Tree Fertilizer
Tree food with a full-spectrum 3.6-3-5.1 NPK, kelp, and a complete micronutrient package — made to feed shade trees, evergreens, ornamentals, and young plantings through steady seasonal growth. Potassium supports root strength and winter hardiness, while calcium, magnesium, and iron keep canopies deep green instead of thin and pale.
How to Use 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 the 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 |
Use a well-draining soil with some water retention, and let it mostly dry between waterings — most trees prefer moderate to high watering without sitting wet.
What's Inside
The 3.6-3-5.1 ratio (3.6% nitrogen, 3% phosphate, 5.1% potash) is potassium-forward — nitrogen for canopy growth, potassium for root development and cold tolerance. All of the nitrogen is nitrate nitrogen, the form roots take up directly, for faster response and lower burn risk than ammonium-heavy formulas.
Beyond NPK: sea kelp (Ascophyllum nodosum) for natural growth compounds, plus calcium (2.1%), magnesium (0.75%), iron, manganese, zinc, boron, and copper — the micronutrients trees draw down over years in the same soil.
Made For
Trees of most kinds — shade trees, evergreens, ornamentals, and young or newly planted stock — in the landscape or in large containers. One bottle covers the whole growing season.
Problems It Solves
- Pale or thinning canopies on trees that haven't been fed
- Slow establishment on newly planted trees
- Weak spring growth after a hard winter
- Long-established trees showing gradual decline in the same soil
FAQs
How often should I feed my tree?
Every 1–2 weeks in spring and summer while the tree is actively growing, then every 4 weeks in fall and winter.
Can I use this on newly planted trees?
Yes. Nitrate nitrogen and a gentle labeled dilution make it suitable for young stock, and steady feeding supports root establishment through the first seasons.
What kinds of trees is this for?
Most landscape trees — deciduous shade trees, evergreens, and ornamentals. If you're feeding a specific fruit tree or a species with unusual needs, a targeted formula may suit it better.
How do I feed a large tree?
Use the hose-end sprayer at the 1 oz setting — it covers far more ground than a watering can at the same dilution.
Will this burn my tree?
Not when used as directed. All of the nitrogen is nitrate nitrogen, which is gentler than ammonium-heavy fertilizers, so the burn risk is low at the labeled dilution.
