Using geotextile membrane for weed prevention? – Your questions answered

Weeds are a problem in all gardens the pesky things get everywhere and take up a lot of a gardeners time. There are multiple ways to get rid of them but for larger areas there is nothing quite like using  geotextile to cut down your work load. There are different types of geotextile and in most cases people tend to use the woven geotextile membranes. This is incorrect the best type of geotextile for weeds is the non-woven types – and  let me tell you why……..

Non-woven geotextiles come in different GSM grades so can be used for varying degrees of weeds.

Non-woven geotextiles suppress weeds by inhibiting light on their own or in conjunction with gravel/chippings.

Non-woven geotextiles are not easily cut or damaged

Non-woven geotextiles allow water through so that sub layer so soil do not become staved over time. So if you want to inhibit weeds but use the area again for planting the soil will still be nutrient rich.

Non-woven 100GSm will stand up to small car loading.

don’t forget that at Spudulica we cut sizes for you – just buy the geotextile size you need and we will send it to you ready to go.
