A year of the pond

It’s been about a year since we restored our pond and I’d like to share with you just how well it has developed in such a short time. I expected it to attract wildlife, but I didn’t expect it to happen so quickly or for it to be so easy.

The first real signs of life were a couple of frogs we discovered on the patio in mid March. We were excited and expected to see frogspawn the following morning, however it was a few weeks before the first batch arrived. My daughter had made checking for frogspawn part of her morning routine before school, and on 2nd April she came running in screaming with excitement.

That same day we found another two frogs paired up on the patio, and the next morning before breakfast we discovered that our pond was teaming with amphibians all fighting to pass on their genes – some more successfully than others. In total I counted 30 individuals, although I am pretty sure there were more; the pond was so busy it was difficult to count them all. When all the activity had died down, the spawn eventually covered a third of the pond edge.

One problem we did have with this influx of frogs is that the crows which live in the trees at the end of the garden suddenly had easy dinners and unfortunately a few frogs didn’t quite make it. So in an attempt to keep the frogs safe, we built a makeshift scarecrow which seemed to work. One the 1st May we spotted our first tadpoles.

While the tadpoles matured and eventually left the pond, the vegetation which I had planted in August last year was beginning to grow and would eventually provide cover for the emerging froglets, as well as supplying nectar for foraging bees and other insects.

I’ve been asked before what plants work well to plant around the edge of ponds, and I always respond with native species such as those below. I think we have such a beautiful range of native wetland species that there is no need for any others – but this is of course my preference, and I am sure there are many other marginal plants out there. One thing to remember though is that some aquatic plants which are introduced can become invasive if they escape into the wild such as parrot’s feather Myriophyllum aquaticum which is now banned in the UK as well as four others. If you do grow non-native aquatic plants, do not dump them into any wild waterways.

One problem I have had with the pond is the thick blanket of duckweed. A little duckweed is fine, and is probably a good thing, but unfortunately the nutrient levels were increased in our pond after my daughter ‘fed’ the tadpoles about 50 slugs and snails! I noticed that the tadpoles were coming up for air a lot more than they should one day so I began clearing the duckweed using a large holed tennis racket, carefully picking out any creatures such as rat-tailed larvae and water louse. I had to do this every other week or so, as and when the duckweed regrew. I also added in some oxygenating hornwort to help the tadpoles.

One day when clearing out the duckweed I made a discovery which made my day. I had caught a newt! A very large, male smooth newt Lissotriton vulgaris. Part of me had hoped he was a great crested newt, but I was still happy to have found another new resident of the pond.

Having a pond in the garden is great for curious kids. My daughter loves pond dipping with me and we have discovered large dragonfly and damselfly larvae, rotifers, may fly larvae, small diving beetles, water louse, blood worms, pond skaters and most recently, a newt eft which shows that the frogs aren’t the only ones breeding in the pond. It is worth noting that when removing duckweed, to also check for newt eggs too.

The pond is also visited by different Odonata – the family to which dragonflies and damselflies belong. Last year just shortly after the pond was restored we saw dragonflies laying their eggs in the water. This year, we have seen a few different species of Odonata including the large red damselflies Pyrrhosoma nymphula and the southern hawker Aeshna cyanea dragonfly.

I am sure that this is just a fraction of the wildlife which has benefitted from our pond. The foxes come and drink from it each night and the bats feast on the emerging midges above the water. The pond provides nourishment, a home, and a place to breed for creatures large and small and I look forward to seeing what the next surprise will be.

If you have a pond in your garden, I’d love to hear what wildlife it has attracted. Comment below or get in touch through twitter or facebook.

The Pond – Part 1: Creating a home for the frogs

I’m going to kick this blog off with a post about my favourite part of the garden; the pond. It’s my favourite for many reasons but the main two are that it didn’t cost us anything to install and it attracts so much wildlife to the garden. I really think that having a pond, no matter how small makes such a difference if you are aiming to attract wildlife.

When we viewed the house last year we were sold when we saw the garden and was told that we were free to do as we like with it (within reason of course!). It was a blank canvas – an overgrown large patch of grass with the woodland behind our house encroaching into the back part of the garden. Perfect.

We moved in and I was eager to get going. It was June, it was hot and I was pregnant so progress was slow. It took us a while to get around to mowing the lawn as we had to purchase a petrol brushcutter. The grass was so long the flymo couldn’t handle it. Standing by the edge of the garden I noticed that the ground below my feet was springy and squelched. It looked like the rest of the lawn, but something felt different. After a bit of investigating, we found a small pre-formed pond which had been filled with rocks and bricks with grass growing over the top. It had been abandoned and we decided to bring it back to life.

I emptied the pond of bricks, rocks and some of the mud, piling up the soil on the bank for the marginal plants. There was water in the pond still so I left a lot of the mud there thinking that perhaps some of the creatures had survived, especially as i found so many frogs and toads hiding out under the rocks. Also, by leaving in some mud it added an instant pond bed. I wondered whether it would be too rich in nutrients which could cause problems later on and ideally I should have carried out a nutrient test, but I took a chance and left it in (mainly because pulling all the bricks out had worn me out and I was eager to see it finished!).

Unfortunately I had to stop anyway because I managed to put a hole in the side of the pond with my spade. Tip – be careful when using tools to dig or clear a pond, especially if it is made using pond liner – seems obvious doesn’t it! I ordered some pond putty and left the pond alone for a few days.

With the hole fixed, it was time to add some structures for all the frogs and toads to get in and out and to hide in. I used the rocks to build up one side of the pond and added a couple of logs. Ideally a wildlife pond should have a shallow end or a gradual transition from the bank to the pond. This is achievable with a pond-liner but not as easy with a preformed pond. It’s also about working with what you have too when renting.

We were lucky to have a beautiful large fern growing next to the pond. My partner has a good eye for aesthetics and so to compliment the fern he suggested we piled up more rocks around the edge of the pond and under the fern. By this point, we already had a resident living in the pond. A large fat frog had moved in and every now and then popped his head above the water to check out his new digs.

Finally, the last stage was to add the plants. I planted lesser spearwort Ranunculus flammula, soft rush Juncus effusus, and purple loosestrife Lythrum salicaria in the pond itself in basket planters, and ivy-leaved duckweed Lemna trisulca and a water soldier Stratoites aloides in the middle.

Around the edge I planted a few garden plants I brought with us from our old house including purple toadflax Linaria purpurea and the following native marginal plants:

  • silverweed Argentina anserina
  • ragged robin Silene flos-cuculi
  • water figwort Scrophularia auriculata
  • teasel Dipsacus fillonum
  • marsh ragwort Senecio aquaticus
  • marsh woundwort Stachys palustris
  • rosebay willowherb Chamerion angustifolium – seeds
  • great willowherb Epilobium hirsutum – seeds
  • hemp agrimony Eupatorium cannabinum – seeds
  • Common fleabane Pulicaria dysenterica – seeds.

One the plants were in, it was just a case of letting nature take over. We were surprised just how quickly the wildlife found it. The foxes would come to drink from it each evening, dragonflies laid their eggs in it and bats came to feed on the midges emerging from it. By Autumn, the pond had established and we couldn’t wait to see what arrived in spring, but that’s a whole other blog post.
