I have a 4 year old jacaranda which has never flowered but has about 6
different trunks. Should I prune some of these and how do I know which
one?

I also planted an Evergreen Alder at the same time (about 2 meters
apart) which this year for the first time appears to be losing its
foliage. It has done this in winter before, but always before the
foliage has been so thick at this time of year you couldn't see the
branches. Could it be dying, and if so, why?

Also, should Robyn Gordon Gevillea be pruned? Mine, planted 4 years
ago, is only about a 2 meters tall is sprawling out and taking over
lawn?

Can anyone help?

g'day robbie,

from my expereince i would say the jacaranda has suffered some damage
and in these cases they often never turn into a good solid tree, you
could try by selecting the upright that represents the strongest
growth but where this growth i will assume is coming from a damaged
area that could be a week link for alter on in life. also there may be
better native trees to do the same job.

as for the alder i don't know much about them but are they an exotic?
sounds like it may be suffering due to dry conditions maybe? again
replace with a native more suitable tree.

the hybrid grevillea can handle pruning to shape so go to it removing
growth may give more flowers then attract more birds.

With peace and brightest of blessings,

It should definitely be pruned regularly. You can prune it quite hard and it
will reward you very quickly. However -- I would not prune it in high summer.
Prune it after its next flush of flowers just to tidy it up, and give it a
heavier structural prune in cooler weather.
