Calibrachoa prefers acidic soil. Add peat moss to the soil before planting to increase the acidity. Apply 1 inch of mulch around the plant to conserve moisture. Replace the mulch as it decomposes. Fertilize with a slow-release fertilizer.
Calibrachoa tends to rot in soggy soil and is extremely tolerant to drought. Water the plant once a week, increasing to twice a week in extremely hot weather. Apply a 20-10-20 fertilize once a month, watering immediately afterward.
Trim back foliage in midsummer to increase blooms. This plant is very tolerant of pruning and produces new growth very quickly.
Though calibrachoa can remain outdoors in U.S. Department of Agriculture planting zones 9 through 11, in other areas of the country it must be brought indoors during the winter. Bring calibrachoa inside before the first frost, keeping it in a warm, stable environment until it can be replanted outside in the spring.
