This package includes four bunches of live hornwort, with three stems per bunch. Hornwort thrives in a variety of water conditions and does not require substrate, making it suitable for beginners and experienced hobbyists alike. The collection adds natural shelter, improves oxygen levels, and enhances fish habitat with its flexible, fast-growing foliage.
Floating Flowering Plant – Water Hyacinth

Water hyacinth is a fast-growing floating plant that enhances pond oxygenation, provides natural filtration by absorbing nitrates and ammonia, and offers shade to reduce algae and evaporation. This bundle includes one common water hyacinth per purchase, ideal for ponds needing surface coverage and nutrient uptake. It’s well-suited for warmer seasons and should be managed to prevent overgrowth.
Aquascape Pond Plant Potting Media

Specialized aquatic plant soil designed to promote healthy root establishment and robust growth for pond plants. The peat-free and compost-free formula helps maintain clear water quality by reducing floating debris and excess nutrients that can trigger algae blooms. Compatible with water lilies, lotuses, marginal plants, and other aquatic vegetation, this soil supports long-term plant health in pond environments.

Once-a-year fertilizer with an 11-3-14 NPK ratio, designed as a time-release solution that supports healthy plant growth for up to 180 days. The formula emphasizes essential nutrients for robust blooms and overall plant vitality while avoiding excessive nitrogen that can stress plants or encourage algae. Easy to apply and long-lasting, it minimizes maintenance while sustaining pond flora.
Buying Guide
Key factors to consider when selecting oxygenating plants and related supplies for ponds:
- Oxygenation impact: Choose fast-growing, hardy plants such as hornworts and water hyacinth for rapid oxygenation and surface shading.
- Water temperature: Some live plants prefer warmer temperatures and may struggle in freezing conditions; plan according to your local climate and seasonal patterns.
- Water quality: Substrates and fertilizers should support plant health without increasing nutrient levels that promote algae blooms; opt for peat-free soils and controlled-release fertilizers where possible.
- Maintenance: Hornwort and water hyacinth offer low-maintenance options, while live plants require monitoring of growth and potential trimming to prevent overcrowding.
- Fish and wildlife compatibility: Ensure fertilizers and soils are safe for aquatic life; avoid products with harsh chemicals in ponds housing fish and invertebrates.
- Storage and placement: Planting media should be compatible with your pond bottom, while floating plants like hyacinth require ample surface space and regular pruning.
- Seasonal planning: Use fertilizers as a seasonal boost during spring and summer, and consider overwintering strategies for hardy plants in colder regions.
