A cold-processed liquid extract of Yucca schidigera, the desert "Tree of Life," packed with natural saponins. One product that improves foliar spray coverage, rehydrates dry or hydrophobic soils, and feeds the soil food web.

Why Use Yucca Extract?

🌧️ Better Foliar Coverage. Saponins flatten beaded water droplets into a thin, even film that coats the entire leaf, top and bottom. Your kelp, fish, and neem applications spread evenly across the leaf surface instead of rolling off.

🌱 Rescues Dry or Hydrophobic Soils. Peat-based mixes, coco coir, and sun-baked beds can reach a point where water just channels off and leaves the root ball dry. Yucca rehydrates these media in minutes and restores even absorption.

🧫 Feeds Soil Biology. Yucca's complex sugars and polysaccharides are a slow-release carbon source for beneficial bacteria, mycorrhizal fungi, and other rhizosphere life. Microbe-safe, unlike synthetic surfactants.

🌾 Supports Stress Tolerance. Saponins and polyphenols (resveratrol, yuccaols) help plants cope with heat, drought, and transplant stress. Research has also shown improved seedling vigor and germination, especially under challenging conditions.

How to Use

Foliar Spray Adjuvant Mix 1.25 to 2.5 ml per litre of water with foliar nutrients to improve spray coverage and nutrient absorption. Apply when grow lights are off, or in early morning or evening.

Soil Drench / Irrigation Use 0.25 to 0.5 ml per litre of water to improve moisture movement and feed soil biology.

Wetting Agent for Hydrophobic Soils Apply 1 to 2 ml per 4 litres (1 gallon) of media volume, or 180 to 360 ml per cubic yard. Dilute well for even application.

A little goes a long way. Yucca is highly concentrated. Over-applying just causes excess foam, not better results.

Pro Tips

• Add yucca LAST when mixing with other amendments. It foams quickly when agitated.
• Don't run a bubbler or air pump right after adding yucca. You'll get a foam volcano. Stir gently and let it settle.
• Don't foliar-spray in direct sun. Yucca's wetting action keeps more solution on the leaf, which can cause burn under intense light. Spray early morning or evening, or when grow lights are off.
• Measure carefully. At these tiny rates, an oral syringe is far more accurate than a spoon.
• Use regularly, not heavily. Small consistent doses beat occasional heavy applications.

Plays Well With

A great tank-mix partner. Add to humic and fulvic acids, ABM, kelp, fish hydrolysate, aloe, neem and karanja oils, and most other liquid amendments to improve mixing and coverage.

Storage

Store in the original sealed container in a cool, dark place out of direct sunlight. Keep above freezing. Sediment may form over time. Lightly tip the bottle side to side to mix before use, do not shake.
