I've spent weeks strimming and weeding a big area that will eventually be covered with weed barrier/stones, but until that day I just want the area kept clear of weeds/grass. After clearing it, I sprayed with Roundup, but when new weeds/grass started growing, I found out that Roundup only kills active plants. I read somewhere that Pathclear prevents germination for up to 3 months, so a week ago I resprayed the area with Pathclear, but weeds/grass haven't died off yet. Am I using the wrong weedkiller? I measured the water correctly so had the right mix.
Our back garden is paved with bricks and we cannot keep the weeds down. It has no drainage what so ever and when we remove the weeds they are back before we have finished whole area. we have tried weedkillers but to no avail. there is grass growing between the bricks aswell. What advice would you have to get rid of them once and for all. We have 2 dogs so have to be careful what spray.
Hi Gerry, we have a holiday home with small stones all around it. This is looking really bad with weeds. We have tried various weed killers, but with only very limited and short lived affect. Is there something we can use to kill all the variety of weeds and then seal the ground?Thanks
Gerry,We are laying a patio of about 100sqm and given its size are trying to keep price at reasonable level. Want to achieve the look of yellow sandstone paving and have seen dyded concrete paving slabs which look great but are worried about the colour fading over time (even though would seal it every 5 yrs). Wondered if you had any experience of how these concrete slabs age over time (colour wise). Maybe better off paying extra for natural sandstone?(double the price) Thanks .
Hi Gerry, when laying stepping stones (unconnected) from my patio to my shed through my lawn, do I need to use sand & cement as a subbase, sand or can i just lay directly on topsoil?
We have recently removed old brick planters and now have a blank canvas at the front of our house. We have an old cement sidewalk that goes around the side of the house that we need to cover up or redue. I am wonderng about a low wooden walkway and deck. Is it okay to have a deck at the front of the house as long as there are plants blocking the view from the street?Or would another type of walkway and patio be better. Thank you
i spend a lot of time cleaning moss between patio bricks. I wanted to use a chemical spray, but was told that sprays stain the bricks. Do you know if this is true, or what would you suggest?
want to gravel my front garden as it is too tiny for grass. No fence, just leads to pavement and communal parking. How do I do this? how far do I dig down and do i put a mulch down before gravel goes on. Much Appreciated.
Hi Gerry, i laid decorative gravel on top of weed proof fabric which covers soil about 18 months ago. I am finding that with wet weather and footfall (last year!) water is pooling in the gravel and some areas are sinking underfoot. Should I have put hardcore on soil first and compacted it before the weed proof fabric and gravel was put down ? A pic of garden under construction is on my profile. Go raibh mile maith agat
Ants have been excavating a vast cavern beneath my patio. Short of resorting to mass slaughter, which I am reluctant to do, have you any suggestions for discouraging them? Unfortunately they also invade my bedroom which is just beside.
Not a horticultural question but still a garden question. I have a patio of indian sandstone which is now quite stained with small black circular discrete marks, almost appearing like a fungus or lichen.The marks are quite random, some stones being affected and others not at all. Despite use of a proprietary patio cleaner and power hosing the stains remain. Have you any suggestions? The run-off is onto grass.Many thanks, Paula
