Why Is My New Silver Sheen Getting Dry, Crunchy Leaves And Dying?

Question

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 each one with a hose for 30 seconds (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 🙁

Answer 1

You don't need to spray the leaves of the plant. Plants do better with deep, regular watering than frequent, light watering. Make sure the 30 minutes on the drip irrigation is long enough to water deeply and not just surface-wet the area.

I would treat with a fungicide, and let the soil dry out between waterings. Here are some articles that will help: https://www.gardeningknowhow.com/ornamental/shrubs/pittosporum/growing-japanese-pittosporum.htm https://www.gardeningknowhow.com/garden-how-to/info/using-fungicides-in-garden.htm
