I have 10 Jersey Night asparagus spaced 18x18" in a 6x3' bed. They were raised from seed, allegedly all-male, planted out 3 years ago and harvested for the first time this season. BUT two of them turn out to be female & have a fine crop of berries. I want to get rid of them & replace with males. (Sorry ladies - it's not about anti-feminism; just that I don't want a bunch of unwanted babies choking the bed.)
SO... how do I do this?
A) How get rid of the unwanted female plants: Digging them up (when dormant) might seriously damage the roots of their neighbors. If I let them grow next spring but keep cutting the shoots off at ground level will the plants die, including the roots?
B) How establish new plants (MALE only - how will I know?) I could grow these from berries harvested off the unwanted females but I'd have to wait 3-4 years to harvest from them, with no guarantee they'd be males - and would they be able to form good root systems anyway, planted close alongside well established 4-year olds? By the way I've already found that I have more success growing from seed than buying roots. But how can you know you're raising a male plant when you germinate seed?
Maybe I should just yank or otherwise kill the unwanted plants and accept empty spaces in the bed.
What do you think YOU would do?
