Hi Steve. If you've prepared the ground well before planting they shouldn't really need anything more just now. A lot depends on the conditions where you've planted them .You could give them a sprinkling of general fertiliser of your choice if you didn't do that at the time. Blood, fish and bone is my personal favourite, but use whatever you prefer. Just make sure they don't dry out if you're having hot weather but don't drown them either! A mulch after watering is beneficial to preserve moisture in hot dry weather. Bigger hedging plants often take longer to establish than smaller ones so you could cut them back a bit if they look like they're struggling at all.
Deborah - I know this is probably too late for a reply but yes - I'd cut them back a good bit if you haven't already done that. The weather conditions, the site and the time of year you planted would have made it difficult for them to establish well. As I said to Steve- bigger plants take longer to establish anyway. Cutting them back will encourage more growth lower down.
