Q.fertilizer for weeping willow tree
What type of root fertilizer should I use to feed my weeping willow tree? The tree in question is 30 ft tall and is around 30-40 yrs old. I don’t know for sure because tree was here when I moved here last year. It has a well established canopy, but is kind of pale looking. Leaves get green but weak looking green. Thanks for the help.

I would go for a balanced fertilizer with an equal ratio of nitrogen (to support foliage growth), phosphorus (to support growth of roots, stems and flowers) and potassium (for overall health), such as a 20-20-20 formula.
