Quick Reference

Zones

Plant Hardiness Zones describe the average minimum winter temperature for a region. They tell you where a plant can reliably survive outdoors. For example, Zone 5 can handle colder winters than Zone 9. Matching a plant to your zone increases the chance of long-term success.

Days

  • For food crops: Days to maturity is the expected number of days from planting to first harvest. This helps gardeners plan their growing season and time their harvests.
  • For non-food plants: Days to germination indicates how long it usually takes seeds to sprout under normal conditions. This is key for starting seeds successfully.

Types

  • F1 (Hybrid): A cross between two parent varieties. Hybrids are bred for vigor, uniformity, and specific traits such as disease resistance. Seeds saved from F1 plants don’t grow true to type. That means if you try to regrow them from seed, the plant won't necessarily be the same as last year's
  • OP (Open-Pollinated): Varieties that naturally pollinate and remain stable across generations. Seeds can be saved and replanted with consistent results.
  • HM (Heirloom): An open-pollinated variety that has been handed down for many generations. Heirlooms are valued for flavor, tradition, and genetic diversity.

Grows

  • Outdoors: Well-suited for garden beds, raised beds, or open soil, where natural conditions are stable.
  • Windowsill: Compact plants that thrive in containers indoors, often needing only modest light.
  • Anywhere: Highly adaptable plants that perform reliably in both indoor and outdoor settings.

Lifecycle

  • Annual: Grows, flowers, sets seed, and dies in one growing season. Many vegetables and flowers are annuals.
  • Perennial: Lives for multiple years, regrowing each season after going dormant. Often used in landscaping or long-term food crops.
  • Sp. Perennial (Self-Perennializing): A plant that reseeds itself or self-pollinates, giving the effect of perennial growth even if individual plants live shorter lives.

Size

Indicates the recommended container size or soil depth for best growth.

  • “X″ Pot”: The ideal pot diameter (e.g., 5″ Pot), ensuring enough root space.
  • DS (Deep Soil): Requires planting directly in the ground or in a deep raised bed, as shallow pots restrict growth.

  • Dense Growth: Thrives as a low-growing annual with a dense cover, featuring extensive stolons and lush leaves, making it an effective natural weed barrier.
  • Optimal Planting Conditions: Best sown in early spring; simply broadcast and rake in seeds to a depth of 2 cm in well-draining soil. Requires regular watering for optimal growth.
  • Harvesting Strategy: Mow the clover promptly when it begins to bloom to prevent reseeding and encourage thicker vegetative growth.
  • Culinary & Utilitarian Use: Acts as a superior green manure crop, enriching the soil with nitrogen, ideal for rotating in garden rows or covering walkways.
  • Environmental Benefits: Sub clover is a short rotation crop that reduces the need for chemical herbicides and enhances soil fertility, suitable for a variety of climates.

Subterranean Clover Seeds are a powerful addition to any garden, offering a natural solution for weed suppression and soil enrichment. This dense, low-growing cover crop is perfect for garden walkways and large planting areas, providing a lush green manure that fixes atmospheric nitrogen into the soil. Plant in early spring by broadcasting seeds and lightly raking them into the soil. Regular watering will ensure a robust, healthy crop.

Once the clover begins to bloom, mow it down to prevent reseeding and encourage thicker vegetative growth. This practice not only enriches your soil but also reduces the need for chemical inputs, making it a sustainable choice for eco-friendly gardening. Transform your garden's health and productivity with Subterranean Clover, the ideal choice for enhancing soil fertility and reducing chemical herbicide use.

Plant growth and coverage

  • Low-growing, stoloniferous, dense mat-forming habit; excellent natural weed suppressant
  • Height: 5–15 cm (2–6 in)
  • Spread: carpets laterally via stolons to form a thick ground cover
  • Spacing: broadcast evenly for full coverage; target 150–250 plants/m² (or spot-sow 7–10 cm apart)

Choosing a packet size

  • 250 g is ideal for home gardeners establishing ground cover in a few beds, paths, or a small courtyard area.
  • 500 g suits medium gardens, multiple raised beds, or refreshing walkways and row middles across the season.
  • 2 kg is a good fit for large gardens, community plots, orchard alleys, or small acreage looking for reliable green manure and weed suppression.
  • 4 kg is best for landscapers, market growers, and larger properties needing broad coverage across extensive beds, meadows, or pathways.
GROWING INSTRUCTIONS

Sow Subterranean Clover seeds in early spring by broadcasting them over the desired area. Lightly rake the seeds into the soil to a depth of about 2 cm. Ensure the soil is well-draining and keep it moist for optimal germination.

Germination occurs within 7-14 days. Once seedlings appear, monitor their growth, ensuring they receive regular watering. If necessary, thin the plants to avoid overcrowding and promote healthy development. No transplanting is needed as the clover spreads naturally.

To maintain the clover and enhance its benefits, mow it down when it begins to bloom to prevent reseeding. This encourages thicker growth and maximizes nitrogen fixation. At the end of the season, incorporate the clover into the soil as green manure to enrich the planting bed for the next season.
