I love all of these products,ca.oakworm defoliated these 300 year old trees they were pitifully stressed. used the arborcare as directed. within 2wks new growth. one month completely foliated, lush,vigorous and healthy.I know this says season long,but even after 2 years these 2 oaks are still greener than all the other trees on the hillside.you can spoon feed it out of a 5 gallon bucket. user friendly my choice of fertilizer from now on. great product
