Oxygenating Plant 
 
Common Name - Hornwort
 
Supplied as - Loose plant stems and pieces sent barerooted ready to drop into pond - it breaks on attempts to bunch it as it is very brittle. Pieces can be small pieces that become dormant buds ready to regrow. A portion is measured out in a rice takeaway dish but wrapped in newspaper & a plastic bag for sending. Multiple portions ordered are sent together in one newspaper package/bag. (Not sent in the plastic dish to each customer).
 
Planting Depth - Drop into deep water of your pond/container pond and the plant will float to find its own depth dependent on water temperature
 
Colour - Dark green/black or olive green brush-like foliage depending on time of year
 
Flowers - N/Ar
 
Aspect - Sunny/Partially Shaded
 
Origin - British Native
 
Care Tips - Allow Ceratophyllum demersum (Hornwort) to grow until you have 30% of your pond volume filled then remove some by hand - take out any clear stems not the dark green/olive brown stems in summer months. Follow this link for more advice on oxygenating plants. 
 
Extra info -  The bulk of Hornwort will drop down to the bottom of the pond in winter & break down into small buds to protect itself from frost and ice. In a new pond, the stocking rate of oxygenating plants should be 2/3 portions per m² of surface area. 

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.
