Please help a gardening incompetent.

I have a very small (20ft by 40ft) garden. It has a patch of lawn in the middle and beds round the edge. At the moment, the beds are all full of weeds - mostly sea spinach. I have some wildly overgrown tamarisks and a terrace that's also weedy with grass growing between some of the tiles. It is in a very inhospitable place on the edge of a tidal estuary - lots of wind and occasional floods of brackish water. What can I do to make it less depressing? Can I kill the sea spinach with some sort of weed killer? I don't aprove of adding chemicals to the environment, but I'm desperate!

a good list of weeds and how to deal with them down the right hand side - no mention of sea spinach, might it be called something else?

I think glyphosate will kill all weeds and is not too bad for the environment (doesn't leave a residue)

Sea shinach is what my mum calls it. It looks just liek ordinary spinach any tougher and more evil

Can I do it now, ib, or is it too late in the year?

I would think so, you should be able to clear the beds for Spring planting. I think you can use glyphosate any time provided the plant you want to kill is not dormant.
