Hi everyone, I like to know why is it that my sango kaku maple tree that is growing in a pot gets scrotched easily whereas my neighbor who grows this tree in the ground doesn't scrotch? Also, I like to know does sango kaku produce any red leaves in the fall?
scratch + ? = scrotch? I suspect that fall coloration will vary with soil and climate, but my tree colors mainly toward yellow tones in fall.
Australian usage may be quite different, so I'll defer on the true definition of the word "scrotch". I must say, however, that I am most impressed by the international flavor of this forum - Australia, Italy, U.S.A., Canada, Ireland - almost makes me want to burst forth with a chorus of "We Are The World" :)
lol... I'm so sorry, poor spelling. whis4ey is correct - It's scorch. That's a lovely tree you got there whis4ey.
I find that most JMs in pots have a greater chance of scorching than those in the ground. One reason is that it is more difficult to regulate the moisture in pots. Of course, watering patterns, placement (sun/shade), and high temperatures ultimately determines what will scorch. Down the street from me is an in-ground Sango Kaku specimen in full sun that is scorched each year. My Sango Kakus in pots are kept in part shade and have never scorched. We reach 100+ F/38+ C in my area during the summer months.
Plants in pots dry out quicker, plus the soil can warm up or cool down more than plants in the ground. For example, some of my Japanese maples in pots are already starting to leaf out, but my JMs in the ground are still dormant. In short, potted plants generally are under a lot more stress unless watered often and protected from temperature extremes.
Gotta love the comments from around the world. It would be interesting to compare soil and temperature conditions in another thread.
