Yes - sadly my garden has one section governed by Marestail - and I use the word 'governed' advisedly. Last week my gardener was rather pleased with himself when he said he had removed every piece. I went into the garden this morning and removed at least a hundred 'tails' which had appeared since then - and that is just in the bit I can manage to weed.
It is actually a rather pretty weed (I believe one of the professional gardeners on the radio called it a 'prehistoric weed, impossible to eradicate'), so I am learning to live with it and embrace it. I keep telling myself that it is no worse than ground elder or couch grass - but not sure I believe it.
It is possible to clear the area and get a licensed gardener to spray the spot with glyphosphate (you need a licence to use it) but it comes back again the next year - it is indestructible.
Other than that my garden is coming along nicely. My gardener planted half a dozen evergreen shrubs for me last week and a friend left a bucket load of bits from her garden yesterday. At present they are sitting in the shade, waiting for my gardener to call. Most need to go in at the top of the plot, where I dare not venture: I am not sure-footed enough.
Beautiful wall to wall sunshine here today and warm with it. Washing dry on the line outside - next job is to iron it. (Yes I am one of those ancients who still knows how to wield an iron).
