In this guide, we'll discuss water-soluble fertilizers' role, the benefits of liquid fertilizers, how to make fertilization more effective, and how frequently you should be fertilizing your lawn.
Before diving into the benefits of water-soluble fertilizers, it's first essential to understand what it means. Any ingredient or product that is water-soluble means that it can dissolve in and be absorbed by water. Water solubility measures how much of a given ingredient can be effectively dissolved and absorbed.
The excellent news for lawn fertilizers is that both granular and liquid fertilizers are water-soluble, though they may require different steps before or after lawn application. Finding the right water-soluble fertilizer for your lawn can bring you quick results with almost no fuss, depending on your grass care needs.
Lawn fertilizers are meant to be water-soluble so that the soil can adequately absorb them. When you're fertilizing your lawn, water solubility is crucial in whether your lawn care application is effective or not. The solubility of lawn fertilizers, granular or liquid, provides the grass with these benefits:
We can revitalize and rejuvenate lawns through an independent fertilization process because of the water-soluble properties of lawn fertilizers. Without this property, lawn fertilizers would sit at the surface of grass, rendering them ineffective without proper soil absorption and nutrient uptake.
Liquid fertilizers exist in a readily available form for fast nutrient absorption by the soil. Because of this fertilizer's liquid state, it has enhanced water solubility upon application. You can rest assured that the ingredients are getting to work fast. Liquid fertilizer allows for a more uniform application than granular fertilizer. Best of all, there is no heavy spreading equipment needed with liquid fertilizers—use your existing garden hose to apply this product with the bottle's spray nozzle.
There are even more benefits to going liquid with your lawn care. Liquid fertilizers are homogenous and well-mixed, so your lawn will get an even application; you will see consistent results in your yard. The water solubility in liquid fertilizer is even better due to the small particle sizes that allow for significant nutrient uptake by grassroots.
You can use your liquid fertilizer for more than just your grass. These water-soluble fertilizers can be sprayed onto plant foliage for an extra nutrient boost, too.
The physical application of lawn fertilization is not adequate alone. The water solubility of necessary macronutrients and micronutrients makes lawn fertilization useful. No matter which type of fertilizer you choose for your lawn care, these are steps you can take to ensure the effectiveness of your water-soluble fertilizers:
Researching ingredients in fertilizers will be the first step to ensuring sufficient water solubility. With these tips, you can get the most out of your water-soluble fertilizer. You might be asking yourself how often you should be applying this to your lawn - let’s learn more.
Navigating a lawn care schedule, especially a fertilizing schedule, can sometimes prove to be challenging. The factors contributing to lawn fertilization frequency may include grass type, season, and overall grass health. Your warm-season or cool-season grass may have different fertilization needs. Still, the general rule of thumb is to fertilize twice a year - once at the start of the growing season and again before the dormancy season (or the first frost if you are in a colder state.)
You do not need to adhere to fertilizing just twice a year rigidly. Instead, pay attention to what your lawn is telling you. Brown or yellowing leaves, dry patches, and an excess of weeds can tell you what you need to know about the state of your grass's health. The most conclusive way to tell if it's time for fertilization is to conduct a soil test. The results of the soil test will let you know of any nutrient deficiencies or pH imbalances. From there, you can decide the best course of action for your grass health. Regardless of which type of product you use, highly water-soluble fertilizers will yield faster, more effective results.
If you need help getting started, this fertilizer schedule supplies a month-by-month lawn care guide for your specific needs.
Fertilizer application generally only happens a few times per year, whether you choose a granular fertilizer or opt for liquid fertilizer. Therefore, you want to be sure your fertilizer application is practical and useful. Here are some tips on how to make the most out of your lawn fertilizer:
Your lawn is sure to enhance curb appeal in no time!
It’s that time of year where some plants in your garden are really starting to take off, and some are just hanging back, lingering in early stages of growth, turning weird shades of yellow or purple. ‘What does it all mean??!!’ you may ask yourself. Well, here on the Garden Club blog we want to help you get to the bottom of these nutrient mysteries and help you grow big, tasty, healthy plants.
Most gardeners are familiar with the classic triad of NPK, or nitrogen, phosphorus and potassium. Today we’re going to break these down for you. I highly recommend that every gardener (especially those growing straight in the ground and those with big gardens) get their soil tested each spring. You can buy a cheap test at your local garden center that will give you a rough idea of what’s going on in your soil. On a bigger scale and at a higher cost, a great resource for this is A & L labs – they accept mail-ordered soil samples and provide great explanations to accompany the results.
Once you get your soil test results you’ll know where your soil-based strengths are, and where your soil is lacking. With that information, you can make a plan to add the necessary nutrients back into the soil in solid (think boxes of granulated fertilizer or 50 pound bags of powdered gypsum, etc) or liquid (spray-on fertilizer) form.
It’s important to note that the three numbers listed on bagged and boxed fertilizer containers refers to the percentage (by weight) of the three major nutrients required for healthy plant growth. They always in the same order: nitrogen-phosphorus-potassium (NPK). When in doubt, add a ‘balanced’ fertilizer to your garden – that is, one where these three numbers are pretty close to one another, such as 5-5-5.
If you know your soil is lacking in a particular nutrient, look for the number corresponding to this nutrient to be considerably higher than the other two. Before planting, you may wish to work some fertilizer deep in your soil in order to promote strong root growth – a ratio of around 3-20-20 would work quite well for this.
Additionally, early on in a plant’s life, it needs a lot of nitrogen in order to grow large – so look for the first number corresponding to nitrogen to be higher (16-6-4 is a common ratio for a nitrogen-rich fertilizer).

Later, when it’s time for your plants to flower, you can revert back to the 3-20-20 fertilizer in order to help this phase of growth.
All of these fertilizer options are available in completely organic varieties. Often made with components such as blood meal, bone meal, rock phosphate, kelp, and oyster shell flour, organic fertilizers are potent, effective and free of harsh chemicals. Ask your local garden supply store about organic options.
Let’s look at little bit more closely at these three macro-nutrients and what they do for your plants.
Nitrogen has earned its place at the head of the ‘NPK’ line due to its crucial importance to plant development and growth. Every protein in plants contains nitrogen, and it is involved in almost every process that plants undertake in their life cycle. Growing big leafy canopies and tall green stems are both processes that depend most strongly on nitrogen. We all remember from middle school science class that chlorophyll is responsible for the green pigment in plants and helps the plant carry out photosynthesis. Well, our buddy nitrogen is a key component of chlorophyll, too.
For geeky gardeners like us, deeming something ‘nitrogenous’ is the same as noting that it is green, leafy, soft and moist. (When building compost piles, this is often contrasted with ‘carbonaceous’ materials, which are brown and dry and take longer to break down).
Nitrogen is often especially important in the early phases of a plant’s growth while it’s beneficial for the plant to grow a big scaffolding before it sets fruit. At that point, nitrogen (or too much of it) can actually hinder the process of producing the part of the plant that you’re aiming to eat! For example, last year I was really proud of my low tunnel greenhouse-grown Padron peppers. They began to produce huge, tall plants – growth that I encouraged through a few applications of blood meal, which is very high in nitrogen. Well, low and behold, come September I had shoulder high pepper plants, in a beautiful deep green, with hardly any peppers on them. I had overdone the nitrogen, which delayed and in fact prohibited the plant in switching over from its vegetative stage (producing new green growth) to its reproductive phase (when it grows fruit that will eventually produce seed). Oops.
When plants need it: Throughout their lives but especially early on in their growth- from planting until flowering. Compost and cover crops are great sources of slow-release nitrogen, which will always benefit a plant. But the quick-release form of nitrogen found in fertilizers should only be applied up until a plant is ready to flower.
How to tell if you’re lacking in it: A yellow color where there should be green, a small fruit yield, and/or small, stunted plants. Too much nitrogen, or too much too late in a plant’s cycle, can lead to large plants with delayed reproductive phases – that is, late flowering.
How best to add it: Compost and organic matter is rich in nitrogen, as is fish and kelp solutions, compost tea, and manure.
Also a crucial player in a plant’s photosynthesis, phosphorus helps a plant to develop its sugars, starches, and oils. It helps to make sweet fruit sweet and is a key player in helping plants produce seeds and synthesize protein. It also aids in a plant’s immune system – a plant rich in phosphorus is better able to withstand environmental stresses than a phosphorus-deficient plant. While nitrogen helps a plant grow big healthy leaves, phosphorus helps a plant grow strong roots and then helps to encourage blooming once flower formation has occurred.
When plants need it: Best to add it at planting time or a few days before.
How to tell if you’re lacking in it: Healthy looking fruit that is surprisingly unsweet may be due to a lack of phosphorus. Additionally, stunted plants, small fruit and flower yields, and odd and weak-looking flowers can be signs of phosphorus deficiencies. Too much phosphorus will inhibit a plant’s uptake of zinc as well as other nutrients, meaning that if your soil test indicated that you should amend with high levels of phosphorus, you should make sure to balance other related nutrients as well.
How best to add it: Bone meal is a great powdered form of a quick phosphorus boost.
Potassium plays an important role in helping plants store, harness, and regulate their energy. Additionally, water pressure within plant cells is regulated with the help of potassium. Throughout a plant’s life it needs to develop the capacity to store and utilize energy and water in order to help it withstand stress (derived from heat or cold, poor soil conditions, improper handling by impatient gardeners, or munching from critters). Potassium in all of its functions aids plants in their ability to respond to and overcome this stress. Potassium is proving to be an important player for me at my cut flower farm – as long, rigid stems require adequate amounts of potassium.
When plants need it: Throughout their lives, but adding before planting time is a good idea.
How to tell if you’re lacking in it: Low yields and deformed leaves (curled, spotted, weak, or scorched) are telltale signs of potassium deficiencies. Conversely, if a plant has too much potassium, it may look big and beautiful but actually be quite weak structurally.
How best to add it: Potassium sulfate or greensand are common products to use that can be worked right in to garden soils before planting.
I would be remiss to not give special shoutouts to two other leading ladies: calcium and magnesium. Calcium is another nutrient that helps plants develop strength, yet it also is of importance in helping plants absorb and use all of these other nutrients. A soil rich in one nutrient yet lacking in calcium may grow plants with clear deficiencies in spite of perfectly adequate levels of the macronutrients. Additionally, it helps soils to be more workable. Heavy clay soils often call for additional sources of calcium – often gypsum is recommended.
Magnesium is another key micronutrient that helps plants to activate a whole host of other nutrients. Plant enzymes require magnesium in order to produce carbohydrates and sugars. Additionally, healthy seeds, flowers and fruits require adequate levels of magnesium.
