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.
One of the things to remember when thinking about how to grow raspberries is that you should not plant them within 300 feet of any wild blackberry bushes. You should also stay away from ground that has had tomatoes or potatoes growing in it within the past year or so.fter that, you can fertilize your growing raspberry bushes annually. You will use two to three pounds of 10-10-10 fertilizer per 100 foot of row. Scale that down if you are only planting a couple of bushes. You will also need to prune raspberries as part of their care.
