Calibrachoa Growing Tips

Calibrachoa are one of the best choices for Indiana summers. They handle heat better than petunias and will keep blooming strong even as temperatures climb. They're a great option if you want something that still looks good into July and August.

The biggest thing to watch for is pale, light green leaves or noticeable veining. This is a sign the plant isn't getting enough nutrients—kind of like it's running low on energy. When this happens, flowering can slow down and the plant loses its rich color.

To keep them performing, feed regularly with a fertilizer like Jack's Classic Petunia Feed 20-6-22 or Miracle-Gro Water Soluble All Purpose Plant Food 24-8-16 once a week.

Good airflow is also important, especially in containers and hanging baskets. If plants are packed too tight or sitting in still, humid air, they can struggle more than they should.

Calibrachoa can get a little leggy mid-season. If that happens, a light trim and feeding will help them fill back in and often come back beautifully for fall.
