Griselinia leaf tips are black

bishee · Posted: Sat Apr 26, 2008 9:17 pm Post subject: Griselinia leaf tips are black

Hello

I planted some 1-2 m high Grislinia hedging last October and, of the 20 plants, 10 are in the shade and 10 in brighter light. Then ten that are in the shade are ok. The other ten have black rolled-up tips to their leaves. It is as though the tips have been burned by heat and the leaf tip has become black and brittle. I cannot think that the sun has been strong enough this time of year .. so I can only conclude that I have a problem.

Can you help?

Hi Bishee

Are the griselinia that are in the sun also in a more windy ,open spot? You might find that they have had wind or frost damage.

I knew somone locally to us who planted 200 variegated griselinia plants around their garden. The sheep nibbled the shrubs (costing 10 euro each with labour) . All of the plants died except about four that were out of reach to the sheep. We were thinking that there must have been something in the animals saliva which killed the plants.

Is there any new growth coming on them now we have warmer weather?

Cheers

Ian

Was at a freind house this eve and noticed his grisselena hedge which is years old had what appeared to be tiny new growth leaves which were all black, don't if it is wind or frost damage or whether this is normal Question

Set about 70 rooted ones myself last october in a pretty exposed site, about 65 have survived and still have leaves, going to pinch out the growing tips tomorrow as they are pretty scraggly looking, had a few left over and planted these in buckets so have a few spares to fill in the gaps. Don't know if i'm doing the right thing or not Question

Thanks ..

looks as though this still needs answering. I planted Griselinia because they are particularly tolerant to lots of wind .. and, in any case, I have now had frost for weeks. The damage was only noticed recently ... that;s not to sya, of course, that it wasn't damaged earlier ...

Thanks for this .... except I have had no frost for several weeks ... and I prefer the softer, lighter leaves of the Griselinia. So - you're sure that this is no leaf bug or spore problem?

Hi

The black tips are cripy - like potato crisps. They disintegrate easily, with little pressure.

I have no idea how to post images - though I can see an Img icon on the messagy body bar above what I am typing. When I press the Img button, it inserts an Img leader into the message body but I don't know how to link my image to it.[/img]

If you press the img button once, then post the image address, then press image again, that should add your image.

Thank you ...

Thats the thing with Griselinia it is tender to frost or icy winds, but if you live near the sea (southampton) the damage will usually be minimal, just restricted to the new leaves. A hard frost can kill stems, now that is trouble but rare. bishee, I suggest you feed your hedge with sulphate of potash in autumn to toughen the stems against frost damage.
