Two of the asparagus plants I put in to the specially built raised bed seem to have survived. They look so different to each other! ?! One looks thin and spindly with a feathery leaf on top, whereas the other looks like an asparagus shoot !?! I've been told that you shouldn't try cropping asparagus until the plants have been in for 2 years, otherwise you might damage the plants ability to reproduce stems for next year.
