  1. I have a love of science and as a result have been testing multiple methods of leaf pullings on Dionaea for some time now, this is a log of my testing method, results and conclusions. Introduction: I'm a student so cutting costs is one of my top priorities when taking cuttings, as a result all of my experiment was preformed using items that can be found in the common household(excluding a full spectrum CFL and a VFT:-P) as a result no chemical additives were used eg. Rooting hormones, anti-fungal powders .etc. All experiments were preformed over a three month period During said period progress was recorded at 1 month intervals Each factor/method was preformed with three leaves Once the traps turned fully black (in all methods) they were removed to prevent fungal growth Taking pullings: Pullings were taken early February from a plant which was bought fresh fresh out of dormancy Pullings were taken by un-potting the VFT and "pulling" downwards on the leaves so a section of the rhizome came away each time All pullings were taken from the same two plants All chosen leaves were of the same size and health Procedure: Method 1: Pullings placed on Peat Moss The leaf Pullings were placed in dents on the surface of a pot of boiled peat moss(dent used to make the most possible surface area of the underside of the leaves be in contact with the peat moss, boiled in an attempt to kill off fungus spores and bacteria) The pots were placed in a tray of Rainwater approximately 30cm away from a CFL Each pot was covered in cling film Method 2: Pullings placed in Long fibre Sphagnum (LFS) The leaf Pullings were placed in on the surface of the boiled LFS with as much of the underside of the leaves in contact with the LFS as possible The pots were placed in a tray of Rainwater approximately 30cm away from a CFL Each pot was covered in cling film Method 3: Pullings placed submerged in Rainwater The leaf pullings were placed in glasses of boiled(then cooled) rainwater (boiled in this case in an attempt to kill bacteria and algal spores) The glasses were placed approximately 30cm away from a CFL Each glass was covered with cling film Results: Method 1: Pullings placed on Peat Moss This method resulted in the shortest amount of time before fungal growth was seen(at the 1 month interval) No successful strikes were seen before all pots were consumed by fungus(possibly due to cling film causing stagnant air which sped up spore germination) Method abandoned at 2 month mark when all leaves were noted to be dead Not a method I've had "lots" of success with in the past as well Method 2: Pullings placed in Long fibre Sphagnum (LFS) Method shows promise as 2/3 had strikes Fungal growth occurred only after 2 month mark Between month 2 and 3 two leaves were killed by fungus(one with a strike and one without) By the end of month 3 the remaining leaf had formed a plantlet Method 3: Pullings placed submerged in Rainwater By far most successful No maintenance required (ie. no topping up water) apart from removing dead traps %100 strike rate No fungus seen(due to submersion) Small amount of algae seen during month 1 but it was left alone Conclusion: After preforming all three variations of leaf pulling I found the most successful to be the technique of placing pullings in rainwater. The LFS strike that did survive had grown larger then all of the plantlets from the Submerged method, but a conclusion on size of plantlet can not be drawn as this could be an isolated case. From my own opinion the submersion method is also the easiest, no potting or watering, just stick it in a glass of boiled and cooled rainwater(not to mention it's the cheapest) Method of acclimatising Submerged plants to emmersed(yes it's a real word) state After plantlet has reached approx 1cm in diameter remove it from the glass and place it on LFS or peat (very wet) in a pot with cling film over the top Over the course of a 2-3 weeks pop holes in the cling film At the end of the three weeks you have air-hardy little plantlets After Notes: Two weeks on from the end of the experiment all 4 of the successful strikes have formed plantlets with small traps, the ones from the submersion technique seemed to take a week off of growing to acclimatise. I would like to see how long one on the plantlets could be left in water before being acclimatised as growth was much faster pre acclimatisation, buts that's a whole other experiment for a different time. I hope my long rambling report can help someone in some way eventually. - Niall FM

  3. Hi everyone, I'm struggling with my D. paradoxa: I want to multiply this lovely plant, but it doesn't work! I tried leaf cuttings and even flower stem cuttings, in sphagnum, in water. Nothing... Did anybody succeeded with this particular species and has a trick to share? Cheers Vincent
  4. Hope someone can shed some light on this for me... As of yet all the new leaves that have come up on my plants have been simply folded in two, as if hinged with the hinged part moving out to form the part with tentacles. Now one of my plants (still small only ~4 inches high) is growing leaves that are coming up in spirals, is this a leaf or a more mature way of sending them out. Could it be something else like a flower spike (surely the plant is too small). Any ideas or help would be great.
  5. How common is fasciation in Drosera as I think a slip up with mine has caused some. Some of the leaves ended up with damage because of enviromental change so I'm 70% sure it is not from a virus... fingers crossed. Images are alittle fuzzy sorry about that but the leaves in them are at least twice as wide as the other 'normal' ones. Are these indeed exhamples of Fasciation?
