Paulownia tomentosa yellow leaves

Is this normal for leaves to yellow or is it caused by poor drainage (its been very wet here all month in Ireland) or possibly too shady (only gets morning light)?

    Can we see the whole plant please?
    Also - is it planted directly into grass, and is that another tree right behind it?

    Yes, planted directly into grass, there is a Fatsia japonica and a crab apple type tree behind it. It's a shady (ish) wild patch at the back of the garden. We may need to move it?

    The yellowing foliage isn't necessarily a problem as such, but the site is. Even if it thrives, it far too close to your other tree, and planting anything into a grassy site without clearing a proper area isn't a good method.

    This is just an average bit of info about them

    They want to be very large trees....

    they grow very quickly … even if you coppice them to the ground  each year they can grow several metres tall in one season.

    Paulonia need full sun and well-drained soil to do well.  Yours is stuck in a shady damp corner with insufficient sun and competition for nutrients from the grass at its feet and the other plants nearby.  I have a 2m sapling I planted 3 or 4 years ago andit has tripled in height despite the last 2 summers being very hot and dry.

    You need to find it a sunny spot and create a good planting hole with some grit in it and then plant it on a slight mound to lift it a bit.   Make the mound at least 1 metre diametre and cover the soil with a mulch of chipped bark or similar to keep weeds down.   Water well before diggingit up and then again after replanting and get as big a root ball as you can.  Best to do this in autumn when the tree has gone dormant so it has all winter to re-establish a good root system.
