Q.Why Is My New Silver Sheen Getting Dry, Crunchy Leaves And Dying?
Please help! I just planted new 5-gallon silver sheens. Three of them got crispy and died, so I replaced them. Of the new ones, the one that is in full sun every day is starting to get dried, crispy leaves. I’ve been watering them quite a bit since they’ve only been in the ground about 10-14 days (nursery told me the new plants would need a lot of water) and it’s been close to 100 degrees in LA. By quite a bit I mean spraying them with a hose for 30 seconds each (daily) and running a drip irrigation for 30 mins every other day. I’ve been watering the crispy one extra, but it seems like I’m losing 🙁 I added a photo of the new one and the old one. You can post the question/answer to send it to me directly – either works!

This drought tolerant, hardy plant has one kryptonite... Wet soil.
This shrub will appreciate drier conditions, so you should let the soil dry out, thoroughly, down to about 3 or 4 inches between waterings. Likely, unless you are experiencing a drought, you will not need to water at all.
I would treat with a fungicide, and keep the soil more on the dry side. Here are some articles that will help:
