I just got these Mountain Coconuts to plant, but they seem a bit too green. Would they be able to germinate? I read it is pretty hard to germinate those anyway. Should I remove the mesocarp (the green husk)?
I was planning on letting them dry for a few weeks, then a few weeks in the fridge, then soak them for a few days, then plant them halfway burried in topsoil/peat moss mix and leave them outside to experience daily temperature variation.
Does enyone have experience germinating Parajubaea Torallyi?
I looked and then looked some more and was unable to find any definitive resource on when it is best to start fertilizing seedling palms. Some people claim that seed nutrients are exhausted approximately 2 months after germination, but this may be species dependent or just plain wrong altogether.
I think a little background is warranted.
I started fertilizing some of my seedlings about 3-4 weeks ago, many of them single leafers, roughly between 3-4 months old. I generally use 180-day Nutricote on all my palms. Most of my seedlings are in 2.5" Anderson pots and are doing well. Or so I thought. As of last week, I lost about 10 seedlings, none of which were recent transplants or in any kind of obvious stress. Among the lost species, there were Areca macrocalyx, Pinanga caesia, Dypsis leptocheilos, and a single Cryosophila stauracantha. All were recently fertilized. At the same time, many other species are seemingly unaffected (e.g. Ptychosperma spp, Areca vestiaria, Calyptrocalyx spp.), as well as some of the aforementioned. At least so far.
To be fair, I may have overfertilized and some just couldn't handle it. So I did what any sane palm freak would do and started meticulously removing some of the fertilizer balls from my plants over the weekend. Great project, by the way.
Anyway, enough history. So what do you guys think? When should one start to fertilize? And how much? Are some species really more sensitive than others?
So last year I got some Franken Brahea seeds (among other seeds) courtesy of Dooms Dave. In March 2018 I used the baggie germination method and the Chamaedorea radicalis came right up. The others didn’t, not surprising, some things take longer to germinate.
In May/June of 2018 we moved into a different house and I took the bags and bottom-heating pad and got them set up in the basement of the new place. Well, life takes hold of you and we’re living out of boxes for weeks while getting things set up while still trying to work, take care of kids etc. and my bags full of palm seeds did not get adequate attention. Even within the bags, the soil dried out and I didn’t notice until they were all bone dry....bone dry. I’ve ruined seeds before by letting them dry up so I knew I had blown it. I’m too busy to mess with it so I left them and turned off the bottom heat.
Imagine my surprise when in July 2018 (that’s 16 months after placing them in the bag and probably nearly a year after they dried up) I see palm sprouts galore inside the bag, one even pierced the bag, the rest were bent over at the top of the sealed bag!
I can’t believe it, I’m lucky I noticed them, they could have died from lack of light, let alone water. They are all now safely potted up. Needless to say, after the miracle I quickly went and re-hydrated the remaining bags of seeds, who knows. Might get lucky again.
Does anyone germinate seeds in a germination box (like a little box with a heat light inside)? If you do, does it work well with palms? I might make a little one and try it.
So I have been reading things about people soaking palm seeds in small amounts of bleach and water for a minute or two to prevent them from getting mold while germinating. My question is, when you soak them in the bleach and water solution, do you rinse them with water right after, or do you put them straight into the medium? I have looked for the answer to this and could not find it.
