When and how to trim coral trees?
They should be pruned after flowering and needs to be done yearly to keep the tree strong and to keep limbs from breaking.
Remove branches that are less than upright, as these are most likely to break. Remove any branches that are crossed, rubbing or less than 6 inches apart from the same trunk.
I have a coral tree with beautiful bright orange flowers. However, for the first time in 30 years, it is dropping some kind of weird powdery substance on the ground and table under it. The tree appears to look fine and the substance seems to be coming from the split open seed pods that grow out this time of year after the blossoms are gone and before it drops all of its leaves. I am very sad, as I have lived with this tree 30 years now and it has never had any kind of weakness or pest problem. Any idea what this could be?
I have not been able to find any disease or insect issue for a Coral Tree that would match your description.
I do think you may actually be seeing excess pollen dropping from the plant, which would be perfectly normal.
I have a three foot coral tree in a pot. I would like to put it in the ground, but can I keep it 20 feet tall if I prune it frequently? I planted it from seed I got on vacation.
If you have success with this tree planting, it can be fast growing.
Correct planting, keeping watering low and not fertilizing can help.

I am based in Gauteng and have successfully grown seeds by placing them in cotton wool until they sprouted. I planted 3 sprouts per planter and they have grown by approximately 12 to 15 centimetres each. What do I have to do for the stems to grow thicker? How long should I wait before planting them outside in the garden? Thank you
To make sure the stems grow thicker and stronger, you should give the plants more light. This can be done by placing the plants in a sunnier window, or providing artificial lighting, or placing them outside if it is warm enough.
You can plant them in the garden as soon as it is warm enough, but preferably in spring or fall. Here is more advice about growing coral trees:
How do I keep my Coral plant from growing so quickly in the pot it is in? The are lots of shoots coming out on the lower part of the stalk. It is a large pot about 15 inches across and 20 inches deep. Would deadheading the top be beneficial.
Regular pruning is needed to keep a container planting from overtaking the container.
Ants are not known issues with Coral Trees.
Moths are a known pest.

I live in Spin on the Costaq Blanca. This year, for the first time since 1926, we haed snow. Not enough to blanket the ground here but it was quite cold. Since then, my Coral Tree (in a pot) has lost all its leaves. Will they grow again? I am devastated because it was such a lovely addition to our small garden. Any advice qould be gratefully received.
Mother Nature can frustrate us!
There are over 100 species of the beautiful Coral Tree and the cold tolerance can vary. Many can survive temperatures down into the low to mid 20 degrees F.
Some types can be damaged or die off from slight dips below 30 degrees F.
Even though your tree has lost it's leaves, don't give up yet. Check the branches, do they snap off or bend? If the branches bend, they are still alive.
Scratch the bark, is it green underneath? A live tree should appear green under the outer bark.
Give the tree more time this spring to see if it can leaf out or even grow up from the roots.
When I lose something in my own garden, I try to remember; a loss in the garden makes for new opportunities.
I know it still hurts to lose a treasured specimen, especially a lovely Coral Tree.
