Flowering Fertilizer

Flowering Fertilizer is a bloom booster that runs alongside your regular feed, so its schedule sits on top of the one you already have. In spring and summer, mix 1–2 teaspoons per gallon and apply once a week; in fall and winter, drop to every 4–8 weeks as blooming winds down. A hose-end sprayer on the 2-teaspoon setting covers beds quickly, and you can mist leaves with 1 teaspoon per quart weekly if you like. Keep your complete fertilizer going underneath it.

Two usual causes: too much nitrogen or too little light. Nitrogen tells a plant to make leaves, and lawn fertilizer drift or heavy all-purpose feeding keeps a mature plant in that mode. Most flowering plants also won’t set buds without enough direct sun, and no fertilizer overrides shade, so check the light first. If light is right, Flowering Fertilizer addresses the nutrient side: its 0-10-10 formula adds phosphorus for bud formation and potassium to move sugars into flowers, without adding any more nitrogen.

No, and that’s by design. Flowering Fertilizer carries no nitrogen at all, and every plant needs nitrogen for the foliage that powers blooming; a plant fed only 0-10-10 over the long term will pale and stall. Keep your complete fertilizer as the base nutrition and add this as the bloom push. It’s built to work with all TPS products, and the two schedules are designed to run together: the regular feed builds your plant, and the phosphorus and potassium here direct it toward flowers.

Start as plants approach their bloom window, when buds should be forming, and apply Flowering Fertilizer weekly through the flowering season. For repeat bloomers like roses, keep going between flushes so the phosphorus and potassium are there to fuel the next round. For spring bulbs, feeding after the flowers fade helps the bulb store energy for next year. As blooming winds down, taper to the fall and winter schedule of every 4–8 weeks, and resume the weekly pace when the next season’s buds begin.

It supports fragrance rather than creating it. Sulfur is a building block of many of the volatile compounds that give roses, jasmine and other scented flowers their perfume, and it washes out of containers and sandy beds faster than most growers expect. Flowering Fertilizer carries 1% sulfur so a fragrant variety has what it needs to produce its full scent. It won’t add fragrance to a variety that doesn’t have it; genetics set the ceiling, and nutrition helps your plant reach it.

It depends on where your plants are in their cycle. Plants already forming buds respond fastest to Flowering Fertilizer, with fuller, longer-holding blooms within 2–3 weeks, since the potassium phosphate and potassium sulfate are soluble forms roots take up quickly. Shifting a leafy plant into flowering takes longer: expect the first new buds after 3–6 weeks of weekly use, because your plant has to initiate them from scratch. Season matters too; no booster forces bloom outside a plant’s natural window.
