Every leaf has white edges on my cucumber plant. I've tried googling the problem and mildew keeps coming up. But I don't think it's powdery mildew. It's the colour of the leaf rather than anything on the surface.

this is not powdery mildew. it is one or other of two things. it may be due to over feeding with liquid feed or giving it in too strong a form, not diluted enough. The other likely cause is too high a rise in temperature and then dropping too low. it is not from shortage of water. There is no danger to plant at present ,i hope this solves the problem.

Michael I think you may be right with the second suggestion. I was away for a few days and the heating was turned off. I have the plant inside my patio door for light, but the temp would have dropped as the house is very cold without heating on.
Thanks for that! You're a mine of information. I am actually in the process of ordering your book right now.  |
