Leek "problem" ?

Why don't you want them to grow if there is a bit space?

if you want the space,trancefere them to some containers,you could always pick them them as young stir fry fodder,or the compost bin.

Leeks move easily. If you don't need the space leave them be, if you do, move them elsewhere or eat them.

The problem is the anticipated size of them. If sort of normal leeks then they just stay where they are. But the mammoth leeks are supposed to be somewhat bigger, and at present the available space would simply be insufficent.

If the number remains at 4 - no guarantee as they seem to be making a bid to take over the world. I may have a solution. A small area of a few turnip did not germinate and 2 could remain where they are and 2 could get transferred to the "turnip" bit. I sowed additional turnips at the weekend but about double the number elsewhere.

As said I treated the sowing of them as a bit of a "joke", the seed is about 8 years old and they never managede much previously. The expectation was "They had their chance and are not viable." Germination was not the expected result.

I can see them thinking "He didn't think we would make it, now lets show him how big we can get." Anyone read Jack and the Beanstalk? I have visions of that, but a leek not a bean.

My tendersweet carrot seed fresh this year has managed 4 and I suppose about 40 seeds were sown. I have (at present) 4 mammoth leek seedlings from say 15 seeds that were 8 years old.
