What is white rust and why does it happen?
White rust is caused by fungal-like pathogens that spread rapidly when the environment is consistently moist. Unlike pests, this disease develops quietly and is often only noticed once the white patches appear underneath the leaves.
Common causes include:
- Excessive watering or poor drainage
- Prolonged rainy or humid weather
- Overcrowded planting with poor ventilation
- Water sitting on leaves for long periods
Because the fungus grows on the underside of leaves, it is often overlooked until the infection becomes more severe.
How to treat white rust naturally?
White rust on your plants can be treated naturally, using eco-friendly methods that help eliminate the fungus and restore your plant’s health without the need for harsh chemicals.
1. Prune infected leaves
Trim off all leaves with visible fungal patches.
- Retain at least 70% of healthy foliage to avoid stressing the plant
- Always disinfect pruning scissors before and after use
This step helps stop the spread of fungal spores immediately.
2. Apply organic plant acid spray
After pruning, spray Mr Ganick Organic Plant Acid on:
- Both sides of leaves
- The tree trunk or main stem
This helps suppress fungal growth and supports the plant’s natural recovery process.
3. Improve air circulation
Avoid planting too densely.
- Leave about 20% spacing between plants
- Ensure good airflow, especially in humid or rainy seasons
Proper ventilation helps keep leaf surfaces dry and discourages fungal growth.
How to use Mr Ganick Organic Plant Acid effectively?
To maximise results, follow these application tips carefully:
- Shake the bottle well before use
- Spray in the morning, avoid spraying under direct sunlight
- Apply evenly on leaves and trunk
- Frequency: For preventive or mild cases, consider spraying once a week. For severe conditions, every 3 days until symptoms improve.
Consistency is key for fungal control.
