Hey,

Just thought I'd ask a question, here in the UK, north east, just bought about 12 perennials and planted them into 2 wooden boxes for the garden, thing is we are bout to experience some cold ass weather, snow and frost for the next week or so, I called the garden center where I bought them from and they told me that they would be fine outside as they need to get "hardy" for the winter.

I forgot to ask if they had them out side as they were inside when I purchased them...

With them being new and freshly planted I don't want the weather to kill them off or damage them if the temperature falls below freezing for a few days, even a week?

What you think?

Should I bring them indoors until this cold snap is out the way, I just don't want them to die.

Thanks

I saw in the news that the UK is expecting temperatures possibly down to -5C. If there's a chance those plants have been indoors for more than a day or so before you got them, then I would try and protect them somehow because it is possible they have be come de-acclimated to cold. Are they actively growing?

Do you have a shed or garage they could go into for the duration of the cold spell? If you could keep them a little above freezing it would be better than being in a warm house for a week or so.

This is the best advice, in my opinion. I might also add that if they get light, all the better, but it would not be necessary when it is cold.

brought them both boxes inside, in the hall way, so it's got to be better for them new plants than what the weather is saying today / A wind chill will mean that during the day it will feel like -10C to -15C, not to mention the snow that were going to get Glare

Good that you brought them in Thumbs up Don't worry about windchill, it doesn't affect plants as far as temperature is concerned, they will only experience the actual air temperature because they're not warm-blooded like us. Sounds like you're getting a taste of Canadian winter weather, although I think I read that what you're getting there is from Siberia. It's actually going to be warmer here in my part of Canada today than it will be in the UK!

Tell you what they were bloody heavy bringing them in, I think the overall weight of them was 1000000 pounds...lol Think I was attempting the worlds strongest man when trying to lift them....

oh, I never thought of that about plants and the wind factor, ha! quite an interesting fact, yeah we are supposed to be getting "the beast from the east" and it's coming in from Russia, We don't normally get this type of weather as we are approaching March, it's normally a sign of spring on the way but apparently not for the next few days, week or so....here's the little blighters sat in there new home for now :)

(just realised that on this site there's a place for just about everything and didn't know about the perennials bit)

I can see lifting those wasn't for the faint of heart! But at the stage of growth of the plants you did the right thing (but be careful of your back when you put them back out, maybe borrow a trolley or something?). Plants that have had a chance to get used to the cold can take lower temperatures than "de-hardened" ones. Here in Canada I'm further south than you but way colder in winter (and warmer in summer) because you have the advanrage of the Gulf Stream. I used to live in the UK which was equivalent to US hardiness zone 9, moved south to Canada, hardiness zone 4 Hilarious!

Thanks, looking forward to seeing them all grow and bloom over the summer, I'll post pics of them as they start there adventure! and yeah, think I'll get a mate to help me put them back out into the garden..... I was trying to see what "zone" I am in here in the North East of the UK,. and think I'm in zone USDA 7 or 8 according to a web page on the net.

So once these have been out all summer this year and it starts to approach winter will these be then OK to leave out all the time, or will I have to bring them back in end 2018.

Been reading about plants in tubs and they need a little bit more looking after as in nutrients and watering etc. Garden center told me that next year it'll probably be a good idea to add some fertilizer for there food, but should I feed over the summer with some plant food added to the water?

Bet moving to Canada from the UK was a great experience! where in the UK did you live?

This map even gives Newcastle-upon-Tyne as zone 9. That would be in a narrow band along the coast.

http://www.plantmaps.com/inter...

If they're normally hardy there they should be OK outdoors but, being in a container, they will be exposed to more extremes of temperature. The bigger the container the more buffered the plants are from the cold. I would think they'd be fine down to about -5C next winter once they're used to being outdoors unless any are particularly tender.

If there's fertilizer in the potting mix you probably don't need to give them anything much this year. See how they grow. Yes, next year they will probably benefit from some fertilizer but they won't need much.

Before coming to Canada I was living on the southern-coast of the UK.

Thank you, yeah the mix that I got all ready has some fertilizer mixed in with it, so thanks for the advice, Will post back with pictures during the summer!

I used to live down on the "Isle of White" much warmer than here in Newcastle!

awwww, looks like we are getting hit with a "mini beast from the east" and they have been out in the garden now for about a week, it was after the snow had gone and I thought we were out of the woods with the weather as the temperatures started to climb above 6 degrees, the sun even started coming out, we had quite a lot of heavy rain the past few days and now were getting hit by the snow again, outside temps are about -1 to -2.

Just come in from work and some are looking a little dazed......think they'll be OK?

Can't really get out there now and heave them back inside...
