Windy weather one day and hot weather the next.
Four seasons in one week. This weather combination can have a real effect on plant establishment with water being taken from the leaves on a windy day faster than can be replaced.
If you have planted any evergeen shrubs / hedging / trees in the last 3 months then don't forget to water them thoroughly.
Check plants in pots have not dried out and give a thorough soak.
