If you have a vegetable garden, you ‘re probably already aware that if you want the largest, strongest harvest, you need the right fertilizer. The thing is, there are so many choices out there; choosing the right one isn’t easy.
We’ve put together this analysis of the best vegetable garden fertilizer to help you find out what to look for and how to make a decision. Plus, we included an analysis of ten of the best available items.
Vegetable Garden Fertiliser Options
The best thing you can do is test your soil before you determine which fertilizer is right for you and you know what sort of fertilizer you need. For other plants, you have to remember the NPK ratio but with a vegetable garden, there are many other aspects to consider.
A lot of other nutrients are needed in vegetable gardens to grow healthy and give you the best and most delicious vegetables. This is why it is so important to use a fertilizer that is specifically intended for vegetable gardens. There are usually two main forms to choose from: organic and synthetic.
Synthetic fertilizers contain ingredients that are man-made. Some contain nutrients which the plant immediately uses. Some are made for gradually releasing the nutrients over a longer period of time. Others using them in combination.
Pay attention to the NPK ratio when looking at synthetic fertilizers. This is the sum of potassium, phosphorus, and nitrogen. Some vegetables prefer a 10-10-10 or 20-20-20 balanced ratio but others, prefer leafy greens, only need nitrogen and others need more potassium.
One thing you should remember is what sort of fertilizer you want. In the most part, liquid fertilizer is short-acting. This is typically applied to the soil or waterline but it is possible to add certain formulas directly to the leaves. Some formulae are powders designed to be dissolved in water and used in the same manner.
Another alternative is fertilizer in granular form. This form is usually intended for extended-release. Nutrients are gradually released out of the granules. A single program lasts for four months or more for certain formulae.

When to Apply Fertilizer to Vegetable Garden?
Whether you just start a garden or are planning to replant, the best time to fertilize is in the spring. If you’ve done a soil test and know you need to make a lot of changes before planting is safe, start early so you can get the fertilizer deep down into the soil before you start.
If your soil is all right, fertilizing in the spring is always a smart idea so you don’t have to worry about having any extra time. It’s a good idea to use a general, all-purpose fertilizer before seeding. You might even want to try one which is a bit higher in nitrogen.
Typically, when your plants start growing faster you need to add more fertilizer. Around this time the plants are essentially ramping up production and using more of the nutrients available. It hinges on the plant when you need to think about this.
Some plants grow fast pretty early in the season, such as lettuce. In the other hand, in the middle of the summer, plants such as cabbage, corn, tomatoes, and potatoes grow the fastest. At this level, they would need an extra boost.
If you are using an extended-release fertilizer, it may suffice to last the entire season. Follow the instructions for the kit, and keep an eye on the plants to ensure that they are stable. The only way to be sure that your soil is good is to check it over the summer and make changes as needed.
What time of day to apply fertilizer depends on that too. You don’t have to think about it with an extended-release fertilizer. The fertilizer is already in the soil, just make sure that you water it properly and that you are good to go.
When you add the fertilizer directly to the leaves, do so at any time early in the morning or late in the day. When the sunlight is bright and strong, applying this form of fertilizer at the height of the day’s heat will burn the leaves and cause serious damage to the plant.
All that said, it’s best to follow the instructions provided with your fertilizer because each is a little different.
How Often Should You Fertilize a Vegetable Garden?
If you’re planning to plant different seasonal items, you’ll have to do some research year-round. After harvesting all at the end of the season, and before the field is too hard to till, apply a balanced slow-release fertilizer to the soil.
Work it gently to the top few inches and then cover the ground. For that, a thick mulch layer works well. It provides on-surface food for worms that keep the soil aerated. The slow-release fertilizer replenishes the nutrients used up by the plant in the summer through the winter.
As we have said, it’s time for the start of the growing season to add some balanced fertilizer in the spring. When you fertilized in the winter, this might not be important, but again, the only way to say for sure is to check the soil.
In summer again fertilize. If you do this it depends on what kind of vegetables you produce. If you are not planting until the summer, add a balanced fertilizer with the gradual release. Check the soil as required to ensure that you are getting it right.
When the summer is particularly hot or dry, your garden requires a little extra care. Soft, dry soil makes it more difficult for the plants to use the nutrients available, so you can need to add some magnesium.
Fall crops don’t need as much fertilization as they have a shorter growing season. You can add fertilizer for fast release every few weeks, as needed. And if you get a frost, stop fertilizing. Because of the cold weather, the plants would be tired, and too much fertilizer will kill them.
You should always follow the instructions included with your chosen fertilizer. Just once a season should slow-release fertilizers be applied whereas short-acting should be applied every few weeks. Every brand is a little different so make sure you use yours the right way.
Both plants need fertilizer but exceptional are vegetable gardens. Rapid growth draws something from the soil. You need to use the best vegetable garden fertilizer to grow healthy plants that produce an abundance of large, delicious veggies.
There are a variety of issues to remember. Do you prefer organic or synthetic? Short-acting or protracted release? Liquefied or granulated? There is plenty to choose from different products. Fortunately, the items we reviewed cover a wide variety of choices and are highly recommended to all.
