I have a laburnum tree in my front garden. It is about 20 years old.
This year it flowered as usual
Today I noticed that all the leaves have gone brown and died.
There are flowers/shrubs underneath which are not effected
It seems green when I broke off a twig.
Does anyone know what has happened?
Hi Carol Anne
A Laburnum can contract a disease called `Tip Dieback` i was made aware of this disease in the early nineties it is a fungal disease
I have tried the RHS website and cant find anything on it
Laburnum trees only live till about 25 years
I dont know if that is whats wrong, hopefully this will give you something to try and search
Thank you guys for the replies.
There is not any pollution that I am aware of.
I will look up tip dieback.
I did some more research and the reason I could not find anything on
`tip dieback` because it was it was under another name.
It could be a disease called Sudden Oak Death or Phytophthora Ramorum, i should have remembered that I was only talking about Phytophthora two days ago ( old age creeping in)
It transfered from America to the Uk in 1995, It causes die back on the tree
Other causes could be old age, or you could try rocking the tree if it moves the ground is waterlogged and you have root rot
Silver leaf you will find info on the RHS website
Is it wise not to plant another tree in the same spot if this one has to come down?
The twig is still green inside, does that mean it is still alive?
Laburnum are susceptible to Silverleaf disease http://www.rhs.org.uk/advice/profile?pid=245
Green doesn't mean it's still alive Carol, not when it looks as dead as that. It just means it hasn't been dead long.
I don't know laburnum diseases but I'm sure it will be a disease. It's not old, mine were planted around 1960, I've known them for the past 20plus years. They do have bits of die-back but I've been lucky and never lost a whole tree.
If it is Phytophthora it is not advisable to plant another tree and you would need to check what trees would contract this disease before planting ,there is quite a few
Its still alive if there is green, if it is phytophthora it will gradually move down the branches
It may just be old age, if that is the case then you can plant another Laburnum
Rock the trunk of the tree if you can and see if it moves its root rot
Before deciding on what it is, just go through the four different symptoms i have told you about and work on the process of elimination and see what you end up with
Use the link that Dove has given you on Silver Leaf it will save you searching for it
Thanks guys, you have been a real help
Hi Nut, I understand what you mean about the green, no offence
Hi BB. I'm not easily offended. I give my opinions and respect those of others. That's how a forum goes for me
Thank you. It does look like the picture a bit. The bark is orangey and has stripped off in some places leaving it silver.
Interested in Buddyboy's comments on root-rot. My 20 year old Laburnum started dying last year. When I shook it it did wobble and it came out remarkably easily as there were only two large roots about 25mm diameter visible. If this was indeed root-rot, does whatever cause the problem stay in the soil (if indeed it is in the soil and not airborne) and is it wise to replace it? Finally, is there any way to cleanse the soil?
