In my mother's new house there are a lot of coarse sedge / grass plants
that are taking over the garden. We have tried trimming them off at
ground level and sprinkling with sodium chlorate, but they are growing
again within days.

Is there an easy way of getting rid of them without poisoning the soil
around?

They are difficult to dig out and leave a big hole.

thanks

That's precisely wrong. Sodium chlorate will kill annual weeds in
low doses, and kill everything for a fairly long period in high ones.
It is definitely a 'soil poison'.

You could try glyphosate (well diluted), but I don't know how sensitive
they are - grass is very sensitive.

They seem to be immune :~( Best bet is to allways cut the seed spikes off
when ever seen and fork the clumps out, but the OP is in for a battle

If it is giant sedge, then digging out is the best bet, even if it's difficult to do. If you then bruise any new growth and spray it with Roundup, it will slowly give up the ghost.
