... from the moment you start to grow & water something in it. From that moment on nutrient content starts to change and competition floats in............

I doubt, that you are right.

The material is not dry, but it is slightly moist.
It has that 'ideal' moisture, which is excellent for growing the tubers all time.

Insofar it is to assume, that the contained microorganisms 'work' since added in production. and they not only benefit the growth of plants, but also the rottting process begins, even if the closed bag is stored in protected cool and dry place. So the 'special beneficial structure' of the material will get lost over a 'certain' time.

Insofar
I think
, the ability of promoting the growth of plants

is limited from about date of production
.
and that date is UNKNOWN.

Hi,

new in the last weeks:
Habenaria schimperiana
Malaxis calophylla

dead:
Geodorum purpureum

Giveaway:
Eulophia andamanensis, brown flowers; the green one flowers better with me. I think that the brown one needs more humidity to flower good, because a friend of mine has more luck with a piece of my plant with regular spraying.

It's the site where I think you found it, the bottom photo is of cv 'Hishou' and the photographer's technique is the same. Kent has moved his site a few times over the past few years, which may explain why you lost it.

I'm glad to report that the error has been resolved. Unfortunately it was rather subtle and I had to redo a large portion of the code, hence the delay.

I was at Kew's Millennium Seed Bank at
Wakehurst
, and read an article about this process, but the seeds are unable to germinate after this.

Thanks for the reply - the plant's foliage is rapidly wilting and going off this week so it will go (forcibly Wink

) into dormancy this weekend!

I think I will have to do the fridge thing - our spring is already starting so trying to keep it cool enough for dormancy will be difficult outside or any other place for that matter.

Thanks for the verdict on the acid-loving /hating. There is so much contradictory information out there on the web, you simply cannot get a straight fact.

WIll keep you updated!

That's right! Smile

The inflorescence is 10-15 cm high which matches the distance between the mother plant and the seedlings. This is very interesting because the dust-seeds of orchids are usually thought of as weightless specks drifting in the slightest breeze and so traveling great distances. I also read somewhere that rainwater flowing on the ground (on steep hillsides where many these plants live) washes the seed away before finally burying them. But here we have evidence that they simply fell straight down and stayed right there, just as bricks do. Surprised

The same Caladenia procera protocorm at 15 weeks old. The last one was taken at 13 weeks. I should point out that there are other seedlings much more advanced than this one, however this one is in a good spot to take photos of to show what's going on. You can see the leaf just starting to emerge from what is essentially the collar structure that you would normally see just below the soil surface.

A couple photos from the last few weeks...

Thank you very much Rogier. I am sure I didn't buy the tuber with that name.
Probably you are correct about all these you mention in your answer.Anyway it is a nice plant and very tall indeed.

I have observed ants rushing around my epipactis gigantea and palustris plants. I don't know if they are after pollen or nectar for food, but whatever they are doing, they have quite successfully pollinated my flowers. Smile

sorry, not really "european" species" Wink

but these are just flowering.

My last two speaking engagements for the year are coming up. I will be at the Martin County Orchid Society on June 22 and the Deerfield Beach Orchid Society on August 10. After that, I will be taking a hiatus from speaking until the beginning of next year. See the embedded Google calendar on this blog page for details about each speaking event:

Florida's Native Orchids

---Prem

We have recently added a number of articles to our blog:

Florida's Native Orchids

Subjects include poetry, the Corkscrew Swamp ghost orchid, the rare and elusive Triphora craigheadii, the common and beautiful Florida Butterfly Orchid, and the Bearded Grass Pink (Calopogon barbatus).

I also have my final speaking engagements coming up. Be sure to check out the embedded Google calendar on my blog page to see the scheduled dates, times and places for these.

Be sure to check out the native orchids website:

Florida's Native and Naturalized Orchids

for updated info/gallery pages on the Grass Pink (Calopogon tuberosus), the Ghost Orchid (Dendrophylax lindenii), the Rose Pogonia (Pogonia ophioglossoides), the Rosebud Orchid (Cleistes bifaria), and Craigshead's Noddingcaps (Triphora craigheadii).

Thank you very much Jed. Those pictures are really helpful Very Happy

I now know what to look out for (Still learning, and I guess I always will be).
Mine lost both leaf and stalk, so I'm presuming what happened was indeed due to multiple factors and is the reason why I was left with such a small mass bulb.

Not giving up though! I'll Just have to be more careful and do more research!

Hello Jed.

I'm not so sure if this is a coccinea. It's definately a type of incarnata (which coccinea is aswell) but the colour is not really typical for coccinea.

I added some pictures of typical coccinea's I made this year

These pictures where made here in The Netherlands so I'm not sure how well these compare to the britisch ones but from the picture's I have seen from british plants the colour is the same

You recognise them instantly, even from a distance.

Here together with a Dact. praetermissa to compare the colours.

It looks like a plant for deep shade - is that the reason why there's so much moss in your pot ?
Good job!

Fred I added the moss layer to control the humidity in the substrate Seramis/Neudohum 80/30. Pot is in deep shade in summer, in winter in the cold greenhouse

Never heard of the "hooded leaf tip" before, thanks for elaborating.

I believe your plant is Ophrys Sphegodes, the early spider orchid. I can't think of or find anything else that it could be. I have never seen this mutation before. It is very unusual.

I only grow a few plants at the minute;

Dactylorhiza Incarnata
Praetermissa var junialis

Epipactis Palustris
Gigantea

Ophrys Apifera

Serapias Lingua

Ponerorchis Graminifolia

I am looking to expand my collection in the autumn to a range of Pleiones, Ophrys Lutea, Ophrys Speculum, Dactylorhiza Fuchsii and Anacamptis Pyramidalis. If anyone has any spares of these plants I will be happy to trade or buy.

Thanks Peter. That is a good idea, so I will try that from now.

I believe you can also put them into the frige while they are still in flasks. Maybe it's easyer that way.
I have experience only with Dactylorhiza, where I found that it is best to deflask them in autumn (if they are big enough). Then the plants can be kept in soil through the winter in an unheated room. They grow perfectly in spring.

I have been told this is a form of Calanthe arcuata from China.
