Hi !

I have 4 Russian Vines (Fallopia baldschaunica/ Mile-A-Minute plant) that I planted a month or so ago in the ground on the corners of my new (bare) pergola. They have now reached the top (7ft) but the lower leaves are dying off.

It starts with red pigmentation appearing, it then turns "bleached" and the leaf eventually curls up and dies.

We can see no infection by any bugs, even with a magnifying glass.

Can anyone help please?

Thanks.

Hello Laura,

I suspect this dicolouration and ‘bleaching’ of the leaves on your Fallopia plants is probably due to a nutrient deficiency. I think it is probably a potassium deficiency, possibly a nitrogen deficiency. Can you tell me a bit more about the soil around the pergola posts, am I right to suspect it might have been quite poor soil? If it is a nutrient deficiency, try feeding the plants once per week with a balanced liquid feed.

Hope I have been of some help,

Regards, George.
