Anonymous said: Hi I have a plant every similar to elephant bush/jade but not exactly, and the branches are turning green I don't know what's happening could you please help I'm very worried about it, thank you!

Also the leaves are shriveling up and turning brown very quickly almost without notice
Without seeing the plants, it’s hard to say, but it doesn’t sound very promising. It sounds like the plant could be rotting. If that’s the case, then the best course of action would be to take a sharp, sterile knife to the plant and cut off all the infected tissue. If the roots are completely rotten, then trying to take a rot-free cutting would be best.
Hope that helps!


Hey cactusmandan!

I have some questions about my cacti… Do you know why the spikes are falling off on the first cactus? Am I overwatering? And why is the cactus all shriveled at the bottom?

For the second one, any idea why the edges of the leaves are turning white?

Thanks for your time!


Spines falling off isn’t a very good sign and it could be due to the fact that your plant is a bit etiolated, due to a lack of light. I don’t think you’re overwatering. The shrivelling at the base is probably just the natural process whereby the tissue at the base of the plant collapses over time.

If the leaves which are turning white are mostly at the base, then I guess the leaves are dying off as they’re old. If the leaves are turning white towards the apex, then you might need to water the plant a bit more. Kalanchoes generally need more water than cacti.

Hope that helps!

I like pointy plants. :)

Thelocactus rinconensis, Gymnocalycium spegazinii, Eriosyce taltalensis ssp. paucicostata, Hoodia parviflora and Maihueniopsis glomerata.

Geissorhiza aspera is producing quite a few nice flowers, although all of the flowers so far have had aberrant petals. I’m not sure why, but it doesn’t detract from the beauty of the flower too much.

Mammillaria perezdelarosae ssp. andersoniana has very beautiful spination, matched only by a few other cactus species.

The growing season for cacti is coming to a close, but it’s nice to see this Astrophytum capricorne v. major showing quite a late flower. I really love the red throat on this flower.


Any id on the cactus in front cactusmandan ?

Well it’s an Opuntia species. Perhaps Opuntia littoralis, but I’m really not sure. Opuntia species are difficult to ID without seeing the flowers or knowing where the plant originates from in the wild.

This picture isn’t exceptionally interesting, just a meagre-looking seedling. However, this is what’s left (there are an extra 2 seedlings in there now!) of a batch of Brunsvigia herrei seedlings which got very badly sunburnt earlier in the year. The sunburn killed off all the plants which were alive so I was left with an empty pot. Thinking all hope was lost with them I put the pot in a bucket outside and forgot about them. Then followed lots of rain and this pot must’ve been totally submerged for at least a week. During that time, I’m guessing the cool temperatures (this is a winter-active species) and water must’ve managed to cause any ungerminated seeds in the pot to germinate. From this, I’d say don’t be quick to give up on plants and particularly not on seeds. Seeds in particular, as some can be fussy to germinate by conventional methods.

The seed capsules of plants of the Aizoaceae family (Ice plant/living stone family eg: Lithops) are fascinating. Around 98% of species in the family produce hygrochastic seed capsules. This means that the capsules open up in the presence of water, such as when they are wetted by rain. This happens due to the structure of the seed capsules and the cells which make up them. When wetted, the dead cells forming the capsule expand and change shape, allowing the capsules to open as you can see above. When the capsules are fully open, the seeds can be washed out by further raindrops. The capsules are capable of opening in just a number of minutes, which is an important feature in habitat, as rainstorms may be quite short.

The pictures show a seed capsule of Oscularia (Lampranthus) deltoides opening in response to moisture. If I get time, I’ll try to make a time lapse or video of a capsule opening.

megalanthus said: hey dan long time no talk!my hylocereus finally started growing :) I have a question though,how does one get cacti to bloom? just cacti in general


That’s not an easy question to answer, since the cactus family is so big and spans such a vast geographical range! Generally, I’d say there are a few signals which cacti might need to flower: size, hydration status, temperature and sunlight. Size is usually pretty important, particularly with Opuntia and Hylocereus and some other Epiphytes. Most Hylocereus species have to be huge to flower! Size is important for all cacti, although the flowering size varies a lot. Some Rebutia species might flower when they’re no bigger than an inch in diameter, whereas Echinocactus grusonii usually needs to be at least 1-2 feet in diameter.

A well-watered (but not overwatered) cactus is generally more likely to flower than a thoroughly thirsty cactus. However, it can be the opposite case for Tephrocactus species which usually reproduce asexually. Many of them need to be significantly starved of water before they’ll flower. Flowering expends a lot of water, so cacti need to be sure they can afford to use such a vast amount of water to flower. If a cactus produces a particularly large flush of flowers, then you can usually see them go from looking very plump to substantially sunken or wrinkled. Or in small cacti, they might halve in size when flowering, from the amount of water they use in doing so.

Temperature is whole other matter. Some cacti keep a cold, dry dormancy period over winter to flower. Others will just flower whenever it’s warm enough and they have enough water to flower. Frailea species need really hot, harsh temperatures for their flowers to open, otherwise they often just go from bud to fruit without flowering. Lots of sunlight is important too, preferably full sun.

tl;dr - Sun, water, warmth.

Happy growing!

Lovely red flowers on the aptly named Gymnocalycium carminanthum. This flower managed to open properly without being obstructed by the spines. The spines on this species are great and turn a nice chestnut colour when wet.

Now for a bit of a change from the usual plants I post. This flower is instead from an African bulb plant - Geissorhiza aspera. I actually bought these bulbs as Geissorhiza radians, but it turns out I was sent the wrong plant. I’m not too bothered really, as these are beautiful too! I think this species is from a winter-rainfall region in Africa, although it’s grown fine throughout the summer here. 

My other winter growing bulbs (which are actually dormant now like they’re meant to be!) will probably start waking up next month, dependent on the weather.

I also got this cactus for my birthday and couldn’t ID it could you please help Thank you! c:


Hello again!

That’s the ever popular Mammillaria elongata. I’ve heard mixed things about this species. Some people find them difficult and others find them totally indestructible. I don’t think they’re difficult at all, just don’t drown them. ;)

Could you help me ID this pleaaseee I got it a couple days ago for my birthday but I can’t seem to ID it



I’m not great at IDing plants of the family Crassulaceae, but I think it’s from the genus Pachyphytum. I can’t quite figure out the species, but P. hookeri is a possibility. Perhaps someone else has a better idea than me? :)

An assortment of Ariocarpus seedlings I repotted a few days ago. There are some nicely sized taproots on this lot. I’m not quite sure on the IDs of these yet, since the ink on the labels faded with light exposure, so I’ll have to match them up with the names of my seed list at some point in the future. Some of them are obvious already though, particularly the Ariocarpus kotschoubeyanus forms. Speaking of Ariocarpus, I noticed the first bud on any of my Ariocarpus today, on Ariocarpus agavoides! It’ll be my first Ariocarpus flower, presuming the snails don’t notice it. :)
