Hello again,
The bougainvillaea has been thriving; growing about 8 feet high over the
door from house to conservatory. About two or three weeks ago the tips
of the newly emerging leaves blackened (in some cases extending to the
whole leaf) and there is now no further leaf growth. All leaves are
affected.

I didn't post anything last time because I'm really just guessing but the
damage does sound like frost damage. Is the affected plant in slightly
different circumstances to the other three where it might have got a couple
of degrees colder? Maybe someone opened the window for ventilation or maybe
there is a natural draught which might have got it. Alternatively, maybe
overwatering and a slightly warmer position have started it into growth at a

I'm tempted to agree with that. Temperature can vary a lot in a
structure like that. You will have many different micro-climates in
there which can cause you trouble or which you can exploit to the
advantage of your plants. Do some measuring and recording, watch your
plants and make your conservatory even more useful.

Thanks for those points Martin and Rod - in looking into it further I
think it may well be a combination of factors - it definitely did get
'well' watered a little while ago and, subsequently, there was some
particularly cold weather - it looks like this particular plant may be
getting a rather cold down draught from an air gap above it. We're going
to wait and see now for a while.

Regards, Colin
