I buy my asparagus crowns from Green Harvest who are located in Queensland and sell their products, seeds and edible plants by mail order or if you live near them you can buy in person. They are an organic plant seller.

Hi, I planted an asparagus plant last year (2017) in July. Cut back the ferns in August this year (2018) and topped with compost. There are a few spears that have come through now. What should I do with them? Should I cut them back or just leave them? Thanks

I’m in Melbourne outer east, I have 6 asparagus plants from one and two years old. Only one of the newer plants has spears coming up from about 2 weeks ago. At this stage I’m leaving them to get stronger.

I will try again. Plant seed - one year old - a crown 1.5 - 2 inches. Two years old a few spears - pick a few thicker than a pencil - leave the one thinner than a pencil. Three years old you have a reasonable crop.

My asparagus is now two years old and already shooting. Should I crop and eat or leave alone and also should I put manure and compost on now before spring. Thanks

They say at 2 y o leave the ones thinner than a pencil - pick the bigger ones. Put the compost manure on now. Lay off the watering from end of May early June to allow the ferns to dry back a bit. Then in August cut the ferns and put the compost on and start watering Sept.
