Hoya danumensis Hoya cystiantha and Hoya praetorii in vials

I'd love to order danumensis and cystiantha ( the travel can take 3 weeks to my South American country) do you think that they would arrive alive? What about the vials?

I will answer you after our experiment is done : on the morning of the 18 January we have filled vials with water in gel. The two cuttings of Hoya danumensis et Hoya cystanthia are put in a box, the same day we add a cutting of Hoya praetorii. The cuttings are not rooted.
14 days have passed when
on 31 January ( evening ) we open the box that was staying at room temperature ( 22 - 30 Celsius ); the result is shown below : only Hoya cystanthia lost leaves ( two leaves ).

The leaves of the three Hoya are slightly dehydrated although our environment is humid.

These species are difficult to ship, Hoya praetorii being the most fragile of the three plants.

Some importers would say that wrapping the plants in a plastic bag would have been of benefit : the cuttings would have been less dehydrated. Others would deny it, possibly arguing that shipping plants bare roots with paper only is less risky. Only large scale experiments
on these hard to ship species in various situations regarding humidity and temperature could tell which method is best.

On day 14 we are re putting the Hoya cuttings in their box having made no change in the packing : we will see their state at the end of the third week.

---------- On day 20 of the experiment Hoya pratetorii is still green, ( picture to the right ) apparently in good health and with all its leaves but the two others have dried out, leaves still on the stems. It seems that the vial is a good device for praetorii, as compared to other methods such as bare cutting.

---------- On day 31 ( 19 February ) Hoya praetorii is still good for replanting, perfectly green a small root has come in the gel.

These 3 species are among the most fragile Hoya in travel. Most Hoya species can travel 3 weeks in boxes with very good survival rates without vials.

---------- On day 60 ( 18 March ) Hoya praetorii is still alive, we take it out of the box and attach it to a piece of coconut shell on a rubber tree.

It seems perfect, I think I'm going to try even without experience is completed!

Hi Pascal and Suree,

Honestly.... I didn't like the 14th day result! I believe that more 14 days will be the death of the plants.

What do you think? What about rooted plants? Would them be more sucessfull???

Thank you very much for showing the results!

The ones I brought from Los Angeles arrived in Brazil just like those in your picture and didn't survive, and I brought them with me in the plain in my luggage

Hi Mitzi,

We think that H. praetorii is so slow to root that it would rot before we could see the first root coming in the gel. Now if we take a rooted one and insert the base in a vial we have a method that does not differ a lot from packing the base in a plastic bag containing bits of gel. ( our by default method for rooted plants )

Hello Pascal & Suree.
Thanks for help in delicate ship hoya.

Mitzi said...

I wonder if rooted will arrive alive. But the only way to know is trying!

Hello Pascal e Surre!!
you looked at the cuts and Hoya Hoya danumensis cystiantha??
Often the cuts dry leaves but the industry remains alive. After hydrating we still green.

Hi Pascal, I forgot to ask, is the stem green? Is there any sap, energy in the stem? I've received many hoyas looking dead but it was alive.

Just curious...........

Aleyagarden said...

Thank you for your comments ! yes did cut the stems of the 2 looking dead ones, their inside was dry.
After 31 days the survival of Hoya praetorii in vial with gel is very surprising as it is known to be with a few others including danumensis and cystiantha one of the hardest Hoya to ship !!! Thanks Mitzi for having made public your positive experience with vials from your trip to the USA !

Mitzi said...

This is a great news Pascal!!!! After 60 days the hoya still alive...... it is very impressive!!!!

Great news for danumensis and cytanthia too as after 14 days they could still be replanted if we had not gone further with the experiment. ( I removed one of your comments, the same entered twice )

Mitzi said...

It is a good news although I don't think I can get the cuts in 14 days, as you probably know.

Maybe if sent by EMS, but the customs risk is high!
