QuestionOur ponderosa pine trees in northern Calif. have produced the largest number of pine cones this spring than ever in my 58 years of living here. What could cause such an unusual event? The cones appear normal, just incredibly numerous.
AnswerUsually pines will produce large numbers of cones if the tree is under stress. I would fertilize the tree with 10-10-10 fertilizer at the rate of 1 lb per inch of trunk diameter scattered around the tree and watered in good. This will increase the overall health of the tree.
