As a gardening and landscaping expert, I can understand your concern about hollyhocks infected with rust. Rust is a common fungal disease that affects many plants, including hollyhocks. If you notice rust on your hollyhocks, it is important to take action promptly to prevent the disease from spreading further. Here are some steps you can take to deal with hollyhocks infected with rust:
1. Identify the infected leaves: Rust initially appears as small, orange or yellow spots on the leaves. These spots gradually enlarge and turn into rusty-brown pustules. As soon as you notice these symptoms, it is crucial to take action to prevent the spread of the disease.
2. Pick and destroy infected leaves: The first step you should take is to remove and destroy any infected leaves as soon as you spot them. This helps to prevent the rust spores from spreading to healthy parts of the plant or to nearby plants. Be sure to wear gloves while handling the infected leaves to avoid spreading the disease further.
3. Cut down infected stalks after blooming: Once your hollyhocks have finished blooming, it is advisable to cut down and destroy the infected stalks. This helps to minimize the chances of the disease overwintering and spreading to new growth in the following season. Use clean pruning shears to cut the stalks at the base and dispose of the infected plant material properly.
4. Remove fallen plant debris: Rust spores can overwinter in fallen plant debris, so it is essential to remove this material from the garden. Rake up any fallen hollyhock leaves, stems, and flowers, and dispose of them by early spring. By removing this potential source of infection, you can greatly reduce the likelihood of rust reoccurring in the next growing season.
5. Maintain good garden hygiene: To further control rust and prevent its recurrence, it is important to maintain good garden hygiene. This includes regularly cleaning and disinfecting your gardening tools, especially if they have come in contact with infected plants. Additionally, avoid overcrowding plants and ensure proper air circulation by spacing them adequately.
Personal experience: I have encountered hollyhocks infected with rust in my own garden. Initially, I didn’t take immediate action, and the disease quickly spread to neighboring plants. However, after researching and implementing the steps mentioned above, I was able to effectively control the rust and prevent further damage to my hollyhocks and other plants.
If you notice rust on your hollyhocks, it is important to take action promptly. Pick and destroy infected leaves at the first sign of rust, and cut down and destroy infected stalks after blooming. Additionally, remove fallen plant debris to prevent the overwintering of rust spores. By following these steps and maintaining good garden hygiene, you can effectively control rust and protect your hollyhocks from further damage.
