Q. Laburnum Tree

I have a Laburnum tree and have lived here for 20 years. The tree has always flowered, but this year there are virtually no flowers. It has leafed as normal. Can you help please?

If you had an unexpected frost or freeze during late winter/early spring, this could have affected the buds. The soil could also be lacking phosphorus. Add some phosphorus-rich fertilizer or bone meal to the soil to help encourage blooming.

Q. what type of tree/bush is growing in my garden?

Can you confirm what type of tree/bush this is growing in my garden? I have attached two pictures of a bush that is in the front garden of my new house. A lot of people have said it’s a laburnum but I have not seen any yellow flowers. Many thanks for your help.

I agree this is Laburnum.

It seems to be considered a difficult tree to grow, but I also read reports of once established in a good location it is a spectacular blooming tree.

Here is a link with it's growing requirements and characteristics.
Please note the fact that all parts of this tree is poisonous.

Q. Laburnum tree

I have a laburnum that has grown from seed to about six foot high and half inch thick at the soil level. It has no branches. although side shoots every spring. If I remove support, it whips about. Should I cut the top off to get it to thicken and branch?

I would consider placing your Laburnum onto a trellis.
You can grow it much like you would a Wisteria Vine.

It is best to grow it with one leader and they generally do not need pruning.

Q. care of laburnum tree

Are there any tricks to dealing with the unsightly seed pods left dropping from my laburnum tree once the flowers have faded? It can be pretty time consuming to go branch by branch and pod by pod.

Unfortunately the seed pods are part of the natural tree process.
Removing the seed pods that drop by raking and disposing of is recommended.
All part of the tree are poisonous, so keeping the tree litter cleaned up is crucial for the safety of children and pets that may mistake the seeds pods for something to eat.

Q. burning Laburnum seed pods

My neighbor is collecting all the seed pods from his laburnum tree and plans to have a big bonfire with them next week. Will this be a health hazard?

I don't see any data on whether people have been injured by burning laburnum wood, but breathing the smoke could potentially be a health hazard. The toxin in laburnum is cytisine, a chemical relative of nicotine, so it could probably be inhaled in the smoke when the parts of the plant are burned, like nicotine can.

Q. laburnam tree

Hello! I’ve got a 20 year-old laburnam tree in the garden and up until last year it was a prolific flowerer. But last year, about a third of the tree, all on one side, didn’t bloom at all and actually looked like it was dead. The rest of the tree bloomed as it usually did. But this year, the third that last year looked dead is fully bloomed and the rest of the tree has only got a few bblooms – 3 to be exact! Have you any idea what might be causing this behaviour and is it actually a problem? Many thanks for your help.

Maturity is at 15 years, and blooming regularly by the age of 3 to 5 years. Some growers do report a every other year bloom.
