Leeks are always a reliable, normally trouble-free crop


although recently Leek Moth is proving a real problem in some areas. Thankfully it has not arrived at Roesmoor yet.

Our leeks were transplanted this week following the lifting of the early potatoes, caught by early blight.

Leeks are normally sown outdoors in seedbeds for transplanting later. However, if conditions are not good during germination, results can be disappointing.

At Rosemoor we sow our leeks in 10 inch pots in the glasshouse 


and transplant later into the open ground when they reach about the thickness of a pencil. We normally sow in the second week of April; this proves more reliable than the traditional method of sowing outside. Sow between 50-75 seeds per 10 inch pot for ideal sized transplants.

Plants are eased out of the pot and carefully teased apart,

picking out the best.

I find it easier to plant the young leeks if the roots and the tops are trimmed. The roots are trimmed to 1 inch and the tops to 8-9 inches.

If the roots are trimmed, they go in the hole easier and by trimming the tops they are less prone to the birds pulling them out of the holes before they get established.

Trials over the years to test whether cutting the roots and tops damages the plants have shown a marginal improvement if the plants are NOT trimmed. But I have not noticed any difference in practice if the plants are trimmed and it is so much easier and quicker to plant.

Wit a bit of luck we’ll have leeks by Christmas.

As a welshman, now living in Leicester, I would like to grow some leeks as seen in a container, as I have decking. I have a spare 2 foot diameter container. Would it be too late to plant leek seeds now, and how many plants would I be able to put in the container?
