What is the best way to store the remaning chokes that I have just
dug?
They soften so quickly when left exposed.

no real way to store them. That's why the storebought chokes are so
close to inedible. Try to eat them as soon as dug.


I have heeded the advice and screend the soil surrounding last years
planting to minimize the spreading of the vigorous plants.

good idea. I used to have a vigorous patch myself, until the deer found
it.
But in time I found that the surrounding lawn crept in. It is best to
place a solid grass barrier, and mulch heavily with chips. Basically,
same thing as with asparagus.
