We have this beautiful broad leaved tree in our garden that's doubled in size in the last 6 years and has looked to be quite healthy. We've never been able to determine precisely what it is. I've only seen one other tree like it in Milton Keynes.
But this week we noticed some of it's leaves were beginning to look weary then quickly they've lost their colour and begun to shrivel up. I can see the signs of deterioration showing on other leaves too while most leaves are still healthy.
I fear it may have contracted a disease. We are desperate to identify the cause and take any actions we can to protect and keep this tree in good health.
I've attached pictures to show the tree with close ups of the symptoms.
Its a Indian Bean Tree Sorry I do not know what it is suffering from
Thanks for identifying the tree. You're spot on - now I can find more information on the tree.
The symptoms of the leaves beginning to wilt on some branches then withering, turning brown and now falling to the ground, have taken hold just this week. It's frightening to see this take hold so quickly. The other leaves are begining to fade from green to yellow and I fear all the leaves will go the same way.
There are white patches on the trunk / bark. Not sure if this is a fungus or such. I'll take a close up picture and share.
I'm sorry to say but I think your Catalpa might have a Verticillium infection. There is some information about the disease and some advice about controlling it here.
It is a lovely tree I hope you can save it...
Thanks. I think you're right - the description of the symptoms match what we're seeing happening to our tree.
Really appreciate your responses - now I know what actions to take to help our tree survive this infection (if it's not too late):
Our tree is about 12 years old, so I hope it will survive. Certainly flourished during the 6 years since we moved into the house and inherited the landscaped garden.
Inshallah, I'll have good news to report in a few weeks time.
Hi Sorry to see you are suffering from something serious, must be your bad weather but the tree is very easily propagated from seed Ok I live in warmer climates but from seed I can grow a 18 foot tree in 4 years Here we cut them back at least half or more each year so a little pruning will not upset it It will probably have more gusto next year as a consequence
the info in the link suggests that fungicides, even when used systemically and applied as a soil drench, are not an effective means of control when dealing with established trees. Apart from anything else you risk killing off beneficial fungi in the soil which have formed mycorrhizal associations with your tree and may be helping your tree survive...
I'd concentrate on the the TLC to combat the infection.
Be sure to sterlise any tools before and after each use when pruning!
I hope all goes well.
Thanks for clarifying that Jen. I was struggling to find the right systemic fungicide as it seems the verticillium infection does not have a specific treatment available. I was also concerned about the pondlife (goldfish, newts frogs, snails, (even had a visiting grass snake) etc) that may be indirectly affected from a fungicide soil-soak.
I take some comfort from others' experiences where parts of a tree were affected but some / most of the tree survived through TLC. Also from your feedback Steve that pruning can stimulate better growth.
Apart from pruning the affected branches now (taking sterilisation precautions), is the end of the growing season the best time to prune other branches back? That would be late October / November in UK. How far should I prune the branches? Back to the last "Y" fork in a branch?
Now I look at it, I've clearly not been doing it any favours by letting it just keep growing. One of the branches looks like it's not strong enough to support the burst of the growth of leaves this year - I fear it may snap - especially as visiting birds like to perch on it before landing on the lawn or visiting the bird feeders to eat.
Could the birds have inadverently led to the tree being infected?
My concern extends now to my other trees, in particular the Japanese Maples. Although they are not close to the Indian Bean Tree, they're in the same garden. Other trees / bushes in the garden include false acacia, silver birch, laurel, jasmin, holly and sycamore.
Thanks again for your support. Glad I posted on this forum
I have seen other people and the local Marie cut them back almost to the trunk I try and keep the tree in an umbrella shape when the offending branch is vertical cutting it back to fork in the right direction Others I reduce by 2/3
If its a fresh shoot going in the right direction often just snipping off the tip
PS twas 46 degrees today
