It might be slugs or snails, try using something to kill or deter them.

Hi - I planted asparagus crowns in early September. I'm in mid Canterbury. Nothing has come up yet at all. Is it likely my crowns rotted or do I need to be more patient! Thanks

Read up about how to plant the crowns. They would only need a light watering each second day. Dig around one to see what is happening. Put in good friable soil not clay soil.

My 3rd year for asparagus, so first year picking with abundance. I seem to have a lot of tall skinny spindly hard shoots. I have been cutting them off. Why are they growing? Is it something I am doing wrong? Does the plant need them?

Mine are 3-4 years old. What I do now. Cut old ferns off late August (sub- tropical) then apply a few hand fulls of rooster booster from Bunnings per crown. It is only 4-3-3 organic fertiliser. I then put a 6

we have a asparagus plant that appeared in a place in our garden where we had not grown any last year produced 1 or 2 very thin spears that went to fern this year there is one normal size spear just coming up should we class this as 1st or 2nd year

If it germinated approx 1 year ago it would be 1 year old. You need to really look after this plant with compost/manures/fertiliser and regular watering. You won't produce a decent crop until the 4th year. Also I suggest you have 3-6 plants if you want a decent amount of spears each couple of days.

Google it - bugs that eat asparagus. Probably have to go out at night to see them. Then look for a spray, organic or chemical. Maybe don't use chook manure, or compost it before putting it on. I don't put compost/manure on until mid-late August.
