The first thing you might be wondering is “what is 7-2-4 fertilizer?” Fertilizers are generally classified by how much nitrogen, phosphorous, and potassium they contain. The numbers represent the percentage of these nutrients in each bag. For example, a 25% ratio would mean that one pound of this type of fertilizer contains 3 pounds of nitrogen (N), 2 pounds phosphorous (P), and 1 pound potassium (K). Now we can get into what it means when someone says they’re using a 7-2-4 fertilizer. A lot has to do with the application rate but before we get to that let’s go over when to use it and what it does for your plants.
What is 7-2-4 fertilizer and what does it Mean
This is a common ratio of nutrients that gardeners like to use. It’s often described as “a complete fertilizer” because it contains all three macronutrients: nitrogen, phosphorous, and potassium. The numbers in the name refer to the amount of each nutrient within this mixture. This type of fertilizer would be used for plants that need an even application rate across all three macro-nutrients or if you’re looking for a more balanced approach than just using one kind on its own.
What is 7-2-4 Fertilizer Good for?
This type of fertilizer is good for most plants, especially those that need to be fertilized regularly. However, this mixture can’t keep up with the needs of very fast-growing or large trees like fruit and nut trees which require more than once per year application.
What it does: This kind of fertilizer provides a balance between giving your plants what they need in terms of nutrients while not over-fertilizing them (which would result in too much nitrogen) and under-fertilizing them (which might lead to stunted growth). It comes as either dry granules you sprinkle on top of the soil before planting or liquid concentrate diluted into the water prior to spraying onto leaves.
When to use it?
The best time to apply this kind of fertilizer is in the fall when you’re preparing your garden for winter. This gives it a chance to work its magic over the course of several months into the next season. You can also use an organic or chemical slow-release form if you prefer—just remember that these won’t provide as much quick nutrition during times of stress like drought or heavy pruning.
Applying 7-2-4 Fertilizer
If you’re using liquid concentrate, apply it in a slow and steady stream with the spray nozzle set to mist.
With powdered fertilizer, sprinkle an even layer across the surface of soil that’s been tilled or loosened thoroughly. Make sure your garden is ready for moisture retention—either by watering first or letting the rain do the work for you before applying.
Fertilizer application rate: The right amount varies depending on how big and old the trees are, their natural ability to sustain themselves with nutrients from their environment (for example, some herbaceous plants have deep roots while others might not), and other factors including what type of soil they live in. In general, though, fertilizing a healthy, mature tree should be done every other year with a product containing at least three percent nitrogen and two percent potassium.
