Maple Tree's Answer · Hi Gary- The contorted filbert when planted in the ground rarely requires fertilization. Generally, as long as the tree appears healthy with nice foliage, fertilizing is unnecessary. If you feel the tree needs some fertilization you can use a well ballanced slow release fertilizer formulated for shrubs and trees or a quality organic fertilizer such as Plant-tone, Holly-tone or other organic found at your quality nursery or garden center. Fertilizing once in the spring when you notice new growth appearing should be enough yearly fertilization. If the trees are younger I would probably make the fertilizer application at 1/2 strength around the entire trees drip line. Be sure to apply all fertilizers as noted on the product containers and water in thoroughly .
Please ask if you have any other questions.
