Fertilizing your plum trees is an important part of keeping them healthy and producing a bountiful crop year after year. In this article, we will focus on the NPK ratio that you should use when fertilizing your plum tree. We will discuss how to choose which NPK ratio to use, what each number in the NPK stands for, and give some tips on how often you need to fertilize your fruit-bearing plants.
What are the benefits of using fertilizer for plum trees?
Fertilizing plum trees has many benefits, the most important of which are an increase in yield and a decrease in pests and diseases. Fertilizer can also improve the quality of your plums, making them sweeter and juicier. Using fertilizer also helps keep your tree healthy, ensuring that it will produce fruit for years to come.
How to fertilize the plum tree
Fertilizing plum trees is not an easy task. There are many things that you need to keep in mind when feeding your tree, including the time of year, the type of fertilizer, and the NPK ratio.
One thing that you should know about fertilizing your plum tree is how often it needs fertilizer. A small amount every month or two during planting season seems like a good idea at first glance but there are other factors involved too. It really depends on what kind of soil you have and how much water the plant gets each day. If all of these variables change over time then so will the amount of fertilizer that is needed.
When to fertilize the plum tree?
The best time to fertilize a plum tree is in the early spring before new growth begins. You can also fertilize in late summer, after harvest.
Fertilizing at these times will help stimulate new growth and encourage healthy fruit production. If you live in an area with a mild climate, you may be able to fertilize twice during the year. Be sure to follow the instructions on your fertilizer product for specific application rates and timing.

Choosing the right NPK ratio is important when fertilizing plum trees. The three numbers stand for nitrogen (N), phosphorus (P), and potassium (K). A balanced NPK ratio is crucial for optimal growth and fruiting. A high N number means that the fertilizer is high in nitrogen and is good for leafy growth. P-rich fertilizers promote flowering and fruiting, while K-rich fertilizers promote strong root growth.
When deciding on an NPK ratio for your plum tree, it is important to consider the age of your tree and the stage of its development. For a young orchard, use a balanced fertilizer with an NPK ratio such as 12-12-12 or 16-16-16. Mature trees should have a fertilizer that is lower in nitrogen and higher in phosphorus and potassium such as 0-20-20 to encourage fruit production.
Tips on how to maintain a healthy plum tree
Plum trees are not finicky, but they do require a good deal of work to keep them healthy and fruiting. While the tree is still young you should prune it every year, cutting off dead branches and shaping the structure of the tree so that there is ample space for fruit production. Once your plum has grown too large for this type of maintenance (usually after about three years), then you can simply cut back any new growth that may threaten other parts or limbs on the tree. You will want to fertilize plums once a year in early spring before flower buds appear- ideally during February or March when conditions are right for root development without encouraging excessive top growth which would result in self-shading by summertime.
