I have several long planters lining my front porch. They each hold two 1x2ft. planters. In each planter I planted 2 zonal geraniums, and 2 sweet potato vines. Geraniums in back, sweet potato in the front. They look beautiful, and the sweet potato really took off, but even with my cutting it back every few days, it has affected the rigor of the geraniums. Last year when I planted the geraniums with millionbells they thrived---grew really large and bushy. This year, they are puny. I prefer the vine to the million bells because the calibrachoa got rather ratty by August.

Any suggestions for a substitute next year? OR, thinking maybe planting 4 geraniums and ONE sweet potato vine right in front in the middle would be better? The spot gets about 5-6 hours of full sun

Any thoughts?
Thanks so much,
Joanne
