Peach Tree Fertilizer
Support peach trees through healthy spring growth, flowering, and fruit development with a liquid fertilizer made for productive trees.
Mix it into your normal watering routine as directed for simple, consistent feeding through the growing season.
Why You'll Love It
- Fruit Development Supports fruit size on peaches and nectarines carrying a full load.
- Steady Growth Feeds strong spring growth on standard, semi-dwarf and dwarf trees.
- Bloom Support Nutrition through a heavy bloom, so more of it sets into fruit.

Liquid peach tree fertilizer with a 3.6-3-5.1 NPK plus kelp. Supports strong spring growth and better fruit set.
How to Use Peach 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 heavy-cropping stone fruit. Peaches grow fast and set fruit prolifically, so nitrogen at 3.6% fuels the vigorous spring growth that supports the crop, and potassium at 5.1% — the highest of the three — drives fruit size, sugar, 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 peaches need.
Beyond NPK: sea kelp (Ascophyllum nodosum) for natural growth compounds, plus calcium at 2.1% — unusually high, and what firms flesh and strengthens new growth — magnesium (0.75%), iron, manganese, zinc, boron, and copper. Boron and zinc matter especially for peaches: shortfalls show up as poor fruit set and small, misshapen fruit, both common in stone fruit.
Made For
Every peach and nectarine: standard, semi-dwarf, and dwarf trees, and all common varieties from Elberta and Redhaven to donut and white peaches — young trees through mature bearing trees, in the ground and in large containers.
Problems It Solves
- Poor fruit set after a heavy bloom
- Small fruit — often from an overloaded, unthinned tree
- Yellowing leaves and weak spring growth
- Slow growth on young or newly planted peaches
FAQs
How often should I feed my peach tree?
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 — peaches carry a heavy crop and grow fast, so consistent feeding supports them better than a couple of heavy applications a year.
Why is my peach fruit small? Will feeding fix it?
Small peaches are most often caused by an overloaded tree, not underfeeding. Peaches set far more fruit than they can size, so thinning to about 6–8 inches between fruits early in the season is what produces large peaches. Feed steadily to support the crop, but thinning is the single biggest factor in fruit size.
My tree bloomed but set little fruit — why?
Peaches bloom very early, so a late frost killing the blossoms is the most common cause of poor set. Boron and zinc shortfall can also limit set, and both are in the formula. Most peach varieties are self-fertile, so pollination is rarely the issue — frost and nutrition are the usual factors to check.
Will this burn my tree?
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 peaches still establishing, start at half strength for the first two feedings.
When will I see results?
New growth greens up within the first few weeks of feeding, and fruit quality follows the season's crop. Consistently fed and properly thinned peach trees produce larger, sweeter fruit, and the benefit compounds year over year as the tree builds strength.
