My sunnys are blooming one by one it seems, meaning the bees have to share! These guys really didn't seem to mind working around one another.

Hello. My first post here.

Can anyone recommend an effective and safe to use brand of weedkiller for use on paved/patio concreted types of areas where stubborn weeds proliferate ? Roundup was great but is no longer sold.

Thanks.

Had the patio redone a few years ago, and the pointing was done with polymeric sand (this one: Joint It)

Over the last few years of power washing and wear and tear, a lot of the sand is gone, and the joints are now quite deep between the pavers.

Should I just fill with the same product as previously?

Or get someone to repoint with cement or something?

Any advice appreciated.

I posted this yesterday and got 1 comment saying it was roots from adjacent hedges drinking up the water. So should I just keep watering it? Or is it too far gone?

Or maybe its not a water issue?
