Have you used the feed on all of them ? I'm wondering if maybe the roots or leaves have been scorched by it. From memory l think it was 70g per square metre application and then water in?
I agree with @Papi Jo that it looks like a lack of watering. The fact that the rest ov the garden is looking lush is neither here nor there ... new plants need much more watering than established ones.

Those little plants wouldn’t have been much good so close to the hydrangea anyway, hydrangeas are big plants, they take all the water up from the surrounding area.

But the Box have been there for a year and a half and were fine until we arrived back from holiday to find them like this. I'll scoop up the slow release feed tomorrow and see what happens. Is there anything else that would make a nice small neat hedge to form a circle edge around my beds if they don't work out?
The Choiysa have been watered well because the nematodes have been applied and you have to keep the soil moist for them to work. They have been planted in the area where we had a lot of adults, but I couldn't see grubs digging around. I'll pull one up tomorrow and look in the roots.
If they’re happening to plants that have been planted in last few years it could be how you prepare the soil for planting. What is your soil like?
Two common issues are digging holes in heavy and un-loosened surround soil and putting some compost in the hole and covering them. The other is not breaking down the surrounding soil and planting in pot plants that haven’t had the roots teased out enough.
In time the plants don’t thrive and in hot dry weather they detach from the surrounding soil and dry out.
For an alternative plant as a low edging for the edge of your borders, take a look at Euonymus Fortunei.
The Choisya were in raised beds with brought in top soil and compost. They just pulled out really easily but no sign of weevil grubs or adult nibble signs.
I've pulled up several box plants, they were harded to dig up. But seemed dead as no green. The ones that look to be doing ok, about 9 of them, I've left. They have lots of new growth. They were planted in a new bed but the whole of the garden was dug up 3 years ago and land drains inserted because it was very boggy so soil not overly compacted. I'll see how they go.
