Your pond in the hot weather - which is due to continue!

How much water does a pond lose in hot weather?

• In normal summer months, the sun can cause around 2 to 3 cm of water loss from your pond in a week.
• Check for water loss from your pond or container pond due to water evaporation from the surface.
• This will be more in the current hot temperatures.
• And the plants will lose more through their leaves too.

You need to check for water loss and top up your pond in hot weather:

• Ideally use rainwater from a water butt to avoid adding nutrients or chlorine to the pond water.
• If you need to use tap water to top up then add Chlorine Guard to reduce the effect of the chlorine.
• Add Chlorine Guard every time you add tap water to the pond & stir the water.
• This is an environmentally friendly product based on seaweed extracts that is safe for fish, pets and wildlife.
• Excessive water loss will cause distress to fish in your pond.
• Wildlife in the top shelf area will become exposed to predators as the water level falls.
• Pond plants on the shelf will suffer or die if their roots cannot reach water.
• Flowering marginal plants & waterlilies will be in overdrive in the hot weather so boost with a feed ball for continued growth & flowering
• Exposed areas of pond liners are at risk of splitting due to sun damage.

Solutions:

• Add more waterlilies or Frogbit to your pond so their leaves cover more of the surface area to give shade leaving less open water for evaporation.
• Cut back Iris plant foliage after flowering to 15cm/6" tall above usual water level.
• Tall foliage loses a lot of water so reducing the leaf height reduces the load on the pond's limited water resources.
• Leave a good 15cm/6" stem height though for dragonflies to climb up to leave the pond.

Other hot weather issues:

• Water features and filters may block up with excess algae/blanketweed that grows faster in the heat.
• Your pipework could crack and leak when exposed to the sun if it is not made from uv stabilised material.
• Moving water features may run out of water causing the pump to run dry and burn out.
• Your pond liner may be punctured by animal and pet claws as they try to drink from the lower water in the pond.

Solutions:

• Treat the pond more frequently in hot weather with liquid Barley Bio Algae Control - twice weekly if necessary.
• Do not increase each dose.
• This is a safe, organic method that works better with more frequent dosing.
• Make sure your Barleystraw minibale is still active and not going black quicker than usual in the heat.
• Add a new one if it is & remember to remove the old one in a month.
• Back up the minibale treatment in the short term with Barley Bio as well during the heat wave.
• Clean the filter and pump more frequently. Use old pond water (not tap water) to clean it to keep all your beneficial bacteria.
• Use Pond Revive to boost the beneficial bacteria levels in your pond water - another safe, organic product.
• If you find a hole/split in the liner - patch it with a piece of liner fixed with waterproof adhesive.
