Sudden Death? to Pittosporum 'Silver Sheen'
I have (or should say 'had') a beautiful pittosporum'silver sheen' and recently up'd the watering schedule to 8-10 minutes, three times a week during the hot months of summer (it was at 6 min, three times a week and was thriving for 4-5 months). That's when I noticed the leaves getting brown, soft and curly (some leaves are actully crunchy). What went wrong and how much water is needed for this plant for the Carlsbad, CA (San Diego) area?
