I've grown courgettes in containers this year but the yield wasn't as good as last.

The leaves started to turn yellow so I top dressed the containers with well-rotted manure but this didn't really help.

Does anyone know what would have caused this?

I've cut all the yellow stems and leaves off today - will that help?

the yellow leaves are either caused by Magnesium deficiency or Nitrogen deficiency or maybe a disease. A picture would be useful to see.

Hi,

I have grown courgettes for the last five years or so. I don't grow them in containers though. They are a very large plant and I suspect that a container may not give them the space and moisture that they need. The leaves of mine tend to go yellow and get a mottled appearance, but this has never affected the yield. I think this is caused by some sort of virus, but I am not sure. I grew 3 plants this year (planted a good few more, but the seeds were old and I did not get good germination). We are just getting to the point of the year where we are a bit fed up with courgettes Smile
I give mine a bit of tomato feed a couple of times during the growing season and tend to dig in a bit of manure before I plant out, but other than that I don't look after them that much.

Hope this helps a bit for next year.

Anthony

Hello
I can confirm Anthony's comments. I've grown courgettes in containers and in the open and I abandoned containers after one season-useless. I also get mottled leaves but it doesn't affect the yield. This year has been only OK for courgettes. I'm usually inundated. This year we had a dry spring/early summer and courgettes do enjoy the rain (as do the slugs which feast off them). It was not until the late summer rain that mine really recovered.
