Pam,
I have been told by a nusery man specialised in Japanese maple
that most Japanese Maple need some shade or another. This cause me
great concern as I have spent a great effort in improving my soil for
the last few weeks and went on a spending spree on japanese maple. I
have planted Bloodgood and Osakazuki plus many others to come and I
have been using the list of sun tolerant maples you have shown me as
guide for any purchase.
Few points he made
1.All japanese maple need some shade in Australian condition.
2.Laceleaf culstivars are less sun tolerant then the others.
3.You need to have a shade tree before any japanese maple can be
planted.
I am confused even more when another nursery man told me that shade is
optional. Both claim to have 20 years experience in cultivating
japanese maples.
Fact and observation
1. I think point 2 is wrong as I have seen many laceleaf under full
sun condition without any problem.
2. Temperature range I am in. Winter never goes below 0 C (32F),
summer is always between 30-40C (86F-104F), 1 or 2 days of 45C (113F).
3. My garden is South - East facing.
My question is
Would my sun tolerant maples more likely to be in trouble next summer
?
If i have to plant a few tree that can be used as a shade ? Which
would be the best one to go for ? (One that grow fast so I can
continue my Maple dream, not too big as I don't have a big garden and
also would have minimal impact to japanese maple that will be planted
close to it in the future).
We are in the middle of autumn right now, was told by the nursery that
I have missed by a few days for seeing great colors of japanese maple.
The strange thing is that all my japanese maples are still green ?!
(Autroperpeum, Sango Kaku, Osakazuki). What's a good explaination for
that ? (Too much water ? as suggested by J.D Vertrees's book)
Thankx again. I feel like a worrying parent.

Pam,
A new question regarding the maple and the sun. I have an unfortunate
luck of having my garden facing the sunset every day. Can you tell me
which caltivar of Japanese Maple will be better at facing afternoon
sun ? Thankx heeps.

There are lots of J. maples that tend to be more tolerant of a late sun
location, certainly the straight species (Acer palmatum) and its
redleafed cousin, Acer palmatum 'Atropurpureum'. Most of the disectums
(laceleaf cultivars) can adapt to this location although you may
experience some scorching in their first couple of years. They outgrow it
quickly as they become acclimatized. The following link will provide a
good listing of others:

The ones you definitely want to avoid are those with variegation or very
golden foliage. Just make sure to keep the trees well watered through the
summer heat.
