How Long Does It Take To Make Granular Fertilizer Dissolve?

We understand how you feel when your garden is looking a little sadder than expected. Granular fertilizer is the rapid remedy you are looking for. This way, you do not have to wait for your fruits to ripen or your flowers to bloom for months. But if you are new to gardening in general, you might be wondering, how long does it take to make granular fertilizer dissolve? The answer lies in this article; let’s check it out!

Granular Fertilizer Dissolve

Most granular fertilizers are slow-release fertilizers

How Long Does Granular Fertilizer Take To Operate?

They can be accessible in a few days and persist for several weeks in the soil, depending on the product’s composition.

How long does it take for granular fertilizer to dissolve? Quick-release chemical composts typically take around 48 hours to show the results and last from 2 to 4 weeks. This type is best for enhancing the nitrogen level in the soil and obstructing the growth of weeds.

Slow-release composts are the most common granular formulae. They take longer to operate, about 2 weeks. Yet, they are more efficient since they release fewer nutrients at once. This type can last from 2 months to up to 9 months.

Organic nourishments take the longest to operate. To see the results, you will have to wait anywhere from 2 to 6 weeks. To compensate for the long releasing time, it offers the longest-lasting period in the soil, up to 10 years.

Why Do Organic Nourishments Take Longer Time To Work?

It is because organic nourishments frequently contain plant nutrients at low concentrations. These nutrients must be converted into inorganic forms by fungi and soil bacteria before houseplants can use them. This process slows their release, especially during the winter when soil microorganisms are less active.

Still, organic nourishments come with many advantages. They do not leave a crust on the soil like certain inorganic types. They also last longer and can continue to nourish your garden for months. Plus, they provide food for beneficial bacteria, making it simpler to work the soil.

What Time Of Day Should I Fertilize My Plants?

Fertilizing your plants usually corresponds to your watering schedule at specific periods of the year. You should apply compost in the early morning till 8 a.m. Since the sun is not shining during this time, both times are ideal.

You could take advantage of the cooler temperatures and fewer winds by fertilizing in the morning. Because the nutrients are well distributed throughout the topsoil and are watered without much evaporation, they reach the roots rapidly and activate absorption practically instantly. 

Never use compost during the day’s hottest hours, from late morning to afternoon. Plants can be stressed by daytime heat, making them more sensitive to nutrient absorption as they migrate down into the soil.

Comparison Between Granular Fertilizers?

Slow release is the most common form of granular fertilizers. This type of compost might be in the form of pellets or coarse powders that are supposed to break down slowly over each watering. Before you backfill your soil and plant, apply it to the planting hole according to the directions. 

You can also use it as a top dressing for already-established plants. However, the results will be less effective than pre-planted treatments. With each fresh planting, consider carefully before using granular fertilizers. For most crops, organic ones with a roughly balanced analysis would suffice.

Liquid type is more controllable, works faster, and can be utilized in a variety of ways throughout the season. You can apply them to the ground or the leaves.

Apply liquid fertilizer to the ground

Liquids can be broadcast, banded at planting, and utilized as a mid-season sidedress. Plant nutrients are absorbed by the leaves and are more readily available for plant use when foliar is sprayed rather than ground applied.

Foliar feeding is the fastest approach to feeding your plants. Since plants absorb moisture and nutrients via their leaves, foliar feedings can help your plants develop and produce more.

Liquid fertilizers can be applied and reapplied, diluted or combined for special feedings, and quantified in various ways. During the warmest, driest portions of summer, wait until the evening or later at night.

Suppose you want granular fertilizers’ nutritional advantages but want them to be instantly accessible to your grass. In that case, you may dissolve granular fertilizer in the water.

Although the overall amount of nutrients delivered by granular or liquid one for a given plant nutrition application is the same, there are certain differences:

  • Spatial: The distance between plant roots and fertilizer nutrients is referred to as spatial. Phosphorus, for example, is less mobile and can only go as near as the solitary granule carrying it. They are more mobile in the soil water solution when they are in liquid form.
  • Salt content: Granular composts can be “hot” because of their salt concentration. Roots can stay clear of a zone of grainy fertilizer with high nitrogen and potassium levels. For “starter,” liquids are frequently recommended.
  • Nutrient content: Each drop of liquid fertilizer has the same nutritional content, but granular ones have different nutrient components in each granule.

Here is a quick rundown of the benefits of both nourishment kinds.

  • Liquid fertilizer
    • Handling and application simplicity (once set up)
    • Easy blending
    • Application uniformity
    • Application as a starter and during the season
    • Can combine with crop protection chemicals
  • Granular fertilizer
    • Bulk pricing is less expensive
    • Easier to store (does not “settle” or “salt out” in cold weather)
    • Suitable for heavy pre-plant applications
    • Options for a gradual release (polymer-coated urea)

When To Use Fertilizer For The Best Results?

Spring brings with it longer days and milder temperatures. This is the weather your lawn craves after a long, cold winter. If you are not sure when to feed your greenery for the first time, you can use the temperature as a guide.

The temperature on the ground should ideally be approximately 55.4 degrees Fahrenheit. March through April is the greatest time to fertilize your grass, depending on where you reside. It is also preferable if you water your lawn a few days before applying the compost.

Water plants regularly when the soil is fertilized

Nourishments add extra nutrients to your lawn, preventing crabgrass and allowing it to grow green and thick. Begin placing the feed along the edge of your grass to ensure proper placement. After that, you may begin filling the center. 

Going back and forth in straight lines is similar to mowing your lawn. To finish the work, you should always use a lawn spreader rather than your hands.

How Often Should You Use Granular Fertilizer?

You might also question how often you need to fertilize, and the answer is that it depends on the type of compost you use. 

You can spread grainy fertilizers every six to eight weeks on average. Slow-release composts last for months, so a single application is usually sufficient for the entire growing season.

The amount of compost to apply and the frequency with which it should be applied are specified on the label. Soluble fertilizers, for example, are administered every two weeks.

Liquid fertilizers do not last very long. In most circumstances, they will only last one to two weeks in the soil.

Slow-release fertilizers, on the other hand, last approximately six to eight weeks. This compost will drain into the soil considerably faster due to its liquid nature. It is already flowing down to the subsoil and rock layers before you realize it.


Hopefully, you now have the answer to the question of how long it takes for the granular fertilizer to dissolve.

Fertilizing is always on the do-to list when it comes to taking care of your garden. Whether you use synthetic or organic ingredients, each approach has its own set of benefits and drawbacks.

Thus, choose carefully, and you will soon find a suitable fertilizer that meets all your demands.
