How to fertilize Blue Columnar Cactus
Most potting soils come with ample nutrients which plants use to produce new growth.
By the time your plant has depleted the nutrients in its soil it’s likely grown enough to need a larger pot anyway.
To replenish this plant's nutrients, repot your Blue Columnar Cactus after it doubles in size or once a year—whichever comes first.

Last night something happened and long story short my blue columnar plant fell. The pot shattered so I had to put it into a plastic pot. I was not happy because I just repotted it from a plastic into the clay pot a month ago. Is it too much to repot it, go through this and repot it again all within 2 months? Is it better to just keep it in the plastic pot for another year and let it rest. I did unfortunately lose one column that snapped off 😢.

Cactus Care Hi all! New plant owner here. I purposely chose to start with a cactus because it’s supposed to be an easy plant for starters. I need advice on proper love and care so I don’t kill this beautiful thing.

Can anyone help me with what to do with my cactus or if it’s ok? I was in a car accident and It got cut… I thought I cut out the bad spot… but it hasn’t grown much since and has a slight yellow tint to all of its needles. The roots are all good and intact. Thanks
