I'm going to guess lack of water while it establishes itself. You
don't
say
where you live but here in the SW we've had long dry spells, even
if they
weren't all hot, too. We've also had some strong winds and the
two
conditions combined are dangerous to many plants.

I'm in NW London. We've had some very hot weather recently, but
rain on
and off too. I had been neglecting the front garden (once a week
water - if
that!), but am giving it a really good soaking each weekend now and
about 3
times during the week it gets a quick blast.

"Quick blasts" of watering almost certainly do more harm than good,
because they encourage roots to grow near the surface, so the more you
give quick blasts, the more quick blasts the plant requires.
