Should You Fertilize Your Rosemary Plants?

Rosemary is such a vigorous grower; it seldom needs fertilizer. But if growth is slow or stunted, or appears pale yellow, use fertilizer once in early spring before new growth begins.

You can use any all-purpose fertilizer, preferably a 5-10-5 or 10-10-10, in liquid or dry form. Be sure to apply the fertilizer to the root area, avoiding the plant itself as fertilizer can cause leaf burn.

You may also use a foliar spray in mid-season if you desire, to keep your plants healthy.

Alternately, you can use a top dressing of organic material in the spring instead of fertilizer.
