My front flower bed is being over run by Brunnera/perennial Forget-me-Nots - and I want to get rid of them.
They have a long tap root, which even if a smidgeon is left in the ground, will grow again.
Any ideas for a relatively painless way to "treat" them so that they just shrivel up ..............
The main resaon I hate them is that they have razor sharp leaves that can slice your hands open if you're not aware :(
Glyphosate is an excellent way to kill taprooted plants. Spray at the recommended dilution (about 1%) when the plant is in full growth in late spring. Deeply established plants and any pieces of root that you've already broken off may regrow and have to be sprayed again.
Taprooted plants can of course be killed by promptly removing new growth with as much root as you can get. After two or three goes round there will be nothing left capable of surviving.
