After the recent spell of hot weather, David Coton was glad to see the recent rain freshening up the Garden Centre and he has these suggestions for some of the jobs that need to be done during August.
All ponds need a ﬁltration system to keep the water clean, clear and healthy. As Dan Everton points out, stocking levels of fish are much higher in a garden pond than in the wild and, without a ﬁlter, impurities accumulate to create a toxic environment.
Mechanical and biological filters, together with UV clarifiers, will cleanse the water to create the best possible environment to encourage a thriving population of fish and plant life.
For ponds up to 10,000 litres, box filters are the best choice, they may contain a clarifier and can be biological or alternatively mecanical. If you prefer, some boxes can be hidden underground or you might choose a filter that can be immersed.
Pressurised units allow you the option of powering a waterfall or fountain and more expensive filters feature advanced technology, can handle larger volumes of water or offer functions that are labour saving and can significantly reduce running costs. These include self-cleaning systems and power saving devices that enable the UV filter to switch off when not required.
When choosing a filter, consider what is most appropriate for your particular requirements. Follow the manufacturer’s recommendations on the filter’s capacity and the volume of water it can process. Remember that water should be circulated at least once every two hours i.e. a 2000 litre pond will need a filter that generates a flow of 1000 litres per hour.
Don’t forget that if you have fish, take into account how many and how large they are, as this can dramatically affect the specification that is required, as can factors such as whether you want the clean water to be pumped to fountains or other ornaments.
Also think about practicalities such as the ease of maintenance, perhaps a self-cleaning system is preferable. Running costs must also be considered, both in terms of the amount of power required and the durability and longevity of the product parts.
There is no doubt the range of pond filters on the market is daunting and can be confusing. Basic facts such as the volume of water, number of fish etc are vital components in making a decision, the rest is probably personal choice, preferably reinforced by the advice of a specialist retailer.
David Coton was recently invited to the exclusive launch of Grange's new products for 2018, the result of significant investment that the garden structures and fencing firm have received from their Polish parent company.
David Coton suggests that there are plenty of gardening jobs that need to be done in November, from why you shouldn't throw away your fallen leaves to how to take care of your vegetable patch.
In October, David Coton is getting the garden prepared for the onset of colder weather but, at the same time, the arrival of spring bulbs in the garden centre is a reminder that you should also now be planning ahead for next year.
At GLEE this year David Coton visited the VegTrug stand to find out how their specially designed space saving planters can encourage us to grow more of our own food without the use of pesticides.
