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, am living on a smallhold close to Swakopmund in Namibia.Plot owners plant successfully green asp on rather salty soil.I would like to try white asp on 1/4 ha land.Soil is soft and fine. We never have frost and have to water since we have no rainfall. Preferable thick stemms since i would like to market already peeled stems.Please advise type of young plants and where to buy against what costs. Regards, Johnny.

I am also wanting to grow about half a hectare of asparagus and would like to know whether you managed to find any plants and where from? Regards

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.

I am a first time grower and am preparing the ground with compost only in a mound.what else should I add? SHEEP MANURE OR CHOOK.DO THEY LIKE LIME?

Asparagus prefers a high ph of 7.0, so my gardening books state, so yes liming likely will be needed. Can you test the ph of your soil? I give mine horse manure and sheep pellets - I have no source for hen poo, but I cannot see any reason why that would not be good for them.

I have eight Asparagus plants in the corners of my 3metre x 1.5metre vege garden beds. I bought them as seedlings from Bunnings and they have been growing well for the last twelve months or so and still doing well. I have harvested lots of spears so far, but now I am thinking of transplanting my plants all into one bed. Can I cut the plant into two and plant them without destroying the plant? At the moment they are well ferned up and look quite healthy and strong. Also is it too late to do this now coming into December? Thanks, Lucien.
