I have a very sickly ceanothus that has brown leaves (those that are
left) and is very straggly. It was pruned lightly last year and came
good but having read some of the other posts on this subject I think it
may be just too cold for it here (Aberdeenshire)
The really good ceanothus species are Californian and generally are
native to fairly mild Mediterranean climates: in the sense of lots of
winter rainfall and a long, sunny, dry summer.
Admittedly I'm basing this remark on a possibly faulty stereotype of
Scottish weather, but I can hardly imagine a climate less congenial to
ceanothus, what with clouds, chill, and rain.
Warmth and sun and drought: that's what they want, though they
probably do better with some moisture down deep.
Your stereotype of Scottish weather's effect on gardening is indeed at
fault (or else, your stereotype of meditterranean climate ). Ceanothus,
and many other med plants, thrive in many parts of Scotland including
the NE.
North east scotland (where Aberdeenshire is) has the driest climate,
least cloud and most sunshine of any part of Scotland. Summer
temperatures are cool, but dry and sunny and the daylight hours are very
long. It's relatively low-lying, close to the warming influence of the
sea water mass. Much of the meditteranean also has very cold winters
just a few miles inland, and perishing winds: many of its plants are
adapted to drying wind and salt, conditions found in coastal
Aberdenshire. So, although swimming off the north east coast is utterly
unlike swimming in the med, there are enough similarities of climate on
land to support plants like ceanothus. I find NE nurseries a good source
of "mild coastal " plants, and ceanothus can certainly thrive there
(lovely examples in Crathes).
There can be a very icy east wind, but many Aberdeenshire gardens are
walled or hedged, for shelter. My guess is, the OP's ceanothus has
been too exposed to that cold wind.
The west coast of Scotland, from the south to even further north than
Aberdeen on the east, is warmed even more by the gulf stream. Much of
the Scottish west coast is almost frost-free, one of the mildest
climates in Britain with very long daylight hours in summer. Although
rainfall is high, it also leaches nutrition (good for med plants) and
rocky or sandy coastal soils can provide suitably good drainage. Many
coastal plants from hotter climates thrive in the sub-tropical gardens
all down Scotland's west coast.
