Oxygenating plants are dropped loose into the pond water either with or without a lead strip to bunch them together dependent on the species of the plant. They do not need to be planted up as they float freely in the water, up and down according to the water temperature.
Plants ready potted for a pond:
Both aquatic compost and mesh baskets are a must for any plants that will be submerged into water in a basket so ours are correctly planted up ready for you to lower into the water when they arrive.
Our pond plants and waterlilies are potted into a clay/loam mix aquatic compost.
You cannot use ordinary, multipurpose potting compost for pond plants as this is too light and will contain peat (which will continue to decompose when submerged in water and rot the plant roots) or coir (which will float away when submerged).
Aquatic soil is available in bags in most garden centres and should be brown in colour and not black.
When you divide or repot pond plants into new, larger mesh baskets and aquatic soil you should add a fertiliser tab too.
Our pond plants are supplied in mesh aquatic baskets. These mesh baskets are available in various sizes and allow water to circulate through the compost allowing the transfer of oxygen and nutrients between the water and the plant. The compost should not wash away through these fine holes as the plants are rooted and the root growth will hold the soil together.
The mesh holes allow the plant roots to escape from the cramped conditions inside the basket and stretch out into the water to get even more contact between the roots surfaces and the water to soak up even more nutrients from the water. Some water plants, like waterlilies, can have as large a root spread as their leaf spread is on the surface of the water.
As a plant grows it should be moved into a larger mesh basket and the space filled with aquatic compost or washed gravel.
