Waterlilies for surface cover in the pond

Waterlilies for surface cover in the pond

Hopefully the sun will return soon. Do you need more waterlilies to add extra surface cover to your pond?

Now is a good time to add waterlilies of the correct size to your pond.

Waterlilies are the favourite surface cover plants for a pond:

  • They have leaf spread and colourful flowers in Summer.
  • The aim is to cover half to two thirds of the pond water surface in Summer with plant leaf growth.
  • This keeps the water cooler and shaded below the surface to help avoid blanketweed and algae.
  • Choose the size of waterlily that will achieve this spread in your pond in about 3 years.

Another plant that will give surface cover over the pond over time is Frogbit (Hydrocharis morsus-ranae):

  • These are sent as 3 barerooted plantlets that float freely on the water surface and rise and fall with the water temperature.
  • They drop to the base of the pond in Winter as dormant buds that look like apple pips.
  • They are slow to spread in their first year but multiply well over time.

More details about Waterlily Size and Spread:

  • Water lilies are available in sizes from Miniature for container ponds or Butler sinks through to large Pond waterlilies for big surface area ponds.
  • All waterlilies are sent rooted in a mesh basket & aquatic soil.
  • Miniature and Dwarf waterlilies are sent in 11cm /4” baskets, Pond waterlilies are sent rooted in 2 sizes of basket - 15cm/6" and 23cm/9" across.

The Miniature waterlilies are only suitable for a barrel pond or a very small pond. The whole plant may only reach 15cm/6inches across - the size of a side plate.

  • Each leaf and flower only reaches 3cm(1 inch) wide.

Dwarf waterlilies are slightly larger in spread across the pond surface with each leaf around 6cm(2 inches) wide.

  • Aurora is the smallest and almost like a Miniature.

The larger Pond waterlilies in 23cm baskets can have a single leaf 9-11cm/3-4'" wide.

  • The medium Pond waterlilies in 15cm baskets are smaller in size of leaf and plant spread.
  • There is only one British Native waterlily - Nymphaea alba. This is a white waterlily and one plant can spread up to 2m across.
  • The medium pond white waterlily for a pond not large enough for a British Native waterlily is Nymphaea odorata alba.

More detail on Waterlily Water Depths:

  • Each size of waterlily will grow in a different depth of water so make sure you take this into account when choosing which variety you want.
  • All waterlilies need to have the top of the basket placed below the potential ice level of the water by Winter.
  • Miniatures can ony have a maximum 15cm(6 inches) of water over the top of the 11cm/4inch basket.
  • Dwarf waterlilies will accept 25cm/10 inches of water over the 11cm/4inch basket.
  • Pond waterlilies are in 2 categories - those with <p>Suitable for shelf depth 23-44cm (approx 10-17”) below water surface</p> under the image (Medium) are less vigorous in spread and grow with  35-60cm/14-24inches of water over the 15cm/6inch basket. Large water lilies showing <p>Suitable for shelf depth 14-22cm (approx 6-9”)</p>  under the image can, eventually, reach a metre deep.

Additional Feed for additional growth:

  • Waterlilies will benefit from being fed twice a year. Once in early Spring and again mid-Summer.
  • Choose the XL Aquatic feed ball for larger waterlilies sent in 23cm/9inch round baskets - 1 each feed.
  • Use one Feed balls for Aquatic plants for smaller waterlilies sent in 11cm square baskets - 1 each feed.
  • You can also use these smaller feed balls in all your other flowering Pond Plants in 11cm baskets.
  • Or use 3 smaller Feed balls for Aquatic plants in the large 23cm baskets and 2 in the 15 cm baskets.
  • Push the Aquatic feed ball into the soil of the basket by the crown of the plant to give the flowering and growth a boost.
