I make balls from Hollytone and I spray the foliage every week with miracle grow. I had one that was week in the spring and its getting big sharp buds now.
Similarly, I use cakes made with Plant Tone and feed weekly with fish + kelp...on all my trees, including the collected ponderosa pines...March-November.
I learned from Warren Hill this weekend at the Midwest show that Miracle gro has a lot of salt in it and he highly recommended not using it and only using organic fertilizers.
l also spoke with Andy Smith of Golden Arrow and he uses organics on his collected ponderosa pines.
