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.

I am about to plant a raised garden bed with Asparagus, I have done the research but am confused with the depth that the crowns should be planted. Would any of those that have had success give me a little advice. Thanks in advance - Lee

When do I cut down my asparagus ferns to prepare the bed for winter? At the moment – still quite lush and green. I’m from Chch.

Cut the ferns in late August and put compost or composted manure on it. Stop watering them now.

I have grown some asparagus from seeds and they are about two inches high. I really want to plant them in the garden now (because I remember to water my veggie garden but often forget to water the seedlings so I just want to get them in the garden so they are better looked after also they don't dry out so quickly there as well.) Is it Ok to plant them now and will they survive the Pukekohe/Auckland winter in the vegetable garden and all come up in spring?
