Thanks to all the posters so far - I'm rather amazed at the response!

Actually, I do have tree root structures in this ground, principally
three large oaks, and I would not wish to do anything do harm them.
Also three holly. Why - is there something important I'm missing
the trees?

Hi,
Have just (mechanically) cleared 0.25 acres of old and impenetrable
rododendron, and having removed the roots, will rotovate and overlay
with 6" of soil/sand/loam mix before laying a new lawn.

However, I'm expecting some potential problems:

First, I'm aware that the rhododendron is toxic to other plants, and
I'm trying to understand what may not be plantable in the reclaimed
land (ie. lawn, laurel, fruit trees etc). And also what might be
done
to neutralise this effect.

Second, I'm aware that there is likely to be rhododendron seeds left
in
the ground, which will doubtless sprout. Will glyphosate neutral
these,
or do I require something different, and will that be fine to seed
lawn
in mid September.

Any help appreciated.
Kind regards,
David.

It is probably not a good idea to be placing 6" of soil on top of any
tree roots much less rototilling them.
