How do I keep my cactus Dormant if I have to bring them into a house with no cold areas? Also that wide short cactus on the front left with all those little clumps is amazing. I didn't catch the name
Plant naturally go through a phase of dormancy in months of winter . It’s better to keep them in a green house with lots of light or near a place where they can get some sunlight . In places where temperature go below 3 degrees it’s better to keep them inside . Just use a potash and phosphorus rich fertiliser in a month of feb and March and you will see the results. Shift them in outdoors if temperature go up for long life .
