From Ground: First, water the gray chickweed to dampen the soil, making it easier to remove the plant. Use a trowel to dig a circle around the plant, giving a generous berth to avoid harming the roots. Gently lift the plant from the ground, preserving as much of the root ball as possible.
From Pot: Begin by watering the gray chickweed to moisten the soil. Invert the pot and gently tap the bottom to loosen the plant. Hold the plant by the base and ease it out, supporting the root ball to prevent it from crumbling.
From Seedling Tray: Water the seedlings beforehand to ensure the soil is moist. Use a spoon or a small stick to carefully lever the gray chickweed seedling out of its cell, trying to keep the root ball intact.
