You've posted photos of your garden--I think it's lovely. Ours is more properly what we in the US call a "yard", because it's mostly grass with the occasional tree. The service comes with giant riding mowers and makes the grass short, and if I ask them they will do "cleanup" which is things like spraying for weeds, and removing stray tree seedlings (elms and boxwoods are extremely prolific), but any non-raspberry foliage in the raspberry patch and non-mint in the mint patch is my problem. Which is why the raspberries are currently accompanied by lots of vigorous tree seedlings at the moment.
