Causes of Scale Infestation

Ever wondered why your beloved houseplants are suddenly covered in scale? Let’s dive into the common culprits.

  • Overwatering and poor drainage: Just like you wouldn’t want to sit in a wet diaper all day (weird analogy, but stick with me), plants don’t like having wet feet. Overwatering creates a perfect environment for scale and other pests. So, maybe ease up on the watering can, yeah?
  • Lack of natural predators indoors: In the great outdoors, ladybugs and other predators keep scale in check. But indoors? It’s a scale free-for-all. Without these natural checks and balances, scale can run rampant.
  • Introducing infested plants to your collection: We’ve all been there. You see a gorgeous plant at the store, and you just have to have it. But if you’re not careful, you might be bringing home more than just a plant. Always inspect new additions for signs of pests.

Early Detection and Prevention

Prevention is better than cure, especially when it comes to scale. Here’s how to stay one step ahead of these pesky pests.

  • Regularly inspecting your plants: Make it a habit to give your plants a once-over every week. Look under the leaves, along the stems, and in any nooks and crannies. The earlier you spot scale, the easier they are to deal with.
  • Quarantining new plants: Before introducing a new plant to your collection, keep it in a separate space for a couple of weeks. This gives you time to ensure it’s not harboring any unwanted guests.
  • Maintaining optimal humidity and temperature: Scale thrives in certain conditions. By keeping the humidity and temperature in check, you can make your home less inviting to these pests.
