Choosing the Best Fertilizer for Fruit Trees
Growing fruit trees is rewarding, but it takes more than water and sunlight to produce healthy growth and delicious harvests. Fertilizer for fruit trees supplies the essential nutrients trees need for strong roots, steady growth, and plentiful fruit.
This guide explains the right time to fertilize fruit trees, how to select the best fertilizer for fruiting trees, and tips for applying fertilizer effectively without harming soil health.
Why Fertilizing Fruit Trees Matters
Fruit trees remove nutrients from the soil every year through growth and fruit production. Without replacing those nutrients, growth slows, leaves may yellow, and fruit becomes smaller or drops prematurely. Some trees also become more vulnerable to problems like fire blight.
Using the right fruit tree fertilizer helps prevent deficiencies, promotes good fruit set, and supports long-term tree health. Balanced feeding strengthens resistance to disease, improves fruit size, and ensures a steady harvest year after year.
When to Fertilize Fruit Trees
The best time to fertilize fruit trees is in early spring, just before buds begin to swell. At this stage, trees are waking up from dormancy and need nutrients to power new shoots, blossoms, and roots.
You can apply fertilizers again in early summer, but avoid fertilizing with nitrogen after July. Late feedings can produce tender new growth, which frost may damage.
For more guidance on dialing in your fertility plan, start with a home soil test and adjust based on growth and results.
Spring & Early-Summer Fertilization Schedule for Fruit Trees
| Tree Stage | Timing | Goal | What to Apply | Notes |
|---|---|---|---|---|
| Newly Planted (Bare Root or Young Trees) | At planting, then early spring | Support root establishment, not top growth | Compost + low-nitrogen root-focused fertilizer (such as PrimeStart Booster Blend) | Apply as a surface topdress, not in the planting hole. Keep fertilizer a few inches from the trunk and water in well. |
| Young, Non-Bearing Trees | Early spring (bud swell to early leaf-out) | Encourage steady structural growth | Balanced organic fertilizer or low-nitrogen blend (DTE Fruit Tree) | Avoid excessive nitrogen that can cause overly vigorous, weak growth. |
| Mature, Bearing Trees | Early spring (before bloom) | Support flowering, fruit set, and leaf growth | Balanced organic fertilizer based on soil test results | Apply evenly from 1 foot out from trunk to drip line. |
| All Trees (if additional feeding is needed) | Early summer (after fruit set) | Maintain healthy growth and fruit sizing | Light side-dressing of nitrogen if growth is weak | Do not apply nitrogen after mid-summer to avoid late, frost-tender growth. |
Important Seasonal Reminder:
Avoid nitrogen applications after July in most climates. Late fertilization can stimulate soft new growth that is vulnerable to winter injury and can reduce fruit quality the following season.
How to Decide If Your Tree Needs Fertilizer
Not every tree needs feeding each year. Instead of guessing, measure the previous year’s growth:
- Young apple trees and pears: 18–30 inches
- Mature apple trees and pears: 12–18 inches
- Young sweet cherries: 22–36 inches
- Mature cherries: about 8 inches
- Peaches and nectarines: 12–18 inches
If growth falls below these ranges, it’s a sign that the tree may be short on nutrients and could benefit from fertilization. However, if you removed more than about 20% of the canopy through pruning the previous season, hold off on adding extra fertilizer. Heavy pruning naturally stimulates vigorous new growth by reducing the number of buds competing for stored energy. In this case, the tree may already produce strong shoots without additional nitrogen, and fertilizing too soon can push excessive, weak growth at the expense of fruiting and long-term structure.
Types of Fertilizers for Fruit Trees
The best fertilizer for fruit trees depends on soil health, tree age, and crop type. Before feeding, have your soil tested with a professional soil test or try a home soil test kit to check soil pH and nutrient levels. A soil test helps you avoid over-fertilizing and makes it easier to choose products that address what your trees actually need.
Here are common fertilizer choices and why they’re useful in an orchard:
Organic Fertilizer Options
- Chicken manure or Sup’R Green chicken manure – a classic orchard amendment that provides slow-release nitrogen for steady spring growth. Because it breaks down over time, it supports greener leaves and stronger shoot growth without the quick “flush” you can get from synthetic fertilizers. Use composted or partially composted materials and apply as a surface topdress under the canopy.
- Soybean meal – a plant-based organic nitrogen source that feeds trees gradually and also supports soil biology. It’s especially useful when young trees need consistent growth, or when soil tests show low nitrogen but you want a gentler, longer-lasting input than fast-acting fertilizers.
- Compost – the foundation of long-term orchard fertility. Compost improves soil structure, water-holding capacity, and microbial activity, which helps roots access nutrients more efficiently. Use compost annually as a topdress under the drip line, then mulch over it to keep the soil evenly moist.
High-Nitrogen Sources for Growth
When trees are clearly under-growing (short annual shoot growth, pale foliage, weak canopy fill), higher-nitrogen inputs can help—especially in spring. The key is to apply carefully and stop nitrogen applications by mid-summer in most climates to avoid tender late growth.
- Blood meal – a fast-acting organic nitrogen source that can quickly correct nitrogen deficiency and improve leaf color and early-season growth. Because it releases relatively quickly, it’s best used in measured amounts and applied as a surface topdress, then watered in well.
- Feather meal – a slower-release nitrogen source that feeds over a longer window than blood meal. This makes it a good option for maintaining steady growth through spring and early summer without as sharp of a growth spike.
Micronutrient Boosters for Fruit Quality
- Azomite – a broad-spectrum trace mineral amendment that can help fill micronutrient gaps in depleted soils. Micronutrients support enzyme function, flowering, and overall plant vigor.
- Langbeinite – a mineral source of potassium and magnesium that supports fruit sizing, sweetness, and firmness, while magnesium contributes to chlorophyll production and leaf health. It’s a useful choice when soil tests show low potassium or magnesium, or when trees are fruiting heavily and pulling more K from the soil.

How to Apply Fertilizers to Fruit Trees
- Measure tree age or trunk diameter to calculate how much to apply. A common guideline is about 0.10 pounds of actual nitrogen per year of age or inch of trunk diameter, up to a maximum of 1 pound for a mature tree. Adjust rates based on soil test results and annual shoot growth.
- Apply fertilizers evenly under the canopy, starting about 12 inches away from the trunk and extending out to the drip line, where the majority of fine, nutrient-absorbing roots are located.
- For nutrients that move slowly in soil, such as phosphorus and potassium, dig small holes about 6 inches deep and 12–18 inches apart around the drip line and place the fertilizer in the holes. A bulb auger makes this faster and helps position nutrients closer to the active root zone.
- After applying dry fertilizers, topdress with compost or other organic matter to protect soil life, reduce nutrient loss, and improve moisture retention, then water thoroughly to move nutrients into the root zone.
- Liquid fertilizers can also be applied as soil drenches or through drip irrigation during periods of active growth for quicker uptake. Learn how with our fertilizing fruit trees video.
How Much Nitrogen Do Fruit Trees Need?
| Tree Size / Age | Trunk Diameter (approx.) | Target Nitrogen per Year | Example Product Type | How This Looks in Practice |
|---|---|---|---|---|
| Newly Planted / 1st Year | ½–1 inch | 0.05–0.10 lb N | Low-nitrogen root starter (PrimeStart Booster Blend) | Light surface topdress in spring to support root establishment, not canopy growth. |
| Young Tree (2–3 years) | 1–2 inches | 0.10–0.20 lb N | Balanced organic tree fertilizer (Down to Earth 6-2-4) | Apply evenly from 12" out to the drip line in early spring. |
| Developing Tree (4–6 years) | 2–4 inches | 0.20–0.40 lb N | Organic orchard blend or composted poultry manure | Split between early spring and (if needed) early summer. |
| Mature Bearing Tree | 4"+ | 0.40–1.0 lb N (max) | Soil-test-guided organic blend + compost | Apply once in early spring; avoid late nitrogen after early summer. |
Special Tips for Young Trees and Planting Holes
For young trees and new plantings, focus on healthy root establishment rather than rapid top growth. When setting out bare root apple trees or other stone fruits, incorporate finished compost into the backfill soil to improve structure, moisture retention, and microbial activity — all essential for strong early root development. Avoid placing high-nitrogen fertilizers directly in the planting hole, as concentrated nitrogen can burn tender new roots and encourage vigorous shoot growth before the root system is ready.
To support root growth without overstimulating shoots, a low-nitrogen fertilizer formulated for bare root trees can be helpful. For example, Peaceful Valley Organic PrimeStart Booster Blend is designed specifically for use at planting. It contains slow-release phosphorus and a balanced mix of micronutrients that help roots establish and promote healthy flowering later in the season, with lower nitrogen than typical orchard fertilizers to match the nutrient needs of newly planted trees.
Apply the fertilizer as a light surface topdress after planting, keeping it a few inches from the trunk and watering it in well. Combined with compost in the backfill, this approach provides nutrients where and when young roots can access them without overwhelming the tree during its critical establishment phase.

Really informative guide—thanks for breaking down the different fertilizer types and timing. I’ve had decent results with citrus fertilizers, but lime trees seem a bit pickier than other fruit trees. For anyone specifically working with lime trees, I put together a detailed post on the best fertilizer for lime trees and how to apply it for healthy growth and high yield. Hope it’s useful!
Love the information 👌
Katheline, for your galls, it is best to take a sample to a local nursery for diagnosis. The peach leaf curl should be treated in the dormant season, typically 3 sprays (after leaf drop, at new years and again around valentines day, or before blossom opening). You can use any good fruit tree fertilizer to fertilize your trees. Might be late this year to fertilizer, unless the fertilizer has low to no nitrogen. You just don’t want to stimulate a bunch of new growth that may not be hardened off before winter.
John, figs typically do not need much supplemental fertilizers. Sounds like you are giving them too much nitrogen. I would work in some compost and wait to fertilize again until next year. When you do give them a fertilizer with more phosphorus than nitrogen.
I have a number of potted fig trees. Some years we get a nice amount of figs and some years they don’t produce much (if any). I used a balanced 10-10-10 fertilizer (which had been recommended for figs) in the spring along with some processed manure from a garden supply about a month later. The figs that were there 2 months ago haven’t really grown much but there is so much new growth in leaves. Can you tell what might be going wrong? Thanks.
