My seedlings are doing pretty well so far. Sown 6/16

Hi,

So we settled on this box for transplant, 30x30x30” that tapers down to 24” at the bottom. She’s been in the current 24” box about five years. We know which cactus soil we are going with, so now help is needed preparing the box.

I see that some people treat their wood planters with linseed oil to extend the life of the wood. Ideally this box will only need to last 3-5 years, so I’m not sure if treating the wood will be necessary.

Also, some of the spaces between boards are quite wide so I’m thinking of using landscape cloth to cover those and then drilling drainage holes. We will also set the box on heavy duty risers to preserve the bottom of the wood as long as possible.

The last hurdle will be trying to move the box to a new location a few years from now, as with soil/pumice/cactus it’ll prob be 4-500lbs.

Thoughts on preparation to make this a smooth transition are greatly appreciated. Thanks!

Hello, it will be my first winter with all these cacti, so I bought a greenhouse shelf to keep on my terrace, facing North-East.

I'm in Mediterranean weather, in zone 8 from my understanding. The terrace where I set up the greenhouse is quite sheltered from the wind. Is this going to be enough for them to survive the winter? Or should I put them inside?

Been raining the last couple of days out here and I found this guy outside sitting in a puddle of water basically so hopefully repotting helps! also it Came with a little buddy!! 😂

i only have a few cacti and these three have been my favorites. i've recently been getting into cacti more, stepping out of my plant comfort zone. 😅

i've tried searching for their species using image search, and i've only been getting the genus and not the main species. i'm really not the best in identifying cacti species apart, and i wouldn't trust image search that much and would love to know more from people who actually take care of cacti ❤️ would also appreciate care tips/ propagation tips!

are these gymnocalycium and ferocactus? and what are their specific names?

thank you 🌵❤️

Got these a while back at a greenhouse hoping they would make good root stock for other trichocereus. Any help identifying what they actually are would be appreciated!

Does anyone know what these lines could be from? They almost look like scratches

My Disocactus ackermannii has flowered for the first time in my care and did confirm that it's the true species. It's recognizable by the non-white stigma.

With the current heatwave I really needed to light up my cactus setup at night so I could keep repotting and admiring the collection!

I love that these can open 2 days in a row. The flowers are larger this year again. I dont think it liked being repoted last year that much.

So I have this cactus that I bought 2 years ago, and from the past months it started to do this strange fluffy flower, it is really a flower and how much it takes to blow?

Found this crested organ pipe while walking some washes Organ Pipe National Monument in AZ. Park service says they only know of about a dozen in the whole monument.

Why did my cactus turn black all of a sudden? I only want it every 4-5 weeks. I keep it indoors away from windows and between 68-78 degrees.

Crests, variegates, defaults, oh my!

This blob and a few white spots have appeared. I'm not sure what they mean. My other cactus also has a completely white side, but it continues to grow. I'm unsure what I'm doing wrong. I've had them for about four years.
