My Robinia tree is so big now! It’s a bit lopsided and need a good pruning, but it’s hard to cut off these beautiful branches. I want to keep this one short and compact, kind of like a bonsai.
There’s fluff on the CO x OR seedlings already after 2 weeks, and also tiny transparent spines. It’s nice to see them grow this fast without any casualties. They probably inherited the hardiness of the Astrophytum ornatum.
I think I induced blooming on my 4 year old Euphorbia obesa by fixing its roots a month ago. The feeder roots had completely disappeared, so I dipped the bare tap root in rooting hormone gel. I kept watering, but left it alone without checking if the roots grew back.
I think the plant is doing well. Only a couple of weeks after the treatment, I saw little flower buds appear on the newest growth!
These are my Euphorbia obesas first ever flowers. They’re tiny and not completely developed yet. I’ll make sure to post again when the rest of the buds bloom.
You can tell from the shape of the flowers that this plant is female.
This cactus is sooo slow growing I can’t believe it. I grew this from seeds 3,5 years ago and it’s only 3 cm in diameter. It just grew a spine-looking thing, but it’s easy to miss. The spine is poking out right at the top of the plant. Hopefully this will grow into one of the characteristic curly spines, that made Astrophytum capricorne a popular cactus.
This is a different seedling than the one I showed you last time. I pruned the top and two branches popped out. It seems to be progressing faster than the other seedlings and it’s fatter than most of them, too.
I have to change the soil fairly often because the fertilizer I’ve been giving them, makes algae thrive like crazy. I may need to try a different one.
More Astrophytum coahuilense x ornatum seedlings have germinated. The oldest ones now look like little pink hearts. The grow light bulbs are a tiny bit too strong for cactus seedlings, but the redness here is still within the normal range. At least they aren’t stretching for light, which is arguably worse.
So far I have only seen mold on a couple of seeds and it’s especially visible when I use the macro lens for my phone. I’m keeping an eye on that, because I don’t want it to spread to the healthy seedlings. I’ve managed to keep it down to a minimum by washing the seeds in hydrogen peroxide before I tried to germinate them. I make sure to vent the little greenhouse I keep them in, by taking the lid off for half an hour each day, too.
My experiment was a success! The seeds are viable and the first one germinated today, 5 days after sowing. Pretty much all cactus seedlings look like this when they first germinate, so it’s still way too early to tell if they’re a hybrid of my Astrophytum coahuilense and ornatum. It will probably be at least 4-5 months, maybe even a year before you can properly spot the difference between these hybrids and “purebred” ornatum or coahuilense.
First, let’s just see if they actually survive the tiny seedling stage.
These cacti have grown so fast I can’t believe it. Normally, if you grow cactus from seeds, you’re going to have to wait several years for them to reach this size. These are only 2,5 years old and are somewhere between 11-13 centimeters tall. My hand for scale.
I’m hoping for some flowers soon, so I can properly identify them.
I haven’t checked on the Astrophytum ornatum for a few days, so I only just noticed that its seed pod popped open and the seeds were almost spilling out. I didn’t want to harvest them too early, so I just left the pod on the plant and forgot about it. Now they’re definitely ready to be planted!
The seeds are supposed to be a hybrid of Astrophytum ornatum and Astrophytum coahuilense, but I’m not sure how that works or if this hybrid has a name. Coahuilense x Ornatum maybe? I don’t know, the seedlings may just all end up looking like regular Astroptytum ornatum when they’re older.
I washed the seeds in 3% hydrogen peroxide for a few minutes and planted them all at once. If the seeds are fertile, they should germinate very soon!
4 Pseudolithos seedlings are still alive. I planted some of them together to save space and they didn’t seem to mind being carefully repotted anyway. One of them is a Pseudolithos cubiformis (top right in the first photo) and the rest are P. migiurtinus.
The little bubbles have started to show on top of most of the seedlings. It will be a while before they’re completely covered in frog-like skin, but right now they’re so cute!
