Bonsai Buxus - What's happening
Good morning everyone,
I’m here to ask for some help in figuring out what’s wrong with my plant.
It’s a Buxus harlandii; for about a month now it’s looked like the photo. It seems to be alive because there are a few small shoots (which then turn yellow straight away). I can’t get the soil to dry out anymore; I use the sensor visible in the photo to monitor the moisture levels and keep it between 15 and 60. It gets a couple of hours of direct sun in the morning from about 7 to 10 am and then receives light all day; it’s on a covered veranda so the temperature is between 10 and 20 degrees, and I air it out occasionally by opening the windows. Small round black spots are starting to appear on some of the leaves. I’m at a loss as to what to do; I hope you can help me.
Thank you in advance
