Q.Black Hamburge Grape 3 Years Old

Zone London UK | ianDanderson added on July 24, 2022 | Answered

Can you help please. Why are the leaves turning yellow and brown and it is not August yet. Is it over watering? Or a disease? If the latter what do spray / treat with? Many thanks in advance. Ian Anderson

It could, certainly, be a bit of both! Be sure that the soil has a chance to dry out quite a bit between waterings. Anywhere between 10-15 cm should be let to dry out to avoid issues with bacteria and fungi.
