Supertunia petunias are vigorous with slightly mounded habits that function as both fillers and spillers in containers. THey are also excellent landscape plants, best suited to be placed near the front of beds. They have medium to large sized flowers.
Plants may be trimmed back with a sharp pair of scissors or pruning shears at anytime, although this is not usually necessary. Plants may flush out of flower if night temperatures begin to stay in the upper 70’s or above. If this happens a light trim to shape them would be good. The trim will increase branching and will result in more flowers once the temperatures fall and the plants begin flowering again.
A yearly application of fertilizer or compost on garden beds and regular fertilization of plants in pots will help ensure the best possible performance.
