Least wanted?
Couch Grass
Wiry, tough grass which invades most neighboring garden beds. Best removed with a garden fork, which you drive into the ground below the leaves and pry up to get the white, wiry rhizome.
Do not compost! Put in the bin or cook in a wheelie bin with moisture so it rots and dies.
The best way to get rid of a large area of couch grass is to Sheet Mulch it. Not with plastic weed matting, remember? Weed matting sux!
Onion Weed
Onion weed is has green strappy leaves growing from a mainly white bulb which gives off an onion smell when crushed. If you don’t have time to dig them out, please pick off the flower so it doesn’t go to seed. Do not try to pull the plant out of the ground, or shake excess dirt back off into the hole or compost. The small bulbettes tend to pull away from the mother plant when pulled, which leaves more bulbs in the ground that will happily grow. remove the entire clump of soil and put in a green bin, regular bin or heat treat in a black bin for an extended period. spray the vacant hole with vinegar for good measure.
Do not compost! Put in the bin or cook in a wheelie bin with moisture so it rots and dies.
Tradescantia
The weed formerly known as “Wandering Jew”, this is easy to remove by simply pulling out and leaving in a pile in the sun to dry out. Small amounts may grow back, but with a little persistence it is easy to eradicate.
It is often confused with the edible Australian Native ground cover, Commelina which has blue flowers rather than white.
This can be piled up in the sun to die.
