Courgette leaves turning yellow

Rob45Rob45 Posts: 14
Hi,

Some of the older, early leaves on my courgettes are turning yellow. They’re growing in standard bag-type multi purpose compost. The newer leaves look fine and there are courgettes forming, and the plant is growing. Does anyone know if the yellow leaves are a sign of a deficiency or disease or are they just old? Should they be pruned off?

thanks

    Mine are doing this too - went to Scampston Hall and Walled Garden yesterday and the courgettes in their vegetable garden looked similar

    I wouldn’t be too worried. I think it’s normal for some of the early leaves to go yellow and wilt. Mine certainly have. I doubt it’s mildew this early in the year.

    Agree, W54, the lower ones always go yellow and fall off mine, doesn’t affect the crop, so nothing to worry about.

    You might want to hold the leaves off the soil with a few strategically placed sticks to stop them rotting off, though, and don’t water directly onto the crown of the plant for the same reason.

    Mine are the same, I cut the yellow leaves off. You'll find there's lots of fresh growth.

    I grow my courgettes on old car tyres with plenty of compost,and for watering I cut the bottom off a plastic bottles push the bottle neck into the compost and fill it up and leave ti;ll the next day and fill it up again you can control the watering and you don't splash it on the plant,and I have found it successful and had good crops from them.

    Thanks all, they look better even after a couple of days so will keep them watered and fed and maybe nip off those yellow leaves.

    I understood that there is now concern that using car tyres for growing veg may result in the take-up by the veg of petro-chemical toxins as the tyres break down into the soil.  I believe Bob Flowerdew no longer does it.

    Resurrecting this old thread where I told someone not to worry about some yellow leaves on their courgette because I’m worried about some yellow leaves on my courgette!

    I’ve got 5 different courgette varieties in 50L tubs (black beauty, grisette de Provence, ronda di nizza, shooting star and golden zucchini). All growing really well (I’ve put them out too early, I know, don’t tell me) except for the golden zuchini which has very yellow leaves. It otherwise looks fine and is starting to produce male and female flowers. They’re all in exactly the same compost with some extra granular feed in there so I doubt it’s a deficiency. I grew the same varieties last year, all did pretty well and no yellow leaves.

    Any suggestions? Or should I take my own advice and not worry about it?
    Thanks

    Ignore. Have found the answer.
