Plants can be prone to various diseases, the first symptoms are recognized by observing the leaves. Therefore it is essential to always keep the leaves of our plants under control. In this regard we will show you how to recognize the plant diseases, following some simple directions.
Plant diseases, prevention
- Remove the fallen leaves at the base of the plants.
- Irrigate the plants taking care to avoid water shortages and excess water: if little weakens the plant making it easy prey for parasites, water stagnation also favors molds and fungal diseases.
- Never leave residues and waste around and always use sterilized tools if possible.
- Inspect plants frequently
- Fertilize without exaggerating, preferring organic fertilization: some parasitic fungi take advantage of the excess nitrogen given to plants.
