Growing white asparagus at home

You have probably seen, or at least heard of, white asparagus.  There are no varieties of white asparagus, but the good news is that you can make any variety of asparagus grow some white spears at home easily. 

Normally to make asparagus white the grower will blanch the asparagus by putting a bucket or something over the emerging spear.  As it grows it has no sunlight, meaning it stays white.  This is simple to do at home if you are growing asparagus.  The end result is a much sweeter asparagus spear.

Often people use any of the green varieties to make white asparagus.  This works well.

Purple varieties of asparagus are much sweeter than green to begin with.  Which means white asparagus made from a purple variety is very sweet, it's quite remarkable.

Making white asparagus at home

This year I decided to make white asparagus using a purple variety.  The end result is asparagus that is incredibly sweet and very tender.

One of the spears grew a little large and started to lift the bucket.  This bent the largest spear and let in a little light, resulting in white asparagus with a tinge of colour.  

Not to worry, this was still very sweet and unlike anything you can buy from the shops.

If you grow asparagus give making some white asparagus a try.   Just put a bucket over the soil where the spears will emerge, and remember to check it every few days.

I only do a few spears per plant so as not to weaken the plants too much, but I am probably being overly cautious.  I am sure commercial farms make a lot more white asparagus per plant and have no problems.
