Cacti Question

[SPedigrees]

I planted these little guys from seed about 10 years ago and they seem ok but haven't grown much at all in the last 5 years. They are on a windowsill that gets a fair amount of sunlight in summer, but sunlight is scarce here in winter. Also this room tends to be warmish even with the A/C in summer, but a few degrees cooler than the 68F of the rest of the house in winter. After causing death by drowning of former cacti (RIP) I instituted my present watering system, which is that I check the weather in Phoenix AZ every day and when it rains there I give 2 tblsp of water to the cacti.

The thing is that, given climate change, Phoenix has been suffering extreme heat in recent years, causing damage and death to many Saguaro and other native plants. So, while my little cacti, if anything are not getting temperatures warm enough, they are at least protected from the current Arizona heatwave. But I wonder if they also are not getting the water that they need. With my past history, I'm reluctant to increase their water supply, but do you all think they need more?

The diorama in the foreground contains no living things. My plan B if the little cactus family on the windowsill die, is to turn their little pot into a similar lifeless habitat, but I hope it doesn't come to that.

Some of the cacti/succulents grow very slow. I planted some small ones and in 2 years they didn't even grow an inch. If you want a fast grower, try hens and chicks. They come in a variety of colors too and they also hang down.

You can also try making a make shift greenhouse dome. A 2 liter soda bottle could work. Only my advice not any knowledge.

I would look at the weather in the SW deserts. When it rains There, water your cactus. As long as your soil drains well I cannot believe that you'll drown them. They probably Do need more water than you have been giving them.

That's what I do now.

The problem is that cacti in the SW deserts are now suffering and dying due to climate change's extreme hot temperatures. I suspect that these SW deserts are also suffering from drought, since rainfall there has been few and far between for the past couple years.

Maybe this is normal growth for them then. If they were suffering from lack of water, I wonder if I would know. Cacti can be hard to read!
