Taking Euphorbia Cuts


Hello. Our Euphorbia has a top part that has grown quite large and the stalk will not be able to support it much longer. it is already leaning a lot (this photo is a few months old and it has gotten larger).

Is it possible to cut the top part off and plant it? How do these plants do with propagation and how do you suggest we do this. How will the bottom respond/heal from it? Is this a good time of year to do this?

I seem to recall there was a solution you suggested to put on this plant if we cut it as it releases some irritating sap.

Thanks!
Stephanie

 

You can cut below the branching top – leave at least 6 inches of stem below. You should wait until spring, winter is not a great time for this.

First be aware that this is a Euphorbia ammak which has a caustic milky-white latex sap. You need to wear gloves and long sleeves and eye protection when working around this plant. Given its height, this is going to take at least 2 people to safely take cuttings. One to hold the plant, one to do the cutting. If it is taller than it appears you may need a 3rd person to help hold the branch as it is being cut. Please make sure you feel safe with all this before you start. I recommend using a serrated bread knife to cut, and blankets to wrap the branch before cutting.

Basically you need to cut with enough left to be able to plant below the branching. Spray the cut with hydrogen peroxide and set aside to dry for 2 to 3 weeks. Spray the remainder as well, make sure to protect from direct sun until calloused over.

When the branches are fully healed over you can plant them in dry cactus soil and keep dry for a few more weeks. Water only every 3-4 weeks.

Stay safe, Peter

70+ Years From Now


Dear team,
I would like to plant three Dasylirion Wheeleri in my garden. However, could you comment on their lifespan? can they live longer than 70 years?

Thank you,
Matt

Dasylirion are long lived, will grow a trunk and all, but I do not know if they live 70+ years – you can check with a botanic garden to see if they have any that are that old.

We Get Golden Barrel Questions


Hello,

I came across your web site and saw that you answer questions, so I thought I would try sending one. My friend gave me a large golden barrel pup from her father’s outside golden barrel cactus that lives in LA. I have been waiting for it to callus, and I went to check it today and the cut area was covered in a white fuzzy substance (pictures attached). I immediately thought of fungus, especially since it had been sitting in a box cut side down. I also thought it could be mealy bugs, and there was some orange color when I dabbed at it with alcohol on a paper towel, but not as much color as I would have expected if it was a dense mass of mealy bugs. I also looked at the cut surface and one of the pieces that came off with a 10x hand lens and I did not see any adults, just a dense matrix of white fluff. I had looked at it briefly when she brought it to me a week ago, and I do not recall seeing such a dense area of white fluff, although it was dark and I only looked very quickly. So whatever it is seems to have grown quite a bit in a week, although I can’t be 100% sure.

ย  ย 

I attached some pictures, in the last one the spots where the cut surface is orange is where I dabbed it with the alcohol on the towel. It seemed to dissolve from the alcohol, it didn’t really seem to rub off onto the paper towel.

Do you think this is fungus, mealy bugs, or something else, and can it be saved? I was admonished not to kill the cactus so I would be very disappointed if I lost it even before planting it. If you don’t just answer random questions, I understand but thought I’d give it a try!

Thanks,
Rachel

It’s going to be a problem since it’s winter, to treat this successfully. It’s a fungus and likely bacterial. I recommend sulfur on the cut edge and treat the whole plant with a systemic fungicide like Infuse, after the sun goes down. Keep dry! Air circulation. It will be at least a month before you can try planting it, and a heat mat under the pot might help it root (warm and dry).

Canary Islands Euphorbia Tree


Hi my name is jack.
I currently live in the canarys islands fuerteventura.
I have just took over a property to maintain there garden.
I am just looking for some advice how to prune the euphorbia candelabrum. The customer would like it reduced in height.
They are not particularly bothered about it flowing at this moment in time as it is round a pool area and would like it tidied up and reduced before guests arrive

Looking forward to your response
I have attached a photo.

Best wishes
Jack

Jack,

That is huge! Actually has pretty good form as is. Anyway, the trick with Euphorbias is that they have a poisonous sap so you have to wear a lot of protection, long sleeves gloves and eye protection. At that size it will probably take multiple people unless you have larger equipment available. We would use a crew of 4-5 people to safely cut that back.

You can cut any of the branches at the joints. That will reduce the overall mass. As for reducing the height, I don’t actually think that is possible. You could in theory remove all the branches and keep a tall stump which will start to grow back over time.

It’s a Bulb!


It’s the Oxalis namaquana, a rare little Wood Sorrel bulb with giant yellow flowers, as you can see. Usually most of the flowers are through the spring, but occasionally you get some through the winter. It’s a winter-growing bulb, so it can happen!

Can We Help with a Cactus ID?


Yes we can!

Dear Cactus Jungle,
I purchased a cactus from a garden centre in the UK. They were unable to tell me much about my purchase. I have been looking at your website and the cactus bears a striking similarity to opuntia monacantha variegata, which you sell

I just wondered whether you would be able to confirm whether this is the same type of plant. I have attached a picture of my cactus, for identification.

Best wishes,
Nicholas

You are correct!

Sedum or Senecio?


Hi there-

I found myself on your website when doing a Google search for the plant in the attached photo. I am a landscape designer in San Diego and a fellow designer suggested that it might be Sedum rupestre ‘Silver’; I’m not so sure because the plant height is more than 1′ high. Can any of you ID this plant for me, I sure would appreciate it.

Kind regards,
Kimberly
Past President, APLD San Diego District

Definitely not a Sedum. You can tell from the old flower stalk there it is a Senecio, probably Senecio haworthii.

Stay safe, Peter
