It's not you.
It's your soil chemistry.

We sent three real soil types to an independent certified lab with and without Blossom. The results confirm what your plants have been trying to tell you.

What Blossom Delivers

Real results for every growing situation

Two mixes, tested in three real soil types. Here's what the lab found.

🌿

Outdoor Garden Mix

Tested in sandy soil & clay soil

✓
Explosive root growth & flowering Phosphorus powers root development and bloom set — critical for fruiting vegetables and flowering plants.
9×
✓
Disease resistance & drought tolerance Potassium hardens cell walls and regulates water uptake. Sandy soil went from critically deficient to fully stocked.
11×
✓
Richer, greener foliage Magnesium is the core atom of chlorophyll. Sandy soil had almost none. Blossom delivered an 11× increase for full photosynthesis.
11×
✓
Nutrients that stay in the root zone CEC raised 5.5× in sandy soil — nutrients stay available through rain and irrigation instead of washing away.

Indoor Plant Mix

Tested in commercial potting soil

✓
Bloom-triggering phosphorus Standard potting mixes deplete quickly. Blossom raised phosphorus 20× — unlocking consistent flowering in containers.
20×
✓
Stronger stems & even hydration Calcium and magnesium build cell walls and balance water distribution — both saw 4–5× increases.
4–5×
✓
Nutrients that stay put between waterings CEC boosted by 70% in potting mix — every watering delivers nutrition to roots instead of straight through the drainage hole.
+70%
✓
pH unlocks hidden nutrients Potting mix at pH 7.1 locks away iron and zinc. Blossom corrected to ideal 6.5 — making existing nutrients accessible.

pH Correction

Unlocking nutrients already in your soil

Soil pH is the master switch for plant nutrition. At pH 7.5+, iron, manganese, zinc, and phosphorus become chemically bound — unavailable to roots no matter how much fertilizer you add. Blossom moved every soil type to the 6.2–6.5 sweet spot where nutrients flow freely.

Long-Term Soil Health

Soil that keeps feeding your plants

Cation Exchange Capacity (CEC) measures your soil's nutrient bank account — how much it can store and keep available to roots. Higher CEC means nutrients stay in the root zone instead of washing away with every rain or watering.

Sandy Soil
Before
4.1
→
After
22.5

A 5.5× CEC increase — fast-draining sand transformed into a productive substrate. Nutrients that used to wash straight through now stay in the root zone.

Potting Mix
Before
19.1
→
After
32.4

A 70% CEC boost in containers — every watering now delivers nutrition to roots instead of draining straight out the bottom.

Clay Soil
Before
18.9
→
After
28.7

A 52% CEC improvement — clay already stores nutrients but often in locked ratios. Blossom improved storage and corrected the balance so nutrition actually reaches roots.

Nutrient Balance

The right ratios matter as much as the amounts

Soil can be loaded with nutrients and still starve your plants if the Calcium/Magnesium/Potassium ratios are skewed. Blossom shifted all three soils toward the agronomically ideal base saturation profile — where nutrients cooperate rather than compete.

Sandy Soil

Outdoor Mix

Before: 73% Calcium (Ca), almost no Potassium (K) or Magnesium (Mg). After: Mg at 45%, K at 10% — a full nutrient spectrum now accessible to roots.

Clay Soil

Outdoor Mix

Before: 78% Ca, K at just 2% — classic clay imbalance. After: K at 10%, Mg at 44%, Ca at 33% — a productive, balanced growing profile.

Potting Soil

Indoor Mix

Before: 77% Ca, K at 6.7%. After: K at 10.5%, Mg at 43% — the profile houseplants need to flower and fruit reliably.

Your soil is ready to be transformed.
