Addressing Signs Of Disease In Petunias
Along with pest infestations, petunias are susceptible to various diseases that can hinder their blooming capabilities. Two common diseases that affect petunias are powdery mildew and root rot.
Powdery mildew appears as a white, powdery substance on the leaves and stems of petunias. It thrives in humid and stagnant air conditions, often caused by overcrowding or lack of proper air circulation. Applying appropriate fungicides can control powdery mildew and prevent its spread to other plants.
Root rot is caused by excessively wet soil and poor drainage, leading to the deterioration of the plant’s root system. Signs of root rot include wilting, yellowing leaves, and a foul smell emanating from the soil. Improving drainage by amending the soil or using raised beds can prevent root rot. If root rot already exists, removing affected plants, improving drainage, and treating the soil with fungicides can help in the recovery process.
Special Trimming Techniques For Supertunias
Supertunias, a popular variety of petunias, require special trimming techniques to keep them blooming throughout the summer. It is important not to cut off more than 20% of the plant when trimming Supertunias. Excessive pruning can shock the plant and hinder its ability to produce new flowers.
To maintain the desired shape and size of Supertunias, it is beneficial to trim longer stems that may be extending beyond the plant’s overall form. This trimming technique helps create a cohesive and compact appearance. Additionally, cutting back the ends of branches by 20% can stimulate new growth, resulting in a continuous display of vibrant blooms.
- Unlike other petunias, Supertunias do not require deadheading as they are classified as self-cleaning. This means that old flowers will naturally drop off without intervention, further reducing the maintenance required for these varieties.
Key points:
- Trim Supertunias by cutting off a maximum of 20% of the plant to avoid shocking it.
- Trim longer stems to maintain the desired shape and size, creating a cohesive and compact appearance.
