Judas Tree

We have a small Judas tree, Cercis siliquastrum, in our front garden.  Last year it was covered in bright purple/pink blossom but this year it has produced only one cluster of flowers.   It made quite a lot of growth during last year.  Has the new growth used up all the energy of the plant?  I read that they strongly dislike feeding, that they will tolerate pruning at the end of spring.

Does anyone have any suggestions as to how we can encourage the tree to flower next year?  It gets a great deal of light, though is not in direct sunshine for a lot of the day.  It is healthy otherwise.

Many thanks

    I envy you being able to grow this beautiful tree. They don't grow at all well where I live because our summers are too cool and rather unpredictable. They need a warm summer to produce good flowers in the following spring. Did you have a hot summer last year?

    Apophthegm -  a big word for a small thought.
    If you live in Derbyshire, as I do.
  • Yes, it was a good summer.  Thanks - it may just be that it doesn't have long enough in direct sunshine.  The sun goes off it at around 10.30am - though it gets masses of light.

    They grow naturally at woodland edges, where they get full it may be not enough direct sunlight.

  • Yes - I fear it may be.  It has been in its present position for three years - the first two years it flowered well, but this year not.

    Very interested in this conversation.  Can anyone give me advice for my Judas Tree which I planted in September last year.  It is producing very healthy heart shaped leaves but absolutely no sign of any flowers.  Is it normal to have to wait another year or two for these?  It is in full sun against a south facing fence.
