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.
Raspberries enjoy strong growth in soils heavy in organic matter. Mixing compost or manure into the soil prior to planting improves the drainage of the soil and increases the roots' access to oxygen. Raspberries grow best on soil shaped into raised beds measuring roughly 2 feet in width with a height of 8 to 10 inches.aspberries enjoy strong growth in soils heavy in organic matter.
