About Black Ash

Black Ash likes soil that is well draining. Your plant shouldn't need added fertilizers if you repot each time it doubles in size.

How to fertilize Black Ash

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 Black Ash after it doubles in size or once a year—whichever comes first.
