Fruit Tree Fertilizer
Support healthy growth, flowering, and fruit development across apples, stone fruit, and other common fruit trees. This liquid fertilizer is made to provide consistent nutrition through the productive growing season.
Mix it into your normal watering routine as directed for straightforward fruit-tree feeding.
Why You'll Love It
- Fruit Development Supports fruit set and size on apple, pear, peach, plum and cherry.
- Steady Growth Feeds young whips and mature trees that must grow and crop in one season.
- Bloom Support Nutrition through bloom, so heavy flowering has a chance to become fruit.

Liquid fruit tree fertilizer with a 3.6-3-5.1 NPK plus kelp. Supports strong growth and better fruit set on apples, stone fruit, and more.
How to Use Fruit Tree Fertilizer
| Method | Amount | How Often |
|---|---|---|
| Watering can | 2 Tbs (30 mL) per gallon of water | Spring & summer: every 1–2 weeks |
| Watering can | Same dilution | Fall & winter: every 4 weeks |
| Hose end sprayer | Set dial to 1 oz (30 mL) setting | Spring & summer: every 1–2 weeks |
| Leaf misting (optional) | 1 tsp per quart (32 oz) of water | Every 1–2 weeks |
Mix into your normal watering — no separate feeding routine needed.
What's Inside
The 3.6-3-5.1 ratio is built for a tree that has to grow and fruit in the same season. Nitrogen at 3.6% fuels the spring flush and canopy that feed the crop, and potassium at 5.1% — the highest of the three — drives fruit size, sugar development, and firmness. All of the nitrogen is nitrate nitrogen, the form roots absorb directly, so response is fast and burn risk stays low in the well-draining soil fruit trees need.
Beyond NPK: sea kelp (Ascophyllum nodosum) for natural growth compounds, plus calcium at 2.1% — unusually high, and the nutrient most tied to firm flesh and fewer storage disorders like bitter pit — magnesium (0.75%), iron, manganese, zinc, boron, and copper. Boron and zinc matter especially at bloom, where a shortfall shows up as poor fruit set and small, misshapen fruit.
Made For
Every common fruit tree: apple, pear, peach, plum, cherry, apricot, nectarine, fig, and pomegranate — young whips through mature bearing trees, in the ground or in patio containers.
Problems It Solves
- Poor fruit set after a heavy bloom
- Small or misshapen fruit
- Yellowing leaves and weak spring growth
- Slow growth on young or newly planted trees
FAQs
How often should I feed my fruit trees?
Every 1–2 weeks during spring and summer through growth and fruit development, and every 4 weeks in fall and winter. Diluting into your regular watering (2 Tbs per gallon) keeps nutrition steady — fruit trees carry a heavy crop load and do better on consistent feeding than a couple of heavy applications a year.
My tree bloomed but set little fruit — will this help?
Poor set after a good bloom often traces to boron and zinc shortfall, both of which are in the formula and both critical at flowering. Feeding also isn't the whole story — fruit set needs pollination and, for many trees, a compatible pollinator nearby. But correcting the nutrition removes one of the most common limiting factors.
When should I stop feeding for the year?
Feed every 4 weeks through fall, but ease off before hard dormancy — late-season nitrogen pushes tender growth that won't harden before frost. Resume in early spring as buds break. This timing matters most in cold-winter climates; warm-zone trees can stay on the lighter fall schedule longer.
Will this burn my trees?
No — at the directed dilution, the formula is designed for regular use. All-nitrate nitrogen and low salt concentration make burn very unlikely, even on young trees. For newly planted or bare-root trees still establishing, start at half strength for the first two feedings.
Can I use it on potted and dwarf fruit trees?
Yes, at the same dilution. Container and dwarf trees benefit most, since potting mix runs out of nutrients faster than orchard soil. Use the watering can rate for pots and the hose end sprayer for in-ground trees.
When will I see results?
New growth typically comes in greener within the first few weeks of regular feeding. Fruit quality improvements follow the tree's seasonal cycle — consistently fed trees size and finish fruit noticeably better, and the difference compounds year over year as the tree builds reserves.
