Product overviewHORTISORB™ is a potassium polyacrylate superabsorbent designed to improve germination, establishment and survival in new flower plantings and lawns. It promotes uniform sprouting, faster rooting and more consistent site appearance for horticultural and landscaping projects.
Main issueLow substrate water-holding capacity and rapid dry‑down that reduce germination and transplant survival.
Application- Horticulture and ornamental beds
- Potted plants and containers
- Nurseries and transplant production
- Soilless substrate mixes
- Greenhouses
- Urban landscaping and new lawn establishment
Geographical areaGreenhouses, urban and municipal landscaping, commercial and residential planting sites
TypesHORTISORB™-24 | HORTISORB™-22 | HORTISORB™-25 | HORTISORB™-24N
Dosage and application instructionsFor soil mixes: blend HORTISORB™ powder thoroughly with the substrate at a ratio of 1:200 (product:substrate by weight). After planting, water thoroughly to activate the polymer.
For transplanting: apply HORTISORB™ equal to 0.5% of the substrate weight. Prepare a hydrogel by mixing product with water at a 1:200 ratio, soak for approximately 30 minutes, then mix the hydrogel evenly into the substrate and water after planting.
Features- High water retention: absorbs and retains approximately 200–500 times its weight in water and releases moisture to plants during dry periods.
- Improved establishment and survival: supports root development and stabilizes substrate moisture after transplanting.
- Enhanced nutrient efficiency: adsorbs and slowly releases nutrients, improving fertilizer use efficiency.
- Extended flowering: can prolong bloom period for ornamental plantings.
- Reduced irrigation needs: field tests and user reports indicate up to ~50% irrigation reduction while maintaining healthy growth.
FAQs — key points- Benefits: better germination rates, more uniform sprouting, higher survival of flowers and turf, and smoother project execution.
- Mode of action: superabsorbent potassium polyacrylate that increases substrate water holding and helps retain nutrients.
- Use cases: ideal for flower beds, pots, nursery trays, soilless mixes and new lawns.
- Expected results: faster establishment, more uniform germination and improved overall survival and aesthetics.
