The ones spreading out are established. They're about 7 years old.
I saw the Hollytone and the Miracle-Gro at the nursery this weekend. So I just use 1/2 a packet of the MG diluted in a 5 gallon bucket. I'll pick some up this week. I did go around the yard last night and spray MG on the beds including shrubs. It won't hurt to douse the bushes again in a few days?
It's odd...I have one near a gardenia that's just beautiful. Thick and full and gets hit with a LOT of afternoon sun. The ones in the front that aren't doing so well get a bit of shade in the afternoon.
Hopefully, the combo of Hollytone and MG will do the trick. Thanks again!
