Hold off on fertilising during autumn especially with nitrogen and other soluble types. Fertilising is best done just before the plants enter their rapid growth phase, this is not only true for asparagus but for all plants although if your crop is flowers, fertilising during their rapid growth phase is also beneficial.

I was told that asparagus was a shoreline plant originally, hence the supposed saline affection. All I have done is mulch with unwashed seaweed from the beach. This provides excellent nutrition and so far so good. I'd be careful about adding salt, and seaweed seems the perfect solution.

I have eight Asparagus plants in the corners of my 3metre x 1.5metre vege garden beds. I bought them as seedlings from Bunnings and they have been growing well for the last twelve months or so and still doing well. I have harvested lots of spears so far, but now I am thinking of transplanting my plants all into one bed. Can I cut the plant into two and plant them without destroying the plant? At the moment they are well ferned up and look quite healthy and strong. Also is it too late to do this now coming into December? Thanks, Lucien.

What pest would not only nibble through the delicate seedling Asparagus frond but eat every bit of green? On checking this morning there is NO sign of any frond left and there is no soil disturbance on the surface of the big pot? I am still speaechless... Any ideas outhere and what do I do now, wait and hope for more fronds to grow OR compost the lot??? and yes should you be wondering I am the same gardener who submitted the previous question and mistakenly clicked on NZ but this is the correct location, I am in Tasmania..\

Perhaps cutworm? They do eat the entire plant if it's tender enough :O) I got the following advice from the Yates website and it worked for me: Cutworms are only active at night, so go out after dark with a torch and check for caterpillars at work.Prevent cutworm attack by placing small, open-ended plastic cups around plants or by wrapping plant bases with aluminium foil. (Start just below the surface of the soil).

For the fist time I recently purchased some seedlings of Asparagus, planted them into deep 420 cm HDPE pot and now read that they take 3 years before harvest? If this is true what is the quantity of one seedling at havest time?? One spear of Asparagus Or more??? And does it really take 3 years from seedling stage with 3 fronds? And what happens with the soil in a pot, all Ican do is top it up with say cow manure or similar suitalbe manure / compost mixes? Any help is appreciated as this is my first time growin Asparagus Thank you Jen (Tas)

Please check the info on this and other sites as there is so much to learn about asparagus. These plants are the ultimate gross feeders, they love fertiliser and water It will last up to 25 to 30 years if looked after properly. I believe that you only harvest the spears from the male plant and the female one's produce berries. Please contact me if you any more queries. I am in Burnie. Joe

I can attest to the compatability between pasley and asparagus. The parsley growing in and around the Asparagus beds - Asparagus is 3 years onle and the pasley self seeding after 2 years - is the healthiest and strongest of the parsely plantings that I have. (tas)

The transplanted ones will depend on how they were treated last year - whether they were left to build up energy reserves for this year. If you had plenty of spears grow into ferns then they should produce this year. Probably also depends how old the old crowns are. Last year while I was growing mine from 12 mth crowns to 24 mths I use to put about half a cup of fert in 9 L of water and feed them each month - only had 3 crowns. I also put manure/compost on in august. I have crowns that are coming up to 3 years old - that is from when seeds were planted - they have been shooting spears for a few weeks now - I have cut them back and manured and watered them. My seedlings which will be 12 mths old in Sept - I have not cut them back yet or put manure on them yet - will probably do that in about two weeks time. I have not watered them for the last month - they are not growing at the moment. As for manure - chicken is the richest in N followed by cow and then horse manure. I read the other day horse is about 1.75% N. Whatever manure you can get and add some fert if you like. We have had only one week of cool weather so far this winter - that is night temps down to 6-8 degrees.
