I bought some plants from a grower three years ago and I let them grow on for three years. This year over half the plants haven't grown there has been no sign of life. Does this mean my plants are dead or do you think they might do something next year.
This article will help determine if the plants are still alive: https://www.gardeningknowhow.com/plant-problems/environmental/how-to-tell-if-a-plant-is-dead-and-how-to-recover-an-almost-dead-plant.htm
As for your sandy soil, this should be fixed to improve the growing conditions for your plants. Without adequate soil, your asparagus plants cannot thrive. This article will help with that: https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/amending-sandy-soil.htm
I followed the directions on the package and it's been two weeks. Nothing is coming up at all. Should I just start all over? I did some reading and it said that the roots should have been damp. But they weren't, in the package.
You can gently dig down and check the roots. If they are pliable still, then they are still alive. If they are brittle, it is dead and you will need to start over.
You also need to make sure that you are providing plenty of water. The plant will need lots of water until it becomes established.
I planted 2 yr old crowns last year. They came up well both last year and this year. Do I cut the fern stems down at the end of this year or leave them to die off on their own? Thanks much.

Just moved into a new home. Great asparagus bed but it is completely overgrown with weeds and is 6-7 feet tall. What do I need to do to get it back in shape??
You may need to pull as much of it by hand as you can. There are some grass/weed selective herbicides available that can kill it in asparagus, but there are no organic solutions other than hand pulling. The asparagus will also need to be cut back this fall.
Can asparagus ferns stay outside all winter? Live in southeastern PA.
You may want to bring the plant indoors in your region. This article will help: https://www.gardeningknowhow.com/ornamental/foliage/asparagus-fern/asparagus-fern-care.htm
I have asparagus and want to plant seeds taken from my plants. Some are covered with red or brown skin. When do I pull them off the fern and do I open the skin or just plant the whole berry? Looking forward to your answer.
You can harvest the seeds during fall pruning. If you're starting them indoors, you would normally do this about 2-3 months before your last expected frost date. Then once they reach 6-12 inches, you can plant them outdoors, treating them like you would crowns.

I live in Northcentral Montana and we have a lot of wild asparagus in our area. I was able to collect some seeds this fall and was wondering how to proceed. The seeds would have dropped naturally had I not picked them, so I thought maybe I could scatter them in a prepared bed this fall, or do I wait till next spring. Any information would be helpful. Thank you.
