Dear all, Thank you so much for your input on growing Lycoris. I did pot mine last year, because I trusted the friend who gave them to me (and I still do, he is a lovely person and a great gardener). I think it was a good decision to pot them, since I can better control when growing in pots, especially something that I do not have a lot of experience with. As I wrote, I did not expect these Lycoris to bloom with me this year. I do have L. aurea, but it has never bloomed for me, so you can imagine my surprise. Now that I saw some in bloom, I am curious to keep them growing. For now I decided to leave them in the same pots and treat them like I did in their 1st growing cycle. I will repot most of them next year, before they are to break their dormancy (first was Fawn for me, it showed the spikes already in August, 1 week after it cooled down). It might have worked out due to temperatures this year: we had a continuous +25 C for a few weeks in July-August (when they received no water), then it cooled down to +20 C or less and 1 week later I saw the first spike! You can imagine the joy I felt. This is when I soaked them in rain water and a few days later the other two showed spikes. If you want, I can keep you updated on how they do next year. And, I will gladly share some offsets, if anyone is interested (next year, when I will plant them in open ground). To be honest, I am glad to be part of PBS now, I can learn so much from you. I just wish we could have more interaction, other than just written emails. Now that David helped me to switch to my gmail, I should receive all your emails, so I will react more promptly. Thank you David. I wish you all a pleasant weekend. Now I will go get to planting, some of my own Narcissus crossings really need to be planted today.

In horticulture, related to fruiting trees, the benefit of cold to encourage bloom is not as one might imagine. Effective chilling hours is only in the range of 34°-48°F. Anything lower or higher does not actually contribute to the necessary chilling hours for bloom success. > > I suspect this is true for Lycoris, but it would be based on ground temperature as opposed to air temperature. Somebody needs to do a study on that. ;-) > > Everything I grow is in full sun, and the one disadvantage as I see it is length and quality of bloom. For instance, L. sanguinea, and many progeny with its parentage, can show scorched blooms in as little as one day in full sun with highs in the upper 80s+ (F). All plant growth is best in full sun, and this can be accomplished under deciduous shade and in certain locations near walls and buildings, where the foliage receives full sun in the winter and early spring, but shade takes over in the summer. > > Also, if you are not digging and dividing your bulbs every 7 years or so, bloom can all but disappear, even though you may have a huge clump of foliage. > > -- > Mr. Kelly M.

I grow many hundreds of radiata, elsiae, houdhyshelli, straminea, longituba, sprengeri, chinensis, squamigera, incarnata, aurea, with some of them in several clones and all flowers profusely every year. Some of them like radiata and elsiae are in full sun all year round, while other benefit from deciduous trees shade. Also I have grown from seeds sprengeri and have a flowering generation raised here, they took 7-9 years to bloom. I get little or no frost, just few days at -1°C (30F), only occasionally lower, but easily summer temps are 35-38 °C for weeks (96-100F) and no rain for months.Angelo PorcelliCentral Apulia-Italy > _______________________________________________ > pbs mailing list > pbs@lists.pacificbulbsociety.net > http://lists.pacificbulbsociety.net/cgi-bin/… _______________________________________________ pbs mailing list pbs@lists.pacificbulbsociety.net http://lists.pacificbulbsociety.net/cgi-bin/…
