I have new 5'X5' Jasmin Espalliers. The leaves started turning brown and falling off the day after the nursery planted them. We then drilled holes in bottom 4" gravel then dirt and added saucers. The discoloring stopped for a few days and now it started again. There is new growth but a lot of leaves fall off every day. I water in the center only every 5 days. Is this too much or to little?
Could the problem be acclamation to the new enviroment? They are 15 gallon plants and have been growing for about 6 years (I am told)
I am puttng a few images here also.
Thanks so much ANYONE
