Yikes, my error our climate is zone 6a. If someone could provide me with the Answers to the above questions I would be appreciative.

Check the planting time from the planting calendar in Asparagus page. Also google how to grow and harvest it.

I just received 6 asparagus roots, with 4” growth on top. Can I plant them in my enclosed garden area or should I keep them near a window, indoors? It is still warm to hot, in my zone 9 area, of Southern California.

I assume you mean 6 crowns, a bulb with roots coming from it, looks like a spider. Plant them out but pay attention to watering.

I've just purchased yesterday, 4 of the 2 yr crowns from Guilford Garden Centre in Perth. This is my first time growing asparagus so I'm very curious, have lots of questions to ask......Now one of them already has a pencil size spear, can i be greedy_cut that off and eat it? I've potted them in a 60cm deep big pot temporarily while I'm setting up a new raised bed for the asparagus, how tall should i have the raised bed? If i establish them well this year, can i be harvesting small amounts next year? Thanks guys!

We purchased some 2year old crowns 4 years ago, it was so very tempting to cut some of the bigger spears. But our patience paid off. Now we are able to cut good sized spears every 2-3 days.

Hi Mai, Here is an article you might find useful. It has some info on when to harvest https://planyourpatch.com/how-long-does-it-take-to-grow-asparagus-from-seed/

Here are my suggestions. 1 Pick a spot that has sun all day. 2 Dig a bed that is about 4' x 4' or 1.2m x 1.2m for 4 plants or 1.2m x 1.8m for 6 plants, 2.4m x 1.2m for 8 plants - I would recommend 6-8 plants, about 300mm deep. 3 Put a border (sleepers) around it, either 200mm or 400mm high (2 sleepers). Garden sleepers (hardwood) where I live are 2.4m long x 200mm high x 50mm thick ($20). Fill it up with soil/composted manure/compost and dig it over a couple of times. Buy some rooster booster fertiliser from bunnings and apply about a 2l ice cream container to the soil and mix in. Go on the internet and google how to plant and grow and harvest it. 1st year pick a few of the thicker spears, 2nd year a few more and then 3rd yr you can pick all. In future years a tip, stop or cut back watering end of April, cut all the ferns off end of August, apply a 2l container of rooster booster and 6

a bit hard to stop watering in Perth at this time I might knock it down at the end of summer and try to pick a few late spears then

I stop watering at the end of April and just leave it. I cut back the end of August and apply fertiliser then water and 4-6 (??)
