Tree fertilization

In the period 5/16/2011 to 5/30/2011, we applied fertilizer as follows:

• Dr. Earth Organic 9™ Fruit Tree Fertilizer 7-4-2. We followed the instructiond and applied roughly one cup per inch of tree trunk diameter. We removed the mulch, watered under the canopy, and sprinkled the fertilizer on the soil. This was done to the following trees:
• orange and tangerine tree in left-hand side of our backyard
• tangerine tree by the house
• two fig trees in left-hand side of our backyard
• two small peach trees in the left-hand side of our backyard and large peach tree in the right-hand side
• avocado tree
• Greenall F.S.T. (Iron and Sulfur). The instructions advise to give 1 pound per inch of tree trunk diameter, but we gave them a little less. The F.S.T. was sprinkled under the canopy. This was only done to the following trees:
• orange and tangerine tree in left-hand side of our backyard
• tangerine tree by the house
• Seewead-based foliar fertilizer [brand name and details to follows]. 
  
  We made 1 gallon of fertilizer and mostly spayed it in the leaves. A little left-over was poored into the pots. This was done to the 4 citrus tree that are growing in pots.
