Dear Japanese maple lovers, I don't know what I'm doing wrong! In early April this year, I bought two ten years old JMs - an Acer Mikawa Yatsubusa and an Acer Autumn Moon. They're both giving me some grief and, after perusing many forums over here (Europe, USDA zone 7 or 8 depending on whom you ask), I have not found out what I am doing wrong, if I did not read the trees' signs right or if I'm just plain stupid - please have a peek at the two photos attached. The details: - Purchased in containers 2nd week of April - Pots Ø 45cm with fairly organic soil and some grit so as to provide drainage - Added a little low nitrogen fertiliser in the soil mix - Wooden terrace 2nd floor facing south-west - Direct sun exposure from 09:00 - 11:00 and 15:00 - 17:00 - No exposure to rain - This year May, July and August 1-2 weeks with up to 37°C (23° at midnight) and stormy winds more suited to the Philipines, very unusual over here - Watered daily at the exact same time 1l, on those scorching days twice per day - Moved both plants as close to the terraces' windows/walls to reduce wind exposure - 9th July both plants showed brown leaf tips - 20th September both had very many fairly brown leaves, mostly away from the house; particularly the Mikawa had lost fairly many leaves on two branches - 23rd October the Mikawa has buds emerging on several twigs on those branches that dropped most leaves So, did I "love them to death" by overwatering them when in July I detected a brown leaf tips, not knowing it could have been damage from the hot winds, sometimes blowing hard all night, too? Did the soil I bought contain the verticillium fungus? The climate here should(?) to be good for JMs, from what I can see on other inner city terraces, balconies or rooftops; but maybe this year's insane weather was responsible - and then I added my fair share of rookie mistakes? Also, how often should I water potted JMs from November - February? There is no garden shed or garage where I could put them during the dormant period : ( Any help or suggestion would be so much appreciated!
