A recent cactus fiend
I want to start off by saying I really enjoy following your blog. I am also a recent succulent fiend, and truly enjoy checking your posts regularly to get inspired with my collection and learn. One of my beloved Euphorbias has taken a dive and died off slowly. If the photo uploads correctly, I have what I believe is a Euphorbia pulvinata. This is a sad picture I know… This guy was doing fantastic for the few months that I’ve had him. I bought him from a vendor at the Philadelphia Flower Show in March and he was about 2 - 3 inches smaller then, compared to the size you see in this photo. I also repotted him into the pot you see here. His original pot was more of a snug fit with less room along his sides. He was my best grower this spring and always had fresh green ends extending off of his fronds. All 59 of my plants are well documented on a spreadsheet with details listed about each species, as well as my water and fertilization dates. I am organized with the collection and don’t usually miss a watering, or double water things because of this. Besides a small batch thats watered every 7 days or so, I would say that my succulents are watered every 2 weeks in their growing seasons of the spring/summer. Out of nowhere, he developed brown spots and that turned into looking sick and losing limbs to the browning. Limbs began to turn mushy and a light tan color before completely dying. I’m using CactusPlus fertilizer small doses of it once per month give or take while he was clearly growing.
Is this straight up rot from overwatering?
I have more pictures of one of the limbs being dissected before it was totally consumed by the browning. The inside cell structure of a few limbs seemed to have an orangish cluster of tissue that looks like a potential mold. But I’m not 100% convinced it’s mold or a pest problem. None of my other succulents have reacted like this whatsoever. I’d be happy to show you but can’t attach more than one photo here.
What are your thoughts on this?
Dave————- First of all (and despite my often sparse text) I love the amount of detail on this “ask” and I envy your record keeping! Based on everything you’ve shared, it may very well be rot from overwatering. This may sound like a silly question based upon your meticulousness, do you water based on time or do you also check that each plant has thoroughly dried out between waterings? That would be my best guess.
Hello! I was hoping you could help me figure out what is wrong with my plant (which I believe to be an African milk tree)! I bought it ~1 week ago and it had the brown areas on the tips when I bought it, but all the plants of the same type there had similar spots. I thought maybe due to age? But as reading through things online some suggested the rings appearing in the spots may mean a virus? I am unfamiliar with plant diseases such as this and wondering if you maybe knew something more.————- Any chance it was exposed to freezing temperatures? That would be my first guess as the growing tips are often most sensitive. Anyone else have an idea?
Some new cacti and succulent cuttings I’ve gotten
Sorry I’m just getting to this request. The first one is an Opuntia species and the second is a Schlumbergera. There are so many of both that it would be difficult to know exactly which either is without someone more expert than myself. The third one is …. not my area of expertise. Anyone know?The middle shot on the last row is Aloe - again, not sure which species. Anyone?
Here is a closer look for IDing. This cactus is over two decades old. Granted, it is living in a highly restricted environment, but the only suggestion this far is Pachycereus marginatus, which doesn’t seem correct based on the morphology seen here. What other columnar cactus are found in central Mexico?
Si no se ve bien te tomo otra. Lo que te puedo decir de ese cactus es que es muy pequeño del tamaño de mi mano y que tiene más años que yo.
The tropical greenhouse at Plants & Planters features a large selection of cacti and succulents, as well as some very nice tropical plants. The quality of the cacti varied greatly, and, overall, they were a little overpriced. Nevertheless, there were some very nice ones.
djnionas: A close second.
Here is the second half of shots from my visit to Orand Nursery in Fort Worth. The first set focused on their agave selection, so here I have shots mostly showing their cacti, aloes, yucca, and other desert plants. Enjoy!
djnionas: This would have to be my selection for the best of DFW.
Do you know what this is? It was a gift. I’ve rooted 8 cuttings from it so far.Well, it is definitely an Opuntia species, but it is hard to say which one exactly. How much light is it getting and what direction is the exposure? There are a few species that tend to elongate like this, but it could be lack of light. Sorry I can’t be more helpful on exact species. Anyone else?
See the gray bit around the spines toward the bottom? Thats whats concerning. The roots seem healthy but the gray wraps all the way around the base. It hasn’t grown all season and even seems like it even could have shrunk a little. I googled for info, but couldn’t find any images of the base or anyone else with a similar thing going on.————————- aloevulpes: It does look as though it may be rotting - often the roots still look heathy even though the plant is not. But, before you do something drastic (see below), try this. Push on the grayish area. Is it soft and squishy? If so, it is rot. If not, and it is still firm and not spreading, it may be ok. It is perfectly natural for some cacti to get a little woody around the base as they age. Ok, now the drastic part. If it is soft or if it is growing (which I fear it probably is), you are going to have to cut it off as high as needed to only see healthy green plant on the outside and the inside. Do so with a clean knife spritzed with a mild peroxide or bleach solution. Then, set it in a partially sunny, dry area to callous over after spraying it with a peroxide or mild bleach solution. Then, place in soil - watering once - until new roots develop.
A new submission from physiquepictorial:
I bought this one at the begining of the summer. I don’t know if it’s dying because it started out like as a big dome shaped now it shrunk and its starting to get thinner.
The one on the left before and then after:
Well, there is good news and bad news here. The good news is that there is no sign of disease or rot or any other reason why it would die. So, it isn’t going to go anywhere anytime soon. The bad news, though, is that the new growth is pretty measely and thin - a tell-tale sign of not enough light. This is known as etoliated growth or etoliation. Your plant needs placement in an east- or south-facing window and that should set it on a better growth pattern, but the signs of this abnormal growth will never go away.
do you have one cactus that is the most evil in your collection? I have one I dread re-potting because it has millions of tiny hair-like spines that get in your hands even if I wear leather gloves and make me itch for days. (I don't know the IDs of any of my cacti sorry). what is your most evil cactus?
Asked by flupmakintosh
Yours is an Opuntia, or prickly pear - and, undoubtedly, they can be pretty evil.
This one is Opuntia microdasys montrose, or Crazy bunny cactus, and the glochids seem to jump off when you walk by:
Although, after a few run-ins with prickly pears (including a zealous harvesting and eating session of tunas, the fruit that is just as spiny, in Leon, Guanajuato), I am quite careful touching them, either grabbing between glochids or using heavy-duty rubber gloves.
That is why the nastiest cacti I have, are those with the most obvious spines or spikes.
Take this Yucca recurvifolia, for example:
It always pokes me - when I’m watering, when I’m weeding, when I’m moving pots. You would think it would be easy to avoid, so perhaps the problem is that it continues to grow closer and closer to the flagstone (and me).
Next, we have the Argentine toothpick, Stetsonia coryne. This one is deceptive because the spines change color as you follow them away from the plant. It makes you think you have room to reach/grab, but, alas, you do not:
These last two, though, are the worst - and for much the same reason. The spines are not uniform in color, so you don’t know exactly where they end. This is compounded by a greater evil: they are barbed. Maihueniopsis darwinii, commonly called the Darwin cactus, and Opuntia schottii, or the Dog Cholla, are downright EVIL. If you get within touching distance, it is already too late. I can’t tell you the number of times I have accidentally pricked my hand to quickly pull away with an entire pad attached to my finger or a bloody tear from a barbed spine.
The Dog cholla is a recent purchase, so I haven’t had too many painful encounters, but I just have a feeling once it is in the ground, things will change …
How about my fellow cactophiles … what is your “most evil cactus”?
