Botanicare Pure Blend Pro Bloom Soil is a soil-focused bloom base nutrient for flowering and fruiting plants, built to provide core nutrition through the bloom stage. It’s designed specifically for plants cultivated in soil, where root-zone chemistry and microbial activity can change how nutrients remain available.
This bloom base nutrient is formulated to deliver higher phosphorus levels for soil cultivation, helping offset the way clay colloidal particles can bind phosphorus and the way soil microbes can compete for it. The result is a bloom-stage formula that keeps the focus on consistent phosphorus availability for blooming, fruiting, and flowering plants while also supporting the living biology in the root zone.
Pure Blend Pro Bloom Soil is part of the Pure Blend Pro family and centers on a blend of natural minerals and organic extracts. Alongside that foundation, it provides essential macro and micro nutrients, plus trace minerals from the land and sea, giving the formula a broad nutritional profile intended for bloom performance rather than narrow, single-input supplementation.
As a compact facts layer, this bloom formula is 1-4-5. That NPK balance aligns with what many growers look for during flowering and fruiting: a bloom-oriented base fertilizer that emphasizes phosphorus and potassium support while still providing nitrogen for steady plant function.
Because it’s purpose-built for soil cultivation, Pure Blend Pro Bloom Soil is best suited to soil-based gardens where growers want a dedicated bloom base nutrient that accounts for soil’s unique nutrient-binding behavior. If you’re running flowering and fruiting plants in soil and want a premium bloom fertilizer with trace minerals from the land and sea and a natural-minerals-and-organic-extract foundation, this is a solid fit for growers aiming for steady bloom nutrition without turning the program into a complicated stack.
Step-by-step mixing and feeding instructions for Botanicare Pure Blend Pro Bloom Soil - 1 Quart.
Fill your reservoir or watering container with clean, room-temperature water first. Shake the bottle of Botanicare Pure Blend Pro Bloom Soil - 1 Quart well before every use. Using the feeding schedule below, measure the recommended dose and add it directly to the water while stirring. Allow the solution to mix fully before adding any other fertilizers, additives, or supplements.
Always add nutrients to water — not the other way around. Mix thoroughly between products to ensure an even, stable nutrient solution.
Vegetative stage — Bloom Soil
Flowering stage — Bloom Soil
Warning – Important Safety Information
This product may cause mild skin irritation and eye irritation. Avoid unnecessary contact with skin, eyes, and clothing. Use only as directed.
General safety precautions
Read and follow all instructions on the product label and any accompanying documentation before use. Keep out of reach of children and pets. Do not ingest. Avoid breathing vapours, mist, or dust that may be generated during handling or use.
Wear appropriate personal protective equipment (PPE), such as protective gloves, long sleeves, long pants and closed-toe footwear. When there is a risk of splashing or airborne particles, use safety glasses or other suitable eye and face protection.
First aid – skin contact
IF ON SKIN OR HAIR: Remove contaminated clothing immediately. Rinse skin with clean water for several minutes, then wash with mild soap and water. If irritation or redness develops and persists, seek medical attention. Wash contaminated clothing before reuse.
First aid – eye contact
IF IN EYES: Rinse cautiously with clean water for several minutes, keeping eyelids open. Remove contact lenses if present and easy to do. Continue rinsing. If irritation persists, obtain medical advice.
First aid – ingestion and inhalation
IF SWALLOWED: Rinse mouth thoroughly with water. Do not induce vomiting unless instructed by a medical professional. Seek medical attention if you feel unwell.
IF INHALED: Move the person to fresh air and keep them comfortable for breathing. If coughing, breathing difficulty, dizziness or other symptoms occur, seek medical assistance.

Store this product in its original closed container, in a cool, dry and well-ventilated area. Protect from extreme temperatures and direct sunlight. Keep container tightly sealed when not in use.
Avoid release to drains, natural waterways or outdoor soil. Dispose of unused product and empty containers in accordance with local regulations and the directions on the label.
Important: If medical advice is needed, keep the product label or container available. Always follow the specific instructions and safety recommendations provided by the manufacturer. This safety notice is intended as general guidance and does not replace official label directions or documentation.
| Total Nitrogen (N) | 1.0% |
|---|---|
| Available Phosphate (P2O5) | 4.0% |
| Soluble Potash (K2O) | 5.0% |
| Calcium (Ca) | 1.0% |
| Total Magnesium (Mg) | 0.5% |
Available Phosphate (P₂O₅) supports root development, energy transfer, and early structural growth by providing a form of phosphorus that plants can absorb and use quickly.
Calcium is important because it builds and stabilizes plant cells as they form, acting as the structural support that keeps new growth strong and functional. Unlike other nutrients that drive color or speed of growth, calcium’s role is unique because it controls cell wall strength and membrane stability, making it essential for healthy roots, shoots, and long-term plant resilience rather than quick visual results.
Dolomite gently raises and stabilizes pH while supplying calcium and magnesium, helping roots absorb nutrients more consistently and supporting strong new growth and greener leaves. It’s unique because it buffers acidity and feeds two key minerals at the same time, unlike materials that only change pH or only provide a single nutrient.
Fish meal provides slow, steady nitrogen by breaking down through soil biology, which helps plants build greener leaves and stronger stems over time. It’s unique because it feeds through microbial activity rather than acting instantly, so it’s gentler and longer-lasting than fast nitrogen sources.
Humic acid is important because it improves root health and nutrient uptake by keeping minerals available, stabilizing the root zone, and supporting beneficial biology, which makes growth more consistent. It’s unique because it doesn’t act like a direct nutrient boost—its main power is improving the root environment so plants can use what’s already there more efficiently.
Potassium carbonate is important because it can supply potassium for water movement, stress tolerance, and strong growth, while also pushing the root zone toward higher pH and alkalinity. It’s unique because it doesn’t just “feed potassium” like many other sources—it also changes solution chemistry, so it must be used carefully to avoid micronutrient lockout and calcium/magnesium imbalance.
Soluble potash (K2O) is important because it helps plants control water use, move sugars to new growth and fruit, and build stronger, higher-quality structure under stress. It’s unique from many other nutrients because it acts more like a regulator and transport helper than a direct “building material,” so the biggest benefits show up as steadier growth, stronger stems, and better finishing instead of just bigger leaves.
Total magnesium is important because magnesium powers chlorophyll and energy use, helping plants stay green, turn light into growth, and use other nutrients efficiently—and it’s unique because its problems often come from nutrient balance and uptake competition, not just a simple shortage.
Total Nitrogen is important because it directly drives leafy growth, chlorophyll production, and overall growth speed, which sets the pace for the entire plant. It’s unique because the “total” number can include different nitrogen forms that behave differently in the root zone, meaning the same total amount can produce very different results depending on the nitrogen type and plant stage.
Magnesium sulfate supplies magnesium for chlorophyll and sugar movement plus sulfur for protein building, helping plants stay efficient and green during high-demand growth. It’s unique because it adds magnesium without extra nitrogen or calcium, so it corrects magnesium issues with fewer side effects when balance is the real goal.
Seaweed is mainly a plant booster because it supports roots, stress tolerance, and nutrient efficiency more than it supplies full nutrition. It’s unique because ocean-derived compounds help the root zone and plant growth signals in a gentle way, so plants often recover faster and grow more steadily when the basics are already covered.
