There is no cure unfortunately. There's various chemicals that you could try, but I wouldn't waste the money. They'll never be the same again. If they've had it, dig out and replace with dwarf holly, dwarf Euonymus, Photinia "Little Red Robin", or other short growing evergreen.
Just seen a...
I'm not committing myself yet on this one, even though I should get it. I don't suppose you could take a photo from a little further back and a different angle, and of one or two of the others?
My friend's garden I built and look after. The two Acers in the foreground are Bloodgood and Sango Kaku which were there already, but had been "lollipopped" on a regular basis until we took over 5 years' ago and let them get on with it. There's also an Acer palmatum dissectum atropurpureum in...
It could be Bay, but also Portugese Laurel. Bay leaves aren't usually wavy around the edge, or particularly elongated.

Hoping I'm not teaching my Grandmother to suck eggs, but come the drier months, you'll need to water at least once a week, and a monthly feed would help too.
Your Tamarix will never look like a conventional tree. The nearest way to get it anything like a tree would be to just keep the main stem which looks like what the bottom arrow is pointing to. Cut all the other stems right down to the ground and cut back any side growth on the saved stem back...
I've got 3 packets of these;

Would you fancy trying to grow them for me? You can of course, keep a percentage of the plants...
I've got one called Emily McKenzie. It's a beautiful orange colour with a brown middle and the flowers are quite big. only grows to about 18", so doesn't droop around like Lucifer. It flowers a bit later in the year than most Crocosmias...
That's the stuff. Looks like you've done a good job. What I failed to mention on my original post is that you should shave the grass off and remove the cuttings before you scarify, but it looks like you did, or you've achieved the right result with what you've done if you didn't. As mentioned...
We would scarify our bowling greens as soon as the season finished, which was the end of September, beginning of October, so get going on it ASAP. This will give your lawn a few weeks to recover before the weather gets cold.
Don't just tickle your lawn. Go bananas on it, going over twice in...
Ensure the soil level before you lay the turf is 1" above the paver edging. This is so that when all is settled and established, the grass level is slightly above the edging and you can run the mower overlapping the pavers so all the grass is cut.
