what causes flowers to wilt
Lack of sun can also lead to the wilting of petunias. Petunias prefer full sun and will produce the most flowers if they get it. They can survive in partial sun as long as they get 5 to 6 hours of direct light every day. If your petunias are in the shade, that might be your problem. Petunia wilting problems can also be a sign of insect or fungal issues.
Like lots of plants, petunias respond to a lack of water by wilting. Donât just water them more, though! Wilting petunia flowers can also be a sign of too much water. Always check the soil around your petunias before watering â if the soil is still damp, donât water it.
