How to fertilize Arizona Thistle
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 Arizona Thistle after it doubles in size or once a year—whichever comes first.
