Hallo!
So, what do folks recommend for their D. petioliaris-complex planting media?
Cheers
Barry

I like 2/1 perlite/peat.

2 parts sand / 1 part peat
or
1 part sand / 1 part fine perlite / 1 part peat
The second seems to dry up into a light crusty, crumbly mix like almost like stale bread which I'm guessing is similar to the compacted almost concrete-like dry season soil that Lowrie describes for D. kenneallyi & D. falconeri.

Barry,2 part peat to 1 part sand,or 60/40 peat and perlite.I only use 50/50 when germinating seed.The nocks and cranys of the soil are important because they seeds germinate best when slightly covered.PM me your address.I'll send some seed your way.Petiolarissean

I have been using a mix of 2/1/1 sand/LFS/pine bark mulch and have been happy with it. Though I am thinking of adding an aditional part of perlite as the one plant I put in a mix with that seems to be doing better.

I've used equal parts silica sand and peatmoss with good success in the past. Now-a-days, I use perlite and peatmoss in equal parts, only because perlite is more cost effective than sand.  Homer |

I use, about 60/30/10, peat, sand, perlite.
Seems to be fine for all my petiolaris group. I grow them in a covered tank, on top of pots--so raised out of the water.
When actively growing, i find many white roots coming out of the pots growing towards the water!
Peter.

Hi Barry,
Mr. Lowrie recommends the latter of Petiolaris Sean's mixes for most(60/40 peat:perlite), and for D. falconeri and D. kenneallyii, he recommends 50/50 peat/sand.
I know one grower who is using 50/25/25 sand/fine bark mulch/milled lf sphagnum with great success. The sphagnum hydrates better than peat.
Cheers,
Joe

Gee, how observant am I. Yes, this was the friend I was referring to, lol. Which one plant was it, Travis? Cheers, Joe I have been using a mix of 2/1/1 sand/LFS/pine bark mulch and have been happy with it.

It was a falconeri TAHBWG clone. Since I have a near limitless supply of these they are always my experimental plants. SInce it was doing so well I also potted up my last batch of flasks in that media (ordensis, darwinensis, derbyensis IIRC) THey took to it well and showed less sign of transition shock. So I think I will be doing a full repotting one of these days (100+ pots, the wife won't be pleased)

So I think I will be doing a full repotting one of these days (100+ pots, the wife won't be pleased) Since you have so many, why don't you do a soil experiment (controls and replicates on the order of 8 or more each trial) and write up a page for the ICPS "How To" section. In my experience transplant timing and other environmental factors are as important if not more important than the soil mix as long as the soil mix isn't too heavy or too light. I'd put some plants in pure sand and some in pure peat to try to get some that don't do well. |

Hey John, While I have acces to a near limitless supply I do not have limitless space Right now my petiolaris set up is maxed out at 4 40L tanks (no more space for more tanks.) Each tank has room for 32 pots. After this weekends repot-a-thon (I decided to move everything into the 2/2/1/1 media I mentioned above) I have 110 pots of petiolaris complex and the remaining space is taken up by calycifida forms, some lowland Nep seedlings fresh out of flask and a few other heat lovers. My main method of media evolution is to put everything I have in what I have found works then experiment on a few expendable plants. If things go well for those then I make a full swithc and start over again. I discovered some interesting results with an experimental kenneallyi while repotting that may shape the next round of experiments. Once outside temps stabilize (been getting a few freak freezing nights of late) and I can move some material outside for the spring/summer then I may have room for another tank to play with. If I do I will shot to do a controlled experiment for ICPS/CPN. Cheers |

Hello all, I'm a novice when it comes to the Petiolaris group of Drosera but I have found that not all petiolaris sundews do well in, or require the same potting mix. I have grown a plant that was sent to me by Chuck Lyon as a hybrid, in pure Long fibered Sphagnum, without drainage, for about a year now. I have divided this plant twice so far. It needs dividing again.  This is a Drosera falconeri that I received from Bob McMorris a few months back in peat/ sand/ perlite with full drainage. Other plants of this species that I had in LFS, without drainage, are green and look terrible, though they have divided into multiple plants. All of my petiolaris Drosera grow on the same window sill inches from one another.  Take care, Steven Stewart |

Steve, it looks like you are off to a great start with the petiolaris group. Your plants look nice.
Have you experienced any dormancy yet?
Peter.

Peter,
Yes, all of my plants in this group have gone dormant except the single plant of Drosera falconeri in the photograph I posted. I'm glad the pioneers of this newly discovered Drosera group have shared so much cultural information, so the rest of us can play with them, know what to expect, and exactly what we are seeing, before killing the plants by overcompensating with improper cultural changes.
Take care,
Steven Stewart
