Royal Gold Crown Jewels Bloom 1-4-2

Royal Gold Crown Jewels Bloom: 1-4-2 With 11% Calcium for Flower and Fruit

Crown Jewels Bloom is a one-part dry fertilizer for the flowering and fruiting stretch, made to go into the soil rather than a reservoir. Royal Gold blends it from rock phosphate, gypsum, alfalfa meal, basalt, kelp meal, neem seed meal, shrimp meal, Epsom salt, sulfate of potash and dolomite. The guaranteed analysis reads 1-4-2, with 11% calcium and 0.5% magnesium. Most of the nitrogen is slow, with 0.7% water-insoluble against 0.3% that plants can take up right away. Phosphorus leads the label because flower sites and fruit set pull hardest on it once the light schedule flips. That calcium figure is the quiet strength of the blend. It feeds cell walls in swelling flowers and fruit, and it replaces what a heavy season pulls out of the root zone. The ingredients are micronized, so a top-dress breaks down evenly instead of sitting in clumps on the surface. This listing is the 20 lb bag, packed two to a case, and it carries an OMRI listing as well as CDFA registration. Royal Gold makes it in Humboldt County alongside its coco soils, and it works in those mixes or in any living soil or soilless blend.

Working a 20 lb Bag of Organic Bloom Fertilizer Through the Season

Start a week ahead of transplant by mixing one to one and a half cups into each cubic foot of soil. Water it in well so the blend settles before roots arrive. In smaller pots that works out to three to four and a half tablespoons per gallon of media. Once plants are established, top-dress half a cup to a cup per cubic foot, scratch it lightly into the surface and water thoroughly. Repeat that every ten to fourteen days through flower. In open beds, Royal Gold calls for ten cups per hundred square feet before planting, then five to ten cups every four weeks. A cup weighs roughly half a pound, so this bag holds about forty cups. That is enough to pre-amend twenty-six to forty cubic feet of soil, or to prep around four hundred square feet of bed. For aerated tea, brew a cup per ten gallons of non-chlorinated water for up to two days, then apply it full strength or diluted. The bag suits a greenhouse bench, a run of raised beds or a commercial top-dress program where every round uses several pounds. Two cautions are worth knowing before the first round. OMRI lists this blend as Allowed with Restrictions, so certified organic operations need soil or tissue tests documenting the deficiency first. Indoors, expect a strong organic smell for a day or two after each top-dress.

Key Features

• 1-4-2 Bloom Analysis: A phosphorus-forward feed supports flower set and fruit fill without pushing late nitrogen.
• 11% Calcium: A heavy calcium charge supports cell walls in swelling flowers and fruit through the final weeks.
• Slow Nitrogen Release: Most of the nitrogen is water-insoluble, so it feeds gradually instead of spiking after each application.
• Micronized Ingredients: Fine particles spread evenly as a top-dress and break down at a steady pace in the root zone.
• OMRI Listed and CDFA Registered: The blend is cleared for organic crop production, with OMRI restrictions tied to documented deficiencies.
• Soil, Top-Dress or Tea: One bag covers pre-plant amending, in-season top-dressing and actively aerated bloom teas.
• Works in Any Living Soil: It blends into Royal Gold mediums, native soil and quality soilless mixes without a change in routine.
