Does asparagus need full sun or partial sun?
Site - Full sun is ideal. Asparagus needs at least 8 hours of sun per day. Since asparagus is a long-lived perennial, do not plant where trees or tall shrubs might eventually shade the plants or compete for nutrients and water.
How deep do you plant asparagus roots?
Plant crowns deeply to protect them from the cultivation needed for annual weed control. Dig a trench of about 12 to 18 inches wide and 6 to 8 inches deep. If digging more than one trench, space the trenches at least 3 feet apart.
Can you plant tomatoes near asparagus?

Does asparagus need to be staked?
Support the Plants
You can support asparagus plants with tomato cages, trellises, or stakes and wire/twine: Tomato cages – you will need a cage for each asparagus plant (not for each spear!). As the plants grow, they can lean on the cage for support.
