Defalotus Posted October 9, 2011 Report Share Posted October 9, 2011 Davion, you're a troll. Idk what you expect to gain by antagonizing these guys. I have seen you do a few experiments myself on a few different sites and 2 things are in common in all of them...theyre weird and never get finished. Good job Mantrid and Mobile! 3 Quote Link to comment Share on other sites More sharing options...
petesredtraps Posted October 10, 2011 Report Share Posted October 10, 2011 I can only draw a conclusion from what I have seen with the pictures,and it seems VFTs seem to grow well with a pine needle mix. So, for those of us that would like to give it a try when repotting next year, where would one aquire the pine needles? Please don't say "gather from the forest floor" there is nothing like that near the chav capitol of Doncaster. Quote Link to comment Share on other sites More sharing options...

They are common in the UK, so there's likely to be some around near you. Quote Link to comment Share on other sites More sharing options...

There might also be some in the other woods on the east side of doncaster, sandall beat wood, shaw wood, sandall park and theres a big wood to the west of sprotbrough.

mantrid Posted October 22, 2011 Author Report Share Posted October 22, 2011 (edited) Update 22/10/11 25/09/11 22/08/11 The colour variation is very evident now between these genetically identical plants. Could the growing medium be playing a part? Is it down to the amount and type of insects being caught or is it something else. For those not following this exp all conditions were kept the same exept the growing medium, and of course being outside I had no control of the prey caught. Interested to hear other peoples theories? Another interesting experiment for the future ie control the type and amount of prey being caught to see the effect on growth and colour.

Defalotus Posted October 22, 2011 Report Share Posted October 22, 2011 Maybe pH of the medium also? Idk but theyre looking great. Seems like the plants in PNs are a lil bigger than the others. Quote Link to comment Share on other sites More sharing options...
mantrid Posted October 23, 2011 Author Report Share Posted October 23, 2011 Seems like the plants in PNs are a lil bigger than the others. Yes but not a big enough sample size to make draw a firm conclusion. The one in the 100% pine needles is also quite small making me think it may be related to amount of water, as the pine needles drain easily. So the one in 100% needles is not getting as much water as the rest. It may be the opposite for the 100% peat which will contain more water than the rest, maybe too much with the result that its affecting its growth. Ensuring that each medium has the same amount of water absorbed into it will resolve this. But that would be difficult to do. Differences may also be down to the amount of prey caught. Again stricter control is needed to test this, either by controlling exactly the amount of prey taken by each plant or using a large sample size to average out any differences due to amount of prey taken. The only firm conclusion that can be drawn from this at the moment is that pine needles dont hinder the plants growth and can work effectively as a structural element to the medium similar to perlite. 1 Quote Link to comment Share on other sites More sharing options...
Defalotus Posted October 23, 2011 Report Share Posted October 23, 2011 Have you checked the pH of each different medium? I'm just curious. Quote Link to comment Share on other sites More sharing options...
mauro Posted October 24, 2011 Report Share Posted October 24, 2011 I'm thinking that since VFT's grow in pine barrens in the Carolina's, that an ideal soil would be some combination of peat, sand, and pine needles. The media you're using in pots A-C probably mimic their "native" soils to some degree. Obviously, the areas they're from have a huge variety of soils, so I'm generalizing. Anyways, I think you're onto something here, and I will likely be adding some pine needles to my mini-bog to minimize the peat I'm using. Great looking plants to the both of you!

mantrid Posted December 18, 2011 Author Report Share Posted December 18, 2011 I am stopping the photo updates until spring as there is no growth taking place at the moment just a bit of die back. Probably have another pic at the end of feb beginning of march time. Thanks to everyne for the feedback, comments and suggestions so far.

mantrid Posted March 27, 2012 Author Report Share Posted March 27, 2012 (edited) New season and as its a nice day I have taken pics of this continuing experiment. Over the winter the growing media has sunk and become over grown with moss so I have refreshed it by removing medium from the top and replacing it and adding some to the bottom of the pot to bring the plants back up to the rim of the pot. One thing of note is that within the pine needle pots at the bottom there was noticable decomposition of the needles. In the 100% pine needles there appeared to be some anaerobic condition at the very bottom as there was that noticable sulphurous smell coming from it and the needles were saturated, no longer possessing the free draining ability they had when they where not decomposed. Will be interesting to see what effect this decomposition is going to have on the plants this season. 27/03/12 22/10/11 25/09/11 Edited June 9, 2022 by mantrid Quote Link to comment Share on other sites More sharing options...
mantrid Posted March 27, 2012 Author Report Share Posted March 27, 2012 Have you checked the pH of each different medium? I'm just curious. Sorry for late reply. No I didnt check pH. I did have some universal indicator paper somewhere but have misplaced it. When I find it I will check the pH as it will be interesting to see how much difference there is particularly after all this time. 1 Quote Link to comment Share on other sites More sharing options...

mantrid Posted March 30, 2012 Author Report Share Posted March 30, 2012 Hi, great thread and read, really inspirational and I'm liking the results you are getting. Yes me too. Looks like needles can substitute for drainage additives like perlite and also some of the peat as well. The biggest plant so far is in 50:50 peat and needles. However, as mentioned earlier this experiment needs to be conducted on a larger sample size for more accurate data and some other variables need controlling such as prey capture and saturation of the medium.

FlytrapRanch Posted April 25, 2012 Report Share Posted April 25, 2012 Can I use the pine bark? Many people are trying various alternatives to sphagnum peat moss. I'm currently experimentally growing a Venus Flytrap in a mixture of (by volume) 1 part silica sand, 1 part chopped pine (or any evergreen) needles, and one part evergreen bark pieces. Because this mixture drains freely and dries a little too fast, I plan to add 1 part by volume of carefully desalinated coir (coconut husk pith) which has been repeatedly soaked for 8-10 hours and drained (perhaps 8 to 10 different soakings) to remove the soluble mineral salts that are almost always present in coir.

sabryberty Posted April 25, 2012 Report Share Posted April 25, 2012 (edited) Thanks, I wanted to try it with peat moss and pine bark ... or peat moss, pine bark and perlite, and always leave the saucer full of water... Have you ever try to grow VFT with only live sphagnum? Edited April 25, 2012 by sabryberty Quote Link to comment Share on other sites More sharing options...
FlytrapRanch Posted April 25, 2012 Report Share Posted April 25, 2012 (edited) Have you ever try to grow VFT with only live sphagnum? Yes. I don't like it. Live sphagnum often resents in hot weather the bright sunlight that Venus Flytraps love. In hot weather, especially if one's climate is dry like mine is, live sphagnum moss grows better in shade, but Venus Flytraps don't.

mantrid Posted May 1, 2012 Author Report Share Posted May 1, 2012 (edited) Update 100% Pine needles suffering a bit. I think it may be that the needles are mostly dry as they cant wick up the water and the very bottom is saturated and anaerobic. Both conditions are not favourable for the roots. 01/05/12 27/03/12 22/10/11 Also had to share this great sunset from yesterday. We have some good ones over the summer but this is the best this year so far Edited June 9, 2022 by mantrid Quote Link to comment Share on other sites More sharing options...
mantrid Posted May 1, 2012 Author Report Share Posted May 1, 2012 I will take this exp a bit further this year. The 50:50 mix looks very good so based on that I will set up a larger sample size to compare of 10 plants in this mix against 10 in a typical 70:30 peat perlite mix. Also if I have sufficient plants of the same size I may also do a 50:50 perlite peat mix just to see if its that extra drainage/aeration of using 50% needles rather than the needles themselves ie will 50% perlite work as well as 50% needles.
