Plant Magic Soil Bloom — Single-Part Base Nutrient for Flowering Soil Plants
Best for: Soil growers wanting a straightforward, UK-formulated bloom nutrient that won't overcomplicate feeding schedules
Our thoughts
Plant Magic Soil Bloom cuts through the noise of two-part systems and premium imports. It's a solid, proven single-part that's been formulated specifically for UK water — hard or soft — which genuinely matters. The microfauna support angle sets it apart from basic PK-only boosters. One growers return to.
Plant Magic Soil Bloom is a base nutrient designed specifically for the flowering stage of soil-grown plants. It's a single-part mineral feed with an NPK ratio of 2.2–0.5–3.2, loaded with humates, trace elements, magnesium and calcium in the right proportions to support robust bloom development and prevent nutrient lockout. Formulated by Plant Magic's biochemists for UK water conditions, it works cleanly in hard or soft supplies without the pH gymnastics you get with some imported feeds.
How it compares
Plant Magic Soil Bloom sits in the mid-range of soil flowering nutrients.
- Single-part simplicity vs. two-part systems (easier dosing, less guesswork)
- UK-formulated, not imported from the Netherlands or elsewhere — designed for British water
- Emphasises soil microbe support, not just NPK ratios
- Lower cost than premium brands without cutting corners on ingredients
You're getting proper kit at a realistic price, backed by established brand trust.
Usage guidance
When to use
Apply from the start of the second week of flowering through to your final flush. Switch to Soil Bloom when the natural food in your soil begins to deplete, or follow a set feeding schedule depending on your setup.
Dosage
Measure accurately: 3–5ml per litre of nutrient solution. Most growers sit around 3–4ml per litre as a starting point. Shake the bottle well before each use.
How to apply
Highly soluble, so it mixes cleanly whether you're hand-watering or running dripper systems. Mix thoroughly into your water or nutrient tank before feeding.
Best results
Combine with Plant Magic's Bloom Boost during the flowering period for noticeably heavier blooms. It works as a standalone, but pairing it with a PK booster will shift your yield upwards. The magnesium and calcium in Soil Bloom prevent nutrient lock-out, which frees up uptake of everything else you're feeding.
Technical specifications
- NPK Ratio: 2.2 – 0.5 – 3.2 (low nitrogen, high potassium for flowering)
- Key Ingredients: Humates, trace elements, magnesium, calcium
- Formulation: Mineral-based, single-part
- Dosage: 3–5ml per litre
- Solubility: Highly soluble — compatible with hand-watering and irrigation systems
- Designed for: Hard and soft UK water supplies
- Available sizes: 1L and 5L bottles
- Application stage: Flowering (week 2 onwards through to flush)
Who this is for
- Soil growers wanting a simple, single-part bloom feed without multi-bottle confusion
- UK growers who've dealt with imported nutrients that don't quite suit local water
- Anyone looking to prevent nutrient lockout and support soil biology at the same time
- Experienced growers and newcomers alike — straightforward enough to start, good enough to stick with
- Growers running hand-watering or drip irrigation setups (works with both)
Our take
This is a properly thought-through bloom nutrient that treats UK water as a genuine consideration, not an afterthought. The microfauna support is the bit that matters — it keeps your soil biology active when feeding intensity ramps up, which translates to better nutrient uptake and cleaner growth right through to harvest.
Good time to buy while stock lasts. Does exactly what it should, day in, day out.
