Q.
I see online some people cut the roots of asparagus before planting. I did this
last year. Is it a good idea? I was thinking of planting asparagus at the base
of fruit trees. It makes them easier to plant, but are there consequences?

Your question is about cutting the roots of asparagus and what consequences
might occur. I must guess since I don’t have much experience with that. They
are both deep-rooted, so I don’t think there is a problem with irrigation and
spear production provided the roots are covered with clean (no rocks) soil when
replanted. It’s best to use clean soil directly above the roots. Rocky soil
covering the roots may lead to the growth of “crooked spears”. The crown of
asparagus will have to grow some new roots for storage.
There is one major problem. It has to do
with interference between the fruit tree and the asparagus. After the asparagus
has been harvested, the shoots are allowed to “fern” up so they can gather
energy for next year’s production and the roots can grow. These ferns can be 5
to 6 feet tall when they finish growing. I could see how these might grow up
into the branches of the fruit trees. Ferns can be cut without any problems.
Cutting the ferns will interfere slightly with the number spears you collect in
the spring, but not much.

A minor problem (maybe??) is the amount of light
available. As the fruit trees get larger, they will create more shade. The
ferns will not collect as much sunlight in this location. Regarding the
asparagus crowns competing with the fruit tree for “root space”, it’s true but
not a huge problem if you don’t put too many crowns at the base of the tree and plant them where they will get light in the future. I
think you are fine with 3 to 4 crowns planted there about 18 inches or so apart.
