Re: Accidental seedlings inspiring experiment

Noticed a couple seeds stuck on the rocks in the unbagged tray. I looked for that after planting and didn't see any, so I think they must have floated up when I poured water on them. Washed them down with the sprayer. Might be hollow seeds - I don't know if viable ones can float - but I'm going to s...

Re: First seed-starting attempt

You don't want them in direct sun in the early stages; either put them in a position the sun doesn't hit directly, or provide shading. Tissue paper works.

Re: Accidental seedlings inspiring experiment

Got to be careful with direct sun on small seedlings, most of them just can't take it. Dappled sunlight maybe, or perhaps a short period each day, but generally bright shade is better for at least the first few months. I'm well aware of that, which is why I don't have them right under the window, b...

Re: Shrivelling ferocactus

The lesson to take from this is: remove all the old potting mix when repotting a plant that's in a bad mix. Don't worry about losing a few roots, it'll grow more. Peat is hard to re-moisten when it's dried out, and water doesn't move readily between media of different consistencies. If you leave a r...

Re: Spider mite or predator?

Seen these critters many times in my garden - the commonest species gets up to .5 mm in size, easily visible to the naked eye (when I was younger, at least). They overwinter as adult females, so as soon as the weather warmed I'd see them running around. Doing some reading about them just now, I lear...

Re: Accidental seedlings inspiring experiment

What sort of light are they getting up there? My loftspace gets hot enough (on sunny days probably way too hot!) but is completely dark. As I mentioned a couple posts back, there's a south-facing window; I've got them back far enough from it they don't get direct sun and get cooked. I'll adjust the...

Re: Accidental seedlings inspiring experiment

Got them planted June 1st - all mixed species for this test, I'll have the fun of figuring out the species later :-k ](*,) . Thought I'd have less chance of getting a whole packet of non-viable seed this way. The medium is what I use for growing adult cacti, with extra gravel added. I use a locally ...

Re: Lophophora and Mammillaria?

For sure none of the ones with big flower buds are Mammillarias. The second one from the left might be, I think, but can't really tell from that picture. Need close-ups.

Re: City Cactus - Please help identify!

I had a smaller-flowered one, couldn't smell anything until I stuck my nose right up close to it. Then I wished I hadn't.

Re: Confused newbie, please help!

Did some more searching and found a site with more details about the different species. They say Gasteria bicolor is quite variable, and one of the examples shown resembles your plant very closely. Very likely that is the correct ID.

Re: Confused newbie, please help!

Definitely a Gasteria, hard to say what species - leaves look a bit wide for bicolor, but I'm not sure either. They tolerate shade, but need better light to bloom, which you gave it. Blooming very nicely.

Re: Hamatocactus bicolor?

Whatever you call it, it's a great cactus. Blooms easily and reliably, easy to grow from seed.

Hamatocactus setispinus is what I've mostly seen them labeled. But, like vlani said, it's just a name.

Re: New purchases part2

At least you spelled it correctly, Dan; "etiolated" is right, just realized I had misspelled it :oops:. I agree that it looks pretty healthy, and it's not misshapen. If you saw no signs of root rot when repotting it, it's fine. Growing them soft is risky, since they rot easily. Commercial ...

Re: New purchases part2

The definition of etoliated is a plant is a lighter color than normal because of growing in low light. Cacti growing in poor light also tend to grow more stretched out, with more space between the spines. Severely etoliated cacti will grow very thin shoots out of the top, completely different from t...

Re: New purchases part2

Hate to contradict, but Mammillaria elongata is a species I'm extremely familiar with. The spines should overlap. there shouldn't be any completely exposed green surface. Look at the photos in the gallery - see what I mean? You can barely see the green. It should be exposed to more sun gradually, I ...
