My asparagus bed, productive over about 15 years, is doomed, as it is overwhelmed by perennial weeds. My plan is to coax a crop out of it for this season (coming up nicely) and next season, but in late summer to dig out thoroughly one end of the bed so that next spring I can put new 1 year plants into that end. May/June, I will again be able to crop the old plants.
Then gradually extend the new patch, with the idea of never having a season without mature or maturing plants, until I have a clean bed of productive young plants.
Does anyone know if asparagus is like, say, roses, in that new roses never do well in a patch where roses have been removed?
