How to care for Garden Petunia
Water
Water Petunias deeply once a week, allowing the soil to almost dry out between waterings. During hot, dry periods, more frequent watering may be necessary. Ensure good drainage in pots and flower beds to avoid waterlogging which can lead to root diseases.
Light
These plants require full sun to promote optimal growth and flowering. Placing them in a spot with at least 5 to 6 hours of direct sunlight daily is ideal. While they can tolerate partial shade, too little light can lead to weak plants and fewer flowers.
Nutrients
For optimal growth and blooming, Petunia × atkinsiana should be fertilized every two weeks with a balanced, water-soluble fertilizer. During the growing season, high phosphorus content in the fertilizer can help promote more abundant blooms. Avoid over-fertilizing, which can lead to lush foliage with fewer flowers.
Temperature
Petunia × atkinsiana plants prefer warmer temperatures and are frost-sensitive. They thrive best when daytime temperatures are between 70 to 85 degrees Fahrenheit and night temperatures do not dip below 50 degrees Fahrenheit. Protect or bring containers indoors if unexpected frost is forecast.
