First step would be to well water the ground you are removing them from. The wet earth makes it easier to dig any plant out with minimal root breakage

Really interesting comments read on this!

big root ball, wet hessian, lots of watering in, and a little seasol and chook poop too

prepare them first by feeding them up on seasol

The first place I would go for advice is the local nursery! They are usually so helpful when it comes to anything plant related! Hope it all went well for you!

I hope everything worked out for you.

there are some good comments here

Some good advice there below.

I hope it worked well for you!

I was going to suggest Seasol but LIZ007 have given the whole process

i hope it worked out

Hope you managed to successfully move your hedge

Did you have success with your move?

What did you end up doing?

I hope you found out a good way to transport plants

Okay cut back. Over night. Soak leave hose running slowly. Take as much soil as you can. When you do dg out to transplant. Please use a good sesol. Okay go to Woolworths or a garden shop and buy to stop plants from going into shock… Yes plants go into shock… It’s a bad time to move them as its there growing season but it can be done… So you have big holes dug. Ready for the plant. Fill will water. Transfer you plant. Put good soil back around not clay that you might of dug out of your hole. So you might need to buy a few bags … Now fill in around plants and water in with the. Water. And anti stress. Sesol. Mix. Good luck….

Definitely prune, and try to take as much soil as possible, even if you need to fill in large holes from where you are taking them from.

thanks for the useful info

Have a good prune, it will depend on the type of hedge but most can withstand a fair amount of cutting back, then dig out as much of the root system as possible and wrap the exposed roots in moist hession. Prepare your new spot carefully by filling the hole with water and a good handful of slow release fertiliser. It may be wise to pot up some cuttings too just incase the move doesn’t go too well, it will ultimately depend on the plant type. Also try and find a place in which conditions (sunlight, wind exposure etc) are similar!

a lot of useful tips and information Can be handy for others too in the same situation
