New courgette leaves are yellow

keithfinch · « **on:** June 23, 2020, 21:31 »

I have been growing courgettes for many years and for the first time the lower leaves of my young courgette plants are all yellow. Pretty certain its not a virus or mildew so... any advice on what it could be. I feed the plants with a high nitrogen balanced fertiliser.

Welcome to the forums

It's been an odd few weeks with weather. What is your watering regime like?

I'm also a little puzzled by your reference to a high nitrogen, balanced, fertiliser - what are you using? High nitrogen and balanced seems contradictory on the face of it. How often are you feeding, and are you following the dosage instructions? Sometimes an over fertilisation of one element can lead to the plant being unable to take up other elements.

Are the leaves pale yellow and struggling or bright yellow and otherwise looking good? My yellow courgette plants (�Soleil�) both have bright yellow leaves at the minute but are healthy (the green �Black Beauty� plants do not). I have had this happen in some prior years and have seen no ill effects.

A few of my courgettes and squashes are the same, I guess it's because of the topsy turvey weather we've had. I've treated mine to some chicken manure pellets and a few good soakings and I'm sure they'll pick up.

Hi Yorkie,
I am using Miracle Grow soluble firtilizer which has a high nitrogen content, which is supposed to be good for corgettes. I have since read that the problem could be caused by a shortage of manganese.
