Replacing diseased tree
 

Last year our 15yr old Laburnum started leaning over pecariously but it
seemed to be otherwise okay (if a bit wobbly). This year however after
flowering the leaves all turned yellow & withered and when I cut a branh
off, the heart wood was black. I suspect some sort of fungal infestation
(perhaps entered through damaged roots?)

Anyway, I've chopped it down and dug up as many of the roots as I can. Is
it safe to replant a new tree in the same spot? (It won't be another
Laburnum).

The heartwood of laburnam is very dark in a healthy tree.

Never knew that. Thanks. Still think the tree as doomed though. ;-)

Because of the dark heartwood any local wood turners will be keen to take it
off your hands, judging by my experience from when I cut one down.

As Mark has said, the dark heartwood is normal and turners love it. As
to cause of death - even with a full lab post-mortem it's often
difficult or impossible to come to a firm conclusion, there are so
many potential pathogens in a normal good soil that it's difficult to
finger anything with certainty as the cause of death.
So don't worry, just plant something you like and there's a reasonable
chance that it will be OK.

Already offered it on Freecycle (and expecting someone in the next hour or
so).

Cheers Rod. That's what I wanted to know.

What I didn't say is the usual stuff about investigating the physical
and environmental conditions. Insecure on it's roots? Waterlogging,
drought, badly compacted, shallow or panned soil etc. Also a lot of
people grossly underestimate the extent of the tree's roots and do a
lot of digging etc in the root zone - the feeding roots extend well
beyond the canopy and any disturbance in that area should be kept to a
minimum. For the same reason when preparing for planting prepare an
area many times wider than the root spread of your new tree and keep
it clear for at least a few years.
