If tree growth is poor or the leaves are pale, it's time to fertilize. If leaves are normal size and color, there's no need to feed. When you do decide to feed, use an 8-8-8 or similar fertilizer and broadcast it beneath the canopy of the tree no more than once a year. If you overfeed trees they will put out rank growth that will be weak and susceptible to wind damage. I'd prune the dead branches off the oak tree and rub out any sprouts that emerge along the trunk. If you rub them off they won't leave a scar. If you allow the sprouts to grow into branches, you'll leave a scar when you prune them off. Hope this clarifies things for your. Best wishes with your trees.
