Large cabbage

Nothing, as yet.

How often have I said to you that when you have eliminated the impossible, whatever remains, however improbable, must be the truth?


Perhaps it was a UFO after all!

I always thought that was Spocks quote! PAULW's reply seems feasible as all brassica seed looks the same!

I wish that was the case. The plants I'm talking about are in my back garden but I also share an allotment and the ones there from the same seed packet, sown at the same time, planted out at the same time are 7" tall and showing every sign of being the compact ball-headed cabbage they are supposed to be, so I'm still looking for an explanation as to why the others are so large.

Is that reply not "eliminate" by the quote above ?

the weather? Is your allotment on an exposed site?I know everyhting vaguely cabbage related in the polytunnel has gone nuts.There are usable pak choi in there that were only sown a couple of weeks ago....

There are quite a few things that will affect the size of leafy plants like cabbages. Too much nitrogen or conversely not enough nitrogen will have an effect.

Shade.........
Soil temperature...........
Micro climate...........
Soil type..........
Acidity/Alkalinity.......
Moisture levels.........

........... to name but a few.
