my new asparagus bed

Every crown took off - I have a bed of the cutest tiny asparagus spears shooting skyward.

very small crowns

This order was a disappointment. Half the crowns were tiny, with as few as 3 roots. I planted them 2 months ago and out of 25 crowns, 15 have sprouted. I put all the smaller ones together in case they would have to be replaced and it appears they will since none of them are showing signs of life.

So sorry to hear that! At Territorial our products are backed by our full guarantee! We want you, our customers, to be 100% satisfied with the seed, plants and supplies that you purchase from us. If anything you buy from Territorial proves to be unsatisfactory, we will either replace the item (if available) or refund the purchase price (up to 1 year from purchase). Contact our customer service (Monday-Friday 8AM-5PM Pacific Time) at either 800-626-0866 or Hope the crowns that are growing continue to do well!

Very small plants

Just got mine in the ground several weeks ago. I was totally bummed by how small the roots were. Smallest I've ever gotten from mail order. Will update this review once I get to taste them in a few years and see how they perform in the garde.
