Certified ExpertA.Maybe nutrient deficiency. But it looks like a possible virus. There is a mosaic virus that goes to pittosporum.
There is no definitive cure for most viral diseases in plants, but they are not necessarily killers. Keep the plant as healthy as possible with good soil and water management.
Applying a complete, mineralized, organic fertilizer that has balanced macro and micronutrients would address the possible nutrient deficiency. It would also support the plant health in case it is a virus. This is the best fertilizer I know of, short of getting soil analysis and an Rx for amendments.

94041Q.Why Is Part Of My Pittosporum Tenuifolium Tree Dying. Some Branches Are Healthy, While Others Are Dying
Overall the tree appears healthy, gets full sun and good drainage. Located in northern California, just south of San Francisco. Trunk looks ok. Branches seemed to develop cracks and dye over a long period about 6 months. Thanks for the help. These are great trees.

I have about 20 plants and this is only happening to some of them. I tried giving some acidic iron, manganese and nitrogen to one but didn’t seem to help.

Certified ExpertA.Unfortunately, your photos did not come through. I am unable to see the damage. Most commonly, this will be overwatering. Just be sure that your soil is lacking in the amendments that you are adding before adding them, as this can throw off the soil balance.

June 3, 2020A.Hi, thanks so much for your help. Please let me know how I can send you pictures. The pittosporum are actually my neighbors’ plants. He waters twice a week but not for long. I think he should water once a week for a longer time. I still think that there may also be a fungus and/or nutrient issue. Thank you!

San Francisco CAlifornia USA 94118Q.Pittosporum – Yellowing And Brown Spots
Not sure if this is a watering, nutrient or fungus issue, or some combination. Some plants are green, others have yellow leaves, some yellow leaves have brown spots and some green leaves have brown spots. My neighbor waters them twice weekly for short period of time. I think a longer, once weekly watering would be better, maybe some iron and magnesium, and maybe some copper fungus spray? (Organic non-toxic solutions only please.) Thank you!

Certified ExpertA.This appears to be Alternaria spotting. This needs to be treated with a fungicide containing copper.
I would only water when the soil is completely dry down to about 2 or 3 inches rather than on schedule, and keep all infected and dead debris completely away from the area. Make sure to water the soil directly, and not the plants foliage, when possible.

Certified ExpertA.This can be normal for transplant shock. This will be exacerbated by disturbing the roots while transplanting.
Care will include making sure that the water level is perfect. Too dry and leaf loss can occur. Too wet, and you will be met with the same symptoms, and possibly black or brown spotting.
As long as you wait until the ground is completely dry down to about 3 or 4 inches between watering and care for it as it should, then it will come out of shock within a few weeks.
Here are a couple of articles that will help:

Certified ExpertA.I would wait until they recover to transplant, but only transplant if the health of the shrub is at risk where it is, now.
These shrubs enjoy a good hard pruning, as this can restore their health and shape.
