Hi yiz
If we get temperatures < -10 this winter like 09/10 etc, does anyone know of a way to keep hedges alive that usually get killed by these temperatures?

Covering them for the 10 days (assuming the cold snap is 10 days) with black polythene any good?
Having a fire/outdoors stove lit beside them at night?
Have a hot water pipe circulate near the roots?

Has anyone any simple effective tips?

Thanks!
PD

What kind of hedge? How established is it? If the roots freeze as a result of extreme low temperatures, and the soil ends up completely solid, no polythene is going to help much.

Hi Tippben,
I was thinking in general for everyone _ but for my specific case- griselinia- they withered after Jan 2010...

Cheers

I always think it is better to work with nature than against. You either take a gamble and assume our Big Freeze of 2010-2011 was a once in your lifetime event and proceed accordingly, or you simply plant a hedge that will survive low temperatures.

That is the ultimate advice, Sive. Following that logic I should now go out and dig up the 6ft high grisilenia and put laurels in! Aaaagggh. Damned logic! Smile

Sorry Phelim....I just wasn't sure whether you were referring to a new or existing hedge...and indeed what length/size of hedge either. However, if you have a 6ft high Griselinia then it must have survived the Big Freeze ? Am I right ? If so, it will survive again. We live on a hill here, and 2 near neighbours' griselinias survived perfectly well.
And there are plenty of other choices, apart from laurel ! Beech, or yew for instance.

Mulching with a deep layer (1")of autumn leaves will also help protect it. You could fleece it to help protect the foliage. What's the point of a mostly dead hedge, with rootstocks surviving though? Not much good from a privacy point of view! Our neighbours' Griselinia survived the first hard winter, but it didn't gather enough energy over the summer to make it through the second.

If you have the money, grub it up, cut your losses, and plant female Holly. Slow growing, berries for xmas (variegated varieties available- any variety called "King" is female, and will have berries. "Queens" are male. A bit queer eh? That's the way cultivars are described though!), and good firewood. You can nearly coppice and pollard it (in winter) at will. Expect to pay at least a fiver for a good bare root plant, very little growth in the first year, but a foot a year after that.

Hi Sive & Tippben,
the grisilenia are from spring 2011 and have reached 6 ft already. But they are spindly.

We will weather any weather that comes. What is the worst that can happen anyhow. I'm grateful I've little ash trees planted and that the mountain ash (immune to the die-back fungus) are thriving Smile

I'll get osme mulch for their roots and a duvet or two.

thanks and best wishes.
P

Thought I could help you but....Did you know,
Do you want to have a divine hedge in your life? Then your goal should be to become a servant of God.

When you hear the word "hedge," what you think of? Most people think of a hedge made of plants. You may have a set of hedge clippers somewhere in your garage that you use to trim plants. But the word "hedge" in the Bible describes something more substantial than a bush. The Hebrew word really means "wall." A hedge was a defensive wall often built around a city. The bottom part might be comprised of stones or hard packed dirt, and there might be thorny plants on the top of it.

The general idea of a hedge is that of a protective fence-a barrier. In his conversation with God, Satan pointed out that God had built a spiritual hedge around Job, around his family (household) and around all his possessions. Job couldn't see the hedge, but Satan could. As I mentioned in the last message, there are many things that exist in the spiritual world that are invisible to our eyes, but that doesn't mean they aren't real-they are. It is a wonderful insight to realize God can provide a spiritual barrier around His servants to protect them from spiritual attacks. Let's notice a couple of things about this divine hedge of protection: Want to read more>>>>>>>>>>>> http://www.sermoncentral.com/sermons/surrounded-by-gods-hedge-of-protection-david-dykes-sermon-on-ot-characters-149041.asp?page=2
There's more to this hedge business than meets the eye.
