Wait until the ferns are fully brown and dormant to maximize the next year's harvest. https://www.gardeningknowhow.com › edible › vegetables › asparagus › cutting-asparagus-foliage-back-in-autumn.htm Tips On Cutting Back Asparagus Plants - Gardening Know How Once you have cut the asparagus back, add several inches (10 cm.) of mulch to your asparagus bed. This will help to smother the weeds in the bed and will help fertilize the bed for next year. Compost or well-rotted manure makes an excellent mulch for asparagus in autumn....

We actually live in Sierra Leone. We have had our plants for several years. We keep watering them through dry season (Mid Nov-April) so they won't die. Will they die if left alone or just hibernate? Also, should we trim fronds off at all or bend them over to reseed (they have multiplied on their own fairly well). And when should we add compost?

I cut my ferns off late winter (August), apply compost and fertilise and water well. I pick all spears until the end of Oct (2 mths) then I let the ferns grow. I water each week. I do another picking in Feb for 3-4 weeks. Then I let grow again. I water until end of Autumn. Then let the ferns die back. Cut off end of winter. I cut my ferns off water really well. apply 100-150mm of compost and fertilise and water well. Spears usually start shooting straight away (early Sept). I live Sub-tropical Australia.

Hi, should asparagus be staked. Every time my asparagus matures the stems always blow over.

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.
