When Is the Right Time to Fertilize Gardenias?

In general terms, you should apply the fertilizer for your gardenias in spring, summer, and fall, with a pause during winter. Being evergreen plants, your gardenias should grow properly if tended in the right way.

If you’re just about to plant your very first batch of gardenias, it would be smart to test your soil first. Depending on the results, you may need to alter your soil’s pH in order to provide your plants with the optimal growing conditions.

More experienced gardeners advise examining the soil pH at least once a month. If the value is higher than 4.5 and lower than 5.5, you’re all set. If not, you may need to do something about it. Gardenias love high acidity, so your soil has to have the necessary acidity level for it to thrive.

It would also be wise to check the pH value every few weeks after the application of the fertilizer. If the value is not in the prescribed parameters, you should reapply the fertilizer, but it’s always best to simply abide by the manufacturer’s instructions.

The acidity of the soil depends on various reasons: your general location, the position of your plants (how close to the road are they, etc.), this all can influence your soil’s pH. For instance, soil close to the road is more alkaline in nature, so it requires more frequent fertilization.

Water also has some impact on the overall pH value of your soil. There are subtle differences between water from the tap and the water from a hose, and then there’s rain, which can further alter the acidity of your soil.

That’s why you should check your soil’s pH value relatively frequently in order to keep tabs on it and make all the necessary adjustments whenever the pH level is above or under the prescribed level.

How to Properly Fertilize Gardenias

How to Properly Fertilize Gardenias

There are several ways of fertilizing your gardenias depending on the sort of fertilizer you use. We strongly suggest you duly follow the manufacturers’ instructions in order to avoid any potential issues stemming from overusing the fertilizer. That being said, here are some general pointers for you to follow.

Liquid Fertilizer

In the case of liquid fertilizers, following the instructions on the pack is the key. Some more experienced gardeners advise the use of only half of the prescribed dosage in case you’re using a strong fertilizer.

A common mistake of all novice gardeners is the overuse of the fertilizer, which can have devastating consequences for their plants. They can sometimes use more than one full dose of a strong fertilizer hoping that that way they’d boost their plants’ growth, but such actions only result in the death of the plant.

This is why testing your soil’s pH matters so much. Depending on the pH level, you may decide to use a weaker fertilizer or half the dosage of a stronger one. This makes it much easier to choose the proper fertilizer which best suits your gardening needs.

Liquid fertilizers can be applied in more ways than one.

For example, if your goal is to cover a large surface as efficiently and as quickly as possible, the sprayer is the way to go. If you have a small garden or if you only keep potted plants, a common watering can or any other container will serve you well. Choose a container large enough for you to safely mix the fertilizer.

Bear in mind: some liquid fertilizers can be safely applied on both the foliage and the base of your gardenias, while others are meant for root-only application, so please follow the instructions to avoid the consequences of misapplication!

As for the number of times you need to use the fertilizer, it depends on the soil pH and the strength of the fertilizer itself. Usually, once or twice a month should do the trick, but in cases of pH not being in the prescribed range, another dose of the fertilizer may be necessary.

This may seem a bit intimidating for beginner gardeners, but don’t worry; just follow the instructions and all will be well!

Granular Fertilizers

Granular fertilizers are fertilizers specifically designed to work for long periods of time. These slow-releasing fertilizers have a special slowly-deteriorating coating which releases a stable dose of necessary nutrients into the soil until it completely dissolves.

The application of the granulated fertilizers varies. Generally speaking, if your plants are still young, the smartest thing to do is to insert the granules into the soil and then water it for optimal results.

In the case of older, stronger plants, spread the granules at the base of your plants and then water them. Watering after scattering the granules is essential. They are not designed to be dissolved in water before use!

Spike Fertilizers

Just like granules, spike-type fertilizers are also designed to be used for long periods of time and are probably the easiest form of fertilizers to use. All you need to do is to insert them into the soil as close to the roots as possible, and the water the soil generously so the nutrients can be released from the spikes.

All slow-working fertilizers are usually quite strong and full of nutrients necessary for the health of your gardenias, and they make your job much easier since they don’t need to be used as often as some other fertilizers!

Possible Fertilizing Issues

Gardenias require very specific conditions to grow healthy and beautiful, so if something goes wrong, it’s not that easy to discern if the fertilizer issues are to blame. Regularly testing the pH of the soil is the only way to know for sure whether the problem is in the fertilizer or in the soil itself.

Plants can suffer from various issues directly caused by the lack of necessary nutrients, but fertilizers aren’t always to blame for these problems.

Some types of insects can have quite a damaging influence on your plants. For example, the larvae of the black-vine weevil burrow deep among the roots of your plants and tear them apart in the process.

This stunts the growth of the gardenias due to the roots being unable to fully absorb all the nutrients required for them to grow into lush, beautiful flowers.

The salinity of the soil also plays a major role in the welfare of your plants. If the salinity levels of the soil are high, the reasons for that might be either you overusing your fertilizer or the very nature of the soil itself. High salinity levels of your soil do not benefit your gardenias at all.

Gardenias prefer the soil they grow from to be properly wet, but they won’t be able to properly develop if you overdo it with the watering. If the soil is too wet, the leaves will go from green to yellow and start falling off. If the soil is too dry, the leaves will turn brown, as if they’re burnt under the strong sun.

Determining the right reason for your gardenias not growing to their full potential is not always an easy thing to do, so the only way to know for sure if the problem is the lack of fertilizer, or overabundance of fertilizer, or something else entirely is to have your soil examined.

The Best Fertilizer for Gardenias (in General) + our top Choice

As we’ve mentioned earlier, gardenias are acid-loving plants, so the best fertilizers for them are those specifically designed to nurture acid-loving plants, and also be easily dissolvable in water. They are known as the acid fertilizers.

When the acidity level of the soil higher than 4.5 but lower than 5.5 in ideal conditions, the acid-loving plants will gain all the natural substances they need to thrive and grow.

Many acid fertilizers, as we have seen, lower the pH of the soil. That way, acid-loving plants gain all necessary nutrients they otherwise can’t get in the high-pH soil. Along with the acidity levels, they lower the soil temperature as well, which further benefits the plants such as your gardenias.

In order to retain these beneficial effects, fertilizers should be used roughly every two weeks, depending on the strength of the fertilizer, its form, and the prescribed instructions.

For safety reasons, when applying these fertilizers, always wear protective gear such as glasses, gloves, and long-sleeved clothing. Some of the chemicals may be harmful to humans, so try to avoid them getting in touch with your skin however you can.

Once you’re done with the application of your chosen fertilizer, make sure to thoroughly wash your hands with insecticidal soap.

Depending on your preferences and working conditions, it’s best if you use organic acid fertilizers since they lack the synthetic substances that can harm humans, and are generally easier to dissolve and absorb into the soil.

You can even make your own organic fertilizer! You will need:

  1. A cup of compost tea;
  2. One ounce of molasses, white vinegar, liquid seaweed;
  3. And just combine all that with one gallon of water.

All these ingredients are relatively easy to acquire, and the mixture should give excellent results. And if you don’t want to bother with mixing your own fertilizer, don’t worry: any of the fertilizers we listed earlier will be more than effective.

However, our personal recommendation would Jobe’s Organics (08281), due to its many beneficial effects and the overall safety and ease of use!


Gardenias need very specific conditions in order to thrive. You should pay attention to the pH and the salinity levels of the soil you use carefully chose the appropriate fertilizer, and apply it accordingly.

If you’re just starting to explore the magic of gardening, this may seem a bit intimidating, but it’s really not! If you test your soil regularly and follow the manufacturers’ instructions when applying the fertilizer, everything should be ok.

Just remember this: gardenias do need your love and care, but do not exaggerate – too much fertilizer is murder by kindness!
