6 Best Peach Tree Fertilizers + When To Fertilize

Peach trees are an attractive investment for your yard or garden. With beautiful flowers, delicious fruit, and handsome foliage, what’s not to love about incorporating peaches into your landscape? With the right soil, water, and sunlight, they have an excellent opportunity to thrive and grow. However, you can always give them an extra boost by using the best peach tree fertilizers at the right time.

In this article, I’ll look at the best six fertilizers for peach trees and how to use them.

Choosing Fertilizer For Peach Trees

Peach tree fertilizers come in many different types and some are easier to use than others. Consider your budget, the amount of time you want to spend fertilizing your trees, and whether you prefer organic or inorganic methods when comparing formulas.

Fertilizer Spikes

Fertilizer spikes are easy to use because they are pre-measured. There are no messy liquids or granules to measure or spill, and the spikes easily store from one year to the next. Typically, fertilizer spikes only need to be applied one or two times per year, which is super convenient if you have a busy schedule or a tendency to forget!

To use them, hammer the spikes evenly around the base of the tree into the ground. You’ll want to place them around the tree’s dripline. This is the imaginary circle at the edge of the tree’s foliage. Although they are easy to use and store, fertilizer spikes tend to be a little more pricey than other methods.

Liquid Concentrate Fertilizer

Liquid concentrate fertilizer is a liquid that you dilute in water. This type of fertilizer is inexpensive, easy to mix, and — depending on the manufacturer’s directions — either sprayed on the ground or onto the foliage. It tends to get to work straight away and provides noticeable results within a couple of weeks.

This type of fertilizer needs to be applied the most often of all the different fertilizer types. But, on the flip side, it can burn your tree’s foliage if not mixed and applied correctly or if overused.


Granular fertilizer is usually worked into the topsoil. This can be done at the time of planting by placing it directly into the planting hole and then watering in. It can then be sprinkled around the base of your peach tree periodically during the growing season.

This type of time-release fertilizer can take a while to get to work on your peach trees. The good news is they continue to provide nutrients gradually, so there is no need to reapply as frequently as liquid concentrate.

The downside is that using granules can be somewhat messy and they may crystallize if not stored correctly.


Powder fertilizers are very economical and cost-effective to ship and store. Some are meant to be sprinkled on the ground around your peach tree and then covered with mulch or compost. Other types of powder fertilizers can be mixed with water and used like liquid concentrates.

For best results, don’t place these fertilizers too close to the trunk of the tree. Instead, apply them at least 8 to 10 inches away from the tree trunk for the fertilizer to be able to reach the roots.

Organic Vs Inorganic

Organic fertilizers are derived from animal or plant matter with many nutritional advantages. However, they often contain a low concentration of nutrients, decompose slower, and aren’t always ready-to-use.

Inorganic fertilizers are chemically produced and contain synthetic, concentrated amounts of potassium, nitrogen, and phosphorus. They also tend to have been laboratory-tested for performance.

These inorganic fertilizers are convenient products that are usually less expensive to buy than organic or natural peach fertilizers. They release chemical nutrients quickly into the soil, helping the plant to absorb them faster and more efficiently. Results are often visible much quicker than with inorganic fertilizers.

Peach Fertilizer N-P-K Ratio

A balanced fertilizer with an N-P-K ratio of 10-10-10 will work well on peaches. If you cannot find a 10-10-10 formula, you could also use another balanced fertilizer, such as 20-20-20 diluted by half.

If your peach tree has specific nutritional needs or is at a certain stage in the growing season, it’s worth considering a peach tree fertilizer that has a specific blend of N-P-K.

For example, opt for a higher ratio of nitrogen (N) if your soil is lacking in this nutrient and you have noticed your peach tree’s foliage is turning yellow and leaves are dropping. You may also experience delayed flowering and fruiting on your peach tree if nitrogen is lacking.

Conversely, too much nitrogen will cause your tree’s foliage to grow but may result in less fruit.

Phosphorus (P) helps plants use other nutrients to grow. If your soil has low phosphorus, your peach tree may have slow growth and very few flowers, resulting in a smaller harvest. Consider a fertilizer with a higher ratio of phosphorus if this is a problem for you. According to Clemson University, phosphorus is essential for younger trees.

Potassium (K) helps peach trees to grow stronger, resist pests, and produce more fruit. Without enough potassium, your trees may have brownish to yellow leaves and fail to thrive.

The right balance of nitrogen, phosphorus, and potassium will give your peaches the best opportunity for robust growth and a full harvest.

How To Feed Peach Trees

Ideally, you will want to feed fruit trees according to the manufacturer’s directions using a well-balanced N-P-K fertilizer.  Mix your fertilizer according to the directions and apply when planting your tree. Fertilizer needs to reach the tree roots, where it can easily be absorbed, so spread the fertilizer near the tree’s drip line and away from the tree’s trunk.

Trees less than 2 years old may not need as much fertilizer because they are not producing fruit yet.

When To Fertilize Peaches

If you choose a tree spike fertilizer, you’ll need to apply this fertilizer twice a year, in the spring and the fall. With other types of fertilizer, you will need to apply every 2 to 3 months during the growing season.

If your tree grows too quickly, you may need to cut back on the amount of fertilizer you are using.

How Often To Fertilize Peach Trees

Peaches need to be fertilized frequently unless you are using fertilizer spikes. Choose a spike fertilizer if you only want to fertilize twice a year—otherwise, fertilizer your trees every 2 to 3 months during the growing season.

Final Thoughts On Fertilizing Peaches

Choosing the right fertilizer for your peach trees largely depends on your time and budget. For an easy, fuss-free option go for a fertilizer spike such as a Jobe’s Organics Fertilizer Spike. Alternatively, why not try Dr. Earth Natural Wonder Fruit Tree Fertilizer? This really is a ‘wonder fertilizer’ and a great all round peach tree product. It is easy to use, cost-effective, and versatile.

No matter which fertilizer you use, there is no question that you will want to keep your trees looking… well… peachy, so always follow the manufacturer’s directions to ensure the best possible results.
