FERTILIZING FOR THE FANATICAL ROSARIAN
by Gail Trimble, Master Rosarian
Before fertilizing, be sure to WATER the night before.
LIQUID FERTILIZING BY GARBAGE CAN
Use a 33-35 gallon size can
2 Cups Miracle Grow, Rapid Grow, K-Mart brand, or Kirkland (Costco's brand) water soluble fertilizer
2 Cups Fish Emulsion or MaxSea
2/3 Cup Chelated Iron (liquid)
2 Cups Epsom Salts (use only twice a year)
10 Cups Alfalfa pellets (use only twice a year)
After putting ingredients in garbage can, add water with nozzle on jet force to top of can.
Apply 1 gallon to each rosebush, 1/4 gallon to each miniature.
If you want to make an alfalfa "tea", put 10 cups alfalfa pellets in garbage can, fill with water and let "seep" 3-4 days. You may need to cover the can to keep in the stench. On the day of applying to the rose plants, add the remaining ingredients, mixing well.
1 cup Superphosphate or Bone Meal
1 cup Blood Meal or Hoof & Horn Meal
1/2 cup Osmocote or other timed release fertilizer
2 cups Ironite
2-3 cups Mushroom Compost
2-3 cups Chicken Manure
1 cup gypsum (once yearly)
2 oz. Ortho Systemic Rose Food (once yearly)
1-2 cups Alfalfa pellets (twice a year only)
3 oz Epsom Salts (twice a year only)
Mix ingredients in bucket and apply to each rose bush. For miniatures, divide bucket contents among 5-6 minis. Turn ground over with trowel and water well.
