Plant appearance can also be affected by light, watering, roots, temperature, and other growing conditions, so feeding is one part of overall plant care.
Feeds foliage for deeper color and a brighter, more lively look.
Encourages fresh leaf and stem growth for a fuller, thriving plant.
Supports healthy, resilient roots that absorb nutrients more effectively.

Every 1–2 weeks
Six or more hours of direct sun, with morning sun preferred so the leaves dry early. Roses in part shade bloom less and hold leaf moisture longer.
Water deeply at the base twice a week in warm weather, about an inch each time. Keep water off the foliage and water in the morning.
Rich, well-draining soil at pH 6.0 to 6.8, with two inches of mulch over the roots kept an inch away from your canes themselves.
Feed Rose Fertilizer every two weeks from the first spring leaves until about six weeks before your first frost, mixed into water and poured at the base.
Prune in late winter or early spring as the buds swell, cutting to an outward-facing bud and taking out dead, spindly or crossing canes.
Deadhead spent flowers down to the first five-leaflet leaf to bring on the next flush. Knock Out and other shrub roses can be sheared lightly instead.
Rose Fertilizer is built for a plant that blooms in repeated flushes and uses up nutrients doing it. Mix 2 tablespoons per gallon of water and feed every 1 to 2 weeks in spring and summer while the roses are actively growing and blooming, then every 4 weeks in fall and winter. Roses are heavy feeders and rebloom best on steady nutrition mixed into your regular watering rather than occasional heavy doses; a hose-end sprayer set to the 1 ounce setting covers beds and large climbers quickly.
Yes, if feeding is the cause. Lots of foliage and few flowers usually points to nitrogen-heavy feeding pushing cane and leaf growth at the expense of blooms. Rose Fertilizer runs phosphorus at 3.6% and potassium at 5.1% above nitrogen at 3%, which keeps your rose's energy on flower production rather than leafy growth. Pair it with full sun and deadhead spent blooms so your plant puts its effort into the next flush rather than into seed.
Ease off as your rose goes dormant. Keep Rose Fertilizer on the every 4 week schedule through fall, then stop once growth halts and the leaves drop, since pushing tender new growth late in the season leaves it vulnerable to cold damage. Resume the every 1 to 2 week spring and summer schedule when new growth breaks in spring. In frost-free climates roses may bloom nearly year-round, and those plants can simply stay on the lighter every 4 week schedule through the cooler months.
Rose Fertilizer is a dilute liquid feed, and dilution is what matters here. Fertilizer burn happens when concentrated salts sit against the roots: too much product in too little water, or granules piled at the base of a plant. All of the nitrogen in the formula is nitrate at a low salt concentration; mixed at 2 tablespoons per gallon every 1 to 2 weeks in the growing season, the nutrients arrive in solution as part of a normal watering. Start newly planted or bare-root roses at half strength for the first two feedings.
Yes, at the same 2 tablespoons per gallon. Rose Fertilizer is formulated for roses as a group: hybrid teas, floribundas, grandifloras, climbers, ramblers, shrub roses and miniatures all share the same needs. Container roses benefit most, since potting mix loses nutrients with every watering and runs out faster than garden soil. Use the watering can rate for pots and the hose-end sprayer on the 1 ounce setting for beds and large climbers, where it reaches the whole root zone quickly.
New growth typically comes in greener within the first couple of weeks, since all the nitrogen in Rose Fertilizer is nitrate and available to the roots right away. Yellowing between the veins on older leaves, a common magnesium shortfall on roses, corrects on the new leaves as the magnesium in the formula reaches them. Bloom improvement follows your rose's own rhythm: consistently fed roses set heavier repeat flushes over the following weeks, and the difference shows most clearly in the second and third flush of the season.
