Preventative Measures for Healthy New Guinea Impatiens
Taking proactive steps to prevent diseases can save time, money, and effort in the long run. Here are some essential preventative measures:
1. Choosing Healthy Plants, New Guinea Impatiens Diseases Pictures
When purchasing New Guinea Impatiens, choose healthy specimens without visible signs of disease. Inspect the foliage, stems, and roots for any abnormalities.

Regularly deadhead spent blooms and remove any wilted or infected leaves. This practice promotes new growth and helps prevent the spread of disease.
5. Soil Health
Using well-draining soil enriched with organic matter can promote healthy root systems. Testing soil pH and nutrient levels will help in maintaining optimal conditions for your plants.
