My Yarrow is in full bloom but split open and laid down about 2 week or so ago. Why and what should i do?
This is the second year I've had it. It was fine last year
The yarrow plant tends to flop or fall over, especially if it gets too tall and spindly. You may need to stake such plants as they grow. Bury one end of the stake 1-2 inches away from the base of the plant, then tie the middle of the plant's stem to the stake with string or twine.
