Apologies in advance if this question has been addressed before, however, we and our neighgours have a massive problem with Asparagus sprengeri (asparagus fern). I am literally pulling out 1000s of seedlings at the moment due to the constant wet conditions here. We both have large patches of mature plants on our properties, ours is about 1/2 acre in size, growing in amongst bushland. I have tried various poisons before, without success, including extremely high doses of glyphosate. I've been reading some articles which advise that a "1 percent solution of glyphosate to 0.25 percent surfactant", does kill the plant. Does this mean to (nearly) 10 litres of water I add 100 ml of glyphosate and 25 mls of surfactant? The amount just seems so little! Any suggestions would be greatly appreciated, but removing the numerous, larger plants by hand is a daunting task to say the least. :-?
