Spider Mites
Tiny webs, stippled leaves. One of the most common — and destructive — houseplant pests.
Shop solutionsThrips
Silver streaks and distorted new growth. Thrips are fast-moving and hard to eliminate with chemicals alone.
Shop solutionsAphids
Soft-bodied and colony-forming. They drain plant sap fast and spread to neighboring plants quickly.
Shop solutionsFungus Gnats
The larvae are the real problem — they feed on roots in the soil while you're busy swatting the adults.
Shop solutionsMealybugs
White cottony clusters in leaf joints. Stubborn, sticky, and a nightmare for collectors.
Shop solutionsRoot Rot
Yellowing leaves, mushy stems, collapsing plants. Often caused by overwatering but treatable biologically.

What Is an Aroid?
Aroids evolved to solve the hardest problem in the rainforest—how to live with too little light and too much competition. The result? Some of the most beautiful plants on Earth.
How to Keep Variegated Leaves Through Winter
Winter light can turn your prized variegated leaves solid green. It isn’t bad care—it’s survival. Learn why plants shift their patterns when days get shorter, and how steady light and warmth can help keep the white in your Monstera or Philodendron from fading away.
Can Plants Hear Touch?
Plants don’t have ears, but they aren’t deaf to their surroundings. From sensing a fingertip brush to detecting the vibrations of chewing insects, plants register touch and sound through finely tuned cellular systems — and even change how they grow in response.
