Royal Gold Crown Jewels Bloom 1-4-2 in a 5 lb Bag for Pots and Patio Beds
Calcium is the number to notice on this label, at 11% alongside a 1-4-2 analysis and 0.5% magnesium. Crown Jewels Bloom is Royal Gold's one-part dry feed for anything that flowers or sets fruit. That covers tomatoes and peppers in pots as readily as roses, hibiscus and flowering shrubs. The phosphorus comes from rock phosphate, and gypsum and dolomite supply most of the calcium. Epsom salt adds the magnesium, while kelp meal, alfalfa meal, neem seed meal, shrimp meal, basalt and sulfate of potash fill in the rest. Only 0.3% of the nitrogen is water-soluble, and the remaining 0.7% releases slowly as soil life breaks it down. That low, slow nitrogen keeps flowering plants from flipping back into leafy growth. The blend is micronized, so it sprinkles evenly across the top of a pot without clumping. This bag weighs 5 lb, ships eight to a case, and carries OMRI and CDFA organic credentials. It is mixed in Humboldt County, California.
Using This Fertilizer for Flowering Plants in Containers and Small Beds
Most of this bag will go to work on a patio, a sunny windowsill or a short row of raised beds. For new pots, blend three to four and a half tablespoons into each gallon of potting soil a week before planting. Once buds start forming, sprinkle one to three tablespoons per gallon of soil across the surface, scratch it in and water. Repeat every ten to fourteen days while the plant keeps flowering. A one-gallon houseplant topped up at two tablespoons per round gets roughly eighty feedings from this bag. Gardeners who prefer the watering can can stir up to half a tablespoon into each gallon of water and pour it at the base. An aerated brew at a cup per ten gallons works for anyone who already runs a tea setup. For young or tender plants, start at the low end of each rate and work up from there. Fresh top-dressing smells earthy for a day or two, which matters more for indoor plants than for a deck. The honest limit sits with certified organic farms. OMRI lists the blend as Allowed with Restrictions, so those operations need a documented deficiency before using it.
Key Features
- 11% Calcium Charge: Calcium supports strong cell walls in blooms and fruit, which helps flowering plants carry a heavy set.
- 1-4-2 Bloom Ratio: Phosphorus leads the analysis for flower and fruit production without a late nitrogen push.
- Container Friendly: Tablespoon-per-gallon rates make it easy to dose single pots, hanging baskets and window boxes.
- Watering-Can Tea: Up to half a tablespoon per gallon of water gives a quick liquid feed at the base of each plant.
- Slow-Release Nitrogen: Most of the nitrogen is water-insoluble, so feeding stays steady between applications.
- OMRI Listed and CDFA Registered: Organic credentials suit home gardens, with OMRI restrictions noted for certified farms.
