They usually mean that the ground is not frozen - a light frost overnight should disappear quite quickly the next day, either in sunlight or because daytime temperature is more than about 8 degrees C. A better guide is probably temperature - if its been below zero degrees C for longer than a week day and night, the ground might start to freeze, though that's much more likely in January than it is in November. At this time of year, the soil is just starting to cool down - September/October is when soil is at its warmest in the UK.

This assumes your roses are already outside, and haven't been kept indoors for a length of time - if they have been inside, they'd need hardening off prior to planting. November through to February is the time to plant bare root roses, but not if the ground is waterlogged or frozen.

Ordered from yougarden 6th of October. Delivery next week had problems with weather and suppliers, you just can’t win. Thank you

as bamboo says as long as the ground isn't frozen or waterlogged get them in as soon as possible.

Below 50°F/10°C is tempting fate. Most reputable nurseries here would refuse to ship out of season. I would postpone shipment until the Spring. The rose bushes need several weeks to settle in and would we not get a hard freeze in December? Doubtful!

5-10c is a warmish winter day here ;o) so if it stays at these temps the plants and pests will be very happy. The reputable rose growers [Dave Austen & Beales ship October /Novemebr and offer good advice if conditions are grim.]

I don't think shipping roses at those temps is good advice. You also have to account for night temps. It's too cold and getting colder.

Bare root roses are always delivered in November here. In our UK climate it is the recommended planting time. Lasting hard frosts at that time of year are rare - early morning frosts usually melt during the day and the ground doesn't freeze hard except in very occasional winters - I only remember two in my lifetime.

It's not the best time to plant - sorry. I know you want them now now now, but if you have to ask, I think it's prudent to wait. We are in a hard freeze right now as I type this and my furnace is blasting away. Isn't this your weather for next week?

Thanks everyone

"Next week" has arrived and the ground is still open and suitable for planting. I am ordering trees this week at the recommended planting time in the UK. Sorry. Hundreds of people will be doing the same. If ordering is left until the spring the selection will be much smaller as many lines will be sold out.

I also ordered several choice plants, but I'm erring on the side of caution and holding off shipment until Spring - my 'crystal ball' went dark and you can't predict the weather and the plants need time to settle in. It has no affect on quality or quantity. My order is guaranteed and the garden center will nurture and care for my plants until it's time to ship.
