I'm an inexperienced gardener but this year I've dug a small veg patch
and put in a few young pencil-thin leeks. What sort of feed should I
use for these, and is there an optimum time to apply it?

All info gratefully received.

I normally water with a seaweed extract at first to get them going then
leave them alone. BTW are you a drill or hole planter? I'm the latter.
