Maple Tree Fertilizer
Support healthy roots, a full canopy, and strong seasonal growth with liquid fertilizer made for maple trees. It is suited for large shade maples as well as ornamental Japanese maples in landscapes or containers.
Mix it into your normal watering routine as directed for consistent feeding without making tree care complicated.
Why You'll Love It
- Steady Growth For slow growth on young or newly planted maples.
- Strong Canopy Supports a full canopy on a shade maple rather than a thin one.
- Healthier Soil Feeds trees showing pale leaves with green veins.

How to Use Maple 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 shade and ornamental tree. Nitrogen at 3.6% fuels the spring flush and full canopy maples are prized for, and potassium at 5.1% — the highest of the three — drives root strength and the wood strength that carries a tree through wind and cold, and supports strong fall color. All of the nitrogen is nitrate nitrogen, the form roots absorb directly, so response is fast and burn risk stays low — which matters for sensitive types like Japanese maple.
Beyond NPK: sea kelp (Ascophyllum nodosum) for natural growth compounds, plus calcium at 2.1% — unusually high, and what strengthens new growth and roots — magnesium (0.75%), iron, manganese, zinc, boron, and copper. Manganese and iron matter for maples in particular: a shortfall shows as pale, yellowing leaves with green veins, common where soil is alkaline.
Made For
Every maple: large shade maples like red, sugar, silver, and Norway, and ornamental Japanese maples (Acer palmatum) in upright and weeping forms — young trees and established specimens, in the landscape and in containers.
Problems It Solves
- Pale or yellowing leaves with green veins
- Thin canopy and weak spring growth
- Slow growth on young or newly planted maples
- Poor or muted fall color
FAQs
How often should I feed my maple tree?
Every 1–2 weeks during spring and summer while it's actively growing, and every 4 weeks in fall and winter. Diluting into your regular watering (2 Tbs per gallon) keeps nutrition steady — this gentle, consistent approach suits sensitive maples like Japanese maple far better than a heavy single application.
Is this safe for Japanese maples?
Yes — the gentle, all-nitrate formula and low salt concentration are well suited to Japanese maples, which are sensitive to over-fertilizing and leaf burn. Feed at the label rate and no stronger, start new or recently planted trees at half strength, and avoid heavy late-season feeding, which pushes tender growth prone to scorch and cold damage.
My maple's leaves are pale with green veins — will this fix it?
That pattern is usually iron or manganese shortfall, common for maples in alkaline soil, and both are in the formula. New growth should green up within a few weeks of regular feeding. If your soil is very alkaline, the discoloration can recur, so persistent cases may also need the soil pH lowered.
Why are my Japanese maple's leaves browning at the edges?
Edge browning, or leaf scorch, usually comes from too much sun, wind, dry soil, or over-fertilizing — not a nutrient shortage. Feeding at the correct gentle rate avoids the fertilizer cause. Japanese maples do best in part shade with steady moisture, so shelter and consistent watering matter as much as feeding for clean foliage.
When will I see results?
New growth greens up within the first few weeks of feeding during the growing season. Maples grow at a moderate pace, so filling in a thin canopy takes a season or more — color and vigor respond first. Stronger, well-fed trees also tend to show better fall color.
