fertilized three times during the summer with a foliar fertilizer (12-4-8).


The weather for June, July, and August was average for temperature, but above average for precipitation. July had 2 more inches of rain than normal, while August was an inch above the 30-year average.

Aphids were a problem on the ornamental peppers in July, but ladybugs arrived to take care of that problem. No other pest was bad enough to apply any pesticides.

Plants were evaluated on July 30 and September 6 for size (average height and spread), bloom, vigor, and uniformity.
