When indoor plants get thirsty, they wilt. When their leaves don’t receive enough sunshine, they become pale and lanky. They get crispy at low humidity levels, while they may go rotten at high humidity levels. It is far more difficult to determine when to fertilize houseplants. Other than possibly delayed or sluggish development, which is often scarcely noticed by houseplant parents, your plant won’t provide you a direct signal that it’s time to feed it. Therefore, you’ll have to take matters into your own hands and utilize houseplant fertilizer on a schedule that is dependent on their growing cycle rather than waiting for a signal from the plant.
There’s no need to unnecessarily complicate the process, but each particular houseplant has slightly variable requirements for houseplant fertilizer levels and frequency. Yes, you could research the specific nutritional requirements of each species of houseplant you look after, but in reality, the vast majority of common houseplants have fertilizer requirements that are sufficiently similar that treating them in a single way is more than sufficient to meet their nutritional needs. It’s true that some houseplants require more food than others. However, a timetable for fertilizing houseplants like the one below provides a solid compromise that both satisfies heavy feeders and prevents you from overfeeding houseplants that just need a little fertilizer.
Here is the recommended fertilizer regimen for the majority of indoor plants. It is based on the growing season’s cycle, which, despite being indoors where temperatures are more stable, affects houseplants in a manner similar to how it affects outdoor plants.
Do indoor plants need to be fed all year long?
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 I feed plant food to my indoor plants?
Your houseplants will likely perform less well if you don’t feed them frequently. Once they have a pot full of roots, you should start giving them regular meals. Give them regular feedings if you want them to stay healthy and produce a lush, appealing show.
Both leafy plants and blooming plants require some feeding at intervals of 10 to 14 days from early spring through summer. The same method, but only when they are in bloom, should be given to indoor plants that only bloom in the winter.
In the winter, should I fertilize my houseplants?
Do indoor plants need fertilizer throughout the winter? Because most indoor plants are not growing throughout the winter, fertilization is typically not required. In the spring and summer, when plants are actively growing, indoor gardeners should fertilize their houseplants on a regular basis.
Can indoor plants be overfed?
Houseplants may suffer if they receive too much fertilizer. In fact, overfertilization can slow growth, leave plants weak, and make them more susceptible to pests and diseases. It might also result in the plant’s eventual death. Stunted growth, scorched or dried leaf margins, wilting, and plant collapse or death are indications of excess fertilizing. Plants that receive too much fertilizer may also have yellowing of the leaves.
Too much fertilizer can also result in salt accumulation on top of the soil, which hinders plants’ ability to absorb water. Place the plant in the sink or another suitable spot and thoroughly rinse it out with water, repeating as necessary, to reduce overfertilization and excessive salt buildup (three to four times). Keep in mind to let the plant drain well in between waterings.
It will be simpler to prevent using too much fertilizer on your houseplants if you fertilize just during periods of active development and reduce the dosage.
Should I always use nutrients when I water?
In the form of N-P-K (nitrogen, phosphorus, and potassium), nutrient solution bottles and fertilizer bags will show how much of each of the three major nutrients is included in the product. For instance, a product marked “10-4-4” will have a weight percentage of 10% nitrogen that is accessible, 4% phosphorus, and 4% potassium.
An ideal ratio for a vegetative fertilizer is 9-4-5, which has high nitrogen, low phosphorus, and moderate potassium. Reduce nitrogen as a plant enters flowering and increase phosphorus and potassium instead. for instance, aim for a 3-8-7 ratio.
Additionally, products are typically separated into “bloom solutions,” which are high in phosphorus for flower development, and “grow solutions,” which are high in nitrogen needed for vegetative growth. If you don’t want to become bogged down in numbers, stick to these general words.
Make sure you just water your plants during the last week or so before harvest to drain out any nutrient buildup in the buds. This process is known as flushing.
Liquid nutrients
Although they can be used outside as well, liquid nutrients are mainly employed for indoor gardening. For quick and effective distribution, liquid nutrients are utilized for weed plants in soil, hydroponics, and other grow media and can be pumped through drip lines, misters, and hoses.
Because liquid nutrients are fast-acting and easily accessible to a cannabis plant’s roots, they can harm plants if you give them too much.
You will want a separate water tank, such as a designated trash can, to mix liquid nutrients into water in order to use them. Additionally, you’ll need to be aware of how much water each of your plants requires. The correct ratio of liquid nutrients should be added in accordance with the amount of water you require and the instructions on the bottle.
It’s crucial to record and keep track of your watering schedule when utilizing liquid nutrients on cannabis plants.
- the amount of water you use
- The quantity and types of nutrients you consume
- How often do you water?
You don’t want to water your plants every time with liquid fertilizers. Use them two waterings on, one off, or every other watering. The complexity of your soil and the condition of your plants will determine this. Your plants will suffer if there are too many nutrients.
Careful monitoring is necessary to ensure that weed plants receive the right amount of nutrients. Many growers start with a solution dose that is lower than advised and gradually increase it until plants respond as best they can. Too little nutrients can cause nutrition burn and lockout, while too many can cause stunted development in plants.
Check your pH
When mixing fertilizers, it’s crucial to purchase a pH meter to evaluate the water’s pH level. In soil, cannabis prefers a pH between 6 and 7, whereas in hydroponic media, it prefers a pH between 5.5 and 6.5. You should test your water frequently and ensure that the fertilizer mix you provide plants is within the proper pH range to prevent nutrient lockout, which prevents your plants from absorbing the nutrients they require.
Should plants be fed throughout the winter?
Like people, houseplants require nourishment to function, especially when they are actively developing. Feeding is required during the months of spring and summer, but not in the winter. Use fertilizer sparingly if you must. The fertilizer should be diluted by at least 50%. You can resume feeding whenever you notice the plant beginning to develop again (usually in late February or early March).

Why do indoor plant leaves sag?
Finding out what’s wrong with a once-beautiful, green houseplant that starts to look sickly might be challenging. Could an illness, a weather-related event, or a dietary deficiency be to blame? If you’re wondering why your plant’s leaves are going brown, it could mean that something isn’t right with the environment in which it is growing. Browning of the leaves can occur for a variety of reasons, but the methods of watering, the humidity level around the plant, and an excess of fertilizer in the potting soil are the most frequent culprits. Here are the solutions to each of these typical indoor plant issues that result in brown plant tips.
Why do plant leaves darken at the tips?
Typically, underwatering, sunburn, or overwatering are the causes of browning leaves.
The soil possibly grew too dry for an extended period of time between waterings if the leaf tips are turning brown and hard. The plant may lose leaves as a result of this. This does not necessarily imply that you are regularly underwatering because the browning may have only occurred once. Although the brown leaf tips won’t turn green again, you can trim the brown margins to restore the plant’s healthy appearance. Go here to learn more.
It may also be a symptom of overwatering if you see brown patches all over the leaves. You’ll typically notice some yellowing of the leaves as well when the plant is overwatered. Go here to learn more.
If you see brown stains in the middle of the leaves, it may be because the leaves are receiving too much direct sunshine. Some plants are readily burned by direct sunlight and are sensitive to it. If this is the case, try shifting your plant to a spot where it won’t be exposed to the sun’s glare.
– If you move your plants from indoors to outdoors in the summer without acclimating them to direct sunshine, this is usually what happens.
