Spring is on its way, they feel it (9 pics)

Finally, after months of darkness, we've had 2 weeks of sun (and temperatures below freezing). It is amazing how only 2 sunny weeks can transform lithops and give other plants a boost. After all the losses this year, seeing lithops actually not affected by the dark environment encourages me to focus more on them in the future. Other mesembs seem to be very touchy and even without water they stretch and die if there is not enough light. Lithops however, just proceed with their regeneration, no problem. They do fine as long as they're not being watered.

The old leaves are getting very soft first.

Then they get lines and wrinkles at the edges.

Then become thin and transparent.

Until they slip around the edges of the new leaves and disappear.

These look like the old leaves are deflating.

I was particularly relieved to see the below plant regenerate. It skipped a year meaning it has not regenerated last year at all. This year it just grows normally.

Bonus pic: Nothing says spring is coming like Sinningia leucotricha waking up :)

Other developments (12 pics)

There are other things I noticed on the windowsill recently.

For example, I was very surprised to find a seed pod on my Argyroderma crateriforme. The plant flowered out of two heads this year: one flower wilted into nothing, the other however has developed a fruit. Not sure what happened there as I haven't pollinated it. I only have this one Argyroderma plant. If there are some viable seeds inside it would be interesting to see what kind of plants will germinate.

Then, there are the Adromischus marianae v. herrei I'm totally fascinated by. That's no news to you. I post about them frequently. But they are so worth a closer look all around the year.

I was under the impression that they grow very slowly. And so it was surprising to see that, actually, some plants have had a huge leap in development. The leaf cuttings that have started growing own leaves in April (left pic) now look almost like adult plants!

The red-ish specimen has grown a lot of new leaves over the year, too. It was barely growing last year but this year there is a big progress. The photo to the left was taken in June.

By the way, notice how red it was last winter? We had good light and I was keeping it dry. This teaches us not to trust all we see on Ebay. Red cultivars are being in high demand and very expensive. Not all would be proper cultivars though. Sometimes it's just sun tan. Once they transfer from a sunny greenhouse to an environment with less sufficient light they very well might turn green on you. 

The mother plant of the leaf cuttings above and its previous cuttings however haven't grown much. I blame the flowering. They spend all their energy on those huge inflorescences they grow all summer. They look impressive and I was happy to watch them grow and the flowers open. Unfortunately while the inflorescence is there the plant does not grow any new leaves at all. I'd like them to rather grow leaves and so, I think, next year I won't let them grow flowers. There is no chance of seeds anyway as all of my plants are clones of one and the same plant and are genetically identical.

And as for the seedlings, they are still alive. But not more than that. Just tiny green blobs sitting on the pumice. No sign of a second leaf yet. It's been 6 months.

Oh, and this is what I was talking about when I said Anacampseros look dead right now. Not all are this dramatic but you can see how depressing it looks.

No news from lithops and conos. Lithops are growing new leaves on the inside. Conophytums are preparing to sleep already.

At least this Titanopsis calcarea seems to be growing flowers. That's something to look forward to (unless it aborts them).

And here's one bonus picture to end on a high note :)

New lithops 2017 - Part 1 (14 pics)

This year I feel like focusing more on lithops again. Needless to say, it means new acquisitions and more sowing later this year. Do I still have room for that? I do. How?! I am just as surprised as you are. Sometimes the windowsill feels like a plant-growing Tardis. The trick is to use small pots and plant as many plants as possible in each of them. If I only have one small plant of a certain species I would never give it a container all for itself. How wasteful is that! It can share it with at least one more plant. And they can be joined by others if necessary. I'm not a nursery and I have good records of what I grow so there's no need to separate everything.

I've bought some lithops and conophytums at the fair in Essen lately. The conophytums are still more or less in sheaths but the new lithops are ready for pictures. I think with the new purchases I have been favoring white-flowering species more than usual. Mainly because they are a challenge for me. Somehow I have difficulties growing them. By buying well-grown specimen the task becomes "keep them in good shape" rather than "get them into a good shape", which should be feasible.

For example, here are some L. karasmontana. I really like the yellow-orange kind and so I ended up with 4 of those. Neat shapes!

Of course I could not walk past beautifully grown L. lesliei and L. aucampiae

Lithops pseudotruncatella ssp. groendrayensis were so fine I got three.

This is just part 1 of the new lithops introductions. I will post more pictures soon :)

Lithops experiment part 7

Hi guys! I heard you are wondering about what happened to the L. pseudotruncatella from the "Lithops experiment". Let me show you in this last installment of the series.

It has been exactly 2 years and 2 leaf changes and yet it is no use. From the three severely overfed and stretched plants I started with only one survived and it looks terrible. Despite all my efforts like keeping it dry for many months, cutting off old leaves, giving it as much light as possible, I ended up with an ugly plant that doesn't look like it'll make it much longer. I believe there is no chance it will ever be flat and short. I will keep it until it dies of course but I don't expect any improvement.

And so, to draw a conclusion, if you ever come across a lithops bunch like this, just leave it in the store. They will die within their first year at your place and if they survive longer they will never return to any kind of healthy look. It might feel like you are rescuing the plants but actually they are already gone. A better investment of your time and effort is to grow them from seed and keep them in good shape from the very start. In the same 2 years you will have cute little plants of nice shape, color and pattern.

PS: The white marks are from mites... This plant really has no luck.

Lithops experiment part 6 (2 pics)

Seeing that my last post about the troubled L. pseudotruncatella was back in December it's time to update you on their progress.

Yes, they are still quite ugly. My hopes of getting them into good shape within one regeneration cycle were too much but hey, no rush. Simple survival goes first. On the survival front I guess they are at 50%. The best looking plant out of three has perished - go figure! Another has lost one head. The balance is two plants, one and two heads.

It's almost May and they've been watered twice so far. They react well to water and, even though they are still way too long, they don't get any longer but bigger and more substantial instead. I intend to be very strict with them so they'll need their strength later. Long way ahead of them.

New year, new life for lithops - part 1 (12 pics)

These past several days it was sunny at last and lithops are known to react to that. They're not wasting time. All of a sudden new shiny faces started popping up here and there. What was taking months to prepare progresses very quickly when spring comes. Some still have lots of resources to recycle, others have regenerated completely and are just sitting there, waiting for their first watering to start growing. Most of the plants below are my good friends since years and it's always a relief to see them go through their annual cycle timely and in a proper manner. The shapes and colors are all I can wish for, too. It really is absolutely possible to grow short and flat plants on a sunny windowsill in Europe, don't get discouraged! The trick is in watering timing, substrate and maybe in the small size of the pots, too. But it IS possible to grow them well year after year without artificial light, and if you like these plants you should try it ;)

C363 L. fulviceps 'Aurea' and C384 L. pseudotruncatella v. dendritica sharing a container. I should probably separate them but they're such good neighbors. 

Aureas are very pretty indeed.

So are their milky relatives C222 L. fulviceps v. lactinea.

This one is a bit shy but will spread its wings once watered.

C006 L. lesliei ssp. lesliei v. minor are from the bunch of my very first seedlings, sown in 2008. New leaves are glistening in the sun. Love them!

These C382 L. bromfieldii v. glaudinae hatched in 2010 and are always a beautiful, natural sight during leaf change.

C362 L. bromfieldii v. insularis 'Sulphurea' are supposed to get new heads every year. Mine doesn't go beyond four.

C392 L. aucampiae 'Storm's Snowcap' are changing nicely but only when they are kept small. In my experience any fat aucampiae (normally one from a hardware store) will choke on its old leaves. 

L. dorotheae have accumulated a lot over the year, as always, even though I barely water them and never fertilize. Nevertheless they regenerate without a problem every year (good metabolism? :D ) so I don't mind.
