What’s the problem?
I’ve heard “plant hygiene” mentioned, but I’ve no idea what it actually means.
Diagnosis
Good plant hygiene is the gardening equivalent of washing your hands – simple, essential, yet often overlooked. Neglecting plant hygiene can lead to the spread of pests, diseases and infections. Using dirty scissors, pots or tools can transfer fungi, bacteria or pests from one plant to another. Similarly, letting dust build up on leaves can restrict photosynthesis.
Prescription
Sterilise secateurs, gardening scissors and tools with alcohol or diluted household disinfectant before use. Wipe the blades before putting them away, particularly after pruning diseased leaves or stems. Reusing pots is great, but remember to scrub away old soil that might harbour pathogens. Gently clean your plants’ leaves with a damp cloth to remove dust.
Prevention
Check plants weekly for signs of pests or disease. Maintaining cleanliness by wiping leaves, removing debris and sterilising pots and trays will reduce the risk of disease and allow your plants to flourish.
