I have an increasing problem with Singapore daisy. I'm on a largish residential block. I moved in April this year, and had a landscaper clear all the vegetation (apart from the big trees) and mulch heavily. The Singapore daisy is creeping through the fence line from a neighbours place, and looks like it will set flower soon. So I have some questions - Friend or foe? Is there ANY use for this stuff in a permaculture system and I should therefore tolerate it, or is it an outright pest and needs to go? How to eradicate it? I've started pulling it out by hand and putting it in the rubbish bin, but 1. it is a pity to loose organic matter from my system and 2. it feels like it grows faster than I can pull it out. I'm wondering if I can make a compost tea out of it and pour it back onto the rest undiluted. I think it was Purple Pear who suggested the same for comfrey? Would that work? Could I use it as a dilute tea elsewhere in the garden? And once it has sat and stewed for a few weeks would it then be safe to toss in the compost heap without fear that I'll spread it further? What about solarizing it? I gather you just put it into a black plastic rubbish bag and leave it sit in the the sun for a few weeks. Would that make it safe to go in the compost?
