Hi, we had a new turf put down in november 2015. Prior to the new turf there was some sort of poison ivy weed all over the garden. We killed the ivy off or so we thought prior to having a landscaper come and lay the turf and pave the garden. At first in the winter the turf looked great, since the warmer months have come I have noticed the same ivy sprouting up in various places on the turf. ?
I have no idea how to get rid of this without killing or damaging the turf.
Can anyone help please. I've attached a few pictures, prior to mowing the lawn.
Thanks

You can get it in gel form where you can, if you have enough patience, paint it on the individual leaves.
Mowing regularly so that the leaves never get chance to photosynthesise will go a long way to discouraging it but its a long job.

Oh dear. The good news is, its not poisonous (we don't have poison ivy in the UK). The bad news is, it looks like Convulvulus arvensis, one of the bindweeds, and they are difficult to eradicate, particularly in cultivated areas. Info in the link below

The usual procedure is to insert bamboo canes where it's growing, let it twine to the top, then spray with glyphosate, but that's not really an option when its growing in a lawn, too much risk of spray drift onto the grass, so probably all you can do is mow it, but be sure to collect up the clippings and don't allow flowers to form, to prevent seeding.
You can use the bamboo cane and glyphosate treatment if it grows in borders, but protect any surrounding plants from the spray. If you don't have glyphosate already, you might want to invest in a plentiful supply - it's likely to be withdrawn in the near future, and use glyphosate concentrate, mix it up yourself and use in a spray rather than buying Roundup.
