Quarantining New Houseplants: Spray Thoroughly, Monitor Regularly

Will Creed: Pest spread is often exaggerated. Pests can exist undetectably for years, explode under stress. Isolation doesn't guarantee safety. Better: spray new plant thoroughly until dripping (covers existing pests). Most importantly, inspect all plants regularly—check leaf undersides for mites, nooks for mealybugs. Early detection + fixing underlying stress (light/water) is key.
