What Kind of Fertilizer is Best for Indoor Plants?

There are plenty of different kinds of fertilizers to pick from which is one explanation why choosing the best one for indoor plants can be so difficult. Here are a few different types:

Liquid Fertilizers

Typically, liquid fertilizers are applied to the irrigation any time you wash, or anytime. Any formulations may be used once or twice a month or feed the plants.

One of the great aspects of liquid fertilizer is how much is being added you have a lot of leverage. In stagnant times, you should avoid fertilizing and be sure there is no fertilizer already being released into the soil.

On the other hand, the drawback is that at the right moment you will have to apply nitrogen to the water which is better stated than done.

Granular Fertilizers

Fertilizer for Plant Application in Gardening

The soil is combined with granular fertilizers. When you’re first putting a plant, they perform particularly well and will spread the granules all over the pot.

Granules are a bit difficult to use on indoor plants and when the plant is drained they absorb all of their nutrients at once and it’s not straightforward to predict how many the plants need. Ignore the instructions on the box very closely so you don’t overfeed your plant or underfeed it.

Slow-Release Fertilizers

Slow-release fertilizers, including spikes, seeds, and pellets, come in several varieties. They have a time-release covering, which helps the nutrients to gradually penetrate the soil.

This form of fertilizer fits best in small containers as there’s less ground to protect, and you don’t have to think about the nutrient distribution too often.

One drawback to slow-release fertilizers is that there’s no way to tell how quickly the nutrients disperse. Ideally, the time-release shield always holds things a little so you never really learn.

When to Fertilize Indoor Plants?

How To Fertilize Indoor Plants for Beginners

When to fertilize outdoor plants is a little easy to figure out. Most come in the spring from dormancy and plan to grow flowers or fruits. A strong thumb rule is to fertilize to ready them for the spring and summer ahead, after the first freeze.

Yet they’re a bit different from house plants. Since they are not subjected to shifting sunshine and cold weather, whether to fertilize them is not always easy to learn. Here are a few tips and tricks for general.

  • While houseplants are not exposed to the elements, most of them are either dormant or semi-dormant in winter and require no fertilizer. Getting them fertilized at this time may lead to slow growth and render the plant vulnerable to disease and insects.
  • Any plant that continues to grow through the winter is an exception to this law. Every plant that develops vigorously should be fertilized, but use 1⁄2 or 1⁄4 in winter as much as you would in summer.
  • Plants that keep blooming in the winter should be fertilized using the normal number.
  • Start fertilizing indoor dormant or semi-dormant plants in late February. While being enclosed, houseplants often sense the shifting weather and can say spring is on its way.
  • Should not over-fertilize it if a plant is not performing good, because that will destroy the plant. Ensure sure it receives ample light and water so the surface will not get polluted.
  • Do not apply fertilizer to potting soil unless the manufacturer states that using it like that is healthy. Potting soil is also carrying nitrogen, so having so much excess may be dangerous.
  • If you are purchasing a plant from a home and garden center or greenhouse, find out when it was fertilized the last time. It may be detrimental to the plant to carry it home and apply more fertilizer, which is easily prevented.

How much do you fertilize plants indoors?

You will usually obey the instructions for the fertilizer that you are using and perform fertilizer applications as often as they suggest.

How much your indoor plants will be fertilized always depends on what kind of fertilizer you are using.

If you are using liquid fertilizer, you have some choices. Any formulae are meant to be added any time you drink. Others can be used for a bigger feed any other day, or once or twice a month.

That being said, some liquid fertilizers can be used in several ways, depending on how they are mixed together. Some brands inform you very specifically what fertilizer-water ratio you will use based on the form of application that you are using.

Granular fertilizers can be used as often as indicated by the kit. This will typically be implemented relatively regularly, about once every two weeks or so. Because granular fertilizers are quickly released into the soil, the soil is ready for more after the plant uses them up.

Spikes, pellets, and other slow-release fertilizers should be added as specified in the box. They will last for as long as two months or more, depending on how much you use and the plant size.

Once again, that depends on the form of fertilizer you use.

Read the directions closely for liquid fertilizers, so that you learn what dosage to use. You don’t normally need to use a number, maybe just a tablespoon or a spoonful. Use a liquid fertilizer that contains a measuring cup or spoon, or has one installed into the container if necessary. That helps to avoid mistakes.

Many liquid fertilizers are meant to be used directly at the surface. If so, remove the leaves the best you can, such that the majority of the fertilizer goes to the ground. Many liquid fertilizers may be added to the leaves directly. Use a spray bottle in this situation, and saturate the leaves well.

Granular fertilizers can be properly weighed and blended into the top 1 to 3 inches of soil. Know, granular fertilizers release their nutrients after watering pretty easily and you want to make sure the granules are sufficient for the whole plant.

This form of fertilizer can often be blended into the soil when a plant is repotted or transplanted. Again, this means not all fertilizers can be used, and make sure you follow the instructions for the goods that you are using.

Finally, slow-release fertilizers will be injected directly into the dirt, roughly halfway between the plant stem and the pot bottom, or as close to the waterline as you can come.

One of the problems with slow-release fertilizers is that they emit a concentrated volume of fertilizer across the injection region so this doesn’t automatically mean the nutrients go to all the roots.

To counter this, make sure you position the spikes around the plant equally, particularly if you have a big plant and several spikes or pods are being used. This even improves fertilizer delivery and can make the plant grow faster.

Final Thoughts

Finding good fertilizer for indoor plants isn’t always easy. There are too many popular labels to pick from, it may be tough to figure out which ones really operate.

One of the biggest aspects you need to bear in mind is to learn about your plants. Spend time researching your plant to learn more about when and how to fertilize it.  If you need help with that, check

If you’re searching for something you can submit for an overlook for a bit, go with a slow-release method you just need to submit a couple of times a year. What you need to do is drive them into the dirt, and protect them for weeks to months.

Check a liquid fertilizer if you want to get a lot of influence over how much fertilizer you are using. Because you can add them anytime you spray, you are granted specific control about how much fertilizer your plants are receiving and when it is being applied.

Finally, if you want a simple to use the product, go for granular fertilizer. There is no paste and no sticky mud, just brush it over, blend it in the top layers of the dirt, then drink as normal.
