Growing Asparagus is quite easy. I have grown asparagus from seeds and that too in a pot! It is quite a hardy plant and tolerates cold winters and dry spells as well. Just don't overwater it. This year I am planting the crowns from my potted plant in a raised bed along tomatoes and coriander as both the plants discourage each others pests.
