Here are yesterday's dragon fruit cuttings being prepped for planting.

I snipped the bottoms and am letting them dry up. They dry pretty quickly (as you can see in pic 2, it's already dried quite a bit), but I'm going to give it another day or two before planting.

I call it "dragon fruit alley", located near punalu'u beach on the south side of the island.

These are growing wild on both sides of the road.

I didn't see any fruit, but I did see some buds.

Dragon fruit definitely like this sunny, hot environment. They would definitely be happy with more rain, but they rot in areas with a whole lot of rain.

Pic 3: one of the buds I saw
Pic 4: the cuttings I took. I tried to pick fat, healthy cuttings. Dragon fruit plants are pretty slow-growing so I picked some fairly robust pieces.

Pro-tip for handling dragon fruit plants: the spikes ARE sharp, so wear gloves and be careful.

Au collège, par exemple, lorsque l'on interroge des élèves sur le temps passé sur les régies publicitaires, le constat est vraiment inquiétant ‼️

Le temps passé chaque jour, la manière dont iels se décrivent et qui fait penser à des "camé•es", les fakesnews qu'iels partagent et pire que tout, qui les manipules...

En tant qu'enseignant, cela fait plusieurs années que j'affirme que sur les algorithmes et non sur les écrans, il y a un enjeu de santé publique à prendre la mesure de la catastrophe en cours !

S'y ajoute l'impossibilité, via des outils numériques privateurs des #BATMMAAN (voir en bas du pouet pour la signification de BATMMAAN) de proposer de la pensée complexe, nuancée, argumentée et surtout, sortie des mécaniques algorithmiques attentionnelles.

Partout, il faut des formats courts, hyper engageants, simples, voire simplistes...

C'est l'installation d'une pensée fascisante pour les masses au prétexte de la rapidité et de la simplicité. Et les comptes importants s'en fichent, car souvent iels peuvent exprimer leur pensée de façon développée dans les médias. (politiques, personnalités médiatiques, ... )

Et avec #X , #Instagram , #facebook , #tiktok , #youtube ces pratiques ont contaminé l'espace social et donc politique... ( #propagation de Dominique Boulier)

Nous avons un travail considérable devant nous pour permettre aux gens de sortir d'une addiction collective... C'est un peu comme tenter de baisser la quantité de sucre dans les aliments transformés !

Le mieux, c'est de cuisiner soi-même avec des produits locaux, bio et de saisons donc 😉 ✊

@Lezecolos

Le problème majeur est que les #GAFAM et les #merdias possédés par des milliardaires s'entraident et se renforcent mutuellement !

Mais oui, #X/twitter est un problème au même titre que #facebook , #instagram ou #tiktok

Nier cela, ce serait tout autant une erreur que de nier le problème de #quipossedelesmedias ‼️

Les travaux sur la nocivité des algorithmes doivent être pris en compte dans l'analyse critique des médias comme dans celle sur la #propagation .

#DominiqueBoulier le démontre dans son livre éponyme !

I pulled a bunch of #vanilla orchid off an 'ohi'a tree that it was climbing.

My plan is to propagate. Vanilla can grow from a cutting that includes just 1 node (which can grow leaf, root, and new stem), but more nodes per cutting improves chance of success. I haven't decided yet how many cuttings to make.

Pic 1 shows the entire harvest (it's in several pieces because I had to cut it to separate it from the 'ohi'a. Part of its growing strategy is wrapping tightly up & down the trunk of the host tree. 'ohi'a has flaky bark and the vanilla gets under there & holds tight. Getting under the bark protects the air roots from direct sun and drying out too much.)

Pic 2 shows new stem parts coming out of a bunch of nodes along the main stem. This was right above the spot where I'd previously cut it.

Pic 3 shows a closeup on the new growth. So cool!

The peace lily saga continues:

Not only did the peace lily produce seeds: the seeds germinated, and now I have a number of ever so small peace lily seedlings.

On March 2nd I sowed some seeds on a wet paper towel in a petri dish that sat in the windowsill.

On March 29th some of the seeds seemed to have germinated (see first photo — can you spot the tiny roots?) and the germinated seeds were transferred to small pots that were kept in a “greenhouse” made from a plastic bag to avoid dehydration.

The second photo was taken today (April 20th) and shows a couple of seedlings that have developed their first leaf. Match for scale.

This is a project that has called for patience:

The period from pollination to seeds took 4-5 months. Then it took roughly 1 month for the seeds to germinate, and 3 weeks later the seedlings have just a tiny leaf each. Things can still go wrong, but I'm pretty confident that I will end up having several mature peace lilly plants grown from seeds.

Meanwhile, I have cross-pollinated two peace lily plants. One was the plant I've had for 10+ years. The other was a “miniature” plant I bought last summer, that was meant to sit on the very narrow windowsill in my bathroom. I was naive enough to hope that some gardener had developed a miniature cultivar of the peace lily, but I was fooled: the plant was just a baby plant of something that has now grown into a mature peace lily plant. Latipac be damned!

Now I hope that the two plants are unrelated, and not just perpetuated clones, so that the cross-pollination introduces some genetic variability. Perhaps I am wiser at the end of 2024.

I wish y'all a peace(lily)ful weekend.

🕊️ Peace now! 🇵🇸 السلام الآن 🇮🇱 שלום עכשיו

I have a confession: Months ago I tried to persuade y'all that no Danish nocturnal insects takes interest in the flowers of Hoya linearis.

I lied.

The plant has been hanging from the ceiling in my bedroom all winter. Today I took it down to offer it some water, and now there are downy seeds all over my bedroom (I guess I should be grateful that I'm single).

To conclude:

Some of the flowers must have been pollinated while the plant was hanging in the garden last summer.

The seedpods must have looked somewhat like the leaves of the plant, and in retrospect I have been a little worried since some of the “leaves” looked yellowish, but since it was just here and there and didn't seem to affect the whole plant, I wasn't too worried.

Turns out the yellow “leaves” were actually seedpods that have now burts open and revealed lots and lots of seeds — each attached to something that looks like eiderdown. They fly at even the faintest breeze. This is gonna be fun…

People who know me also know that now I have to try and sow those seeds to see if I can grow new plants from seeds.

Did my mom and dad fsck in a greenhouse, that early summerday back then? 🤔

Hello @houseplants and @plants 👋

Are you ready, guys? Now this adventure is getting really exciting:

More than three months ago I hand-pollinated some still closed spadices of peace lily (Spathiphyllum) — see parent post.

For a couple of weeks, one of the swollen spadices had become increasingly brown, and today I was sure there was no longer any connection to the stem or the mother plant, so I cut it off and broke it up on a lunch plate. (The three remaining spadices are still green.)

We have seeds!! 🤸

There may still be a long way to germination and plants, but undeniably having actual seeds feels like a huge progress. The pollination code has finally been broken!

Yay! 😸

Preliminary results:

In the past six months I have attempted to pollinate each flower on my Spathiphyllum, with nothing to show for it: while the spadix does grow initially, the spathe will eventually wither and there are no seeds to be found inside the spadix (see the first photo).

So what if I pollinate the spadix before the spadix has opened? This looks much more promising: the spadix grows much larger (see the second photo).

I have pollinated lots of open inflorescences with no results other than some initial growth, but no seeds.

I have pollinated three closed spadices, and all three have grown to a volume that is currently at least twice the volume of any open-pollinated spadix.

The proof is in the pudding, they say, so it's a bit early to conclude anything, but so far it looks like a promising pattern.

Am I really the only person on the entire fediverse who has attempted seed propagation of their peace lily?
