Q. We treated the lawn with a weed and feed mix earlier in the year but now we have weeds popping up again. What can we do, should we weed and feed again?
A. It would be better to spot weed, preferably digging them out and pushing the grass back down or use a spot weedkiller such as Westland Resolva lawn weed killer which targets only broad-leaved weeds such as clover, buttercup and dandelions, killing the root but not the grass.
