Pond Plants Direct - A White Water Lily

April

By April, with the danger of frost now passed (hopefully!), submersible pumps for fountains and waterfalls can be safely reconnected. You should also test the nitrate and pH levels of your water and make any necessary adjustments. Blanket Weed Dredged From A Pond

It's a good idea to feed your containerised aquatic plants with specialist feed pellets. Don't use general purpose garden fertiliser, as this will upset the nitrogen cycle of your pond and in turn be harmful to fish and other wildlife.

Starting this month, you should look out for pond algae and blanket weed. Remove it as and when you see it as it will only flourish if left unchecked.

May

The start of this month is a good time to check your aquatic plants for aphids, mildew etc. Species particularly prone include Glyceria maxima / variegata, Lysimachia nummularia and most varieties of Primula.

Limit the spread of floating plants such as Lemna gibba (duckweed), Azola (water fern) etc. as these can soon takeover your pond. Also, keep an eye on your water levels. The warming temperatures can result in levels dropping by up to 5-7 cm per week. Remember to turn off your fountains and waterfalls on especially windy days as the diverted flow can quickly empty a small pond. Red Dragonfly

As now is the time for fish to spawn, make sure that the fry have access to a shallow area, safe from the attentions of adult fish.

Dragonflies and mayflies are something special to look out for this month. The larvae of these beautiful creatures live under the water (for as long as 5 years in the case of some dragonflies) feeding on small creatures passing by. They gradually climb out of the pond, leaving behind an empty larvae shaped husk, which can sometimes be seen still clinging to the stems of plants.

June

This is a month for sitting by your pond and enjoying all your hard work. However, if you want to keep on top of things, you can start by deadheading any plants that have already flowered.

Keep an eye out for newts, both the smooth and crested varieties. These shy creatures are just as beneficial as frogs and toads in terms of eating garden pests.

Try introducing the Planorbis corneus 'Great Ramshorn Snail' to your pond. This snail is identified by its French horn shaped flat shell, and is the only snail truly recommended for a pond.

Flowering Mysotis They remove algae and search the pond bed for food, but rarely attack the plants higher up in the pond. However, these snails are not recommended if you have large koi in your pond, as the snails would become a tasty (and expensive) snack.

If your plants are in full bloom then there is a good chance your algae will be too, so If green water has become a problem try fitting a UV filter system. These cannot guarantee to clear your water but they usually help.
