Gaps between flagstones

[strude]

I want to fill in the gaps between flagstones which are wide enough for weeds to constantly grow between. I have tried filling with sand but the weeds still grow through. Any suggestions please?

Hi strude,
If your not opposed to using weed killers in the garden, you could try using a systemic herbicide such as 'Glyphosate'. You can get in a handy spray-gun size for around a fiver that should keep the weeds away for most of the summer if applied in the spring. 'Round up' or 'Pathclear' are usually recommended. Good Luck Tbird+

Hi Strude,

Unfortunately no matter what you fill the gaps with, the weeds will still get through.

However you can give the gaps a good soaking with "Sodium Chlorate" before filling the gaps with a mixture of sand and cement 3:1. This will slow down the weeds coming through.

Sand and cement ?

use the water off your boiled potatoes.

Pour between the gaps, it kills all the weeds its too starchy i presume.

and no nasty chemicals !!
