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.









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.
