Grey mould


This disease is common among various soft fruits such as strawberries and raspberries as well as in many ornamental flowers.

It often develops when plants are grown in humid conditions, so avoid overcrowding your shrubs and make sure to ventilate them well when grown under glass.

Leaves of box plants turn brown and fall off, and the leaves on its young stems dieback due to this fungal disease.

The affected fruits can either fall or hang mouldy from the tree. Remove these fruits as soon as possible to stop brown rot from spreading.



This disease, which is prevalent in potato and tomato plants, can destroy an entire crop, or make them fully inedible. It is common in warm and moist conditions, causing leaves to turn brown from the edges inwards and stems to crumple and die.
