Remember that soon Queen Bumble Bees will be searching for a nest site. Hedgehogs are emerging and needing food. Mason Bees will soon be Buzzing around and frogs and toads will be stirring up the water. There is so much you can do to help wildlife at this vulnerable time of year. We heard on the TV this morning that there is a movement to clean up our ponds, many of which are neglected and not just over this winter. The easiest way to clean up a pond or lake almost effortlessly is to drop in (how many depends upon the size of your pond) Mud Balls. These work with Effective Micro-organisms and continue to clear the pond of bad microbes and bacteria over a period of time.
Alternatively, and cheaper, Pond Magic, which is made organically from plant roots, will make your pond gin clear. Just add the required dose once a day for a week, then once a week thereafter. The required dose can be calculated by this LINK by putting in the measurements of your pond.
