I will try again. Plant seed - one year old - a crown 1.5 - 2 inches. Two years old a few spears - pick a few thicker than a pencil - leave the one thinner than a pencil. Three years old you have a reasonable crop.

My asparagus is now two years old and already shooting. Should I crop and eat or leave alone and also should I put manure and compost on now before spring. Thanks

They say at 2 y o leave the ones thinner than a pencil - pick the bigger ones. Put the compost manure on now. Lay off the watering from end of May early June to allow the ferns to dry back a bit. Then in August cut the ferns and put the compost on and start watering Sept.

If you water them they will shoot in winter. Mine did last year and I didn't have many spears in Spring. I stopped watering the end of April this year. Cut the old dying ferns off about two weeks ago. Will put horse manure and compost on them mid August and start watering start of Sept.

I have asparagus roots that I have stored in sand for about 5 years. Do you think they would grow or do you think they would be dead?

My guess is they are dead. Plant them in Sept and see what happens. If they didn't grow and die off each year then what has sustained them all this time.

Mindful that its a little early to cut back asparagus shoots, but when you do ,keep in mind that they are useful in getting rid of nematodes if you dig them through effected areas

wouldnt it be dangerous to grow asparagus in your garden with young children likely to eat the berries?
