Cuke pot sizes

[robfosters]

My cukes have now hit about 3-4 inches tall. They are still in the pots they were sowed in (3inch). Should I know be potting on a 5 inch pot?

Is potting just a case of transplanting when you feel they are outgrowing their current homes.

The best way to tell when plants are ready to be potted on is to look at the holes on the pot bottom. If you can see roots then you need to pot on into the next size pot (unless that is a very small step then go up 2 sizes). When the plant is filling a 6inch pot I usually put them into 10litre flower buckets

Mine were still in their module tray and I have repotted them tonight into 5" pots asthey were getting too big for anything else.

I would have thought at 3" - 4" tall they were ready to move on. I'm expecting to do mine this weekend and they are not as tall as that, I have one good true leaf formed.

I turn the pot upside down, with the plant itself between my fingers, and then knock the pot rim on the edge of a table so that the plant comes out of the pot - and into my hand.

I can then see how well the roots are developed - I like to see plenty of roots around the outside of the rootball, but not enough that the whole thing is even close to becoming a mat of roots.

If its not read I slip the pot back on and then turn the plant the right-way-up again.

If ready then I pot on 3" - 4.5" - 6" (the books say 1" at a time, but I can't get my chubby fingers in to firm around the repotted rootball so I got up in 1.5" steps)

Alternatively, go through the motions of potting on but if you find the roots are not as developed as you expect that put it back in its original pot for another week.

Isn't it a bit early for cucumbers. I haven't even sown yet.....

I sow mine mid March to raise in a conservatory and then plant out into cold greenhouse in May

I think that would be too early for a cold greenhouse, or for outdoors!
