While my comments do not pertain specifically to Lycoris, I think planting depths are only a guideline and are not specific in all cases. In the harsh climate of NE Calif and N Nevada, my friends and I have found that we often have to plant something deeper than most anyone would think a sane person would consider in order to see a bulb last from year to year. Colleen NE Calif our winter lows have ranged from mid teens to -32F. Two years ago it was -22F, but this year we only got to the single digits. -----Original Message----- From: pbs-bounces@lists.ibiblio.org [mailto:pbs-bounces@lists.ibiblio.org] On Behalf Of a vbeek Sent: Monday, June 04, 2012 11:37 AM To: pbs@lists.ibiblio.org Subject: Re: [pbs] Lycoris Planting Challege!

After reading several mails about preferred planting depth of Lycoris I'm curious about what depth this may be. Aad
