Making your own fertilizer allows you to modify it to meet the individual requirements of your plants, which is one of its key advantages. For example, if your plant demands more acidic soil, you can use coffee grounds or white vinegar as a fertilizer foundation. Use eggshells or bone meal if your plant requires more calcium.

Another advantage of making your own fertilizer is that it is typically gentler on your plants and the environment than store-bought fertilizers. Many commercial fertilizers come with strong chemicals that can harm soil’s beneficial microbes and cause waterways to become contaminated.

How to Make Natural Fertilizer

You can use various ingredients to create fertilizer at home, but you want to be sure your plants receive the nutrients they require to develop. The main components of every fertilizer are nitrogen, phosphorus, and potassium, but calcium-rich substances are also beneficial for your plants. It’s advisable to conduct a soil test so you can decide what is most important.

This will enable you to determine your soil’s pH and the appropriate amendments. For instance, if you’re planting a plant that prefers acidic soil, you might want to utilize leftovers in your fertilizer that will lower the pH of your soil (like citrus peels).

Flowering Plants Fertilizer Schedule

Before planting, work the fertilizer into freshly created flowerbeds 4 to 6 inches above the earth. For the established plantation, evenly distribute the fertilizer around the plants, lightly rake it into the soil, and then thoroughly water the plants. Pull the mulch back around the plants so the fertilizer is applied to the soil rather than the mulch.

Spring Flowering Bulbs

Do not apply bone meal or other phosphorus sources until soil testing reveals they are required. As soon as fresh growth appears in the spring, fertilize the area. When preparing flowering beds in late August or early September, apply fertilizer at the same rate.

Summer Flowering Bulbs

Apply fertilizer at the time of planting or when growth starts up again in the spring in the form of hard summer flowering bulbs. If your plant has a short flowering period, apply a second application at the same rate after flowering.

Perennials, Ornamental Grasses (Established Plants)

When growth restarts in the spring, apply fertilizer. A second application at the same rate can benefit perennials with long blooming periods. 6–8 weeks after that.
