Answer
Fall fertilizers are not high in nitrogen. Historically, the use of 0-10-10 or Alfalfa meal has been recommended to provide a boost to plant's immune system to combat the ravages of coming cold weather and subsequent fungal diseases. The best practice after this is mulching or top dressing with a manure or Forest Mulch Plus (the Plus is chicken doo). Do not apply a mulch to fruit trees as this will hold excess moisture in the ground around the tree which is harmful. Don't feed plants over the winter as this encourages new growth that can be killed by frosts. The only exception would be annual flowers such as primrose, pansies and cyclamen which are actively growing in winter.
