What To Look For In Vitamin For Plants

Lots of plants can survive without supplementing them. Just take a look at all the wild trees, flowers and plants around you. They get lots of food from oxygen, hydrogen and carbon – whether they are in the air or the water.

A bit of supplementation will make the difference though. Feeding your plants on a regular basis will guarantee larger and richer plants. At the same time, feeding plants is essential when moving them, as supplementation can help them survive the transplant.

Now, which vitamin is best for plants? What do you need to look for when buying plant food?

Vitamin B

Most plant foods and supplements are rich in vitamins. While you can find products specifically based on nothing but vitamins, most others also bring in a heavy amount of vitamins, along other nutrients. From all the options out there, it seems vitamin B is the most significant one, so lots of manufacturers use it as a main ingredient.

Studies analyzing the impact of vitamin B (especially B1) over plants are not necessarily conclusive. Some studies claim there are no connections, while others show differently. One thing is for sure. Based on thousands of ratings and reviews, it seems vitamin B stimulates the growth, but it also helps plants during transplants. For this reason, lots of brands implement it as a top ingredient.

Other vitamins

The same story applies to vitamins C and E – studies are not conclusive, but they are widely used and the wide majority of buyers claim on great benefits.

It seems vitamin C is helpful if you live in a polluted area – such as city centers and industrial areas. The vitamin will help the plant tolerate smog better, but it will also improve the photosynthesis. It seems vitamin C is a protective element against ozone. If you use it on fruit trees, fruits tend to be more nutritious.

On the other hand, vitamin E is not to be overlooked either. If you live in a relatively cold area, vitamin E will increase the resistance to cold temperatures. In the long run, your plants will become cold resistant, which is a plus for gardeners.

Value for money

Now that you know what kind of nutrients your plants need, you have to hunt value for money. Ideally, you should get plant food as a concentrate. Whether it is soluble in water or it comes as a liquid, you should be able to mix it with water to achieve the desired results. Simply put, a large bottle will give you months or maybe even years of regular uses.

Ease of use

The ideal plant food should be mixed with water and stirred. Simple as that. Assuming you have the best soil for plants, it will absorb everything within minutes only. Top brands come up with this type of product. However, you will also find plant food that requires lots of preparation and mixes. Some of them are time consuming, while others require making separate purchases too. Go with simplicity then – the mix should be ready to go within less than a minute.

Frequently Asked Questions

It is perfectly normal to come up with a few questions while trying to figure which vitamin is best for plants. Here are the most common concerns out there.

How often should I feed my plants?

The answer to this question depends on multiple factors. For instance, it depends on the plants you have. Some of them require feeding in the spring time, while others need food in the fall season or on a regular basis. Then, it depends on the product you use too. At this point, make sure you double check the instructions. Some products can be used once a week, while others require monthly uses.

What happens if I feed my plant too often?

While many of the vitamins and foods for plants are natural, they can become aggressive towards your plants if you overfeed them. For example, you risk killing your plants. Too many nutrients will burn plants – just like too much water does. Of course, it depends on what kind of plants you have, but remember – feeding your plants too often will not help them grow faster. Simply stick to the manufacturer’s instructions.

Can I overfeed plants?

Yes, but a little attention to the instructions will prevent you from doing so. If your plant has weak roots, they are vulnerable to all kinds of affections. Disease, heat or drought can cause significant problems. Sometimes, the excess of food and nutrients can also cause roots to suffer. Dead stems and leaves will end up on the ground, creating a thatch that prevents air and water from reaching roots. The same problems may occur if your plants have healthy roots too, so avoid overfeeding them.


As a short final conclusion, feeding plants is not as easy as feeding yourself, but it is not too complicated either. Which vitamin is best for plants then? Most experts agree on vitamin B, but more nutrients in a specifically formulated food will not harm your plants.

Make sure you stick to quality products from reputable brands. If they are around for years, they have a good reputation and their products have great ratings, chances are those products will work wonders on your plants too.

No matter what you buy, remember that different plants have different needs. Also, different products come with different requirements and application rules. Always check the instructions and follow them in the smallest details.
