Overwintering container grown Euphorbia

I've just bought three beautiful euphorbias "Tasmanian Tiger" to grow in large containers. Can anyone advise me on the best way (hopefully not too difficult) to see them through the winter?

 

Yes Jane

They are not too difficult. They are hardy, tough, evergreen and adaptable. They are very attractive in my opinion too

I have only grown them in the open ground but I would use john innes number 3 compost and keep them fairly dry esp over winter. They do not like being moved too often either. You can grow them in sun or partial shade.....in partial shade I think their variegated foliage shows up best.
I would also put a few chippings down after planting......to reflect the foliage, stabilise moisture levels and simply look good

When they flower remove the flowered stem.....in mid spring.

Be aware, all euphorbias have a toxic, caustic sap so be careful when cutting them

 

Thanks Verdun. I wasn't sure whether they would be hardy, having read they need winter protection. Temperatures here have been known to drop to -11. I have all three in containers near a wall and south facing so I'm hoping that will give them some protection.

Like you suggested, I used john innes number 3 compost. And horticultural grit to top dress them. When temperatures start to plummet I think I'll add bark chippings as extra protection.

I hope I do get a chance to see them flower. Fingers crossed this will be a mild winter.

 

No, not bark Jane. If you are concerned when temps drop very low cover with a fleece

 

Thank you again Verdun. Yes I can see the wisdom in that. Will do.
