Hi Delia, sorry not to have responded sooner, forgot to check.... looks like we both are looking forward to our first home grown crop of Asparagus next year and your suggestion about the wooded Chardonnay is also a very good tip. Happy gardening now that it may get a little cooler, at least here in Tasmania. Jen

Hi there, I have purchased and planted out 5 A crowns, but only 4 have produced A shoots, one has not produced anything? Any ideas? Jen

Should I cut off the tough ferny growth which is coming up now along with thick spears, or dig up those plants? Will they ever have good spears?

would i be able to grow asparagus in the sandy region about 50ks from frazer island .would i need to build up the soil or would that sandy soil suit.

I have just trimmed my ferny Aspagus which I now see is probably too early. There didnt seem to be anything but ferny growth. When does the crop grow? Will my crop grow although I seem to have trimmed too early. Thanks for your help

where does asparagus like to grow best full sun ,part sun and do they need to be protected from frost.

I actually live in Uruguay, S.America which has a temperate climate much like the south east US but not as cold. I planted some asparagus seeds last year into earth boxes and would like to know if I should plant them in their permanent bed this spring or wait another year. The ferns are beginning to turn brown and I've left them to nourish the roots. Any advice would be appreciated.

Hi guys After many attempts, we now have success with growing asparagus. In answer to previous question(s) I believe you can harvest many many spears from each plant, so they are well worth growing. My question to others is: I have read English literature that told of a practice of heaping salt on the plants after the fronds appear. I would not want to add salt to our saline landscape but wonder why this would benefit asparagus? Also is Autumn the time to add high nitrogen (organic & mostly home made) fertilisers? Lastly, I bought seeds & 2 year crowns on line. Gotta love that company! Thanks Kate

Hold off on fertilising during autumn especially with nitrogen and other soluble types. Fertilising is best done just before the plants enter their rapid growth phase, this is not only true for asparagus but for all plants although if your crop is flowers, fertilising during their rapid growth phase is also beneficial.

I was told that asparagus was a shoreline plant originally, hence the supposed saline affection. All I have done is mulch with unwashed seaweed from the beach. This provides excellent nutrition and so far so good. I'd be careful about adding salt, and seaweed seems the perfect solution.
