Let asparagus go?

jennieboyer(8)March 27, 2012

Hi all - I am new to asparagus growing and want to make sure I am doing it right. I have planted the crowns, and they have put up the first shoots. Some of the shoots are almost 18" tall, while others are still fairly short. They have all ferned out. Do I just let them go now? I have read to cut them back in either early winter or very early next spring - do I let the shoots just keep growing taller? How tall will they get? And a question for next year - they "ferned out" fairly short - will they do this differently next season? In other words, will they get taller before they start to fern? Thanks in advance! Hope my questions make sense!

Cut them back after they turn brown. You let them grow because they are feeding the root crown by photosynthesizing. With healthy crowns they should get about 5 feet tall (or more!) Shorter ferns in fall may indicate that they need a fertility boost, but starting to fern while still short in spring is nothing to fret about.

Yep just as Bill said. Exactly when they will turn brown - fall or winter - depends on where you live gardening zone wise. For me that is usually early winter. Then mulch the bed well after cutting them and feed it well come early spring before the new shoots appear. Be sure to keep it well watered this summer and fall.

Cut the ferns off near the soil(even if you have to pull the mulch back to do it),when they turn brown.
Do not wait till Spring, mulch the bed at this time.
The cutting the stalk close to the ground, is to stop the Asparagus Beetle(Criocerus aparagi) from finding the old stalk & laying her eggs on it. The eggs hatch & they go to an all night & day lunch.You should burn old ferns if you have a problem with Asparagus beetle, if not you can compost it.The beetle can over winter in the mulch.
