Hello Jo
J How can I collect rainwater without it going stagnant? My
J waterbutt always goes green (the water, not the butt!) and
J has all sorts of nasty insects living in it, not nice...!
J Does it need to be out of the sun / lidded? Or can I add
J steriliser tablets, or something?
Just a tight fitting lid. Algae needs sunlight to live. Insects need
access to lay eggs. You can stop both with a lid.
Lids commonly sold at garden centres for the common sized butts, btw.
But tbh, green water with larvae in isn't going to hurt your
houseplants.
