It’s the time of the year when you may be looking at your garden and wondering what to do to get it ready for spring. One thing you may need to do is fertilize it! Fertilizing your garden is important, but it can be tricky to know when and how to do it. In this blog post, we will discuss 28-0-3 fertilizer and how to use it in your garden!
What Does 28-0-3 Fertilizer Mean?
A fertilizer grade of 28-0-03 means that the product contains 28% nitrogen, 0% phosphate (P205), and 03% potash (K20). This type of fertilizer is also called a “high analysis” or “superphosphate.”
The three numbers on a bag of fertilizer represent the percentage by weight of each nutrient in the mix.
What is 28-0-3 Fertilizer Good for?
A 28-0-03 fertilizer is a granular synthetic formulation containing nitrogen, phosphorus, and potassium. A high amount of nitrogen promotes the quick greening up for plants in early spring or after winter dormancy. The plant’s leaves will get more vigorous growth upon application of this type of fertilizer. Phosphorus ensures root formation and water uptake while strengthening stems to withstand winds and heavy rains during storms as well as stress from dry spells with little rainfall. Potassium helps prevent disease by encouraging strong cell walls that keep out fungi attacks such as blight, mildew, and mold. It also supports photosynthesis for healthy chlorophyll production for dark green foliage coloration along with aiding water movement through the plant making it more tolerant to heat and drought.
On what plants can it be used?
You can use 28-0-03 fertilizer for a wide range of crops and plants.
This product is labeled for use in both vegetable gardens, flowers, and roses as well as bulbs such as tulips, daffodils, irises, or crocus. It also works well when applied with other fertilizers including organic options like composted manure tea.
Some of the best plants to use this on include: tomatoes, peppers, eggplant, and other fruiting vegetables (cucumbers, squash, etc.), roses, petunias, impatiens, lilies, and other flowering plants.
When to Apply Fertilizer 28-0-03?
The best time to fertilize with this product is in early spring before new growth begins and then again in late summer or early fall. For vegetable gardens and annual flowers, you can also side-dress (fertilize the soil around the plants) with a product like this every four to six weeks.
How to Use 28-0-03 Fertilizer?
There are many ways to use 28-0-03 fertilizer, but the most common is by scattering it over the ground before planting. You can also put it in trenches around your plants or mix it with water and pour it on the roots. If you’re using dry fertilizer, make sure to wet it down first so that the nutrients will be available to the plants.
Another way to fertilize using 28-0-03 is through foliar feeding. This means spraying the leaves of your plants with a diluted solution of the nutrient mixture. Be careful not to get any on the buds or flowers, as this could harm them. The best time of day to foliar feed is early in the morning or late in the evening when the sun is not very strong.
