Ecothrive Soil Food Bloom 5kg 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 abundant flowers and fruits 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 improve nutrient availability and help plants access phosphorus, calcium and other important elements during the energy-intensive flowering stage.

Mealworm frass, micronised rock phosphate and additional mineral inputs complement the potassium lignosulphonate, supplying a balanced combination of phosphorus, potassium, calcium, magnesium and sulphur.

The result is a targeted living soil bloom amendment designed 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 balance shifts towards greater 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 change in nutrient demand as plants enter their generative stage.

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 taking advantage of its fulvic-rich characteristics.

Fulvic compounds can act as natural chelating agents, helping keep nutrients available within the root zone and improving the efficiency with which plants can access them.

This is particularly valuable during flowering, when rapidly 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 processes involved in productive flowering and fruit development.

By replenishing potassium as plants move through bloom, Soil Food Bloom helps prevent the soil's existing reserves from becoming a limiting factor during this demanding stage.

Calcium, magnesium & sulphur support

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, while magnesium remains essential to chlorophyll and photosynthesis. 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 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 efficient 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.

Additional mineral nutrition

The complete formulation provides substantial calcium together with magnesium and sulphur, creating a broader flowering amendment rather than a simple 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. Ecothrive advises avoiding further top dressing during the final 4-5 weeks before harvest.

When should Soil Food Bloom be applied?

Soil Food Bloom is intended for early and mid-flowering, rather than being used automatically from the beginning of vegetative growth.

The transition should be based primarily on crop stage. Once plants begin forming flowers, their nutrient demand changes and Bloom becomes more appropriate than Soil Food Grow.

Ecothrive recommends an initial Bloom top-dress when flowers have started to form. A second application 2-3 weeks later may be appropriate for some cultivars, long cycles or situations where soil reserves are depleted more rapidly.

Avoid automatic feeding simply because a particular week has been reached. Container volume, plant size, crop duration, environmental intensity and previous use of the soil 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, always adjusting according to crop stage and plant demand.

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.

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 products are designed to be used sequentially according to crop stage and soil condition, rather than applying all three at the same time.

Designed specifically for Ecothrive Living Soil

Ecothrive Living Soil contains an initial reserve of organic nutrition, meaning newly planted crops do not automatically require additional fertiliser.

As a crop grows and enters flowering, however, nutrient reserves are gradually consumed. Heavy-flowering and fruiting plants can place particularly high demand on phosphorus and potassium.

Soil Food Bloom is designed to replace what the plants have used, extending the productive life of the existing soil without converting the system into a conventional liquid-feeding programme.

This is particularly useful for smaller containers, long crop cycles and high-intensity environments where nutrient reserves can be exhausted more rapidly.

How much soil will a 5kg bag treat?

At Ecothrive's indoor application rate of 1-2g per litre of soil, a 5kg bag provides substantial coverage for larger living soil systems.

At 1g/L, 5kg provides enough Soil Food Bloom for approximately 5,000 litres of calculated soil volume.

At 2g/L, it provides enough for approximately 2,500 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 bed.

For outdoor applications at 100-200g/m², a 5kg bag provides approximately 25-50m² of coverage per application.
