Thoroughly Clean Your Plants Before Bringing Them Inside
Before allowing your houseplants to enter your home, inspect them closely.
'Check the leaves, stems, and soil for any signs of insects, eggs, or other unwanted guests,' advises Sally Allsop, founder of All That Grows. 'Be especially vigilant with the undersides of leaves, as pests often hide there,' she adds.
Pests can vary in appearance, from tiny spider mites to white mealybugs. If you see any insects on your plants, it may indicate a pest problem.
'Treat the affected plant appropriately before bringing it indoors,' Sally stresses. Whether you're removing spider mites or dealing with aphids, ensure all pests are managed before they spread to other plants. Various pest control solutions are available online, including this houseplant insect killer from Amazon.
'It's also wise to clean your plants thoroughly. Gently wipe the leaves with a damp cloth,' Sally suggests. 'You can lightly scrape the soil to expose and remove any hidden pests,' she continues.
Cleaning plant leaves is simple with a soft cloth, such as these microfibre cloths from Amazon. Misting the leaves can also help keep them clean, like this plant mister from Amazon.
Sally is a passionate gardener and founder of an online gardening platform, sharing her extensive knowledge of plant care with others.
Quarantine Your Plants to Prevent Pest Spread
When you bring your plants inside, isolate them from other houseplants for 3-4 weeks, advises Vladan. 'This allows you to monitor for any potential pest outbreaks,' he continues.
Address pest issues promptly to keep them from affecting your other plants. Consider placing the newly brought-in houseplant in a conservatory or on a windowsill away from your other greenery to quarantine it effectively.
