Hi all its the 1st time iv grew leeks and i think iv made a mistake with them already!I started them in modules early march 1 per module and although they are looking great at the minute im thinking there isnt enough depth for the roots to grow properly am i right!!!

Allow them to grow to the thickness of a pencil.  Make a narrow 1" ish deep 6" ish hole where each of them are going to grow (with a dibber or metal bar).

Carefully remove the leeks from the modules and plant them - individually into the holes.  Some people say shorten the roots by a half and the leaves by one third, but this is not a universal practice.  Drop the leek into the hole and fill with water.  The water will wash soil into the holes and cover the roots.   Easy peasy.     Cheers,   Tony.

If they are big enough to plant now, then I would, assuming you have the space available.

If not I would half fill a deep tray (or pots) then put the modules on top, and settle in with a bit of compost over the top, so they can make deeper roots.
They are easily split up at planting time

This is how im doing mine this year and keeping my fingers crossed as i was late sowing them.

Me too ....apart from waiting until they are pencil thick.  I must have done better this year as they are not too bad for this time with quite a late sowing....not biro size but substantial enough. 

They went in today, I dibbed to about 3 inches.

I can already taste leek and spud soup

Pencil thick? Mine are not moving.... They've been given more space this year in their (similar to a) cat litter tray but still the little blighters remain little.

Biro sized ones work ok when they're planted out

Mine are like long matchsticks. Think I'll feed them something........

[Paul Plots]

I plonked a slow release general fertiliser in with mine. They are healthy looking but slim.

What happened to all the fat ones my dad used to grow?
May be I should have sprinkled them with pelletted chicken manure the way he used to.

Most plants benefit from being grown in modules when it comes to transplanting but it`s nigh on impossible to get module grown rootballs down a hole. You could always use collars to achieve blanching though.
