6 Best Fertilizers for Peach Trees — A Buyers Guide

6 Best Fertilizers for Peach Trees — A Buyers Guide

The Peach tree originated from China, and the main reason for growing this is the juicy fruit in shades of orange, red, and yellow. 

Peaches can add a unique and refreshing taste to cupcakes, pies, or jams, especially if you have cultivated them yourself. 

But this delicious fruit tree needs regular maintenance and feeding to produce the healthiest fruit. 

If your Peach tree produces very few Peaches, has stunted growth and fruit size, you should evaluate the nutrients in the soil.  

Fertilization is an essential part of the annual care for Peach trees. 

Applying the best Peach tree fertilizer at the right time will enhance everything about the tree, the flower, fruit, and foliage. 

Expert gardeners recommend performing the leaf and soil analysis every year for the Peach tree. 

Did you know that the fertilization rate for Peach is higher than other types of fruit trees because it absorbs more minerals and nutrients from the soil? 

For this reason, the Peach fruit is rich in nutrients.

Fertilizing Peach Trees

If you want plump, juicy Peaches, you have to follow the instructions about the timing and rate of fertilization. 

If the soil tests indicate nutrient-rich, fertile soil, you might not have to add any fertilizer until the fruit production begins. 

The average Peach tree starts bearing fruit between the age of 2 to 4 years. 

So, they do not need much feeding during the initial years. 

But if you decide to feed the young Peach trees, know that they require less fertilizer than mature fruit-bearing trees.


Newly Planted Peach Trees

Wait for at least one week before adding plant food to newly transplanted Peach trees. 

Give the 2nd dose a month after the first one. Make sure you water the soil deeply after adding fertilizer. 


Young Peach Trees

Require feeding in March and May. 


Mature Peach Trees

If your tree is older than four years, it falls in the category of a mature Peach tree. 

They also require two applications, but you will have to increase the amount of fertilizer per application. 

You can start the fertilization after blooming but before the flower petals start falling. 

You should also add relevant plant food when the tree is growing in May. 

Post-harvest fertilization is also necessary if your tree produced fruits this season. 

You should stop feeding the Peach after mid-August. 

If your Peach tree is growing plenty of new foliage, you can reduce the application to once a year only. 

Vigorous leaf growth means that the tree is dedicating most of its energy to leaf growth. 

To balance this, either reduce the fertilization or feed with a fertilizer that focuses on fruit growth.


Everything About Peach Tree Nutrients

The leaf analysis is used to test the nutritional status of the mature Peach tree. 

A fruit-bearing established Peach tree needs to be fed twice per year. Most Peach growers add a feed in the early parts of spring and summer, as well as during late spring.

The two most important nutrients for fruit-bearing Peach trees are nitrogen and potassium. 

This is because these two are present in high concentrations in the Peach compared to other plant nutrients. 

Potassium is responsible for developing the disease resistance capabilities of the Peach tree. 

A young Peach tree needs plenty of phosphorus because it encourages healthy, strong roots and blossoms. 

Do not ignore the importance of other micronutrients. 

These are also needed for the overall health of the Peach tree. The most critical ones for this fruit tree are magnesium, sulfur, and calcium.

The first thing that is affected by the lack of nutrients is the appearance of leaves on the Peach tree. 

The leaves will be narrow or shrunken with a red tint. The leaves can also turn pale and develop dead spots on several areas. 

Both fruit-bearing and non-bearing trees need a regular supply of nitrogen. It contributes to fruit size, production, and overall Peach tree vigor.

The exact quantity of nitrogen needed varies depending on the age of your fruit tree, the overall fruit production, and the weed growth near the tree. 

However, avoid adding too much nitrogen as it might impact the fruit color and flower buds.

In some cases, nitrogen increases the risk of winter damage and extra leafy growth. 

The application time of nitrogen greatly varies on the soil type:

  • Sandy soil (around bud breaking or in spring)
  • Heavy soil (in early spring or winter before the swelling of buds)

Do not skip nitrogen feeding for non-bearing trees, or else, you’ll have a weak tree instead.

If your soil has sufficient nitrogen, the skin, flavor, and color of the Peaches will be better.

The ideal soil pH for this fruit tree is around 6.5. 

In addition to fertilizers, peat moss and compost also enhance the drainage, fertility, and water retention of the soil. These should also be added regularly for better growth of the tree. 


Tips for Fertilizing Peach Trees

  • Avoid placing the fertilizer close to the trunk of the Peach tree as it prevents the distribution of the nutrients to the roots and can damage the tree by causing fertilizer burns. 
  • I would recommend placing the fertilizer 8-12 inches away from the trunk of your fruit tree. This is the ideal range for the even distribution of nutrients throughout the soil near the root zone. 
  • The Peach tree prefers a dry summer for healthy growth, and they grow fruits on the branches from last year. Therefore, do not trim or damage the old branches. 
  • Generally, new trees require half a cup of fertilizer for the initial year. You can gradually increase this to 1 lb. once the tree starts maturing. Continue this rate until your tree is five years old. 
  • Once fully mature, a single Peach tree in your garden can consume up to 5 pounds of fruit tree fertilizer in a single application. 
  • A healthy Peach tree is identified by measuring tree growth every year. 12-18 inches of growth is the best for all Peach tree varieties. If the average growth on your Peach tree is less than 8 inches, you should immediately consider adding fertilizer in spring. 
  • If you are growing Peach in a frost-sensitive area, you should stop feeding two months before the first frost. 
  • Testing the soil is the most important step for fertilizing a Peach tree. It is important to understand that the number of elements in the soil can vary depending on the location and soil type. Always buy a fertilizer that feeds the soil with the nutrient that is missing. 
  • Avoid adding fertilizer to the planting hole for newly planted Peach trees. Fertilizer should be spread in the soil around the trunk. The best approach is to start a few inches away from the tree trunk and gradually move towards the drip line. 



Fertilizers can surely help you grow the best, home-grown Peaches. 

The fertilization for Peach trees will depend on the garden soil analysis and the growth rate of your tree. However, I would recommend focusing on the age and the tree’s location as well. 

A balanced fruit tree fertilizer ensures a steady supply of all three nutrients, nitrogen, phosphorus, and potassium.
