Is my Wisteria diseased?
Hello everyone! An avid gardener and veg grower now living in Dubai and trying to hold onto some species I'm fond of. I bought a potted Wisteria in Germany on a trip and brought it back to Dubai in August. Temperatures hit 45-50°C in summer and have now gone down to a very pleasant 30°C during day time and 20-25°C at night. It was doing very well in the pot and put on new growth even in that extreme heat. When I got around to putting it in the ground it seemed to stop growing and the leaves have now turned odd colours as if it's diseased. The soil quality is terrible so I've added manure and compost to my gravelled sweet sand. Do you think it's just a b it confused with the time of year and shutting down for the "winter" even though temperatures here are now indicative of a good summer in Europe or do the pictures look like it's got a bug of sorts? My gut feeling is that it looks unhealthy but I've no idea what may have made it go down this path after having been quite content in the pot of compost.
Any suggestions welcome!
