We treated six very stressed mature bur oaks with C20. The trees were in decline with multiple dead branches, foliar chlorosis and wilting leaves. When we examined the trees the following spring, we observed that the trees had stopped dying back and all the new foliage looked vigorous. We now use C20 on many of our sites.

I have seen the dramatic results when using C20 as part of an after-care program for newly planted trees. This product is quickly becoming an integral option when deciding on standards of care for our trees.

Rather than replace declining spruce in a one-year-old planting we used C20 on the trees to be removed. Within one season the trees recovered and saved us the money and headache of buying, removing and replanting!

A game changing new industry standard. (We) will never plant another tree, shrub, or perennial without it again.
