I have been lurking here for a few weeks and would now like to tap your
not inconsiderable collective knowlege.

I have two problem weeds, one in each of my two lawns. Both have been
treated with Verdone and a spray on spot weeder with no effect. The
first is

This one has purple flowers looking somewhat like clover

Self-heal. Dig it up, religiously. That's not too hard, as its
flowers stand out well. It's very attractive, and a functional
lawn plant, but is much darker than grass.

and the second is

The foliage is purple and seems to shed water - it spreads readily.

I appreciate that one answer is to dig it all up and re-seed but the
second covers a considerable area and appears to spread from the
smallest fragment

Oxalis (sorrel). I am not sure which. Try nuclear weapons, or
glyphosate and often.



Agree the second one is Oxalis and a nuclear bomb would just spread the seed
over the whole country!

I have it here, it seeds into the front garden where I constantly try to
control it, it seeds into pots where I try to pull it out, it seeds into
paving where I use a flame wand to control it, I try not to let it seed but
it hides under other plants. Luckily it does not appear to like our grass.
If you get it in a packed greenhouse OMG total repotting job.

BTW don't try composting it, dump it.
