Hello to all :

I would appreciate some advice on the correct time of the year to repot
Scots Pines.

I live in Buffalo, New York. It is the end of April and temperatures are in
the 50's and 60's +. Is this a good time to repot Scot Pines ? There is no
candle activity yet.

Thanks for your help....

Hi Gregg,

from http://www.bonsai4me.com/SpeciesGuide/Pinus.html

Repot in mid Spring every two to five years, depending on root-development.

Repot as the Pine comes into active growth (the candles have extended and
the new needles can be seen held tight against the candle), do not repot
too early. Mugo pines react far better to Summer repotting.

Use a very free-draining soil-mix. When repotting, pine soils will often be
seen to contain a white, thread-like fungus called Micorrhiza, which are
very beneficial to the health of the tree.

When repotting, retain a small quantity of the old compost to ensure that
Micorrhiza is retained in the new soil mix. For the same reason, do not
wash the roots. Remove old, compacted soil by hand.

It is not necessary to prune any of the foliage of the pine after
rootpruning to 'balance' the tree. The waxy needles of a Pine require
relatively little moisture uptake from the roots and there is no need to
try and reduce transpiration through the above-ground growth. The more
foliage the tree has after root pruning, the more strength it will have to
repair and regenerate the rootball. The tree will 'balance' the roots and
foliage itself.
