Lift them gently and transfer them to pots with fresh compost. As they are newly planted it should be fine. Try not to damage the roots when you lift them and don't let them dry out. The border looks very pretty at the moment, but looking at the selection you have there perhaps you may have planted them without allowing for how big they will grow, so this would be a good opportunity to put that right - it is horrid to have to take out large ones just because they have got too big. If you still have the labels look up height and spread at maturity for each one on Google. If the labels are lost anyone on here will be happy to help.

I agree with Steragram.
I would read up on how big your plants will get, as yes, they are way too close as they will spread out. I have made the same mistake in my planting in the past LOL.

I agree too.Less is more in the long run..It might look sparse for a while,but in a couple of years,you will be glad you planted further apart,if you decide to follow advice..They will be just fine,if you do as Steragram suggests..

If you are worried about it looking sparse grow annuals or cheap perennials between the shrubs. Welcome to GOY.
