sowing orchid seeds on trees

just posted in junglegroves facebook group...

***********************

what are the chances that a residential tree in central florida harbors the fungus that orchid seeds need to germinate? because this fungus is microscopic, you can't see it with the naked eye. but if an orchid seed actually germinated on the bark, that would effectively prove the fungus is present.

“the proof is in the pudding” is how i learned, back in 2011, that this fungus was living on my tree in los angeles, california. i sowed orchid seeds on my tree and quite a few germinated. every single one did so within ½” of the roots of orchids already established on the tree.


so the fungus is definitely present! however, under those hot and dry conditions, the fungus couldn't venture very far from its home in the moist orchid roots. in theory, it's a very different story in humid and rainy central florida.

here’s my latest method for sowing orchid seeds on trees:

  1. thicken the water: take a 300ml bottle of water and pour out a bit. add about 1/4 teaspoon of xanthan gum powder, strongly shake for one minute, and let it sit for 15 minutes until it turns into a smooth gel.
  2. wet the tree bark: while waiting for the water to thicken, spray your trees thoroughly with a hose, because dry bark will cause the seed gel to slide right off.
  3. mix in the seeds: add your orchid seeds to the bottle and shake thoroughly so they are evenly distributed.
  4. use a smaller tube: pour the seed mixture into a small coin tube or a similar container. draw the seed gel from this tube with a 3ml pipette while you work—that way, if you accidentally drop it, you only lose 10,000 seeds instead of a million.
  5. sow the seeds: use the pipette to place the seed gel directly on or near existing orchid roots. if your trees don't have orchids yet, target damp patches of moss, ferns, or lichen where the necessary fungus is most likely to be.

i recently tried using this xanthan gum technique for the first time. there’s an ideal ratio of xanthan powder to water, but i have no idea what it is. the ratio that i used did make applying the seeds to trees significantly easier than using plain water. as for its impact on the fungus, ai suggests it should have a positive effect and help encourage seed germination.

if you live in central florida and want to join a fun, family-friendly science experiment to see how widespread this beneficial fungus really is, i’d love to mail you a starter kit!

for just the cost of shipping ($7), you’ll get:


  • roughly 1 million orchid seeds
  • a packet of xanthan gum powder
  • a 3ml pipette

if no seeds germinate, it gives us some evidence that the fungus isn’t present. but if they do germinate, it proves the fungus is there—and you’ll get the joy of watching those orchid seedlings grow and bloom right on your trees!

is it possible that the syngonium roots on an ornamental pear tree harbor the fungus that orchid seeds need to germinate?

how i grow fancy ficus from cuttings

ficus trade secret #1

when growing a plant from cuttings, normally you cut back leaves enough to reduce their water loss but not too much since the leaves supply the stem with the energy it needs to root.   here's 1 cutting of ficus auriculata and 4 cuttings of ficus timlada...                                           



but instead of cutting back the leaves, i simply place them in 2 gallon zip lock bags...


i then place the bags indoors in front of big bright windows... 


i've successfully used this technique with ficus dammaropsis...

which wasp pollinated ficus everest in vista california?

natural pollination of ficus palmeri and socotrana in california




side by side comparison of ficus socotrana and ficus everest 


mike fons messaged me that a fig on his everest was ripe and had seeds.  he sent me a couple figs... 



i extracted the seeds... 



the everest seeds started to germinate a week later...



nice!

rare fig auction

auctioning numerous rare figs.  descriptions followed by photos...


my hybrids (small seedlings)


ficus fraseri x carica - mother is an australian sandpaper fig (sycidium subgenus).  small tree with small figs.  haven’t tested its graft compatible with carica.  the hybrid seedlings have been relatively vigorous.  the one seedling i grafted onto carica seems very compatible.  so far most of the seedlings have leaves more lobed than carica.

ficus opposita x carica - mother is another australian sandpaper species with small figs on a small tree.  my figs are sweet, with green flesh and a flavor a bit like kiwi.  opposita is only a little graft compatible with carica, but the hybrid seedlings seem relatively vigorous.  most of the seedlings have spade shaped leaves.  so far i’ve only grafted one seedling onto 2 different caricas and both scions seem very compatible.  

ficus racemosa x carica - the mother is a large, cauliflorous tree in the sycomorus sugenus.  the figs are medium size and taste like tropical applesauce.  most if not all of the hybrid seedlings have suffered from some degree of outbreeding depression.  so i’m guessing that carica is more closely related to subgenus sycidium than subgenus sycomorus.  interestingly, racemosa seems to be somewhat more graft compatible with carica than opposita.  this is the first time that a dioecious species (carica) has been crossed with a monoecious species.  

ficus ulmifolia x carica - another sandpaper small tree but this one is from the phillipines.  the figs are small, sweet, and have orange flesh that tastes a bit like melon.  so far the hybrid seedlings seem around as vigorous as the other 2 sycidium hybrids.  haven't yet tried grafting any of the seedlings or the mother onto carica.  


male figs


ficus carica variegated 10 fwy (7” cutting) - found it on the side of the 10 fwy near downtown los angeles.   a large tree had several branches with varying degrees of variegation.  figs are medium size, can be slightly variegated and produce a decent amount of pollen.  not sure about  how many crops it has or the differences between them since i haven’t grown it that long.  no idea if its parthenocarpic.  

ficus coronata (rooted cutting) - small to medium australian sandpaper tree with small figs.  im relatively certain that mine is parthenocarpic since its figs mature and develop anthers.  haven’t tested its graft compatibility with carica.  

ficus ischnopoda (rooted cutting) - small scrambler from india to malaysia that grows near streams (rheophyte) in lightly shaded areas.  small male figs drop before forming anthers so i’m certain its not parthenocarpic.  same subgenus as carica (ficus).  haven’t tested its graft compatibility with carica but i’m certain its compatible, since it looks very similar to my ficus formosana which is compatible with carica.  

ficus johannis hybrid (7” cutting) - purchased this from a reputable source as ficus silverlyre, which is female.  when mine turned out to be male i was initially disappointed so i started calling it silverliar.  however, now i’m happy its male since its small figs have been my most consistent source of pollen.  relatively slow grower on its own roots, not easy to root from cuttings, so i’d highly suggest grafting onto a big carica rootstock.  

ficus palmata hybrid 10 fwy (rooted cutting) - another male fig i discovered on the side of the 10 fwy near downtown los angeles.  no idea if its truly a palmata hybrid but so far its the only wild fig i’ve found with consistently spade shape leaves.  the only other possibility is ficus carica subsp. rupestris which i’d love to get my hands on.  since i’ve only started to grow this wild male tree recently i can’t say much about it, other than the figs are medium size and at least one crop has produced a decent amount of pollen.  no idea if its parthenocarpic.  


species (small seedlings)


ficus austrocaledonica - this is the only ficus i have in the subgenus pharmacosycea, which only contains monoecious species.  this species is a small tree from new caledonia and southern vanuatu that prefers some shade and produces cherry size fruit that are sweet, in theory.  according to google search ai, this species is even more distantly related to carica than urostigma is, so its unlikely to be graft compatible with carica.   

ficus exasperata - sandpaper species from india and africa that forms a medium to large tree that can be loaded with small to medium fruits.  guessing it prefers consistent moisture.  last august i grafted a tiny scion onto a carica in a 15 gallon.  the scion took but so far it hasn’t grown much.  then again its competing with a strongly growing scion of ficus fraseri x carica.

ficus gasparriniana - small shrubby ficus with neat leaves from india to vietnam.  prefers some shade and regular moisture.  in the same subgenus as carica, so no surprise they are quite graft compatible.  this is the only ficus i have that ripens and forms viable seeds without the help of a pollinator.  when the small fruits are fully ripe they are sweet and a bit like banana (very generous description) but the seeds are so large and numerous that they distract from the experience.  

ficus opposita - see hybrid description

ficus racemosa - see hybrid description

ficus septica - small to medium tree from taiwan to australia in the subgenus sycomorus.  its smallish figs are sweet, at least according to youtube videos that i’ve seen.  has been used as a rootstock for carica but in my very limited experience so far they are barely compatible.  

ficus ulmifolia - see hybrid description


species (small rooted cuttings)


ficus auriculata - ornamental and edible dioecious species in the subgenus sycomorus.  small to medium size tree with large leaves.  produces large figs on leafless branches on its trunk.  ranges from india to malaysia.  figs taste pretty good, kinda like strawberry, but there’s quite a bit of variation in fruit quality.  at least one variety is parthenocarpic.  not graft compatible with carica.  in theory these two species were crossed by researchers in israeli more than a decade ago.  i say in theory because i haven’t seen any pics.  

ficus cocculifolia - large tree with large cauliflorous figs from madagascar.  in the subgenus sycomorus and seems quite graft compatible with carica.  the trick is that since carica is deciduous, when cocculifolia is the rootstock it might be necessary to leave it with a branch or two to supply it roots with energy during the winter.  this species was lumped under ficus sycomorus, which is not graft compatible with carica, so i prefer to keep them separate.  

ficus fraseri - see hybrid description 


misc


ficus carica fignomenal seedling (7” cutting) - the two seedlings i have from my fignomenal both seem to be dwarf, so this trait can be inherited.  neither seedling has fruited yet and i’ve been meaning to graft them onto a larger rootstock.  

ficus pumila x carica (small rooted cutting) - not sure if my cross is from one of condit’s originals or from a remake by his colleague william b. storey.  form is somewhat intermediate between both parents, and it grows relatively well, but it is very reluctant to produce figs.  



all the rooted plants that the winner will receive.  male ficus palmata hybrid is in upper left.  plants in 1 gallon pots will be shipped bareroot unless winner prefers otherwise.

mike fons super spider fig

 


my friend mike fons (figfair.com) shared this pic with me of a fig he grew from a seed that came from a dried fig from yunnan china.  pretty sure that the dried fig was a ficus carica that was naturally pollinated by a wasp that emerged from a ficus johannis.
