Depends how much water you have put on over the last 2-3 months. The plant goes into dormancy in winter and the ferns die back later autumn/winter. Wait until late August and give it some fertiliser, put 100mm of compost on top and start watering it. It should start sending up spears after that. If not it might be dead. Google about growing asparagus.

In Northland when is the best time to plant and where can you get the crowns from please?

Go to New Zealand subtropical asparagus and the info is there when to plant. Bunnings generally have them in August to plant. Or internet seed selling website.

Can you grow asparagus in a bathtub and how many plants could you fit in? Many thanks.

I wouldn't do it. I think it has long roots that need more than a bath tub. About 2 plants if you do do it.

Can you spray for weeds around the asparagus in winter?

Three suggestions 1. Straight after you cut all the dead ferns off in winter spray the weeds - not recommended really you could kill the plants. 2. Give the ground a watering and pull the weeds out by hand - recommended. 3. Don't let the weeds grow much pull them out as they germinate. At the moment I have dozens of tomato seeds germinating from the mulch/compost I just put on my asparagus.
