20 year old oak tree not healthy #130274

Asked May 28, 2013, 12:45 PM EDT

For the last two or three years my (20 year old) swamp oak tree has only produced 50% of leaves - color of leaves have not been as green/lite color / maybe yellowish -  I have tried to put air holes in ground - added iron in the ground - drilled holes in tree to feed it that way - no use - only 30% of tree has leaves and it does not look healthy - lot's of limbs have no leave buds and when they do have some they break off very easy.  HELP if you can - Joe
