This is a difficult one but I would wait until the weekend is over when the snow and ice should have finished and then give a light watering in the middle of the week; just enough to make the loose soil moist.

Thanks Jimmy. Before I saw your answer, my husband had gone out with WARM water, saying that as the planting holes were only dug yesterday, the soil wouldn't be too compacted. So he tried giving the Laurels a good drink but thought the water only penetrated to about 2 inches.

We'll now wait for the thaw.

I agree with Jimmy. Frozen ground means there's at least some water in the ground already. It can wait a few days.

Many thanks Paul.

Luckily laurels tend to be pretty tough!

That’s a relief Penny, thanks!
