I have a potted pittosporum which was healthy until I recently moved it from the patio to shade because of the very hot sun and it has quickly started dropping all the leaves and dying. Should I move it back into the light, plant it or accept I have ruined what was a good healthy plant? Needless to say I am not the worlds greatest gardener :-)
Pittosporum can drop leaves at times; especially during times of stress. Try morning sun and afternoon shade. Keep the container moist but never soggy or dried out completely.
Soggy roots can cause root rot quickly with Pittosporum.
Hello, I bought 2 pitt plants a year ago, and 2 more just recently. They were all labeled puttisporum silver sheen. However, once in the garden, the two sets look different. The new ones are very young, though, so I am wondering if maybe they are the same type, but need time to grow to look similar... Here are 2 photos of the first (older plants) purchase, and 2 of the second purchase (young plants). Can you tell me if these are the same types of plants, or different types? I am growing a hedge, so I want them to match and grow to the same height... Thank you
Pictures loaded wrong...T clarify-photo 1 shows both old and new plant side by side (new plant is smaller one on left). Photo 2 shows new plant leaves closer up. Photo 3 shows old plant leaves close up.
I live in Sydney Australia and planted several pittosporum trees about 20 years ago. They are mostly healthy even though we are having a hot summer. I keep them watered and give them a slow release pellet feed twice yearly. I have noticed that they all have marks on the trunks with a pale coloured sap leaking from them, but not all the way down the trunks. Is this a sign of a pest or nothing to be concerned about? Thanks. Sandra
Though I am not completely familiar with the pests in your area, I would be likely to say that it could be an animal that is damaging them. If possible try and enclose the area in fencing, or even wrap the trunks very lightly individually.
Here is an article for more information on the plant: https://www.gardeningknowhow.com/ornamental/shrubs/pittosporum/growing-japanese-pittosporum.htm
I’ve got two Pittosporum Garnetti’s. One has just been planted but the leaves are going yellow and dropping off, it’s in a large pot 21”square. The other one which is 5ft tall and cost an arm and a leg, was planted last year, the leaves are browny/red on the outside and the overall appearance is darker. However, it has got new growth on its tips. When I plant new plants I always use a good tree and shrub compost with Vitax Q4 and Michorrizal Root Powder and water well.
Make sure that you cut this compost with potting soil, or it could be way too "hot" for the shrub. This would explain the burning, or dropping of leaves.
The next concern would be how much drainage the container has, and how much water was used. This could also be symptoms of a fungal infection, which can happen when soil remains saturated for too long, or sits in excess water.
I also recommend dolomitic lime added to the soil to keep the pH stable. Wettable sulfur will kill off any harmful microbes, as well as keep the soil conditioned to prevent bad infections.
We have sprayed them with Neem oil but so far the leaves and branches are still slowly turning brown. What else should we do?
It is impossible to dianose and make recommendations without knowing more about the growing conditions and your soil and water management. Neem oil is not a cure-all and in some cases it is not appropriate treatment. Wrong dilution rate can cause burning of foliage.
Look first to water management, too much or too little? Too little is most common in cases of decline and die-back. If the plants have adequate irrigation, then consider fertilization and mulch. There are insect pests to consider.

I have three 4 year old pittosporum trees. They were growing well and bushy until I discovered sooty mould on them and they had black scale. Ive since treated them with white oil which seems to have fixed the issue but the trees have now lost a lot of their leaves lower down and are sparce. My Q is will they generate regrowth and bush up with new leaves again? Should i prune them which will make them even sparcer or will this help? See photos.
Was this actual mineral oil, or was this a home meade soap oil? Actual white oil will not cause these symptoms, but soap can if it is not diluted enough.
Another issue could be that an insect is not to blame for the damage. Fungal issues are very common and can look like scale sometimes. Insecticides will not be effective against infections of this nature.
Can you include a photo? This will help me to see what is going on, exactly. Then I can recommend the best remedy from that point.
