Collar: The area where the stem of a plant meets the root system, often a vulnerable point for diseases and pests.
The collar of a plant is a critical zone, like a bridge between the above-ground stem and the underground roots. It’s where the plant’s vascular system transitions, and it’s often a susceptible area. Think of it as the plant’s “neck”–if it gets damaged, the whole plant can suffer.
In a home garden, the collar is important to consider when planting and caring for your plants. Planting too deeply can bury the collar, making it prone to rot. Keeping the area around the collar free of weeds and debris helps prevent pests and diseases. Some pests, like cutworms, specifically target the collar area. So, paying attention to the collar is key to keeping your garden plants healthy and strong.
