Support a leaf from underneath with one hand to prevent tearing.
Wipe the upper surface gently with a damp, soft cloth.
Rinse the cloth in clean, lukewarm water as it collects dust.
Dry any pooling water from the leaf joints to prevent rot.

Scientists discover how plants keep cool during heatwaves
Researchers discovered a molecular mechanism that keeps leaf pores open so water can evaporate and cool the plant. A protein called UBP24 helps control this process when air temperatures rise. This finding can help scientists breed crops that tolerate hotter weather and intense heatwaves.
German botanist and agriculturist Karl Nikolaus Fraas was born on 8 September 1810. He studied medicine and botany before becoming a professor of botany and director of the court garden in Athens. His work helped advance early understanding of plant science and agricultural practices.
