Petunias need regular watering, especially during hot and dry weather. Water your Petunias deeply once or twice a week, or when the top inch of soil feels dry to the touch. Be careful not to overwater, as this can cause root rot and other problems.
Petunias can be propagated by seeds or cuttings. Seeds can be sown indoors or outdoors in the spring, while cuttings can be taken in the summer or fall.
Petunias thrive in full sun but can tolerate some shade. They prefer well-drained soil that is rich in organic matter.
Petunias grow best in temperatures between 60 and 80 degrees Fahrenheit. They can be damaged by frost and extreme heat.
Petunias are vulnerable to pests such as aphids, thrips, and spider mites, as well as diseases such as powdery mildew and botrytis blight. To prevent and control these problems, keep the plants healthy and avoid overcrowding. Use organic insecticides and fungicides as needed.
