Good well drained soil is best - you could make a hill or raised the soil a bit. Dig up the soil add some compost and or manure and let it break down into the soil before planting. Your planting time is next spring. Look on the internet "how to grow asparagus". There probably is some pests but I haven't had any in 2 years. Each winter cut off the deadish ferns and put on about 4-6" of horse poo or compost.

can I grow asparagus in cooktown fnq temp 16-35c if so what Varity

If you click the climate zone above and put in Tropics it says Plant May to July. Bunnings usually have crowns from Sept onwards. A hard job to grow from seed in hot weather. Read some of the comments here about growing them. There are only a couple of varieties really grown in Aust - any will do. Look up seed companies for varieties.

I am new to planting Asparagus seeds harvested from my garden. I live in the USA in Northeast (Rhode Island) I had a bumper crop of Aspargus this year and have harvested all the red Seeds: When and how should I plant these seeds?

I planted Asparagus roots I’m in the 3rd season now and so far I have picked two batches. I tried seeds and they didn’t grow. You maybe able to buy the roots at a place where they sell plants. The roots are kept in a refrigerator.

We have just moved to a little old (ish) cottage in Maldon Victoria and to my delight have just discovered asparagus growing in the back yard. It is not in a "garden bed" as such, but obiously once was. Grass has grown as lawn all around it and spears are popping up left right and centre. How do I encourage and look after it at this late stage (mid October)?

Lucky you!!! To an area about 1 & 1/2-2' around all the plants and between the plants give it a good watering. Next day pull all the weeds out. If you can, buy some horse or cow manure or compost and place about 3" thick over the top of it all. If the weeds are a real problem over the summer I would suggest during next winter when the asparagus ferns all die down, transplant the crowns into a nice prepared garden bed - then about August Sept each year put a 4-6" layer of aged manure or compost on them.
