Organic Broad-Spectrum Plant Spray - 32oz
Details
32oz spray bottle — ready to use, no dilution.
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, 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.

How to use Organic Broad-Spectrum Plant Spray
Three simple steps — no expertise required.
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.
Apply
Drench the root zone, mist the leaves, or work into soil — depending on the product. Water in lightly when applying to soil.
Repeat
Most products: every 2–4 weeks during active growth. Reduce or skip during dormancy. Biochar is a one-time application — permanent.
