Ecothrive Soil Food Bloom 1kg is a premium organic top-dress soil amendment formulated specifically for flowering and fruiting plants grown in living soil. With a typical NPK analysis of 2-8-6, Bloom reduces nitrogen while increasing phosphorus and potassium to replenish the nutrients plants demand as they move from vegetative growth into flower and fruit production.
Soil Food Bloom forms the flowering stage of Ecothrive's complete Soil Food system. It is designed to replace nutrients as plants use them, supporting productive flowering and fruiting while maintaining the biologically active soil ecosystem responsible for nutrient cycling.
At the heart of the formulation is potassium lignosulphonate, an organic potassium source rich in fulvic compounds. Ecothrive uses this material not only to supply potassium but also to support nutrient availability and help plants access phosphorus, calcium and other important elements during the energy-intensive flowering stage.
Mealworm frass, micronised rock phosphate and complementary mineral inputs combine with the potassium lignosulphonate to supply phosphorus, potassium, calcium, magnesium and sulphur.
The result is a targeted living soil bloom amendment designed primarily for early and mid-flowering, when plants are rapidly forming flowers and fruits and their demand for phosphorus and potassium increases.

Targeted nutrition for flowering & fruiting
Plant nutritional demand changes as vegetative growth gives way to flowering and fruit production.
Nitrogen remains important, but the nutritional balance shifts towards increased phosphorus and potassium demand. Soil Food Bloom reflects this change with a typical analysis of:
-
Nitrogen (N): 2%
-
Phosphorus pentoxide (P₂O₅): 8%, equivalent to approximately 3.5% elemental phosphorus
-
Potassium oxide (K₂O): 6%, equivalent to approximately 5% elemental potassium
-
Calcium: 10%
-
Magnesium: 1%
-
Sulphur: 2.5%
-
Fulvic compounds: 2.5%
Compared with Soil Food Grow, Bloom contains less nitrogen and substantially more phosphorus and potassium, matching the shift in plant demand as flowering begins.
Potassium lignosulphonate & fulvic compounds
The defining ingredient in Soil Food Bloom is potassium lignosulphonate.
Lignosulphonates are derived from lignin, a natural structural component of plants. In Soil Food Bloom, Ecothrive uses potassium lignosulphonate as an organic potassium source while also taking advantage of its fulvic-rich characteristics.
Fulvic compounds can help chelate nutrients and maintain their availability within the root zone, supporting efficient nutrient uptake.
This becomes particularly useful during flowering, when developing flowers and fruits place increased demand on the soil's reserves of phosphorus, potassium, calcium and other essential elements.
Ecothrive also highlights the soluble carbon and wood-derived sugars associated with this ingredient, which provide an additional energy source for soil microorganisms.
Phosphorus for sustained flower formation
Soil Food Bloom contains 8% P₂O₅, equivalent to approximately 3.5% elemental phosphorus.
Phosphorus is essential for plant energy transfer, root function and reproductive development. Demand becomes particularly important as plants establish flowering sites and begin producing flowers and fruits.
Micronised rock phosphate forms part of the Bloom formulation, helping maintain phosphorus availability through the early and mid-flowering stages.
The fulvic compounds supplied by potassium lignosulphonate further support the availability and uptake of phosphorus and other nutrients within the soil.
Potassium for flowers, fruits & crop quality
Potassium is heavily utilised by productive flowering and fruiting plants. Soil Food Bloom contains 6% K₂O, equivalent to approximately 5% elemental potassium.
Potassium contributes to water regulation, enzyme activity, carbohydrate movement and numerous physiological processes involved in productive flowering and fruit development.
Replenishing potassium during bloom helps prevent the soil's existing reserves from becoming a limiting factor as crop demand increases.
Calcium, magnesium & sulphur support
Effective flowering nutrition is not simply a matter of increasing phosphorus and potassium. Plants continue to require calcium, magnesium and sulphur throughout the generative stage.
Soil Food Bloom contains 10% calcium, 1% magnesium and 2.5% sulphur, helping replenish these important secondary nutrients alongside its NPK nutrition.
Calcium contributes to normal cell-wall development and structural integrity. Magnesium remains essential to chlorophyll and photosynthesis, while sulphur is required for amino acids, proteins and numerous plant metabolic processes.
Support flowering plants & living soil biology
Soil Food Bloom is designed to nourish flowering plants without abandoning the biological principles of living soil.
Mealworm frass in the form of Ecothrive Charge contributes organic nutrition while supporting microbial activity and nutrient cycling.
The potassium lignosulphonate component also supplies soluble carbon and wood-derived sugars that can provide an energy source for soil microorganisms.
This allows Bloom to replenish nutrients required by flowering plants while continuing to support the soil ecosystem responsible for processing and cycling organic nutrition.
Key ingredients in Soil Food Bloom
Potassium lignosulphonate
The defining Bloom ingredient, supplying organic potassium together with fulvic-rich compounds that support nutrient availability and uptake.
Mealworm frass - Ecothrive Charge
Provides an organic input that supports microbial activity and nutrient cycling during the energy-intensive flowering stage.
Micronised rock phosphate
Provides a finely ground source of phosphorus to help maintain phosphorus availability during sustained flower and fruit production.
Complementary mineral nutrition
The complete formulation provides substantial calcium together with magnesium and sulphur, making Soil Food Bloom a broad flowering amendment rather than simply a phosphorus and potassium booster.
How to use Ecothrive Soil Food Bloom
Soil Food Bloom should be top-dressed as plants enter the flowering or fruiting stage.
For established indoor plants, use 1-2g per litre of soil, calculating the required quantity from the soil volume within approximately the top 15cm of the pot or bed.
Spread the measured amendment evenly over the soil surface, lightly scratch it into the top 2-4cm and water after application.
For established plants in approximately 40-60L pots, Ecothrive recommends applying Bloom during the early generative stage once flowers have started to form.
Some cultivars and longer flowering cycles can benefit from a second application approximately 2-3 weeks later. Avoid further top dressing during the final 4-5 weeks before harvest.
When should Soil Food Bloom be applied?
Soil Food Bloom is intended primarily for early and mid-flowering.
The transition from Grow to Bloom should be based on crop stage rather than simply following a rigid calendar. Once flowers begin to form, the plant's nutrient requirements change and Bloom becomes more appropriate than the vegetative Soil Food Grow formulation.
Ecothrive recommends an initial Bloom top-dress once flowers have started to form. A second application 2-3 weeks later may be appropriate for some cultivars, longer flowering cycles or situations where soil reserves are being depleted rapidly.
Container volume, plant size, crop duration, environmental intensity and previous use of the soil can all influence nutrient demand.
Using Soil Food Bloom outdoors
Soil Food Bloom can also be used with established flowering and fruiting crops grown in field or garden soil.
Apply 100-200g per m² as a top dressing.
Spread evenly across the soil surface, scratch into the top 2-4cm and water after application.
Ecothrive's general outdoor Soil Food guidance is to repeat applications approximately every 4-6 weeks where required, adjusting according to crop stage, plant performance and soil condition.
Grow, Bloom & Re-Gen - the Ecothrive Soil Food system
Soil Food Bloom forms the generative stage of Ecothrive's three-product organic powdered nutrient system for living soil.
Soil Food Grow
Use during vegetative growth to replenish nitrogen and balanced nutrition required for strong roots, stems and foliage.
Soil Food Bloom
Transition to Bloom as flowers begin to form. Its lower nitrogen and increased phosphorus and potassium are designed to match the nutritional demands of flowering and fruiting plants.
Soil Food Re-Gen
After harvest, use Re-Gen to replenish depleted living soil and prepare it for another crop.
The three products are designed to be used sequentially according to crop stage and soil condition, rather than routinely applying them together.
Designed specifically for Ecothrive Living Soil
Ecothrive Living Soil contains an initial reserve of organic nutrition, so newly planted crops do not automatically require additional fertiliser.
As plants develop and enter flowering, those nutrient reserves are gradually consumed. Productive flowering and fruiting plants can place particularly high demand on phosphorus and potassium.
Soil Food Bloom is designed to replace what plants have used, extending the productive life of the existing soil without converting the system into a conventional liquid-feeding programme.
This approach is particularly useful in smaller containers, long crop cycles and high-intensity environments where nutrient reserves can be exhausted more rapidly.
How much soil will a 1kg bag treat?
At Ecothrive's indoor application rate of 1-2g per litre of calculated soil volume, a 1kg bag provides useful coverage for multiple containers or a smaller living soil bed.
At 1g/L, 1kg provides enough Soil Food Bloom for approximately 1,000 litres of calculated soil volume.
At 2g/L, it provides enough for approximately 500 litres.
For indoor containers and beds, Ecothrive recommends calculating the application from the soil volume within approximately the top 15cm, rather than automatically using the entire volume of a deep container or bed.
For outdoor applications at 100-200g/m², a 1kg bag provides approximately 5-10m² of coverage per application.
