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.
When in the springtime should I begin fertilizer my plants?
Roses are among the shrubs that are most frequently planted in our landscapes because people adore them. Landscape roses that are hardy and trustworthy are usually incor…
In general, when landscape plants start to grow vigorously is the best time to fertilize them. The conclusion of a plant’s growing season is the worst time to fertilize it. For instance, trees wake up and start growing in the early spring, and they normally receive one fertilization in February or March. We often fertilize shrubs once in the spring or early summer when they are at their most active. Late March or early April is the time to fertilize lawns, and midsummer is the time to fertilize again.
Vegetable gardens and flowerbeds are often treated right before planting. It’s crucial to fertilize plants, especially flowers and vegetables. These plants should perform at their highest potential, and fertilizers can help.
Not all growth starts in the spring. For instance, Louisiana irises reach the end of their growing season in the spring and go dormant during the summer. In October, when they start to grow, is when you should fertilize them. On the other hand, trees and shrubs should not be fertilized in the fall because they are going dormant.
When ought I to give my plants food?
Typically, during the growing season, feeding takes place in the spring or summer. Even plants that flower in the winter rarely require fertilizer during that time.
How can indoor plants be naturally fed?
Your indoor plants will remain strong and healthy with the help of natural houseplant fertilizers.
You probably already have a handful of the numerous products that you can use as natural plant fertilizer in your home.
Natural fertilizers for indoor plants are effective since they enrich the soil with vital elements including potassium, nitrogen, calcium, magnesium, and phosphorus.
Natural fertilizers decompose gradually, ensuring a steady supply of nutrients for the growth of your indoor plants.
You can use one or a combination of these organic components to create a homemade liquid fertilizer for indoor plants.
Can indoor plants be fertilized too soon?
As a general rule, only fertilize indoor plants when they are actively growing. While they are dormant, feeding them might cause their foliage to burn or even result in their death.
Don’t overfertilize your plants. Follow the instructions on the product you’re using because using too much can be just as bad as using too little. You should halve the concentration of liquid fertilizers if you want to be safe.
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
Is it possible to simply sprinkle Miracle Grow around plants?
Plants that are bouncy and fruitful are the result of judicious fertilization. Along with routine soil application, foliar feeding involves spraying liquid fertilizer onto leaves. It isn’t advised for houseplants and should only be used on outdoor plants when the weather is good. It promotes faster transport of nutrients via plant tissue and arteries. Spraying leaves in a hot, humid environment could have the opposite effect of what is intended. It is preferable to let the leaves alone in certain circumstances.
Before or after watering, should you feed your plants?
Fertilizers or plant meals can be applied in many different ways. Each has benefits and can be applied in various situations. When plants are growing, liquid feeds must be sprayed frequently, typically every 10 to 14 days, and are an excellent pick-me-up. Granular meals get to work quite soon and continue to provide nutrition for several weeks.
For several months, controlled-release feeds offer a consistent flow of plant nutrients from a single application as and when the plants require them. Only when the soil is sufficiently moist can all plant nutrition be absorbed by the roots. Apply water first before feeding the plants with either solid or liquid plant meals if the soil or compost is dry.
Apply the proper amount; don’t increase it for more luck. The application rate has been calculated to provide the most benefits. Inadequate dosage might hurt your plants and is wasteful.
By hose-end feeder
With contemporary tools like the feeder, it is simple and rapid to water soluble plant foods over huge regions. The water jetting through the hose gradually picks up and dilutes the plant food that has been dissolved in the container. When you purchase the feeder, it already comes with a sachet of soluble plant food; all you need to do is add water, attach the jar to the feeder head, and you’re ready to go. You can also utilize a system of concentrated liquid plant feeds, which consists of nothing more than a bottle you screw into a feeding head and the precise dilution of the feed by the water pressure from your hose.
By hand
Examine the suggested pace before you begin. On kitchen scales, weigh the quantity in your own “handful” to compare it to the suggested application rate. After applying the plant food to the designated area, rake it in. Clean your hands after using.
Through a watering can
Unless it has been completely washed out and rinsed multiple times, use a watering can that has not previously been used for weedkillers. Add the amount of plant food recommended on the pack or bottle after adding clean water from the drinking tap or waterbutt. Water the soil around plants after thoroughly stirring until the mixture has dissolved.
By spreader
If you have access to a mechanical spreader with wheels, treating expansive parts of the grass is simple. Compared to applying by hand, it will be more evenly distributed and can treat big surfaces quickly. To prevent rust, carefully follow the setup instructions, and empty the hopper after each usage.
The advantages of controlled-release plant foods
Foods that are wholesome and practical to utilize should be planted for continuous or regulated release. From a single application, they offer a consistent flow of plant nutrients. More plant foods are released during warm weather because plants develop more quickly. When temperatures drop, plant growth slows, and nutrient release follows suit.
For use in the soil surrounding trees, shrubs, and flowering plants, you can purchase loose granules such as continuous release plant food or controlled release plant food. For use in hanging baskets, pots, tubs, and other containers, continuous release plant food tablets or controlled release plant food tablets are high in potash and contain magnesium and trace minerals.
When planting, continuous and controlled-release plant foods can also be added because the metered release won’t burn or hurt the roots.
Just before they begin to grow or while they are actively growing, plants need to be fed. For the majority of plants, this occurs throughout the spring and summer when they are producing new leaves, stalks, and flowers. In late autumn or winter, avoid feeding outside plants since too much nitrogen may promote soft growth that is more vulnerable to frost damage.
Are coffee grinds safe to use on houseplants?
Nothing gets the day started off right like a hot cup of coffee. You may be wondering if you can fertilize houseplants with your brewed coffee grounds if you are a plant owner.
Coffee grounds are frequently used by individuals as a quick, inexpensive, and environmentally responsible approach to maintain healthy plants.
Indeed, coffee grounds are good for houseplants! Due to its high nitrogen content, abundance of micronutrients, and great water retention, this rich organic material is beneficial for your plants. Composting is hands-down the greatest technique to use coffee grounds on indoor plants.
Utilizing your coffee grounds in a handmade potting soil mixture is an additional excellent choice. Additionally, leftover liquid coffee can be used to make a basic plant fertilizer.
Bear in mind that adding coffee grounds will make the soil more moist. For plants that prefer moist soil, this is perfect!
However, it is advisable to keep your coffee grounds compost and potting soils away from plants like succulents and cacti that demand dry soil.
You shouldn’t sprinkle uncooked coffee grounds straight on your houseplants. Applying raw coffee grinds can significantly raise the soil’s moisture content. This may harm the growth of your plants in a number of different ways.
Your indoor plants will be grateful that you learned how to maximize the benefits of your coffee grinds!
