Thank you Jim for that information, I will start feeding them. I have a mix of Dutch hybrids, S. African hybrids and some species seedlings from the BX. All are getting the same treatment. I would have to say that the S. African hybrids have responded the strongest. Some that had bloomed last x-mas, bloomed again this summer and are now sending out another flower scape. I wonder what they'll do when fertilized. :-) Linda Foulis Okotoks, AB Canada
