Thank u Peter for responding so quickly. I must admit i am sort of surprised that you wouldn’t have a market for such a handsome looking guy but there you go.

alright thanks again maybe you’ll see it someday sitting on the street corner forlorn, unwatered and untouched by neither human nor dog wandering by. Give It a fond glance wontcha?

Barbara

And what got Barbara to get poetic on us? Why this particular Euphorbia tirucalli right here:

Euphorbia tirucalli

Barbara asked if we wanted it since she has new grandkids and the plant is pretty poisonous, and we declined to take on this 5ft. tall x 4ft wide Euphorbia, attractive as it is. If anyone else local wants a referral to Barbara for this plant, let me know and I’ll pass along your information. Hopefully together we can forestall a “forlorn, unwatered and untouched” Firesticks.

Hello!
I’m writing you from the Netherlands. I was looking for a Dutch website that could help me out with my problem, but there doesn’t seem to be any.
I landed on your very helpful site, so I very much hope that you can help me out.

IMG_2206

I have a ammak since my birthday last August. It used to be standing in a light room, with no direct sunlight. After a while I started seeing green “fresh” looking tops arriving and took that as a good sign: that cactus seemed happy. (I must admit, I don’t know anything about cactus plants). I haven’t given it any water.

Recently I moved to another place. Bringing the cactus with us in the truck must not have been fun for him. It was a bumpy ride. Once it got to the new house, it was moved around a little bit and ended up behind some boxes in order to protect it. The house was freshly painted and smelled horrible (chemical) for weeks. It still does a bit.

Meanwhile. The ammak seemed to do fine, but after not paying too much attention to it for about a week, today, I suddenly noticed that a couple of his arms are turning brown!!!!

I’m soooo scared that something horrible is going on with him!

It seems that these cactus plants get “rot”, but as far a I can tell, that normally starts from the bottom. In this case, the discolouration mostly affects his arms and also his leg a bit, but there on the leg, there are mainly brown edged and just a bit of discolouration. I did notice that a couple of areas on the arms are also more “wrinkly” / mush, but not much. I also read about a fungus/virus.

Do you think that’s what’s going on?

I very much hope you can help me out!!
Thanks so much in advance!!

Unfortunately it doesn’t look good. I was surprised in your email when you said you hadn’t watered it since August. And then after the move that you kept it hidden behind boxes (where it presumably didn’t get light.) The move is going to be tough on any plants, but no water and no light is not something that a plant can survive.

In general if you get another one to try again I would recommend watering every 3 weeks. They should be in a very bright room or get a couple of hours of direct sun.

Hello,

If I remove the thorns from my cactus plant will the plant die, re-grow the thorns or continue to live without them?

Thank you

Vaddot

It should do just fine and continue to live without them.

Question? yes. Answer? yes.

Success!

Any idea what this might be ….?

None of the owners seems to know; it’s been a pass-along plant among neighbors. Sadly, I’m not a neighbor or I’d snag one.

Cheers,

Walt,

We don’t know the species but we think it’s some type of Kalanchoe.

Hello,

I’ve spent hours looking at pics online and can’t identify these cacti/succulents I recently acquired. Can you possibly identify them? Also, does the large brown swath on the prostrate plant indicate damage or a slow demise of some sort?

image image(2) image(3)

Thanks for any help you can give.

Newbie Leigh

The plants look like they need more sun, so it’s hard to ID them for sure. The one that is laying over is probably an Opuntia or less likely a Quiabentia. The brown is past damage and looks like it is fully healed.

The tall green one is maybe an Echeveria, like Echeveria setosa, but stretched vertically because of not enough sun.

The blue one is a Senecio, probably Senecio mandraliscae.

Hi Peter,

Are you able to offer advice on Haworthias? I have a Haworthia chocolate pictured below that is losing leaves one by one. Not sure if it is going to stop or not, and if this is normal for a healthy C. chocolate. The dying leaves will turn a bright red color while losing their firmness, then became a pale red, and even more soft before drying up completely. Any thoughts?

photo 1

Attached here is a picture of the specimen with leaves showing this activity.

I’ve searched the internet for information, but haven’t been able to find much about it.

Thank you for all of your help and time here.

David

David,

Given the natural brown coloration it’s difficult to tell for sure, but I think that it is just losing bottom leaves, which is normal for succulents. Maybe it’s been a bit more water than it wants? Hard to say from the photo. In moderate direct sunlight you should water every 1 1/2 weeks through the summer and in lower light less than that.

Nova Scotia calling. Hey guys, great website.

I wonder if you can identify this succulent a friend gave me. He got it in Italy and I am at a complete loss.

Halifax-20140808-02843

When he first sent a photo of it I thought it was an Aichryson or Aeonium.

When I got a piece I think maybe not, maybe an Echeveria hybrid???:

Hope you can help.

Will make a point to visit the nursery this winter.

Thanks

john

john,

That looks like a Sedum palmeri

Barbra Ann

Barbra Ann,

Nice flowers! The cactus is an Echinopsis eyriesii – Easter Lily Cactus. It’s called “barking” and the cactus is forming bark at the base of the plant with age.

Questions28 Jun 2014 09:26 am

Hi,

I was looking at your very helpful blog and was wondering if you had any insight to the below. My cactus recently had a bit of scale and once I removed it with a tooth brush it began to discolor with brown/black spots. I’m not sure if this is caused by the scale or if it is rotting and what my next steps should be. I bought some organic neem oil and treated it on Saturday evening but wanted to see with you if you think this is the right approach or what you would recommend. (I have attached a photograph for your reference) do you think there is any possibility this cactus could live?

photo-1

Additionally I have another cactus potted in the same pot which appears to be healthy but I wanted to see if you think it is ok to leave it or if I should repot the ‘sick’ one.

I look forward to hearing from you and thank you in advance for your help!

Olivia

Olivia,

I can’t tell what is going on from the photo. That wouldn’t have been caused by the scale. Generally we don’t recommend using a toothbrush since the bristles can be too firm – a soft paintbrush dipped in alcohol is sufficient to remove scale. It is possible that the skin of the Cereus was damaged and now has a fungus or other rot-related issues, but I can’t be sure. Neem wouldn’t have caused it unless you sprayed in direct sun, but it would help with any fungal issues. Or it can also be something entirely unrelated to the scale removal.

I would definitely separate the two plants, clear off all the soil from the clean one’s roots, and plant in a new pot with fresh cactus soil. If you live near Berkeley you could bring it in and we can help you with that.

Hello Peter,
I was wondering if you could help me take care of my plants and maybe give me some advice! So as you can see I love plants, especially cacti and perennial plants. In every picture you can see that the soil is wet because I just watered them all today. Can you tell me how often each one needs to be watered?

I would also like to know whether they should be outdoors or not? I have a garden where I could put them but I would rather have them with me in my room. I recently put 6 and 7 outside but I am worried about that ‘burnt look’ they have going on now… Maybe the transition was a little too abrupt since they used to be inside. I never changed the soils, could you tell me if I should and how to?

Can you also tell me if they look healthy or if one of them needs special care? For the ones that stay in my room, I try to let as much sunshine in as I can, but I think maybe they would like to be outside. Also some parts of 7 died and I don’t know what to do with the remaining parts, does it mean that the whole cactus is going to die too?

I don’t know that much about cacti but I love them and would hate for them to die, so please help me! I’ve had the euphorbia 5 for a few years, I keep it inside the house and it looks really happy to me, it has grown a lot! Most of the others are new and I can’t tell if they have grown or not.

I live in Paris and it is rather hot and sunny during the summer and spring, but it can get really cold in the winter.

Also, if you know their names I would love to learn! THANK YOU so much, I LOVE your blog, I really hope you get a chance to reply and maybe help me.

Albertine

Albertine,

When you bring plants outside they need to be “hardened off” to the sun, which means bringing them slowly out into sunshine over the course of a week or longer, or they will get a sunburn.

All plants can be grown outside, it just depends on your local climate. Here in Berkeley or San Francisco we can grow those outside, but I am not sure in Paris. There is a cactus shop there that might know better for your particular locale.

The plants that I know are:

1. Euphorbia ferox

2. Don’t know

3. Opuntia microdasys

4. Ferocactus, too young to know the species

5. Euphorbia – could be trigona

6 and 7. Mammillaria

Generally you can water them every 2 to 3 weeks, but they look like they’re not getting a lot of sun, so maybe every 3 weeks is best.

I am not sure what is going on with this Alluaudia. It seems to be having issues.

Michael,

That’s not good. I don’t know what it is. I would isolate the plant first. Then try dipping a paintbrush in rubbing alcohol and lightly rubbing to see what happens. But since I don’t know what it is, I can’t really help.

I’ll post it on the blog tomorrow and see if we get any responses there.

Questions12 Jun 2014 09:10 am

I recently became the caretaker of these plants. They have not had much
sunlight and I am acclimating them back into full sun over the next few
weeks. I am keeping them under a mesh tarp to let them get diffuse sun
and I plan to put them into larger pots with some fertilizer (3-3-3). Is
there anything that you can help me with based by just looking at the
picture or do you see any thing I should change with my plan? I am
guessing they are mostly some form of Euphorbia erythraea forma
variegata but am not really sure.

euphorbia ammak

Thank you for your time,
Rich

Rich,

Aside from the Opuntia which is the only cactus, the white ones are Euphorbia “Ammak” and the green ones are either the green version of “Ammak” or are probably Euphorbia trigona.

Depending on where you live they may need to be indoor. They are only hardy down around 32F, so we recommend them indoor in the SF Bay Area in the Winter.

Fast draining cactus soils for all of them. The cactus needs some good sun. The Euphorbias can handle light shade to full sun.

Do not fertilize a lot or these will grow into giant trees too quickly. Very little water – every 3 to 4 weeks should be fine, although more if it is sunny and hot.

Questions30 May 2014 09:41 am

Hello,

Yesterday I bumped my cactus, Mr. Popcorn, and on of his arms fell off/over. I’m not sure why…is this rot? What should I do about it?

IMG_2228

The soil is the soil he came with, with a little from the woods that I got several weeks ago and mixed in. Do I need to get a special kind? Also, could you tell me what kind he is? I’ve tried researching it but I’ve had little success.

IMG_2236

Here are some pictures.

Thank you so much!
Monica
P.S. Does he look healthy? Should he be greener?

Monica,

Your cactus is a Mammillaria elongata. The soil mix is too rich, and looks too wet. The arm has fallen over because of rot which was caused by too much water. Generally we recommend a fast draining cactus soil, no forest products. Water about every 3 weeks, and only a little more often in summer if it is in a hot and sunny location. Make sure the soil has completely dried out before the next watering.

You’ll need to cut out the rotted arm, digging out any rot in the soil too. I recommend spraying the base of the remaining plant with Neem Oil which is a natural fungicide and should help keep the rest of the plant from rotting.

Good luck

Peter

Questions24 Apr 2014 10:34 am

I have had this aloe in my backyard in Concord for almost 20 years. I have rarely watered it, because it was doing fine on its own. this winter after the big freeze, it was damaged. I have enclosed 2 pics. the plant is about 2.5 ft high, flowers almost 4 ft. What if anything should I do about its leaves? I trimmed some the dead tops off, is that the right thing to do? Would this plant survive being transplanted to a container? ( I know , no guarantees! ) its way in the back of my yard hidden behind a big rosemary bush.

aloe

Thanks for any advise!
Jeff

Jeff,

The Aloe looks fine overall. You can trim the ends if you want, but its not necessary – eventually they’ll take care of that themselves.

You might want to fertilize it this spring. We sell an organic fertilizer for succulents, Cactus Meal, or you can use a Kelp Meal too.

It should survive being transplanted, but it will take a hit since you’ll have to trim back the roots when digging it up. You might want to divide it when you get it out of the ground. Also, make sure to use a fast draining cactus soil.

Peter
