Hi mike as I explained on my last post about transplanting crowns into a new bed, at this stage the once I transplanted are still dormant which I expected it will take I think for next year to get a some spears.The other crowns that we have in the same bed are sprouting through and looking good .By the way I thought asparagus shoot through in spring .Anyway I put lots of horse manure on all of them however I think cow is better .What do you Think?

The transplanted ones will depend on how they were treated last year - whether they were left to build up energy reserves for this year. If you had plenty of spears grow into ferns then they should produce this year. Probably also depends how old the old crowns are. Last year while I was growing mine from 12 mth crowns to 24 mths I use to put about half a cup of fert in 9 L of water and feed them each month - only had 3 crowns. I also put manure/compost on in august. I have crowns that are coming up to 3 years old - that is from when seeds were planted - they have been shooting spears for a few weeks now - I have cut them back and manured and watered them. My seedlings which will be 12 mths old in Sept - I have not cut them back yet or put manure on them yet - will probably do that in about two weeks time. I have not watered them for the last month - they are not growing at the moment. As for manure - chicken is the richest in N followed by cow and then horse manure. I read the other day horse is about 1.75% N. Whatever manure you can get and add some fert if you like. We have had only one week of cool weather so far this winter - that is night temps down to 6-8 degrees.

I trimmed my asparagus bushes about three weeks ago andI put about 2-3" of compost on them. Ten days ago I put 2-3" of horse manure and another 2" of compost on. In the last week I have had approx. 20 spears from 3 plants.

Is asparagus perennial or annual
06 Jul 17, John (Australia - temperate climate)
Asparagus is perennial and will bear for around 20 years.

I transplanted a few old and new crowns 27/6/17 in Gisborne Vic into a different bed wondering how long before they settle there and was it the wrong time to replant them and will they produce any asparagus this year .Thanks for any comments anyone can post .Tony

Tony - a friend of mine has had asparagus in for 4-5 years. He moved them last year and they are doing fine. Asparagus is dormant during the winter months and this is the time to do it. You probably could have waited another month or so but I don't think it will do any harm. Hope you dug the soil up good and put some manure in the garden bed. During July and August put some more manure / compost on top of the garden -- 4-6".

I have a question about asparagus. I am planning to plant some crowns soon. Can I plant other veg in this bed whilst the asparagus is dormant? If yes, presumably something not deep rooted like lettuce? if yes, any other suggestions?
19 Jun 17, Mike (Australia - temperate climate)
The crowns will start shooting August -Sept. Very little time to grow something. Depending on where you live - you would plant crowns Aug -Sept and put a good cover of compost / manure on top. This supplies the crown with nutrients for growing - you wouldn't want other plants use the nutrients up.
