Germinating Sundew Seeds
« Thread Started on 11 Jan, 2007, 13:44 »Lets discuss how to germinate Sundew seeds.

I have only tried germinating the seeds indoors as I live in an apartment. This is what I do...

I treat my sundew seeds like how I treat my nep seeds. Place them on top of wet chopped up sphagnum moss and midst them with a water spray. I mix a few drops of plant hormone in water before spraying on the seeds. I guess it still works if you do not have plant hormone. Do not cover the seeds with sphagnum moss. Just place them on top of the media.

I then place them in a very humid environment. For me it would be my covered terrarium. I give them 16 hours of artificial light a day. Humidity is above 80%.

You could use seed trays that you can buy from nurseries and garden centres in Shopping complexes. They trays have a clear plastic cover with some holes on them. This helps to keep the air inside humid.

I also place my pots of seeds on a tray of water so that the sphagnum moss is always very wet. Try to mimic the environment where they came from, and usually where the parent plant is thriving, the seeds will grow. Every once in a while I spray water on the medium and replenish the water in the trays.

I have not tried germinating seeds in a shadehouse or outside in the garden. Hope other members who have done it please share your experience.

I am still trying to figure out what better ways to improve my process. Would be great to learn from the rest of you. « Last Edit: 12 Jan, 2007, 18:07 by David »Link to Post - Back to Top LoggedMy WantlistDavid

When that happens they might not be able to grow out of that hole in time to receive the light that need to grow. The seeds only provide them with limited food to sprout. If they are stuck in the gaps in the moss, they might die.

Once my seeds germinate I usually transplant them to their "home" so to speak, which is a mixture of one part sphagnum peat and one part perlite.

On top of the potting media I place a thin layer of chopped up sphagnum moss. Don't like the black colour of peat mixed with white perlite. Eventhough these materials are sterile, they look a little dirty. so the chopped up sphagnum moss covers that.

Always have a tray of water at the bottom of your sundew pots. They need their soil to be very wet unlike nepenthes that can take drying out for short periods of time. Neps roots will rot if you always soak them in a tray of water. Anyway it is more important for your sundew ****es when they are so tiny, not to let the soil dry out.

Also if you are placing the seeds under artificial lights, make sure it is only a few inches from the pots.

It is good to spray the pots with water using a mister once every 1-2 days. It give fresh air to the media top and sprays away algae spores. I have a few pots that I did not spray water on and they are place too far from the lighting. A thick layer of algae has grown on the media and I think this blocks the seeds. No germination on those pots.

One more thing. Sundew seeds seems to germinate slower for me compared to nepenthes seeds. Sometimes my nepenthes seeds will sprout within 3 weeks. All my sundew seeds take at least 3 months to germinate. Only my D. capensis (red) seeds germinate in 1 month ++.

« Reply #2 on 11 Jan, 2007, 19:38 »I used only Sphagnum moss to germinate sundews. Soak chopped sphagnum moss , lay them on a tray (without holes), pour some water until the moss is soaked in water, try to make the surface flat. Sundew seeds are really tiny like powder, just sprinkle the seeds on top of the moss as evenly as you can, or else you will end up plants grow together and you'll have difficulties in tranplanting them later.
Place them at a bright place. Be patient, after seeds germinated, you may move them under sun, I did that for my sundew and they seem to like it. But be very careful, the media could dry out very fast which I experienced before in one very hot day, luckily still managed to save a few plants. Remember to also get something to cover on top to prevent rain. Rain water will flush away everthing. But this is only my way, I think the best place to germinate seeds still in terarium where everything under control.
I found seeds being soaked in water germinate faster. Let's see how true is this. Link to Post - Back to Top LoggedTSDavid

« Reply #3 on 12 Jan, 2007, 13:13 »Oh, forgot to say... use distilled or RO water if possible when watering the potting medium for the seeds.

I did not carry out an experiment and have a controlled group of plants to see the effects of tap water and distilled/RO on germination rate. This is because the seeds that I have are so precious to me. So don't want to waste them. This information is second hand from others growers.

So far for my seeds I've been using RO water that I buy from a water dispenser unit near my house. Occasionally, I forgot to buy. So I use tap water. Link to Post - Back to Top LoggedMy Wantlistisaacgoh

Do u mean plant hormone to be rooting hormone? Link to Post - Back to Top Logged[Naj Grow List] --- [Naj Wanted List]cactustts

Hey Issac, you fertilised your planted tank, don't you? I don't think it is suitable to use fish tank water as it contained minerals that harmful to CPs. Link to Post - Back to Top LoggedTSDavid

Yes, vitamin B1 I think. but this is the liquid form. This is also good to reduce plant stress when I repot them. It is not fertiliser and will nto burn the roots. Link to Post - Back to Top LoggedMy Wantlistisaacgoh

Minimal fertilisation nowadays(because keeping shrimps) so I guess they'll be ok.

Hmm, but still I don't know if the amonia and shrimp waste would affect them. Sundews are very sensitive to minirals and salts in their water. Link to Post - Back to Top LoggedMy Wantlistcactustts

« Reply #15 on 10 Feb, 2007, 18:22 »I use only lousy s. moss. Soak chopped sphagnum moss, put in a 'tao hue' container(with hole). Just sprinkle the seeds on top of the moss. Place them outdoor under direct sun light, 4-6hour per day. Water them using water tray method(RO water).

Can u see them?

[shawnintland]

I decided to run a little 'test' on some D. intermedia 'Cuba' seeds. One box is on pure chopped sphagnum over a layer of perlite, next is pure peat over layer of perlite and last is peat and sand 50/50 over layer of perlite. They were all planted on Sept. 19th and today is Oct. 13th so it's been 24 days so far. There has been excellent germination on the sphagnum and only one each on the two boxes on peat/peat-sand. Guess I know which way to do them in the future! I believe that the others will follow soon because I planted the last batches of D. intermedia 'Great Swamp' on pure peat and also on peat sand mix and both germinated quite well but without a pure sphagnum to compare them with. Below are some photos;

On pure sphagnum;






On peat;


On peat/sand mix;


D. intermedia 'Great Swamp';




And just for fun, D. tokaensis;

Shawn, Looks like you better find that 10x fixed magnifier prior to transplanting else you definately will come to Penang with 2 inches thick spectacles.

[jessilim]

Oh, the info abaove will definately help... but most of you do it in a controlled environment (terrarium) or manage to arrange a controlled amount of sunlight... I won't be able to do that as I don't have a terrarium and I'm in the office almost all the time there is sunlight outside...

Is it going to work at all?

[plantlover]

I germinate my burmanii and intermedia seeds like this:
1. Sprinkle the seeds on very damp LFS
2. Mist them with pure water
3. Put the pot in a sunny place
4. Fill up the water tray when the water drys up
5. Leave it alone

4-6 weeks later the seeds will germinate. The humidity of my place is very high at night with dew and moisture everywhere. But during the afternoon it can be hot.

[jessilim]

Hi Aaron, soli ah... what's LFS?

Has anyone ever tried just putting them on wet cotton. Sorry, the thought just came to mind. That way you can see the balck specks. It works for taugeh right? Maybe need to put some of that plant hormone that David was talking about since there's no soil / nutrition on the cotton.

I think my place is more dry. Rather windy at times. Outside can be dewy too sometimes. Hmmm.. mix I suppose.

[plantlover]

LFS is Long Fibered Spagnum Moss. They are those long strands of sphagnum moss without being chopped. Most sphagnum moss sold are in that form. I've never tried cotton. Don't need plant hormone. My plants all germinate without the help of plant hormone.

[jessilim]

You don't chop up your Sphagnum moss?

[plantlover]

No. I only used chopped sphagnum for germinating nepenthes and darlingtonia seeds. I use normal sphagnum for all my plants and to germinate drosera seeds.

[bactrus]

Jessi,

Chop up the sphagnum moss otherwise seeds will fall in between the gaps of moss. Shawnintland posted something like that yesterday. Follow his sphagnum moss tray method forget about the rest.

Forgot to mention. Keep away from rain!! Water from bottom only, i.e. don't pour water from the top like we normally do with plants, else seeds gets wash down or concentrated at the sides
