Types of Houseplant Fertilizer

Fertilizers come in a range of different forms.  The most common are liquid, sticks or pods, tablets and granules.  Liquids and slow releasing tablets or granules are best for indoor plants as they provide a more sustained and reliable nutrient source.  Pods are great, but they break down at different rates depending on their placement so you have  little control over the fertilization of your plant.   Each fertilizer has a different purpose and fills a different need so keep reading to find out more.

Liquid Fertilizers

Liquid fertilizers are mixed with water to provide your plant with food and hydration. The rate at which your plant requires fertilizing will depend on its species.  The more tropical your plant or the larger its flower and bloom, the more your plant will require feeding, so make sure to check the guidelines of the specific plant you are fertilizing.  Liquid fertilizer is a great option to provide your plant with immediate and direct nutrition because it gets straight to the root to make these nutrients available to the plant. 

They are also easy to use in a range of different potting areas and can be paused when the plant is dormant.  The main drawback to these fertilizers is that you are responsible for sustainable provision of nutrients and you need to remember to use them every time or every other time.  The best way to make sure you remember is to create a feeding schedule for your plants.  If you are looking for a liquid fertilizer, the Plants for Pets Indoor Plant Food is a great option which is perfect for home use and a large range of plants.

Granular Fertilizers

Granular fertilizers are dry pellets which are mixed into the soil and activated when the plant is watered.  These fertilizers can be used both in and outdoors to make them more versatile.  However, their drawback is that they activate very quickly and don’t provide a sustainable food source to the plant.  You therefore need to remember to fertilize your plant regularly when using granules to make sure it gets everything it needs. 

Another drawback is that the granules are not readily available to the plant from the point of application, they require water to transport the fertilizer to the roots.  If you are looking for a granule option, the Joyful Dirt Organic Indoor House Plant Fertilizer is a great option as it can also be added to water for direct application and can be sprinkled as a granule to provide sustainable nutrients.  This means you can get your plant fertilized immediately then provide it with more fertilizer so that there is a constant source of food.

Slow Release Fertilizers

Slow release fertilizers are a firm favorite in the gardening world because they are low maintenance and very easy to use.  These fertilizers come in pod form and are coated in a shell which breaks down slowly to provide consistent nutrients over time.  Each pellet has a different rate of release, so make sure to check this when you purchase so that you get the best option for your plants needs. 

These pods are also odorless and don’t require mixing, so they are much more convenient for the busy gardener.  The main downside is that they are more expensive due to the way they are designed, however they tend to last much longer than other fertilizer options.  If this is the kind of fertilizer you are looking for, the EarthPods Organic Fertilizer Spikes are an eco friendly and sustainable fertilizer source which is perfect for home use both in and outdoors.


When You Should Feed Your Houseplants

Your houseplants will wilt and die if they don’t get what they need, but there are a number of signs you should be aware of so that you know when your plants need a little extra support.  Fertilization is a little trickier to know when it is needed, so we will help you with this, too.

Wilting

If your plant is starting to wilt then it needs water.  However, overwatering can be just as big of a risk if you’re not careful.  The best way to avoid these issues is to have a consistent watering schedule depending on the needs of your plant.  You can also buy a water dispenser which provides consistent a water source at all times, which is great for plants which are prone to drying out.

Pale, Lanky Leaves

If your plants are looking a little pale, they may not be getting enough sunlight.  Try moving your plant closer to a window without putting it in direct light.  This will allow your plant to get the vitamins it needs from the sun without being burned by the heat.

Crispy Leaves

If there is not enough humidity in the room, your plant may turn crispy.  There are some plants which require more humidity than others, so if your plant is showing signs of a lack of humidity, it may be more suited to a bathroom where there is a source of steam.

Rotting

If there is too much humidity in the room, your plant may begin to rot.  This can be dangerous as the damage that rot can do to a plant can happen very quickly.  It may require you to cut off the rotten parts and move the plant to a dryer part of the house.


So, when do I fertilize?

It can be difficult to know when exactly your plant needs fertilizer because there are no clear signs.  The best way to know when to feed your plants is to make a schedule according to the plant’s needs.  Each different species of plant will need different things, so to make a schedule it is a good idea to do some research on when your plant needs food and how often.


The N-P-K Ratio

When looking at different kinds of fertilizer you may have seen a number that looks something like this: 10-5-10.  This is known as the N-P-K ration and it represents the information regarding the nutrient percentages in the fertilizer.  The number above will represent a fertilizer with 10% nitrogen, 5% phosphorus and 10% potassium.

N represents the nitrogen percentage.  Nitrogen is important to support healthy, vibrant leaves and is usually the higher number in the ratio.  P is the phosphorus percentage.  Phosphorus helps the plant to grow flowers as it develops, so is important in the early growing phase so that a larger bloom can take place when the plant flowers.  K is the potassium percentage.  Potassium helps to support the plant grow fruits.  This is less important with indoor plants where fruits are not produced, but is vital if you are looking for a fertilizer for fruit or vegetable bearing plants.

Fertilizers will have at least one of these nutrients but not necessarily all.  If you are not looking to produce fruit, the potassium level will most likely be 0.  To get the best fertilizer for your plants, do a little research into the best ratio for the plant you are buying for and at which stage of growth it is in to make sure you get the right option.


Houseplant Fertilizer Schedule

The key to a successful grow is to fertilize at the right times.  Different plants will need different levels of fertilization throughout the year depending on the growing season and when the plants are in bloom.  We at Surf’n’Buy have created a basic indoor houseplant fertilizer schedule to help you create one specifically designed for your houseplants.

Spring Houseplant Fertilizing Schedule

For spring houseplants, you should start fertilizing around eight weeks before the last expected spring frost.  If you don’t know when this is, you can look it up on the internet for an estimated date, then simply work back from there.  The first three fertilizer applications should be made at about half of the recommended strength on the container because they aren’t in the growth stages just yet and therefore don’t require a full dose.  Simply fertilize at the recommended time periods on the container, but at half strength for the first three before using a full dose at application number four.

Summer Houseplant Fertilizing Schedule

As summer starts to role around, your plants will need more regular fertilization.  Follow the instructions on your container to the letter at this point, as the type of fertilizer you are using will make a big difference.  Liquid fertilizers will need much more frequent application than granules or pods, so make sure to jot down when you fertilize and when you need to again.  These instructions should be followed regardless of whether you move the plants outdoors for the summer because they are still in the blooming stages and need constant support to be able to handle changes in temperature and exposure to the elements.

Fall Houseplant Fertilizing Schedule

At around eight weeks before the first expected frost of fall, begin to slow your fertilization applications.  Start by using half doses and then begin to double the amount of time between applications to get your plants ready for winter. 

Winter Houseplant Fertilizing Schedule

Your plants aren’t in an active growth phase in winder so you do not need to fertilize them at all.  Doing so won’t do the plant any good and can actually cause it damage as you may burn the leaves.  This happens because the plant is not actively taking in any of the nutrients and their presence in the soil can cause the plant damage.


Conclusion

Indoor plants are a joy to behold.  They can really tie together a room and bring a peaceful and happy atmosphere to the home.  However, it is important to keep them healthy and happy so that they look their best and so does your home.  Fertilizing your plants provides them with everything they need for a successful growth and keeps your plants looking their best.

Depending on the needs of your plant, as well as your own schedule, you might require different kinds of fertilizer.  That is why Surf’n’Buy felt it was important to bring you a wide range of fertilizer types with the Plants for Pets Indoor Plant Food, Joyful Dirt Organic Indoor House Plant Fertilizer and EarthPods Organic Fertilizer Spikes.  These fertilizers offer different levels of fertilizer as well as allowing you to customize your fertilization schedule to the needs of your plants and your availability to apply it.  These fertilizers are all powerful in their own right, but we are confident that one of them will suit each plant owner best.
