Titanium and aluminum are often used as colorants in tattoos; more worrisome, inks using nonmetal colorants may include traces of antimony, arsenic, beryllium, chromium, cobalt, lead, nickel, and selenium (AESI filed over the latter eight metals).
Apply about two ounces of a 5-10-5 fertilizer around each plant. Starting the second season and annually thereafter, fertilize raspberries in early spring before growth begins. Apply a balanced fertilizer, such as a 10-10-10, at a rate of 15 to 20 pounds of fertilizer per 1,000 square feet of planting. If using the hill system, apply about one-half cup per plant. Don't fertilize raspberries in late summer or early fall as it may force new growth that does not harden off properly for winter.
How to Fertilize a Tree. You do not need to remove mulch to fertilize! Scatter or drop pellet fertilizer under the tree's drip zone but avoid touching the tree trunk with the material. Do not over-fertilize. An application of between .10 and .20 pounds of nitrogen per 100 sq. ft. will be adequate. Again, read the label. Keep solid or concentrated fertilizer off stems and leaves and adequately water the fertilizer into the soil as that prevents fertilizer burn injury to roots.
