What is Fertilizer?
Fertilizer is a substance used in gardening that contains several chemical and mineral elements that promote growth and good health for plants.
Fertilizer can be made of natural or artificial ingredients, be organic or inorganic, and sometimes both, and it’s used in all types of gardening from potted plants to larger garden beds.
A fertilizer’s job is to enhance the health of the soil and add nutrients that the plants feed on. These nutrients might naturally occur in the ground, but because of previous crops or external factors, they’re lost and need replenishing.
Fertilizer is added to the soil of a garden usually, and it comes in a few different types including liquids and solids.
Depending on what you’re growing and the type of product you use, a fertilizer may need to be applied as often as weekly or could be left every few months before needing application.
The Importance of Fertilizing Your Vegetable Garden
When you plant a seed or a mature plant, the soil is responsible for providing it with its nutrients. Although water and sunlight play large roles in helping a plant to grow, without these nutrients, it’ll fail to thrive.
This is especially true when growing vegetables as they require a unique mix of minerals and chemicals to grow well.
A vegetable garden requires a unique type of fertilizer, and you’ll come to learn more about them as your gardening skills progress.
Most fertilizer products feature a fertilizer analysis that shows the percentage of nitrogen, phosphorus, and potassium that it features, and all three of these are essential to growing vegetables but in varying amounts.
Regular application of fertilizer to the soil of your vegetable garden will get great results in the taste, color, size, and quantity of produce.
Just as important as the hours of sunlight a garden gets or how often it’s watered, fertilizer can mean the difference between thriving and dying plants.
Correct Timing of Fertilizer Application
With the right fertilizer in hand, you’ll then need to establish the correct timing of when to apply it.
This can vary quite a bit depending on the product, the season, what you’re growing, and a whole range of other factors, but once you get it right, it’s a schedule you should stick to like clockwork.
Before applying any fertilizer, have a look at your garden to see what it’s telling you.
A vegetable garden in need of fertilization will be yellow or may have been slow growing. If the plants seem vibrant and the leaves are green, there’s no need to rush into starting fertilizers just yet.
A vegetable garden with adequately draining soil needs to be fed more frequently than clay or less porous soil.
With an assessment of your garden and its soil, you’ll be able to figure out where yours is and get a good idea of what’s recommended from the manufacturer of the fertilizer you’re using.
For well-draining soils, apply the fertilizer every three to four weeks during growing seasons, which could be year-round depending on where you live.
Vegetables planted in clay soils only need to be fertilized every five to six weeks as this type of soil is better at holding it in.
Never attempt to fertilize when it doesn’t seem necessary as too much can burn a plant, and especially vegetables which can be sensitive.
The Methods for Applying Fertilizer
Vegetables have unique needs compared to other plants and this includes the way the fertilizer is applied. You’ll also have to consider the nutrients, soil condition, and your preferences as a gardener to determine which of these is best for fertilizer application.
The broadcasting method is most commonly used with pellets, granules, or bulk amounts of clumping fertilizer. It can be spread by hand or using a drop or hand-held device with a crank.
You can either broadcast the fertilizer on top of the soil and then mix it through or onto growing plants and topsoil to then be watered and spread.
A deep soil fertilizer is one mixed deep into the ground, usually using a rototiller or similar tool.
By mixing the fertilizer deeper down it ensures the entirety is covered and then you can work more into the soil at the top so that it’s spread everywhere.
This method is best achieved with organic manures like manure and compost.
Liquid fertilizer is a preferred method for some gardeners as it’s easy to do and doesn’t require any digging.
A water-soluble fertilizer is placed in a spray bottle and applied to the leaves so the soil can’t transfer the nutrients on its own, and then applied to the ground through irrigation.
However, you must be careful to only use a vegetable-friendly fertilizer as others can burn the sensitive leaves.
This method is used when you have multiple rows of vegetables and is usually best at the earlier stages of growth like when you have seeds.
The fertilizer should be placed two inches to the side of the seed and two inches below it in the soil.
You will be placing a band of fertilizer on each side of the seed furrow so that it penetrates it entirely.
Fertilize Your Garden to Greatness
Any good gardener knows the worth of fertilizer and this couldn’t be truer than when growing vegetables.
After spending some time assessing your garden and its needs, you should be able to come up with the perfect products to suit your budding vegetables, whether it’s organic, inorganic, or otherwise.
The good news about fertilizer is that there’s something out there for every purpose and you can easily buy ready-made options perfect for the needs of vegetables.
All you have to do is commit to the application and you’ll see results within weeks of brighter, more colorful, and tastier products direct from your garden to your kitchen table.
Fertilizer is a gardener’s best friend but it’s not always as easy as picking one up off the shelves and throwing it into the soil for the best results.
Gardening vegetables can be especially finicky and there’s a lot more to learn to get it right.
For those new to gardening or still unsure about how a good fertilizer works, check out these commonly asked questions about it and our expert responses.
What Vegetables Need Lots of Nitrogen?
All vegetables require a unique combination of nitrogen, phosphorous, and potassium to thrive, and some need more nitrogen than others.
Vegetables that fall into this category include Asian greens, cabbage, cauliflower, spinach, leek, beets, and broccoli, so be mindful of the fertilizer you use if you have these in your garden.
Which Fertilizer is High in Nitrogen?
If you need a fertilizer with higher nitrogen content, you can search for one that features organic materials, and most specifically, urea.
Urea can be sourced from organic matter like urine, blood, and features, all of which have high levels of nitrogen and are commonly found in fertilizers, so consider adding these to your vegetable patch for the best results.
What Are Some Natural Fertilizers?
Some people prefer to only use natural ingredients for their gardens but these might not always be as effective as ready-made products when growing vegetables.
However, if you want to try a natural approach the most powerful natural alternatives include lime, kelp, cow manure, home compost, and limestone.
