Using a watering can, liquid fertilizers are applied after being diluted in water. You might fertilize every time you water or every other time, depending on the label’s directions. The frequency will also depend on the type of plant, since some, particularly those with showy huge blooms, may need more regular feeding. Always do your research on the nutritional requirements of plants to understand what they require. You can carefully manage the amount of nutrients that are continuously supplied by liquid fertilizer. For instance, it is simple to stop feeding the plant during the winter months when it is dormant and to start feeding more when it begins to sprout new growth. The drawback is that you have to remember to do it each time.
How should I feed my indoor plants?
Because organic fertilizers strengthen the soil over time and help it contain more nutrients and water, many gardeners favor them over chemical fertilizers. Manure, plant waste (compost), animal waste (compost), or mineral powders like bone meal are the most common sources of organic fertilizers. Even though they may have had minimal processing, they are occasionally referred to as “natural.”
Move your houseplant to a larger pot if it isn’t growing or if roots are erupting from the bottom of the pot. To promote new growth, use a liquid fertilizer and organic potting soil.
Do my indoor plants really need to be fertilized?
You are aware that indoor plants require water and sunlight, but what about fertilizer? Fertilizing indoor plants during the growing season can provide them the nitrogen (N), phosphorus (P), and potassium (K) they require to thrive (K).
Similar to learning how to repot a plant, feeding your houseplants can seem intimidating at first. However, after you master the fundamentals, you’ll wonder how your plants ever survived without it. The numerous types of fertilizer available, what fertilizer is (hint: it’s not plant food), and how and when to fertilize houseplants are all covered in the sections below.
What is fertilizer?
First and foremost, plants do not eat fertilizer. Photosynthesis is the process through which plants produce their sustenance while utilizing sunlight. Fertilizer promotes fresh, healthy growth in a similar manner to a multivitamin. Additionally, it can be utilized to replenish the vital minerals that our plants’ potting soil loses as they mature. The main ingredients, or macronutrients, in fertilizers are nitrogen (N), phosphorus (P), and potassium (K), which we will discuss in more detail later. Fertilizers can also contain a variety of other nutrients.
When should I fertilize my houseplants?
like excessive amounts of light or water Your plants may suffer if you use too much fertilizer. During the growing season, which runs from early spring to late summer, we advise fertilizing indoor plants moderately. Plants will gain the most from new nutrients at this period, while they are actively growing. Depending on the fertilizer you’re using, you can typically fertilize your plants monthly or every other week. Read the label carefully because each brand may have a different suggestion for dilution and timing.
Fertilizer will not help newly potted or repotted plants. They haven’t even begun to use all the nutrients in their fresh potting mix! Wait 23 months after a fresh repotting before fertilizing actively growing plants during the growing season to prevent potentially harming recently replanted plants. You can postpone fertilizing until the following growing season if you potted during the autumn and winter.
Because of their decreased metabolic activity, plants in low-light conditions don’t require fertilizer. They don’t consume nutrients as efficiently as individuals who are in brighter light.
What do the numbers on fertilizer mean?
Three of the approximately 17 necessary plant nutrients are prominently featured on the front of the majority of fertilizers. The N-P-K ratio is represented by the three numbers you see: N stands for nitrogen, P for phosphorus, and K for potassium. The main macronutrients that your plant requires are these.
A fertilizer label can include an N-P-K ratio that looks like 10-5-8. Higher ratio fertilizers are more concentrated than lower ratio fertilizers. Do not assume that a fertilizer with greater numbers is superior than one with fewer numbers just because it has higher numbers. It just needs more water to be diluted with because it is more concentrated.
Micronutrients could be included in your fertilizer, making it a complete fertilizer. These can contain things like chlorine, iron, manganese, zinc, copper, boron, and molybdenum. Each micronutrient plays a part in the cellular, enzymatic, and developmental processes of plants, but they are not as essential as the NPK macronutrients. Your fertilizer’s micronutrient content will probably be listed on the back of the container.
For your indoor plants, you can use any all-balanced fertilizer (for instance, 5-5-5) or one with a ratio that fits the goal you want to achieve. In order to stimulate leaf production, for instance, a fertilizer with a higher nitrogen to phosphorous ratio is best, whereas a higher phosphorous to nitrogen ratio aids in promoting fruiting and blooming.
Is solid or liquid fertilizer better?
There are various types of fertilizers. It is mainly a matter of preference when selecting the type of fertilizer to use. Both give the vital nutrients that plants require, yet they each have advantages and disadvantages.
The two types of fertilizers used most frequently for indoor plants are liquid and powder. They may also be the most economical depending on how concentrated they are, or how high their N-P-K ratio is. Fertilizers in liquid and powder form are also simple to use and diluted in water. You can also immediately add a variety of powder fertilizers to the potting soil.
Perhaps less frequently used for houseplants are solid fertilizers, sometimes known as dry or granular fertilizers. Because some granular fertilizers (fertilizer pellets) release nutrients over time, you run the risk of overfertilizing a plant or fertilizing it when it is dormant or growing slowly because of poor light.
Is chemical or organic fertilizer better?
Another option is selecting between synthetic fertilizers, commonly known as chemical fertilizers, and organic fertilizers. The macro and micro nutrients in synthetic fertilizers are typically more precisely balanced and concentrated. They might be more affordable, particularly if you buy them in liquid form to dilute. With less, you can obtain the same amount of nutrients.
Organic fertilizers are typically less concentrated because they are created from all-natural components, such as reprocessed food waste. However, mild is a benefit, not a drawback, of houseplant fertilizer. Although it can be slightly more expensive than other forms, organic fertilizer is a safe, chemical-free choice. Choosing an organic fertilizer may be the finest option if you have pets who share your space.
Chemical and organic fertilizers both supply nitrates, potassium ions, and phosphates to plants, but in different ways. It strikes a balance between your personal preferences and those of your plants.
Quick Tips for Fertilizing Houseplants
First tip: Since plants begin to actively grow in the spring, it is the optimal time to begin fertilizing them. Fast-growing plants should get fertilizer more frequently than slower-growing or dormant plants, such as cacti (i.e., most plants in winter.)
Second tip: Dilute your fertilizer. Less fertilization is preferable to more fertilization. If the potting mix is deficient in nutrients and you haven’t fertilized in about a year, you can improve the efficacy of the fertilizer by diluting it with less water.
3. Plants that produce fruits or flowers over their lifetimes will need extra fertilizer. Picking off fruits or flowers depletes them of their nutrients, which we should replenish.
Know your N, P, and K values. The ratio of macronutrients that should be present in your fertilizer is the one that your plant requires. It resembles the numbers 10-8-10. Find another fertilizer if this isn’t stated on the package.
5. Plants only require a smaller amount of micronutrients than they do of macronutrients, notwithstanding their importance. Micronutrients are typically present in fertilizers, however they aren’t usually highlighted on the front of the fertilizer container.
How frequently should you fertilize indoor plants?
When indoor plants are actively growing in the spring and summer, fertilize them. Use a fertilizer that is complete and contains potassium, phosphorus, and nitrogen. Fertilizers for indoor plants can be found in liquid, crystal, granular, spike, and tablet form. Depending on the product, application frequency might range from once every two weeks to once every three to four months. Read the directions on the label attentively.
During the winter, avoid fertilizing indoor plants. Winter is when most indoor plants do not grow vigorously and do not require fertilization.
Which fertilizer do you use to indoor plants?
The best fertilizer for indoor plants depends on the plants you cultivate. Typically, flowering plants require a greater phosphorus ratio. Non-flowering indoor plants, on the other hand, require more nitrogen for wholesome growth. A balanced plant fertilizer is the best choice for the majority of indoor plants.
For small potted blooming plants like African violets or begonias, 7-9-5 NPK is the best fertilizer. Other kinds of flowering houseplants, however, require a 1-3-1 ratio. Tropical indoor plants with green, leafy growth require a higher nitrogen ratio. Or a balanced indoor plant fertilizer like 5-5-3 or 5-5-5 would be great. A 20-20-20 fertilizer is one of the most popular all-purpose liquid plant meals.
For particular plant varieties, commercial potting mixtures are specially designed. Therefore, a potting medium for calatheas, hoyas, or peperomia would have a different ratio of nitrogen, phosphate, and potassium than a soil medium for cacti and succulents. Additionally, flowering plants need a different kind of fertilizer than indoor plants that never bloom.
Which plants ought to be fertilized sparingly?
Butterfly weed (Asclepias tuberosa), false indigo (Baptisia australis), asters, pinks (Dianthus spp.), rock roses (Helianthemum spp.), sea holly (Eryngium spp.), bee balm (Monarda didyma), speedwell (Veronica spp.), and coneflowers (Echinacea spp.) are perennial plants that thrive without

Why are indoor plant leaves yellowing?
To figure out why your favorite houseplant has suddenly started to produce yellow leaves, you don’t need to be Sherlock Holmes, but you will need to perform some investigation. This is due to the fact that yellow leaves might indicate a variety of conditions. Here are seven typical causes of yellow leaves in houseplants.
1. Water
Yellow leaves can be caused by either too much or too little water. Your plant may eventually sacrifice some of its foliage in an effort to conserve moisture if it is not given enough water. Conversely, too much water will frequently cause the death of your plant’s roots because they are unable to breathe in saturated soil. Yellow leaves will also grow on your plant as a result of this.
Start by making sure your plant is in a pot with drainage holes at the bottom if you want to avoid any of these issues. Between waterings, the extra water will be able to drain via these holes. When the top inch of soil seems dry to the touch, water your plants only then. From pot to pot, frequency may vary depending on factors like size (larger pots with more soil generally need less frequent watering), season (most plants don’t use much moisture during the dark days of winter), and plant type (succulents, for example, don’t need as much water as heavy drinkers like peace lilies).
2. Light
If houseplants receive too much or too little light, their leaves may also become yellow. If plants that prefer shade, such as tropical ferns, nerve plants, and calathea, are forced to dwell in a bright location, their leaves will gradually start to turn yellow.
Conversely, if cultivated in gloomy settings, sun-loving indoor plants like succulents, crotons, and jade plants may begin to yellow. When purchasing a new houseplant, always read the label and put it in a location that meets its light needs. Most types of houseplants will thrive in direct, bright light.
3. Delivery
It might not be a problem if your houseplant begins to drop yellow leaves as soon as you get it home from the garden center. Most likely, your plant is simply shedding leaves it can no longer support as it adjusts to the lower light levels in your home. Some species, like the ficus, for instance, will occasionally drop their yellow leaves when they are relocated. But don’t worry; usually, after a little period of adjusting, your plant will produce a new crop of foliage.
Repotting houseplants shouldn’t be done for at least a week or two after you get them home, to give them time to become used to their new surroundings and reduce transplant stress.
4. Resilience
Lower leaves on older plants frequently turn yellow and drop off. Your plant is not sick as a result of this. It simply means that the plant no longer requires those lower leaves because they are now shadowed by higher foliage. Additionally, keep in mind that many typical houseplants are actually trees in their original habitats, and that when they grow larger, they attempt to develop a trunk by shedding their leaves. For instance, Norfolk Island pines sometimes sacrifice their lower boughs as they get taller and taller.
Five. Hunger
If a houseplant lacks some essential nutrients in the soil, they will also grow yellow or splotchy leaves. Since plants are typically cultivated and marketed in nutrient-rich potting mix, this is typically not an issue when you initially purchase a plant (and most of our plants come with a time-release fertilizer added). To retain healthy leaves, however, your plants will eventually exhaust the food that they were given and require a little boost of plant food. Every time you water your plants, give them a small amount of diluted liquid fertilizer to keep them healthy.
6. Pests
Yellow leaves on your houseplants can also be caused by indoor plant pests like aphids and spider mites. Both suck plant juices, which makes the leaves appear aerated and fading. Aphids have tiny rice-grain-like attachments at the ends of their stems. Spider mites produce fine-hair-like webs on the undersides of the leaves of your plants, but they are nearly impossible to notice with the naked eye. An organic insecticide for houseplants can be used to control both pests. Maintain a high degree of humidity around your plants because these pests also thrive in dry air.
7. Thermometer
Because they are tropical plants, indoor plants don’t like harsh weather. Your plants may drop yellow leaves if they are forced to dwell too close to a heat vent, fireplace, air conditioner, or drafty window or door. Most houseplants grow in a range of 65 to 80 degrees Fahrenheit.
What occurs if indoor plants aren’t fertilized?
Recently, I’ve been asked a lot of questions regarding fertilizing houseplants. All of my correspondents appear to be of the opinion that fertilization is crucial to the survival of their plants. However, that is not at all the case. In actuality, fertilization has a negligible impact on the development and wellbeing of their green pets. Your houseplants will still thrive even if you never fertilize them. I won’t dispute that their growth will be a little slower and that there won’t be as many flowers, but I think it’s crucial to cross all the ts and stress that fertilizer is not really necessary.
What indoor plants actually require to survive
The two most important components are enough lighting and proper hydration.
People err when they refer to “feeding their plants,” as in applying fertilizer. Light is the real food for all green plants. Plants transform solar energy into the sugars and starches they require for growth thanks to the chlorophyll in their leaves and stems. If a plant doesn’t get enough light, it will eventually die, usually slowly from starvation. Its days are still numbered, no matter how much fertilizer you give it. Each plant naturally has a preference for the amount of light it requires (full sun, partial shade, shade, etc.), but all plants require light to survive.
Watering is just as crucial as light. Lack of water causes plants to frequently fall over extremely quickly. Because withering plants are so visually apparent, most gardeners quickly realize they need to water their houseplants frequently. Those who fail to understand this concept quickly label themselves as having “black thumbs” and give up on indoor horticulture. Of course, too much water is no better than not enough because rot can develop when plants are left in soggy soil for an extended period of time. Always remember the Golden Rule of Watering: Don’t water again until the soil feels dry to the touch.
Houseplants need the right temperature to survive as well. If you leave your jade plant outside over a winter in a northern region, you’ll quickly realize that most indoor plants require tropical temps. We already heat our houses to tropical degrees, so temperature isn’t often seen as a big component in caring for houseplants. As a result, the majority of us currently provide the ideal temperature for the typical houseplant. Dispute settled!
Atmospheric humidity is the fourth crucial element for the survival of indoor plants. Most indoor plants, with the exception of succulents, like consistently humid air, but this isn’t often the case in our houses, especially in the winter or when the air conditioner is running. You might need to figure out a means to raise the ambient humidity in such circumstances.
So, I hope we can all agree that taking care of your plants’ demands for light, water, temperature, and humidity will lead to success with houseplants. You shouldn’t worry about fertilizer until you have taken care of them.
Why? Because plants only require relatively little amounts of minerals (plant nutrients), many of which are naturally present in their environment without the need for commercial fertilizer.
First of all, the potting soils you use to cultivate your plants already include minerals; additionally, as the potting soils gradually disintegrate over time, more minerals are released. Additionally, every time you repot your plants, you provide them with new nutrients. Remember that tap water contains minerals that plants can use to develop as well. Additionally, plants take in dust from the air around them, which also contains nutrients. For all those reasons, plants that are never fertilized yet manage to thrive and even grow.
Therefore, fertilizer is not absolutely necessary for your plants. Rather, consider it a “growth supplement.” Use it sparingly, and ideally only when the plant is actively growing. And keep in mind that any fertilizer will work when you decide it’s time to fertilize your indoor plants. Plants can’t read fertilizer labels, after all!
