Hello
So I planted these ficus in 2017. You will see a photo of them in 2020. I cant figure out the problem as to why they are not FILLING up. I used to water with sprinklers and recently changed them to a drip irrigation that has holes every 12" and there is two lines ... one in front of tree and one in the back.

I am in Burbank which is in California and Valley so summer its usually 90-100 degrees.

I water 30 minutes at 7am DAILY. I recently noticed my leaves turning LIGHT GREEN so I changed it to every 2 days instead.

Today I walked up to the plant and noticed black curled leaves. I opened it and noticed white and black insects inside.

1) Can someone please tell me what is causing these leaves to curl, turn black and insects lay eggs inside?
2) Why are my hedges not FILLING up. I have my gardener TOP OFF the hedge so it grows in width, but its not.
3) My gardener fertilizers it 2x a year, 15/15/15 is what he uses.

Any recommendations is appreciated !!!!!!! Thank you

Oh no. Laurel-Fig Thrips (Gynaikothrips ficorum). A bad thrip infestation is hard to treat, but there are a lot of options to try. Read up at the UC-IPM website:

I will say that I think you are still watering too frequently. Try watering deeply once a week or even less often .
