Ridge cucumbers - how tall?

[Farmer_Gyles]

they're best part of 4ft tall now and still growing
looking really healthy - growing in tomato growbags in the greenhouse (got more in pots outside but much smaller) - plenty of flowers, no baby cucumbers yet - and they look like they're still shooting upwards
should i cut off the top to stop them growin upwards?? if so, at what height?
all i know is they are ridge cucumbers - can't remember the variety (mental note to self to keep seed packets!)

It's up to you to manage the growth - you decide how much height you can cope with. Given enough food and water they can be very vigorous growers.

cheers - think i'll decapitate them now and hopefully they'll put their energy into some nice cucumbers
