Care Tips -  Divide in Spring after 2-3 years growth. Cut back leaf stems in Autumn to above water level as any Pontederia has hollow stems. They have a high cellulose content that will disperse into the water if allowed to rot down. Read more about encouraging insect pollinators to your pond. Pontederia also help dragonfly and damselfly larvae to emerge from the pond.
Extra info - Pontederia cordata lancifolia (Slender Pickerel Weed) needs to be planted on a deep shelf to protect the crown in winter. Previously Pontederia lanceolata.

Will my plants arrive potted?

Yes, all our 9cm, 11cm and 23cm Marginal Pond Plants, Deep Water plants and Waterillies will be sent out to you pre-planted in a mesh basket with our aquatic compost and will have been fed with an aquatic feed ball.

Bunched and loose Oxygenators will be sent out bareroot or bunched with a weight and can be dropped straight into the pond as they are delivered .

Moist plants are sent out in solid pots that you would remove before planting into the soil. 

Can Koi fish or ducks eat my plants?

Yes, they may well do. We cannot guarantee that any plants will survive hungry fish and ducks. We would recommend going for Iris or woodier stemmed plants and forming some sort of barrier between the plants and any large fish or wild fowl.

How does my order arrive?

Plant orders are dispatched to UK destinations only but we cannot send to Northern Ireland. Your order will be picked in the Nursery and will be sealed in airtight, waterproof packaging to keep it fresh during transit. Please unwrap all plants from the packaging as soon as possible and place in the situation/depth specified on each plant ticket.
