Dear All, For Alberto I looked for the notes about fertilizing from Sir Peter who grew and hybridized thousands of Nerine sarniensis and found the following two quotes: "N. sarniensis and its hybrids must have a cool winter with plenty of water, particularly in the first half of their growing season when they are making their foliage. Temperatures above about 13C except in direct sunlight have been found by the New Zealand researchers to be unfavourable to leaf and bulb growth and this was confirmed by my own experience. I dare say that N. bowdenii will take a good deal of fertiliser. With the species I would go cautiously. With N. sarniensis very cautiously indeed. They pumped the plants up with feeding in New Zealand and I believe the immediate results were spectacular followed by devastating virus attacks later on." This second quote was specific to N. sarniensis hybrids "6. Pests and diseases. Heavy fertilisation releases the virus which is dormant in these plants. As I did not fertilise at all, I only once or twice saw virus in any of some thousands of plants. Research in the wild showed that these plants grow in nature in some of the world's poorest soils. Attempts to push them for rapid maturity from seed or cuttage and largest size flower heads or two spikes per bulb resulted in the near collapse of one large commercial operation from virus. I only once lost a bulb from insect attack when mealybug somehow got inside a bulb and my efforts to destroy it destroyed the bulb as well! Insects are not a problem with these plants. My greenhouse would never have passed a phytosanitary inspecton because it was also used for certain things compatible with the Nerines, i.e. a winter store for Citrus: Passiflora edulis, Hoya and some scandent Epiphyllums which housed several enemies which did not trouble the Nerines." Sir Peter Smithers All of the contributions have been so interesting and helpful. There appears to be a lot of variation in how these are grown. The Nerine filifolia on the Wiki from Bill Dijk looks very different from the ones from Rhoda and Cameron. Could it be something else and if so what? It is really nice whatever it is. One of the advantages we have with our wiki is that we have such a lot of knowledgeable people in our group. If there are mistakes I hope everyone will speak up because we want what we are presenting to be accurate as people are finding the wiki pages by searching with Google. Mary Sue
