How different pond plants grow and reproduce themselves:
For more details on how to do these repotting tasks: See Repotting a pond plant.
- Grow horizontally across the water surface from a position on a pond shelf or ledge
- Send out runners or stems that extend the plant size and coverage.
- Create places for wildlife to hide.
- Root out from the nodes (where the stem forms new leaf growth) into the water allowing the plant to be viable a long way from the original basket.
- The plant can look straggly at the basket as all the fresh new growth will be some distance away.
To propagate plants of this kind: Cut back the stems with each cutting containing a shoot and a portion of stem with root growth during summer when the plant is in active growth and repot. Or repot new cuttings in an existing basket to thicken up a straggly plant.
- Divide when active by using a knife to split the rhizomes or root clumps if they grow too large or if the centre has become bare or dead.
- Upright plants can form new plants from stem cuttings rooted from the original plant by placing a portion of stem with leaf nodes in water.
- Grow on in a new basket once they have developed roots of their own.
- New bulbils are formed on the end of turions (the long stems which attach the bulbil to the parent plant)
- Separate these from the parent plant and repot
- Some pond plants will set seed to form new plants.
- Use seed straight away when produced on the plant
