Newly planted trees are not the only ones needing spring care. By continuing the care given to your seedlings you will insure the future health and vigor of your trees. Established trees, unlike seedlings, usually benefit from fertilization after two growing seasons or more. A general rule of thumb is to use one ounce of all purpose fertilizer for every foot of tree height. Apply the fertilizer in the early spring as soon as the soil is frost-free.
Roots begin growing and absorbing nutrients long before the trees leaves unfold.
Annually monitoring older trees for insect, disease, pollution, or pesticide damage, can greatly reduce the damage to your trees. Use pesticides carefully and only when symptoms have been identified as a specific insect or disease problem that should be controlled chemically. Beware of weed and feed lawn care products that can contain herbicides that are deadly to your trees and shrubs. Trees planted close to agricultural areas are especially vulnerable to pesticide drift. Right CIS No.
