Pine Tree Fertilizing in Ohio- Suggestions? Advice?

Live around Cental Ohio. Have 6 newer pine trees planted in late October. They have a few orange branches, but I do see some new green budding about to happen. Hopefully that's a good sign. Any suggestions on what to use to help keep these pine trees alive and make them grow FAST. Not sure on the exact type of tree, looks like aChristmas Tree.

Pine Tree Fertilizing in Ohio- Suggestions? Advice?
Don't over fertilize trees, especially pine trees. They are use to low fertile and thin soils. A moderate rate of growth and good, green color is best for most woody plants. Excessive vigor, which is evident by lush, green leaves or needles and long shoot growth is often undesirable. Such trees are more susceptible to freezing injury, are more likely to break during wind/ice storms, are more susceptible to disease and insects than trees exhibiting moderate growth.





Don't fertilize to make a young tree bigger, faster. Think of it as feeding your children more food so they'll reach a mature size faster. It just doesn't happen that way. Overfeeding our children creates obese kids that have troubles now and in later life. The same goes for raising trees.





Fertilize based upon observed growth rate. Here is what Cornell University says: "Determine if it is needed. - Fertilizer is not a "cure-all" and in some cases can be detrimental. Check the trees vigor by measuring annual growth from the terminal bud to the first ring of bud scale scars. If growth on a standard tree is 6" or more, fertilizer would not needed."





If you should decide to fertilize your pine trees, fertilize in late fall when the leaves are dropping but soil temps are still warm. Use a balanced, slow release granular fertilizer.





Occasionally water a pine tree. Supplement the watering in the heat %26amp; drought of summer. Water well just before winter comes. Do not keep the ground wet around pines. Pines generally do not like their feet wet.





Finally, here is some advice from the University of Minnesota Extension Service: "Trees in urban and suburban environments are often under high stress conditions due to low moisture availability, soil compaction, physical damage, nearby construction, and competition from turf and nearby trees and shrubs. Fertilizer applications may reduce, but cannot eliminate, environmental stresses such as these. It is important to keep newly planted trees watered and pruned and to keep weeds away from their bases to avoid excess stress."
Reply:According to Clemson University when fertilizing newly planted trees, use slow- release fertilizers. Care should be taken if quick- release fertilizers are used since roots of young trees are sensitive to over fertilizing. During the second and subsequent years, 2 to 4 pounds of 10-10-10 fertilizer should be applied for every 100 square feet of bed area. For larger trees in open areas, about 2 pounds of 10-10-10 fertilizer can be applied for each inch of trunk diameter of the tree.
