Hello! I'm not too experienced of a gardener so I'm having a bit of a problem with my milkweed and yarrow. The leaves on my milkweed are very droopy even though I've been watering. It used to be that I'd water it every time the leaves are droopy and they'd perk back up but now they're permanently droopy no matter how much I water it. I've had my yarrow for a shorter amount of time but in just 2 days after purchasing the plant started drooping. I water my yarrow the same amount I water my milkweed. Any ideas?
