SUPERthrive Bloom Plant Nutrients 3-12-6 | 1gal - (Case of 4)

Pre-Bud Phosphorus Concentrate to Kick-Start Flowering, 1gal

Many all-purpose fertilizers carry roughly equal nitrogen and phosphorus, which works fine for foliage growth but doesn't give flowering plants the phosphorus push they need right as buds are about to form. SUPERthrive Bloom Plant Nutrients 3-12-6 shifts that ratio deliberately low in nitrogen and high in phosphorus, and its balanced mix of ammoniacal and nitrate nitrogen is formulated to help keep stems compact instead of stretching out as the plant shifts into flowering.

The 1gal size, sold as a case of 4, gives a regular indoor or container grower enough concentrate to carry a full flowering cycle across multiple plants without running out mid-bloom.

Key Features & Benefits

• NPK 3-12-6 formula — low nitrogen and high phosphorus content weighted toward bud and flower development rather than leaf growth.
• Balanced ammoniacal-to-nitrate nitrogen — formulated to help keep stems compact instead of stretching out during flowering.
• Pre-bud application timing — applied just before flower buds appear to help trigger the shift into flowering.
• Broad flowering-plant use — suited to roses, orchids, African violets, and most other flowering ornamentals.
• Concentrated liquid form — mixes into an existing watering routine rather than requiring a separate feeding system.

Who Should Use SUPERthrive Bloom Plant Nutrients

This concentrate fits home gardeners and commercial growers of ornamental flowering plants, roses, orchids, and African violets who want a dedicated phosphorus push right before buds set, rather than relying on an all-purpose feed through the whole cycle.

About Dyna-Gro Nutrition Solutions

Dyna-Gro Nutrition Solutions markets its liquid concentrates under the banner "The Nutrition Solution," positioning them as complete feeds rather than standalone N-P-K fertilizers. The Richmond, California-based company built its lineup, including Bloom 3-12-6, around delivering the full range of essential elements in one concentrated bottle.

Frequently Asked Questions

When should I start applying Bloom 3-12-6?

Apply it just before flower buds appear, since the formula is timed to help trigger the shift from vegetative growth into flowering. Starting earlier, while the plant is still building foliage, doesn't take advantage of the concentrate's high-phosphorus ratio the way pre-bud timing does.

Why is the nitrogen ratio so low compared to phosphorus?

A 3-12-6 ratio deliberately weights the formula toward phosphorus because that's the nutrient most closely tied to bud and flower development, while excess nitrogen at this stage tends to push leafy growth instead. The balanced ammoniacal-to-nitrate nitrogen that remains is included specifically to help keep stems compact rather than stretched.

Can I use this on vegetables, or is it only for ornamentals?

The formula is developed around flowering ornamentals like roses, orchids, and African violets, though the same phosphorus-heavy ratio is common to bloom-stage feeding more broadly. Check label directions for the specific crop you're growing before applying it outside the ornamental use it's built for.

How is this different from an all-purpose fertilizer?

An all-purpose fertilizer usually carries a fairly even nitrogen-to-phosphorus ratio meant to support foliage and flowers at the same time. Bloom 3-12-6 shifts that balance specifically toward phosphorus for the pre-bud window, rather than trying to cover the whole growth cycle in one formula.

Does the container size change how I use the product?

No -- the 8oz, 1gal, and 5gal sizes are the same 3-12-6 concentrate at different volumes, so dosing per gallon of water stays the same regardless of size. Larger sizes simply reduce how often a grower running multiple flowering plants needs to reorder.
