Hello, I'm just starting to delve into the world of container Japanese Maples, and my 1st year Corallinum graft has just arrived in the mail. After some research, I have potted it in a "gritty mix" of chicken grit, sphagnum moss and varying sizes of pine nuggets: I am a little worried about the mix, as it seems awfully loose--should I be adding more organic matter such as top soil? I had some mixed in there initially but it seems to have just settled to the bottom of the pot after I tried running water through it, creating a muddy sludge that was actually trapping water inside the pot, so I created a second batch of only the loose materials based on another JM owner's posting. The general advice seems to be that Corallinums, and Japanese Maples as a whole do not like to sit in wet soil and the loose mix allows the roots to breathe and spread out, but the consistency of it reminds me of just plain old pine mulch and I do wonder if the JM is going to be able to absorb the water and nutrients it needs. Any help on this will be much appreciated! Secondly, when I removed the JM from its nursery container, the root hair system seems to be holding on to the dirt in the container pretty vigorously--it's in essence a dense-ish block of roots and dirt. Based on what I've read here and elsewhere on the internet, it seems like prying the roots free to prevent the tree from becoming root bound is recommended, however, I'm wary of damaging the root system and further stressing the JM after its journey through the postal system, so right now I've just sunken the whole block, roots and dirt and all, into the loose pine/moss/grit mix. Should I just bite the bullet and try to pull the roots free? My last question regards some dryness in the leaves: It appears that there is a faint white edging on some of the leaves (more visible in the second photo above,) along with a few dried out spots. Some preliminary internet research suggests that this might be just stress. The stems on the leaves look pretty rosy and healthy, although the leaves themselves feel a little--for the lack of a better word, papery, not totally dried out, but definitely thinner and fragiler than what I imagine new spring leaves should feel like. Do these leaves look alright to more experienced eyes? Thank you for any advice you can offer! I love this little guy already even though it's a little scruffy from the trip here and I just want to do anything I can to make sure it thrives!
