Frequently Asked Questions
Do I need to repot the plant before putting it in the pond?
Do I need to repot the plant before putting it in the pond?
No. For all sizes the plant stays in its mesh aquatic basket, which is placed straight into the pond without removing it.
How deep should I plant it to begin with?
How deep should I plant it to begin with?
For 1 litre plants, place no deeper than around half the maximum recommended planting depth at first, moving to full depth as the plant establishes. 3 litre plants can go straight onto the shelf at the depth you want, within the stated 0-20 cm planting depth range.
When does it flower?
When does it flower?
It flowers between May and August, producing the spiky seed heads the plant is known for.
What happens if the plant grows tall?

What care does it need after the growing season?
What care does it need after the growing season?
Once the foliage dies back in autumn, trim it back to just above the water surface to tidy the plant; little other maintenance is needed.
Carex grayi is a marginal pond plant suited to pond edges and shelves in full sun to part shade. It gives the pond margin upright, green structure through the season and produces spiky seed heads prized for flower arranging. You can choose a single plant or a pack of three, each supplied ready to place in its mesh basket, with no repotting needed.
Carex grayi is a marginal pond plant grown for its upright clump of leathery green leaves and its unusual, spiky seed heads, which are also cut for flower arranging. It suits pond edges and shelves in full sun to part shade, and gives the pond margin structure and texture through the growing season. Established plants flower between May and August, producing the seed heads the plant is noted for.
Care is straightforward. Once the foliage dies back in autumn, you trim it back to just above the water surface to tidy the plant, which keeps ongoing upkeep to a single seasonal trim.
What you get depends on the option chosen: a single plant in its own mesh aquatic basket, three plants each in their own basket, or one larger plant in a bigger basket. All sizes arrive in their mesh basket, which stays in place at planting, so there is no repotting step before you place the plant in the pond.
The seed heads are the main point of difference from plainer green marginals, since they are valued both for pond planting and for cutting and arranging indoors.
