Sounds like you live in arid desert country. If so it might not grow in those conditions. If you have better conditions than desert you could try. Google about growing it.

I just received 6 asparagus roots, with 4” growth on top. Can I plant them in my enclosed garden area or should I keep them near a window, indoors? It is still warm to hot, in my zone 9 area, of Southern California.

I assume you mean 6 crowns, a bulb with roots coming from it, looks like a spider. Plant them out but pay attention to watering.

I live just North of Houston, Texas (20 miles) and I wanted to know if there was any way that Asparagus can be grown here. If so, what is there name or names?

Work out your climate zone from the blue tab above. Then check asparagus and look in the calendar to see what month you can plant or google it..

Hi Mike... I'm in zone 9b, as well. I'm wondering if you decided to plant asparagus.... and if you did, how did it work out for you? I just bought crowns and hope to plant this week. I have a spot that is cooler than most of my property. Wish me luck!

I put crowns in last summer and cut the canes down in the late fall. I now have first asparagus in March. Should I let them grow and not pick them?. No frost here. 1200 feet up and maybe 4 miles from the ocean in California. Fog at night in May-July but sun during the day. Warm to hot fall.

We're taking a break and there will be delays processing comments over the holiday season. Happy Christmas and Happy New Year!

Here in South Carolina, my asparagus grow April-Oct. So you may need to let them store food for 6-7 months. Clemson Extension says let the ferns grow with out cutting/harvesting spears, in July cut the ferns back & harvest new spears. So I guess you could cut them back a week or two before you want to harvest the new spears. I, however have not tried this .
