Hi: I've been getting into trees this past summer and learning as I went. So understand that I bought a potted coral bark Japanese maple tree, a container plant, during the summer (rather than Spring or Fall) & planted it in the ground with soil ammendment (Miracle Glo tree & shrub soil mix, if memory serves) and poured on a Miracle Glo liquid mix made for freshly planted plants to help them start. I don't recall for sure, but I doubt I went around the root ball hunting for potentially girdling roots. The tree is planted in an exposed full sun location in Zone 6, southwestern Kentucky. So, not everything's been done right. On the other hand, the tree is mulched, we've had frequent rains through the summer & it's had occasional supplemental waterings to prevent extended dry periods, but not keep it perpetually water-logged. When bought, the leaves were rather dark green. It would've been planted around June 2'nd, '09. Here's what it looked like at the Nursery: I apologize for posting links instead of photos; I couldn't figure out how to post a photo into a post. I tried different code tabs from Photobucket.com and 'Preview Post' and it didn't work. Now, months later, the leaves vary from moderate green to yellowish. It's my understand from online searching could be due to mild sun-burning (especially a first year plant where the root mass might not support the leaf mass well; here's a thread on the sun-burning issue), nutrient deficiency (iron, manganese or zinc) or excessive alkalinity making a given nutrient unavailable to the plant. It's my understanding some seasoned horticulturalists can make a limited judgment call from looking at the leaves to see the patterning of the chlorosis. On a good note, it's not defoliated. I can't say it's grown, but it's mostly held its own. Here are photos taken yesterday. You can try this link to go to the Photobucket Album; if that doesn't work, I've included direct links to some of the photos. I hope to get a soil sample sent off soon, but that's going to take awhile, and the results won't match the soil right around the tree since it had the Miracle Glo soil added. A friend told me the yard soil has substantial clay and ought to have plenty of iron. Thoughts, folks? Richard.
