1 (e.g. I > Cl > C > H)  If the first atom of two groups is the same, consider the second atom(s) in the same way as the first. (e.g. -C(CH3)3 > -CH(CH3)2 > -CH2CH3 > -CH3). If this does not assign priority, consider the next atoms until there is a difference.
Fertilize blackberry bushes in the early spring just as they begin to put forth new growth. Use 1 pound of 20-20-20 granular fertilizer for every 25 feet of row, broadcasting it evenly around the base of your shrubs. If you use 10-10-10 fertilizer, apply 2 pounds for every 25 feet of row. Feed blackberry bushes again when they are blooming in midsummer. Do this only if your bushes are not thriving. Apply 1/4 pound of a 34-0-0 fertilizer, also called ammonium nitrate, for every 25 feet of row.
Fertilize. Lack of regular feeding is one of the reasons an African violet will not bloom. The best way to feed is to use a dilute fertilizer solution every time you water. Use 1/8 to 1/4 tsp. fertilizer to one gallon of water. A balanced fertilizer should be used such as 20-20-20 or 12-36-14.
