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 Pencil Cactus after it doubles in size or once a year—whichever comes first.
What other plant parents say
I have had experience with many different varieties of pencil cactus. They are all extremely hardy. Sometimes it can be tricky to figure out the best propagation method, but once you have that down, you can multiply your plant without limit. With a proper pot and lighting, it will grow as large as the room you keep it in. My oldest plant reached the ceiling (about 8’) from a 3” propagation after about 8 years. I have a variety of other pencil cactuses. One is about 18 months old and about 3 feet tall. They don’t grow much in the winter unless you have a grow light. There is such a thing as too much light, but they are usually happy in spurts of direct sunlight. They don’t need much water, but they can handle quite a bit as long as they have proper lighting. Repot whenever the growing lulls during the growing season to keep it happy.
