Lemon Tree Fertilizer is a liquid fertilizer made for lemon trees — Meyer, Eureka, Lisbon and Ponderosa — in pots or in the ground. It is a 3.6-3-5.1, with more potassium than nitrogen, for a tree that flowers and carries fruit for most of the year on top of holding its leaves. Potted and planted trees take the same mix.
Mix it into a watering can, or run it through a hose-end sprayer for a tree in the ground. Feed every week or two in spring and summer, about monthly in fall and winter.
“2,weekend in a row, I used them for my citrus plants. Leaves colour and new leaves are coming out too. Now waiting for to see few flowers. Amazing. By the way temperature is over 100 for last several weeks now. Waiting for some rain and cooler days too.”

Every 1–2 weeks
Direct, bright light, eight or more hours a day. Indoors, use the sunniest south window, and move potted trees outside once nights stay above 50F.
Water heavily, then let the soil dry out mostly before the next round. Lemons drop leaves and young fruit from drought and from a pot left standing in water.
A fast-draining mix with sand and perlite, pH 6.0 to 7.0. Citrus roots need air at all times, so skip heavy garden soil in containers.
Happiest between 55 and 85F. Bring potted trees indoors before frost, since most lemon varieties take damage once temperatures drop near 30F.
Feed Lemon Tree Fertilizer every one to two weeks in spring and summer, and every four weeks in fall and winter, at 2 tablespoons per gallon of water.
Prune lightly after the main harvest to shape the tree and open its center to light. Cut off any shoots that sprout below the graft union at the base.
Lemon Tree Fertilizer is a 3.6-3-5.1 formula built around what a fruiting citrus draws on: nitrogen for leaves and shoots, potassium for fruit development, calcium, magnesium and iron for deep green foliage, and the trace elements such as zinc and manganese that citrus commonly run short of. Feed every week or two in spring and summer, when the tree is growing, flowering and setting fruit, and about once a month in fall and winter, at 2 tablespoons in a gallon of water.
Fast-acting. All of the nitrogen is nitrate, the form roots absorb directly, and the whole formula is dissolved in water when you apply it, so the tree is fed the day you water. That’s why it goes on as a schedule rather than once a season: citrus feed heavily through the growing months, and a liquid lets you match the supply to that instead of leaving a granule to release on its own timetable.
Yes. A potted lemon depends on you for nutrition more than one in the ground, because regular watering carries nutrients out of the container. Use the same 2 tablespoons per gallon on the same schedule, in a fast-draining mix with some sand and perlite, watering thoroughly and letting the soil dry mostly between waterings. Feed as part of one of those waterings.
It depends on why they’re yellow. On citrus, pale or yellowing leaves most often mean a shortage of nitrogen, magnesium or iron, and Lemon Tree Fertilizer supplies all three along with manganese and zinc, so a hungry tree greens up in its new growth. If the yellowing comes from overwatering, cold or root trouble, no fertilizer will fix it; rule those out first.
Lemon Tree 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. Mixed at 2 tablespoons per gallon and applied every week or two in season, the nutrients arrive in solution at a strength the roots take up as they water. Keep to that mix and water it in as part of a normal watering. If you miss a feeding, pick the schedule back up at the normal rate.
In the new growth. Leaves that are already yellow or damaged won’t recover, but the flush of leaves and shoots the tree produces after you start feeding is where the difference shows first, and steady potassium through the season supports the fruit that follows. Feeding a lemon tree is a season-long routine rather than a one-time fix, which is why it goes on every week or two through the growing months.
