  • water dropWater

    The Running Postman or Kennedia prostrata should be watered deeply but infrequently, to encourage a strong root system. During the growing season, water approximately once a week with about 1-2 gallons per plant, ensuring the soil is moist but not waterlogged. Reduce watering in the cooler months or during periods of rainfall, possibly to once every two to three weeks. Overwatering can lead to root rot, so allowing the soil to dry out slightly between waterings is beneficial.

  • sunLight

    The Running Postman plant thrives in full sun to partial shade. It is best to place it in a location where it can receive at least 6 hours of direct sunlight per day. However, it can also tolerate some light shade, especially during the hottest part of the day, which can help prevent the leaves from scorching.

  • thermometerTemperature

    For the Running Postman, ideal temperature conditions range from 50°F to 85°F. It can tolerate a minimum temperature down to around 20°F but sustained cold can damage or kill the plant. It prefers mild to warm climates and may require protection or mulching in areas with harsh winters.

  • scissorsPruning

    Pruning the Running Postman encourages bushier growth and more abundant flowering. Prune in late winter or early spring before new growth begins. Remove dead or damaged stems and shape the plant to maintain its desired form. It's often sufficient to prune once a year during this time.

  • circleLife cycle

    Running Postman (Kennedia prostrata) begins its life cycle when seeds germinate, often following a fire or soil disturbance that breaks seed dormancy. The seedling establishes a root system and develops a low-lying, prostrate stem that runs across the ground. As the plant matures, its trifoliate leaves, consisting of three leaflets each, develop along the stems. It enters a reproductive phase, producing distinctive red or pink pea-like flowers which are pollinated by bees and other insects. Following pollination, the plant produces seed pods that mature, dry, and eventually split open to release seeds back into the soil. This cycle repeats as seeds germinate and give rise to new plants, continuing the species' survival.

      Spring-Early Summer

    • Running Postman or Kennedia prostrata can be propagated by seeds, which is the most popular method. The best time for sowing the seeds is in the spring after the last frost when the soil begins to warm. First, the hard seed coat needs to be scarified or nicked slightly to encourage germination. This can be done by gently rubbing the seed with sandpaper or nicking it with a knife. After scarification, the seeds should be soaked in warm water for about 12 hours to further soften the coat. Plant the seeds in well-draining soil at a depth of around 1/2 inch (about 1.25 centimeters). Keep the soil consistently moist until germination, which typically occurs within two to three weeks. Once seedlings emerge and establish, they can be transplanted to their desired location in the garden.
