The 5-5-5 NPK (5% nitrogen, 5% phosphorus, 5% potassium) formula in these large plant food spikes was developed to meet the unique requirements of evergreens, pines and other coniferous trees and shrubs. Spikes fertilize below ground where plants need it most for lush needles and leaves, and bountiful seeds and cones. For best results, apply plant food spikes in the spring when plants use a lot of energy producing leaves, cones, and seeds; and in the fall when they're storing energy for winter. Easy-to-use large plant food spikes will not break, crush or smash; just hammer them in, no cap or special tools required. Large plant food spikes are pre-measured so you'll be less likely to over-fertilizer you plants; and there's less likelihood of nutrient loss or leakage into local waterways and ecosystems.
