Why Do Leaf Edges Brown First?
Plants take up water through fine bird feeder root . The water system is then transported through the plant ’s vascular system to the plant life ’s leaves , needles , or other leaf .
The water rises through the plants ’ veins and supplies the tissue cheeseparing to the plant ’s central stem or trunk first .
