Lots of bulb weeds in newly laid turf
I recently got a landscape gardener to put in a new patio, clear the garden, create flower beds and lay new turf.
The garden was a bit like a jungle with lots of weeds. Here's a before picture:
Landscape gardener laid turf 3 weeks ago and I can see there are lots bulb weeds coming through the turf especially where 2 strips of turf meet. The lawn area is probably about 10m x 4m. I walked on the lawn for the first time yesterday since it was laid and I could feel the turf being very bumpy. The bumps are quite big and feel hard. I think these are created by the bulb weeds trying to grow under the turf which is lifting the turf up.
Here are some pictures from the lawn and flower beds:
There were couple of areas where it was really bad with big bunches of weed plants coming up through the gap between 2 turf strips. so last night I moved the turf bits to the side to expose the weeds and tried to dig out the weeds and bulbs. I managed to remove the leaves but don't think I got all the bulbs out. They seemed to be too deep and I didn't want to cause too much damage to the turf. I then poured a bit of hot water in to the soil where the weeds were (was careful not to pour them on to grass) as I read that hot water can kill weeds, added a bit of soil to cover the hole and then moved the turf back. I hope I haven't damaged the turf too much.
There are probably 10-20 weeds that I can see come through the turf but a lot more bumps (weeds still under the turf).
I don't know what to do. It's not possible to remove the weeds that's under the turf (but not in between 2 strips of turf) without having to dig out parts of the turf which will create holes.
I see lots of these weeds in flower beds but I can at least dig these out.
Obviously I am very annoyed at the situation. I don't think my landscape gardener used a weed killer when he prepared the ground. I did ask him at the time about a weed killer but he said 'they don't work'. However number of articles online about laying turf, seem to suggest using a glyphosate weed killer.
Also I saw lots of bulbs (presumably weeds) were on the ground before he laid turf and I'm not even sure he removed them before laying turf.
Is there anything I can do to get rid of these weeds without destroying the turf? What can I do about the bumps? (someone at work said use a roller).
Will I have to get it re-turfed? Perhaps I should ask the landscape gardener to do this!
thanks in advance for your input.
