These are a couple of dwarf pittosporums planted about a month ago. I water every morning for an hour (drip). These two (out of 6) in the area are growing like this and Im not sure what to do about it. I have already checked underneath in the soil- plenty of moisture.

Weird also is that the area these shrubs are planted (full sunlight from dawn to about 3pm) about 6 feet away from a 5yr old oak (the excess water from the shrubs drains down from the house, where the plants are, towards the street, passing by the oak). His leaves are starting to brown as well.
All other plants (hollys, indian hawthorns) surrounding are doing fine (except for the flowers who continue to get eaten by birds).

It looks like a fungal disease to me. Personally, I don't believe tht they need to be watered daily, which may be part of the problem. The soil can dry a little between waterings. You may want to spray with Garrett Juice and a strained cornmeal mixture.

heres what the oak tree looks like.

An established tree does not need that much water. I hope others jump in with thoughts but I have a red oak that's been in the ground 2 years and it gets watered maybe once or twice a week at the most.

i dont water the tree daily, just the new shrubs.
I got the garrett juice stuff and giving it a try. But ill also never go back to the plant shed again.

2 more plants are now dying. But I noticed underneath on of them was a small mound of ants. Does anyone know if the ants there is a good or bad thing... and maybe killing the plants

when you pull up the dying plants, how wet is the soil? I don't believe a small mound of ants can do that harm. I work in a greenhouse and nursery and we ants in pots all the time w/out problems.

That sounds like a heck of a lot of watering to me!

Its damp enough. The plants are gettng plenty of water. Garrett juice was a waste of money. So the only other option now is to stop watering for a while.
