Try one of the all male asparagus types that don't produce
seeds. You'll get thicker spears and better production. I have a patch that I started with 25
plants and it has already produced 17+ pounds in a only a little over 3 weeks.
Last year I also planted some of the new Purple Passion asparagus. It's not all male, but it's supposed to be sweeter and more tender than the regular green asparagus.
They recommend digging a trench about 8 inches deep to
plant it in. Till the soil up first and then rake it out to make the trench. It's important to get rid of perennial
weeds before you
plant, so if the ground hasn't been prepared yet, it might be best to wait till next year. I was planning on starting a new strawberry bed this year, till I read you should have the bed prepared ahead of time, so now I'm going to till up the area for the bed and keep it clean through the summer and then
plant it next year.
When planting asparagus in the trench, spread out the roots, and fill the soil about halfway up the trench and then fill in gradually as the
plants grow till it's back at ground level.
It's also good to supplement the soil with manure or compost. I think I added rock phosphate and greensand and tilled them in before I planted my all-male asparagus.
