Types of Products

Granules, liquid, and spikes are the three fundamental types of fertilizer. Each type of them is available in both organic or inorganic (synthetic) formulas.

Granular Fertilizers

Granular fertilizers are dry. Granular fertilizers can be spread with a spreader or shaken with the built-in shaker top on some canisters. You can easily see and control how much and where you're applying. Many dry fertilizer formulae are water soluble and can be diluted with a watering can, making fertilizing and watering your garden at the same time simple. Granular fertilizers are divided into two categories.

  • Slow-release fertilizer delivers a consistent delivery of nutrients over a long period of time, minimizing the need for frequent application.

  • Quick-release fertilizer provides nitrogen to plants almost instantly, but it must be applied frequently. Because it might injure plants if applied incorrectly, this fertilizer isn't suited for general plant maintenance. It can be used to remedy certain deficiencies.

Liquid Fertilizers

Most liquid fertilizers are applied with a canister and hose after being diluted with water. Gardeners can also use a watering can to manually mix liquid formulations with water. Liquid fertilizer is simple to use and absorbs swiftly through the leaves and roots, making nutrients available to plants immediately. This form of fertilizer must be used on a regular basis. The disadvantage is that it washes away easily in the rain and can contaminate surrounding water sources.

Fertilizer Spikes

It's quick and simple to utilize compressed fertilizer in the form of spikes that you stick in the ground. This type of fertilizer delivers nutrients gradually over time. Because the spikes do not require dilution or precise measurement, they are a perfect choice for the inexperienced gardener or those who are busy.

Organic vs. Synthetic Fertilizers

Organic and inorganic fertilizers differ primarily in two ways: components and how nutrients are made available to the plant.

  • Organic fertilizers supply essential organic matter to the soil and feed plants by collaborating with the soil's biological microbes. Composted chicken manure, bone meal, blood meal, and cottonseed meal are examples of plant and animal-based fertilizers.

  • Synthetic fertilizers are highly concentrated and provide direct nutrition to plants. Inorganic fertilizers are made from synthesized nitrogen, phosphorus, and potassium compounds, which are occasionally byproducts of other industrial operations.

Buying Guides

N-P-K Ratios

Before applying fertilizer to your garden soil, it's advisable to start with a soil test to determine its natural fertility. The results will reveal the nutrients your soil may be deficient in, allowing you to supplement them with proper fertilizer.

Nitrogen (N), phosphorus (P), and potassium (K) are the main nutrients in fertilizer. These ingredients are listed as a ratio on fertilizer bags, such as 1-1-1, 1-2-1 or 4-3-4. N-P-K is the order in which the packages are listed. The proper ratio for your garden is determined by what your plants require.

  • Nitrogen promotes the growth of vegetation. A high-nitrogen fertilizer can encourage the growth of grass in the spring or the production of a large supply of collard greens.

  • Phosphorus supports root growth, fruiting, and flowering. The use of a high-phosphorus fertilizer as a starting fertilizer or to brighten up annual flower beds is beneficial.

  • Potassium is necessary for the rigidity of stems and the overall health of plants. Potassium strengthens plants against disease, drought and other environmental challenges.

Plants' Needs

Plants of diverse types and development stages have different nutritional requirements. Are you starting from scratch with a new flower, veggie, or herb garden? To assist the young plants in developing themselves in their new environment, use a starter fertilizer. Do your azaleas, camellias, gardenias, or blueberries appear to be frail and underdeveloped? Give them a boost with a fertilizer made specifically for acid-loving plants. Plant food with a higher phosphorus concentration is required for flowering and fruiting plants, whereas plant food with a higher nitrogen content is required for foliage plants.

Fertilizer Quantity

Fertilizer applications on a regular basis maintain plants healthy and productive.  The frequency with which you apply fertilizer is determined by the type of soil you have and whether your plants are on raised beds or containers. During the growing season, most plants growing in porous, well-drained soil or in containers require more regular feeding, usually every three to four weeks. Plants that flourish on clay soil require less fertilizer. After planting, one application every four to six weeks is sufficient

Seasonal Use

The secret to growing a lush, healthy garden is to apply fertilizer at the correct time. Fertilizer applied at the inappropriate time is a waste of effort and money because the nutrients will be blown or washed away easily. It's critical to read the product label attentively and apply fertilizer at the recommended time.
