Give your orange tree consistent nutrition for healthy green leaves, fresh growth, flowers, and developing fruit with our liquid Orange Tree Fertilizer. Its 3.6-3-5.1 formula includes calcium, magnesium, and iron. Easy to mix with water, it fits into caring for orange trees in containers or in the ground when they're actively growing.
Your orange tree needs nutrients for both new foliage and the energy-intensive process of developing fruit. Our liquid citrus-focused formula makes supplemental feeding simple as growth resumes and the tree moves through flowering and fruit development.
Are your orange tree leaves yellowing? Low nutrient availability is one possibility, but citrus can also respond to poor drainage, cool conditions, or soil pH that limits iron uptake. Adding extra fertilizer without checking those factors may not help.
Container orange trees have less soil to draw nutrients from than in-ground trees and may need closer attention. Follow label directions, and adjust the overall feeding plan to your tree's age, growing conditions, and seasonal activity—not simply the number of oranges on the branches.
Why growers choose it: Orange-tree-focused 3.6-3-5.1 liquid nutrition, label-verified micronutrients, and easy feeding for pots or gardens.

Yellow citrus leaves aren't always a fertilizer problem. Check watering, drainage, and soil pH, especially if new leaves are yellow between green veins.
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.

Oranges want eight hours of direct sun. Indoors or on a patio, use your sunniest spot and move your tree outside once nights stay above 50F.
Water deeply when the top two inches of soil dry out, then let it drain. Citrus roots hate standing water, but drought stress drops flowers and small fruit.
Sandy or loamy soil that drains fast, at pH 6.0 to 7.0. In pots, use a citrus or cactus mix rather than dense, moisture holding potting soil.
Feed Orange Tree Fertilizer every two to four weeks from late winter through summer while your tree is flowering and setting fruit, then ease off in cold months.
Prune lightly in early spring to open the center and remove dead wood. Always cut off suckers below the graft union, since they are not the fruiting variety.
Oranges ripen on your tree and do not sweeten after picking. Navels are usually ready in winter and Valencias in spring; taste one before harvesting the whole tree.
Orange Tree Fertilizer is built for steady feeding through the months when citrus is growing and carrying fruit. In spring and summer, feed every 1–2 weeks: 2 tablespoons per gallon in a watering can across the root zone, or the 1-ounce setting on a hose-end sprayer for a larger tree. In fall and winter, cut back to once every 4 weeks; citrus slows in cool months and doesn’t need the same pace. Keep the soil evenly moist between feedings so the roots take up the solution.
Usually it isn’t nutrition. Young trees under three years often drop their bloom until they mature, and even an established tree sheds most of its flowers; a small fraction turning into fruit is normal. Inconsistent watering, temperature swings during bloom and a lack of pollinators matter more here. Orange Tree Fertilizer supports the canopy and the fruit your tree does hold, with potassium leading the formula for fruit size and skin quality, but it can’t make a tree carry fruit it isn’t ready for.
Where the yellow appears tells you the cause. Yellowing between the veins on older leaves usually points to magnesium; the same pattern on new tip growth points to iron, common in potted and alkaline-soil citrus. Orange Tree Fertilizer carries both, along with manganese and zinc, so new growth has what it needs. Uniform yellowing across whole leaves, or yellowing with leaf drop, more often means overwatering or poor drainage. Check that the soil dries partway down between waterings before treating it as a feeding problem.
Yes. Orange Tree Fertilizer is made for oranges in containers as well as in the ground, and its nitrate nitrogen is absorbed directly by the roots, which suits a pot where roots sit close to the fertilizer. Use the same 2 tablespoons per gallon. Potted citrus loses nutrients faster because frequent watering washes them out of the mix, so the every-1–2-weeks schedule in spring and summer matters more indoors than for a tree in the garden. Make sure the pot drains freely.
Feeding helps the fruit reach its potential; sun and time on your tree do the rest. Orange Tree Fertilizer runs potassium highest, and potassium supports sugar development and skin quality, so a well-fed tree isn’t held back on either. But sweetness is driven mostly by sunlight and ripening, and oranges don’t sweeten after picking. Give the tree full sun, feed on schedule, and leave the fruit to hang until it’s fully colored and slightly soft before you harvest.
Roots and foliage respond first, usually within a few weeks of starting Orange Tree Fertilizer, since the nitrate nitrogen is available to your tree as soon as it’s watered in. Magnesium or iron yellowing corrects on new growth over several weeks; leaves that have already yellowed won’t re-green, so judge by what comes in next. Fruit size and skin quality follow the tree’s seasonal cycle, so the clearest gains show across the next fruit set rather than the current one.
