Neutral Marscott On May 14, 2013, Marscott from DeKalb, IL wrote:

I planted a young Autum Blaze Maple tree last September, it has buds set but as of May 14 2013 the buds have not swollen or opened. The upper branches are brittle and snap easily however a scratch test on the main trunk shows green....what do I do to help?

Positive slyperso1 On Apr 7, 2009, slyperso1 from Richland, MI (Zone 5b) wrote:

Beautiful tree; bright read seed in the spring, much brighter than red maple; nice leaf in spring and summer; no significant disease or pest, but I had some borer; Amazing fall colors, almost luminescent yellow/orange/red.

The trunk is a little thin when young, thinning canopy helps decrease the wind resistance the prevent splitting of breaking; the bark is thin and deer can damage it easily.

Autumn Blaze does very well in Edmonton zone 3b. It is definately not only hardy to zone 5a. This tree has amazing fall color but depending on the year, can turn color very early (is very sensitive to temperature drops). The color does last a long time. There are a couple on my street that have held their color for longer than a month! Does not mind the neutral-slightly basic Edmonton soil.

Neutral stevation On Apr 4, 2006, stevation from Pleasant Grove, UT wrote:

I was told this maple was more tolerant of Utah's alkaline soils than other red maples, but I see the description above say it likes acid-to-neutral soil. I have one doing very well, one pretty good, and one clearly chlorotic. I need to figure out if there's something I can do about the chlorosis. They've all grown well, and I don't have any problems with them breaking as the previous writer said. Mine were never staked and have survived wind storms and are quite thick after four years.

Negative lydiasophia On Jul 15, 2005, lydiasophia from Eugene, OR wrote:

While this hybrid is meant to be stronger than silver maple, I lost two out of 4 trees (about 2" caliper) which 'snapped' about 4 feet off the ground during a gusty day (not a storm by any means). Their growth rate is phenominal, but they became so top heavy they were unable to support their canopy.
