At the moment the weather is warm and wet and the plants are loving it so I think you will be OK. It's not as if we are having a scorching hot summer when you would worry about newly planted items.

I agree. To give them the best chance I would be inclined to cut down the top growth a bit and water well for a few weeks.

Dreeny, I note you are in Herts, where the weather's much the same as it is here in west London. I wouldn't recommend moving those plants now unless they're under 3 years old, and you can guarantee you'll be able to soak them thoroughly every 4 days with a sprinkler for at least an hour at a time. If they're over 3 years old, wait till they're dormant in late autumn, early winter.

Take the largest root ball you can and then water, water, water. If they are small you should be OK.

I think it would be wise to leave untill the autumn, not worth risking loseing them, autumn is not to far away and what you could do is get all the new holes dug now, get some nice compost/leafmould ready and it will be less of a chore come the time.

Thankyou to everone who replied to my question. I suppose deep down that leaving until the autumn has to be abided by. However, I am pleased to receive all the encouraging remarks.
