Acacia frost damage
Hello All,
My Acacia Dealbata ( about 4 years old, 3 of which were in a pot ), 9 foot tall, has suffered in the late frost. It's leaves are all drooping and going a brown colour. Anyone else have the same problem? Is the tree likely to be dead or might it regrow new leaves? I have seen websites saying they can withstand several degrees of frost, but younger trees are less hardy, and anyway, we had a lot of degrees of frost. Andy ( Plymouth ) |

Andy ( Plymouth ) Andy, ours in the garden have succumbed. But in the manner of Acacias, never say 'never'. There's always a chance they'll sprout from the root. Just make 100% sure yours are well drained and that, from now on, they're protected from frost Ray takes old compost bags and pops them over worrisome plants. A bin liner or two might do that for you, perhaps? -- Sacha http://www.hillhousenursery.com South Devon (new website online) |

It must of been really cold here over early January eh? I only got back to the UK a week ago and I'm still discovering more carnage, pleasantly surprised overall though, especially by plants I would have though would have succumbed. As I remember from a few years back I did have a lingering 5' plant (3-5cm girth) in a 15 Ltr pot go completely brown from frost damage but it did recovery from the trunk and the base of some branches, the pot used to regularly freeze on that one as it was parked next to a rural field and sometimes didn't thaw out for weeks at a time. So I wouldn't worry about the roots freezing, but give it water if it does start to shoot. That same Acacia suffered irregular watering and neglect by me in the summer. It used to regularly drop every one of all its leaflets off all the leaves when the compost went to dust, but always recovered after a good soaking a bucket! As frost damage to around -7 or 8C is physiologically similar in many ways to a drought scenario I'd be inclined to think it will recover. They'd all be better off in the ground in the sun so they can make some real progress!! |
Oh and don't let the roots freeze if you are watering them! Only leave them unprotected if they are well neglected and well drained, try and forget about them until early Spring!!!
I know dealbatas can tolerate occasional overnight -7 - -8 degrees in Adelaide and Mount Gambia, South Australia but then this isn't prolonged and its usually above zero during the day and they also have a long, hot summer to build up their sugar-alcohol levels so they are probably better equiped to supercool and avoid freeze damage freeze going into the winter. From what I gather we got a prolonged frost of -11 degrees+ to -1 degrees around here (Salisbury, Wiltshire) that lasted for over a week in early January. This snow isn't even touching them now but! They are even looking slightly heathier than they did a few weeks ago. I was doing some planting in Virginia, USA over the winter as a favour and it was the only oppotunity I had to plant all year. Pot grown Pittosporum tobira dwarfs, Raphiolepsis indica and huge Lagerstromia 'Muskogee' transplants, Liriope muscari and Mondo grass (Liriope japonicus) liners. It was 5 degrees when I planted and everything was frozen from the night before when it got down to -11 degrees which is unusally low for over there, even though I had made an effort to protect them. I had to dethaw the plants by soaking them in a bin of water before planting and mulching! 1 month later and no sign of any damage so I'm told. But remember they were grown in a climate with a very hot and humid summer however! Wish we had hot enough summers to get Crepe Myrtles to flower over here, all we get is rain, sleet, fog and low cloudcover all year!! Let us know how your Acacias get on, with this thread. |

It's extraordinary, Charlie. You've had it worse than we have here, so near Dartmoor and yet you're supposed, if anything to have a milder time of winter in Cornwall. This has been a very peculiar winter where snow and ice are concerned and it doesn't sound as if it's over yet.

We've had a lot of snow for us but that means very little indeed by comparison with the rest of the country. Matthew did start up the heating in the tunnels just in case we had a really huge dump of snow because it's dangerous for the polythene but it didn't get near that point. Last night went down to -1 while -4 was predicted. I don't know if it went that low in other parts of Devon, though. -- Sacha http://www.hillhousenursery.com South Devon Perennials & shrubs online |

More like Bedford - we have the nearest to a continental climate that Britain possesses, though it's still very maritime, of course. Norwich is more maritime than we are. This year, the lows have actually been fairly high (no more than -5 or -6), but we haven't had a sustained period of near-freezing days for a decade. We used to get much colder conditions, which may still return (e.g. -5 in the day, -10 at night, for several days). Regards, Nick Maclaren. |

Usually, though, it would be the other way round - plants which don't look dead now just fall over when you expect them to start growing. Maybe you'll be lucky and one or two might resprout come the warmer(?) weather. -- Jeff |
Well I'II have to check the Albizia julibrissin, its 3+ years old in the same garden as that large Acacia that has gone brown.
Interestingly all the Grevilleas, 'Canberra Gem' etc, whilst I know they are pretty hardy have come through unscathed whilst some of the Callistemons (C. Citrinus etc.) have been cut back to the ground, whilst others like C. phoeniceus in a much more frosted situation have come through ok??? Don't know what the problem with Phormiums is, all the tenax and cookerium varieties here have come through no probs as with the 3' Cordyline Dark Star (Red) with 3" wide leaves unprotected, though the scrawny one in a pot next to it has dropped all its leaves, but the tips ok. Even got a crawny phormium in a pot came through. Stupidly left my Phoenix palm out all winter along with potted Cannas...money down the tubes as they are all mush. Palms will regrow I reckon as spike is OK so far but leaves have gone.... Mulch is getting thin in a few gardens, hope I don't have loads of clients calling me up to ask where there Cannas have gone?? Hopefully they'll be OK as there is so much to them and they are so vigorious that a few rhizomes underneath survive when they are in the ground. |
