I'm here to help you out with your Pieris tree. I know it's tough when the leaves start to turn brown, but there are some simple tricks to bring those leaves back to life. First, let's talk about pruning. If your leaves are brown, it might be because they're not getting enough sunlight. Try moving them to a brighter spot in your home or outside, and see if that helps. If they're still looking a bit dull, it might be because the soil isn't getting enough moisture. Make sure you're watering them regularly and checking the drainage. If you notice your humidity levels are a bit low, don't worry! There are ways to help with that, too.
