Monty Don warns anyone with garden slabs to do one job now

Monty Don has issued a warning to anyone with garden slabs. The Gardeners' World host said that slabs can be hazardous at this time of the year as they can become slippery.

Brick and stone paths can become dangerous due to the growth of moss and algae. Making your path safe is vital as the algae can build up if not treated.

But according to the gardening expert, there is one job you can do to make your slabs and paths safe. You will need to get hold of a pressure hose - which can be hired if you do not own one.

In his November blog, Monty recommended washing off the algae with a pressure hose. Then you should brush sharp sand over the brick or stone path, he said.

He said: "At this time of year brick and stone paths can be very slippery and dangerous. This is due to algae that grows on the surface, especially if wet and shaded and at this time of year they may stay wet and slippery for months.

"The best way to reduce the slipperiness is to wash off the algae with a pressure hose (which can be hired by the day). When this is done brush in sharp sand.

"If the path is brick or stone the porous surface will absorb some of the sand. A quicker - but still quite laborious - alternative is simply to work sand in with a stiff brush without the washing.

"Either way you have a very effective way of making a path safe without resorting to chemicals."
