Buying Guide: Key Purchase Considerations
What should you consider when choosing an anti-transpirant spray?
- For evergreens and large landscape plants, concentrate formulations often offer longer protection per application. For houseplants and seedlings, ready-to-use sprays are typically more convenient.
- In winter, choose products marketed for winter protection. In hot, dry seasons, drought-focused formulas help conserve water.
- Sprays that dry to a clear film generally allow light and gas exchange to continue, which supports photosynthesis and respiration.
- Some products last weeks; others require more frequent application during extreme conditions. Always follow label directions.
- Some species may react to spray films. Test on a small area before broad use on delicate plants.
