Medium_p1030563 I have 6 Pittosporum planted in large planter boxes. They have developed white spots on some of the leaves -

they have also developed brown spots (pictured) and yellowing of the lower leaves at a fast rate, over the last 2 days. In the past few weeks I have also seen on occasion the new leaf tips wilt during the day but they recover by the next morning.

Answer: Hi Fran,
Pittosporum plants are susceptible to both under watering and over watering. If they are over watered they may develop root rot or leaf spot diseases. Are the planter boxes well drained? The very high temperatures in SA recently may cause the Pittosporum to wilt and the lower leaves can brown off and fall. A moisture meter is a simple and inexpensive way to monitor the soil moisture during the hot Summer months.
Apply some Yates Uplift Organic Liquid Fertiliser to help improve the health of the plant. The seaweed will also improve the vigour and health of the roots.
