I have a huge white oak that is doing worse every year. I was told some years ago that if it does not get deep root feeding every year it will die. I cannot afford to pay a company to do this. My friend told me I should make holes along the drip line and do it myself with fertilizer. I have a pick I can drive good sizr holes every so many feet and pour fertilizer in. Can anybody help me in what type of bag fertilizer to use and how far apart to do this. The canopy is ungodly big. Biggest oak I have ever seen it would be a shame to lose it. It was so thick 30years ago that no ight could get through now it is suffering and the canopy has holes all over you can see through. Please help. Thanks Dave
