Details

Case of 12 × 32oz spray bottles — retail-floor pack.

The outdoor version of foliar feeding. Ready-to-use spray for vegetables, herbs, flowers, trees, and shrubs — same broad-spectrum organic nutrition, no mixing, no PPE, safe around kids and pets when used as directed.

Outdoor plants live with more stress than indoor ones: weather, pests, transplant shock, the heat of late summer. Foliar spraying gives them a fast-acting boost they can't always get from the root zone. Built from the same organic inputs as our liquid food — fish emulsion, fish manure, sea kelp, silica, aloe vera — finished with peppermint oil. OMRI Listed, CDFA approved, ready to use straight from the bottle.

Results

Faster recovery from transplant. Faster correction of nutrient deficiencies — yellowing leaves, weak new growth, stalled flowering. Stronger top growth that holds up through heat and drought.

Ingredients

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

How to use

Routine feeding: spray leaves until lightly coated, top and underside. Weekly during active growth. Stress response: use whenever plants look tired, after transplant, or during a heat wave. Timing: apply in early morning or late afternoon — never during the hottest part of the day. Avoid spraying within 24 hours of a heavy rain event.

Frequently asked

When should I foliar-spray vs. feed at the roots?

Root feeding is steady nutrition over weeks. Foliar spraying is a fast boost — best for stress events, visible deficiencies, or supplementing during peak growth.

Can I use it on vegetables I plan to eat?

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

How close to harvest is it safe?

No required waiting period. For aesthetics, avoid spraying within 48 hours of picking — leaves look better without residue.

Will it harm beneficial insects?

It's a nutrient spray, not a pesticide. Bees, ladybugs, and pollinators are fine — but avoid spraying directly onto active pollinators.

Can I mix it with other sprays?

Compatible with most organic foliar products. Don't combine with synthetic chemical sprays or copper-based fungicides without testing on a small area first.

Does it work on lawns?

For lawn applications, our Liquid Lawn & Turf Food is the right product — formulated specifically for turf, with a different application method.

Application guide

How to use Organic Broad-Spectrum Plant 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.

*Dr. Earth lists mycorrhizae in their ingredient panel — viability of those microbes by the time they reach soil is the open question. Our biochar pre-loads live, active microbes the moment it hits the ground.

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.
