Lady Palms turning yellow and not growing
I planted 4 lady palms in my yard last November (I live in Berkeley, CA) and though they started off green, the leaves have now turned quite yellow. The plant doesn't look like it's dying, just yellowing. I have it watered with my drip irrigation and each gets about a half gallon a week. I also give it a little Miracle Gro Shake n Feed for Palms 3 times a year.
Also, I was hoping that the palms will grow taller than my fence and become a bit of a screen but it doesn't seem to have grown at all. Is there something I am doing that is stunting it's growth?
I've tried reading up on the net but not getting much. Hoping someone here can help.
