Sorry you're having this problem Pete. Here in Florida, we have something called pocket gophers. They burrow underground, leaving occasional piles of dirt at the surface. They feed off of the roots of vegetables. I am berrying fencing all around the perimeter, 1 foot deep, to prevent them getting in to my asparagus. It should stop the bunnies too! Don't know if this help but I wish you luck in solving this.

Hello. I planted a bed of asparagus last year and they grew beautifully. I did not harvest any stalks and the bed is full of ferns. I live in Los Angeles, where the weather has stayed quite temperate, even though it is now December, The ferns are still green. I'm concerned they may not die back fully in our climate. Can I cut the ferns down before they brown without harming the plant?

I stop watering in mid Autumn and cut my ferns off end of Winter. This gives them time to die off. The first year I watered and fertilised through winter.

Google what varieties you have in the USA and try one or ask at a nursery.

I have a patch of purple passion which are tons sweeter than asparagus and they are great producers! We also have a patch of tried and true Millennium. We planted 10 crowns of each about four years ago, and they are enough for our family of 4 with some to spare. I'd love to freeze some and I'm thinking about starting a second patch of about 20 crowns to have some for preserving. Also, remember that when you plant your crowns, you don't harvest from them for two years. Just let them go to fern. They are quite lovely in a herbaceous border with other perennials. These are a gift to your future self! :)

I planted Asparagus last year. It has done very well and I fertilized,mulched when need to , or cut ferns when need. My question is, at the end of December, a few Asparagus began popping up, and tips purple. Is it ok for them to pop up that early?

You generally cut ferns off end of Winter and pick new spears for 2-3 months in the Spring, then let the ferns grow again to feed the crown for the following year. If the weather is warm enough they will keep sending up new spears until end of Autumn. I just cut mine off for a quick feed over the last month of summer. Mine are 5-6 years old. I'm in Australia - sub tropical.

When you buy crowns does only one shoot grow from one crown? It looks like from pictures that there is more shoots coming up if your planting them 8 to 12 inches apart? Since we live in central coastal California is it best to go to a nursery in town for buying the two year old crowns?

The crown will produce many spears. As it grows it produces more and more over the years. Plant 2' apart. Buy 1 or 2 year crowns.

Asparagus is perennial and will bear for around 20 years.
