I carried my patio pots straight onto the living room shelf just to beat the first frost: ten days later, under the newest leaves, I understood what had travelled in with them
When frost threatened, one gardener rushed patio pots indoors without inspection—only to discover a thriving aphid colony ten days later. The mistake is more common than gardeners admit, but the prevention is simpler than the cure: a ten-minute inspection routine and proper quarantine can stop hitchhiking pests before they spread through your entire plant collection.
