Rookie error!

I'm in a new build so starting the garden from scratch and now the plants have grown I can see I've committed a rookie error by planting some plants too close.
Can you advise when is it best to move plants around the garden?

Also just another quick question....my spring primulas are flowering again. Is that normal?

Thanks

p.s. 1st post so hope I've done it correctly!

 

Hi @Jaki
It depends what the plants are. Hardy perennials that have finished flowering can be moved now but some are autumn flowering, like Michaelmas Daisies for example, so I'd leave those until later in the year or spring.
Cut the old stems off when you transplant them.

Deciduous shrubs should be moved after the leaves have fallen.

Sometimes spring flowering plants do flower later in the year, several are doing it in my garden now - Primulas, Weigela, Bergenia. I just enjoy the bonus of some extra flowers

 

Thanks Micheal.
They're lupins mainly, lavender and an acanthus which I didn't realise how big it would grow!
Some lupins are still flowering so I will wait but I've already trimmed back the lavender (as I read now was the time to do that).
The acanthus hasn't flowered (yet?) but has grown a lot. I only planted that this spring and it was a small one.

Yes I was thrilled when I saw flowers again on the primula. They'd put such a great show on in the spring I wondered where they've got their new energy from! They really do give a lot for the money.

Yes leave the Lupins until they die back ...
I've never grown Acanthus so can't be of help with that.

 

Not sure but I think Acanthus can be a suckering plant once you start chopping up the roots, so best to get it moved this winter to somewhere where it can stay for good.

 

Cheers Pete....I've got a spot lined up for it that should take it full grown!

 

Lupins don't like being moved. Best to leave them and move something else.

 

Oh..right Jocko! I'll look again and do a rethink.

 

I've moved a lot of my acanthus...to the compost bin....AGAIN!
Can be a bit of a thug if the soil is to their liking, just wish I could grow lupins(or slug food as it's called in my garden)

 

Sounds ideal for the place I have in mind then flounder! It needs a thug! and a statement plant.
I'd one in Spain and quite liked it...but it didn't grow too big. However it threw out seeds like I don't know what! Kept all the neighbours in plants! They probably hated me after they'd matured and started doing the same!!
There I had to put it north facing for it to do well....but here they seem to like sun? Is that right?

 

Established plants may be divided in Spring to reduce the size and/or increase their numbers.They have a central tap root, which should remain undisturbed, but a section of the outer plant can be severed and planted elsewhere immediately (in )Spring. These will remain true in colour, whereas seeds taken may not. Also cuttings may be taken from the new growth as it reappears next year.
