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.
However, for optimal development, plant raspberries in soil with a pH between 5.8 and 6.5. You can adjust the pH of your soil by adding soil amendments, like lime, sulfate or peat moss.hese terms refer to soil texture. Raspberries grow well in well-drained soils. A sandy-loam soil texture is ideal for raspberry growth, as noted by the North Carolina State University Extension. The soil should have a drainage depth of approximately 3 feet and should be able to hold water without becoming waterlogged.
