I have a patch about 1.5m x 1m and I put a few stakes around the edges with 2-3 ropes up the stakes to keep them tidy.

How do I start asparagus from seed in the fall? Do I sow directly into the ground or start indoors? Zone 7b Thank you!

It suggests to plant Nov Dec. Start them in pots or trays. They are very fine little seedlings and need close attention with watering. Some sun, some shade during the day until they are a few inches high.

I want to know if I can get two years old Asparagus crowns.

Probably not - if so probably expensive. In Australia a 9 mth crown is about $10 - a 2 yr old probably $30 and you would need 3-6.

I bought and planted 4 (2 green, 2 purple) Bunnings asparagus seedlings in a very large trough/planter. I have very healthy looking plants (look like dill) about 45 cms high. Do I Just leave these or is there something I should do. Thanks.

Just water and fertilise them. Will take 3 years before you start to produce a reasonable crop. Read up about growing them.

Leave them to grow. You can stake them if you prefer. Once they die off, trim off the dead bits. Definitely mark where they are, as they will probably disappear. Do not harvest for at least 2 years.

One 6b - Bought crowns in late spring and they were misplaced.until now August. They are not dried out and I'd like to salvage whatever is possible. If I plant them now ANDif they grow, the season will be over and cold by October. Should I refrigerate the crowns and maybe wait til spring to plant or go ahead and put them out now? Also, would it be of benefit to use innoculant to stimulate them, individually pot them indoors under grow lights and gently transplant to an outside bed in spring? What makes sense?

Thank you. I cut down the ferns because they were browning. Thought it was correct. That asparagus like cold and frosty weather, do the early emerging spears not get burnt by frost at -3C?
