Can you plant asparagus 12 inches apart?
Dig the planting area at least 6- to 12-inches deep and about 12-inches wide. Space individual asparagus plants 12- to 18-inches apart for room to grow. If you are digging rows for your asparagus plants, they can be as long as needed for the quantity you're planting.
Does asparagus need to be divided?
Asparagus propagation by division is one of the most common methods. When production of spears slows down over several years, it is time to cut the root into pieces. Dig up the root in late fall after the last ferns have died back. Cut it into several pieces, each with plenty of healthy root attached.
How wide should an asparagus bed be?
Rows of asparagus should be at least 2 feet apart, allowing two rows to fit in a 4-foot wide bed. For every 8 feet of row space, you will need about a wheelbarrow filled two-thirds of the way with equal parts of the excavated soil and compost.
