SA Earthworms
Hi to all the ex-pat Japies and my fellow SA gardeners
Hope you can help with the following:
I garden on the Southern tip of the Cape Peninsula near Simonstown. My indigenous garden is high on the slopes of Elsies Peak overlooking False Bay.
I am thinking of introducing earthworms into my garden as the soil is poor and very sandy (although heavily mulched). I want to try and improve it and increase the water retention as the soil (sand) is hydrophobic. Although the conditions are not suited for earthworms I want to start creating pockets of suitable soil for them and allow them to 'colonise' the garden(1200 sqm).
However, I do not want to introduce worms into the garden until I know that they will be 100% beneficial and ecologically acceptable as the region is sensitive and under stress due to alien infestation (Wattle,Hakea, Argentinean Ant etc). The information on the 'net is overwhelmingly US based and does not examine the ecological impact that the introduction of exotic earthworms might have on a region.
I have been unable to find a SA based supplier of worms that could advise me. Increasingly, it seems that I will have to order worm capsules from the US.
My questions are as follows:
>> Is the Eisenia hortensis or the European Nightcrawler the same earthworm that we find in SA? Similarly, is Eisenia foetida or the Redworm found in SA?
>> If not, would you know where I could find the local variety? Or how I could breed sufficient stock?
It must seem strange to seek help on an US site but I am hoping to run into a worm lover who has done some research and/or has experience in this matter or could refer me to an academic journal or site. I have had very little luck locally as vermicomposting does not seem to be popular or, at least, has a very low profile. Even the National Botanical Institute has been of little assistance.
Any other general info would be appreciated.
Regards
Charl
PS I will post this on the vermicomposting site also.
