One of the most significant things we’ve added to our garden in the eighteen years we have been here is the pond. It is very much a wildlife pond so no fish for us! Almost from day one we have been fascinated by the variety of species it sustains, from the bright flashes of blue and red damselflies to the more dramatic emergence of large dragonflies who leave their outer skins on the iris leaves as they prepare to take flight.
Then there are the dozens of pond skaters who dart around from spring to autumn, the waterboatmen doing backstroke across the length and the snails, lots of snails – wherever did they all come from? Of course there are frogs too and their tadpoles, and a colony of newts who hang suspended in the shadow of water lily pads.
In terms of planting, the pond is almost entirely ringed by marsh marigolds which I remember us first falling in love with in Iceland where they grow wild and in abundance alongside rivers and streams. Their deep golden yellow always looks stunning when the water surrounding them reflects a vivid blue sky. We also have iris and the water forget-me-not is extremely happy, as is the purple flowered pickerel which is really getting rather too big for its boots. All of these plants are very welcome as they are also incredibly popular with bees and hoverflies who appear to enjoy being by the water as much as we do on a hot summer’s day.
What is far less welcome is the pond weed, in particular the blanket weed which, for some reason this spring, has decided to launch a takeover of our pond. It began with the frogspawn. Whilst that may seem a very odd statement, I love frogspawn when it is newly laid or when you can see tiny tadpoles wriggling within the jelly cell, but I don’t like it as the tadpoles break out of it leaving a rather slimy gunge all over the surface of the pond. This gunge appears to attract the blanket weed. We normally use barley straw to combat blanket weed but perhaps we were too slow in getting it into the water this year? Or perhaps the weed was encouraged when the temperatures suddenly leapt from freezing to sweltering within a week back in April, but either way we were faced with unattractive pond soup.
Fortunately I found a bundle of barley straw in the back of the shed cupboard but we realised that it stood no chance without a little help from us. But which utensil to use? I tried the winding the weed around the stick approach but I think I would have been there all summer. John decided on the garden rake which worked reasonably well but was still slow progress. In the end he decided that there was nothing for it but to put on the pond gauntlets and plunge in up to elbow depth. Soon he had three piles of green, gungy weed around the pond, each having carefully been checked first for any inhabitants but also left overnight so that any shy creatures could creep out of their own accord. Although the pond looked horribly murky for an hour or so, it was surprisingly how quickly it cleared and it was great to be able to get a clear view of our newt colony swimming around. They didn’t seem too disappointed that some of their weed/food had been removed, in fact they almost seemed to appreciate being able to swim more freely.
As part of his delving into the deep, John also retried the pond pump and soon had a delightful trickle of water cascading little diamonds of water. Apparently moving water helps the barley straw to be active but it was also rather lovely on a really hot day just to sit and watch the water spilling over and reflecting the blue sky above. Time to just sit and stare.
