Apart from sporadic volunteers upwind in my wild leeks patch, I started a patch of asparagus berries from my own plants by taking the whole dry stalks with berries attached, and placed them over the shaded plateau section of one of my compost hills/ windrows/ snow bank. That was the asparagus debris from fall 2024. I only covered slightly with leaf debris and a seedling commercial mix soil, so covering berries with about 1/2" of soil, days before the first snow.
That spot gets little sun, but enough, and the soil is fairly acidic, but rich in pigeon manure. Asparagus prefers 24-30" of rich soil and plenty of moisture in a cooler climate with slightly acidic soil. I'm zone 4a in Quebec at 850-1000', moraine, mountain mixed forest. It's moist enough with heavy clouds that wild orchids grow here.
I had to water all last year, and I am providing minimal watering this year -- and added a few more oak and maple leaf debris last week because the weather is unseasonably warm.
Sorry about the plastic soil bag -- when I started this patch 2024, I was on crutches so I bought soil in bags which I was able to maneuver, and that bag was the back of the compost pile of mostly kitchen scraps in various cardboard boxes, plus my pigeons helping. Those bags really helped me define the sides of the hill and most are now gone, but this one will have to stay until I can remove it without disturbing the seedlings.
I had to cover the seedlings with a wire cage that had 4"x6" holes on the bottom, so that my puppy didn't destroy them, while learning to leave the compost hills and grow beds alone. When I lifted the cages late summer, the few seedlings stuck to the cage got transplanted -- something asparagus really hate. They survived with intensive care but didn't come up this year. Lesson learned: leave them alone and don't waste time trying to save transplants.
I see some of our members here have had success with transplanting, and no doubt the roots weren't yanked out! I do hope to transplant most of this bed in fall to my son's house an hour away, preparing a spot in advance and digging down a whole foot before attempting to move these newbies in clumps. And protect them with a cage from the deer he gets visiting .
(We have agreed that when he takes over possession this September, I plant for the deer. Clover, yellow birch, a second apple tree, wild cherry, rubris, and plant buckwheat -- I digress but I do love the deer!)
