Which is correct, that male asparagus spears are fatter than female ones or the other way about? Thank you.

Hi Ruth, If you are still looking at asparagus crowns, The Diggers Club in Dromana has them. We were there last weekend and they had 3 varieties of crowns- Fat Bastard, Purple and Mary Washington. They do post also. Carly

I was given some asparagus ferns by our neighbour some months ago and want to plant them in the garden. They are about 8 inches tall. Can i plant them now? What are the soil requirements?

Hi Sir, firstly I live in Memel 98km East from Harry Smith and my asparagus does very well. I feel if you speak to the owner of the nursery next to the Spar he might be able to assist with plants. I have some 40 plants in my garden, all started from 4 plants. Enjoy your rewarding plants. They love the cold weather. And also seed well once they establish themselves. DO NOT BE IN A HURRY. Plant them away from the traffic even as an unusual garden separator. Do remember the bush can grow up to 1Meter high and some what wide. When it dies down leave it standing to almost the end of winter then cut them off and use for your compost. Enjoy the new venture. You are welcome to contact me.

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.
