Details

32oz spray bottle — ready to use, no dilution.

Ready-to-use foliar spray that delivers nutrition directly through the leaves. For houseplants, orchids, and succulents that look tired between waterings — no mixing, no measuring, just spray and grow.

Foliar feeding works because leaves are absorbent. When a plant looks tired between waterings, it's often telling you it can't pull what it needs through its roots fast enough. The Indoor Houseplant Spray bypasses that. A fine mist of broad-spectrum organic nutrition — nitrogen, phosphorus, potassium, calcium, magnesium, silica — delivered straight to where the plant uses it. Fish emulsion, fish manure, sea kelp, silica, aloe vera, finished with peppermint oil. Ready to use straight from the bottle, no PPE, safe around kids and pets when used as directed.

Results

Visible improvement within days, not weeks. Glossier leaves. Stronger new growth. Faster correction of nutrient deficiencies. A complement to root-zone feeding, not a replacement.

Ingredients

Fish emulsion, fish manure, sea kelp, silica, aloe vera, peppermint oil. Broad-spectrum macros and micros.

How to use

General misting: spray leaves until lightly coated, top and underside. Weekly during active growth, monthly during dormancy. Timing: spray in the morning so leaves dry before evening — wet leaves overnight invite fungal issues. Sensitive plants: succulents, cacti, and orchids — monthly only, lighter mist.

Frequently asked

How is this different from the Indoor Houseplant Food?

The Food feeds through the roots over weeks. The Spray feeds through the leaves in days. Use both — Food for steady nutrition, Spray when a plant needs a fast boost or you spot a deficiency.

Will it stain my floors or furniture?

A fine mist applied to leaves shouldn't drip in any meaningful volume. If you over-spray, wipe up promptly; some natural inputs can leave a faint mark on porous surfaces.

Is it safe on edible herbs?

Yes. OMRI Listed for organic use; rinse before eating.

Can I spray succulents?

Sparingly — monthly at most, light mist only. Succulents are prone to rot when their leaves stay damp.

How often should I spray?

Weekly during active growth, monthly during dormancy. Skip the week after repotting or any major stress event.

Why does my plant look the same after one spray?

Most plants show visible difference in 5–10 days. If nothing changes after three weekly applications, the issue is usually light, water, or roots — not nutrition.

Application guide

How to use Organic Indoor Houseplant Spray

Three simple steps — no expertise required.

1
Measure

Open the bottle or bag and follow the dilution rate on the label. Liquids: 1–2 oz per gallon of water. Biochar: one cubic foot per 64oz bag.

2
Apply

Drench the root zone, mist the leaves, or work into soil — depending on the product. Water in lightly when applying to soil.

3
Repeat

Most products: every 2–4 weeks during active growth. Reduce or skip during dormancy. Biochar is a one-time application — permanent.

The 3-in-1 advantage

Plants need
what you need.

Food. Vitamins. Probiotics. Most products give you one. Ours gives you all three.

Food
Macronutrients
N · P · K

Nitrogen, phosphorus, and potassium. The fuel that makes things grow. You can survive on food alone for a while — but you won’t thrive.

Vitamins
Micronutrients
Trace minerals

Calcium, magnesium, iron, zinc, sulfur. The supporting cast that makes your food actually work. Without these, even the best diet falls flat.

What makes us different
Probiotics
Probiotics
Living microbiome

Billions of beneficial microbes that live alongside roots — same principle as gut bacteria for humans. They unlock nutrients, fight disease, and keep the whole system humming.

The science inside

300+ species.
Billions of each.
All in one bag.

Our biochar is studied in a multi-year USDA ARS field trial. Initial results suggest the curated microbial community we pre-load it with contains rare plant growth-promoting species not present in raw or uncharged biochar.
