Although watering houseplants may seem like a straightforward operation, many people either overwater them or neglect them until they get parched. Generally speaking, the potting soil for indoor plants should be kept damp but not soggy. In the spring and summer, they typically need watering once or twice a week; in the fall and winter, they require less watering. However, this isn’t always the case, depending on the kind of houseplant.
- Only give orchids a small bit of water once a week to water them.
- Succulents and cacti need relatively little water. When the potting mix has dried out, only water.
- Water citrus plants more frequently and consistently than you would other houseplants.
The Westland Watering Indicator makes it easier to know when to water. This watering stick is very simple to use and may be used all year round. Just insert the stick into the pot of compost. The indicator will then turn red to let you know when the plant needs extra water. When no additional water is required, the indicator will turn blue. Within two hours of watering the plant, the indicator’s color should shift from red to blue.
Another crucial factor is the type of water used on indoor plants. This is due to the fact that many plants are sensitive to the salts and chemicals found in tap water. So it is advisable to use rainwater to water your plants.
Feeding
To promote lush, robust growth, indoor plants must be fed while they are developing. Only while a houseplant is actively developing, not when it is dormant, should it be fed.
During the growing season (spring and summer), the majority of indoor plants need typically be fed every other watering, or around every 10 to 14 days. In the fall and winter, feed indoor plants after every fourth watering because they will need fewer nutrients.
Using a liquid concentrate feed is a good approach to feed houseplants. These are a fantastic way to feed and water your plant simultaneously. They work best, though, when the mixture isn’t created too powerful or too weak. Given that it is filled with the necessary nutrients, Westland Houseplant Feed is a fantastic plant food for indoor plants. Additionally, it contains a simple measure doser that requires only a squeeze of the bottle to fill the dosing chamber. Any extra plant food will be removed by the doser, leaving you with a 5ml dose to mix with 1 liter of water. This indicates that the combination you use to feed your plants is the proper strength.
The list of specialized feeds for various types of indoor plants that include the precise ratio of nutrients required for their growth is provided below.
- Feed for succulents and cacti offers nutrients that improve flowering.
- Citrus feed: provides nutrients that promote fruit development and set.
Which month should indoor plants 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, fertilizing your houseplants can seem intimidating at first. However, once 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.
When should I fertilize my plants?
- Pick a food for plants. Continuous release fertilizers are fantastic if you like a little hands-off approach, but liquid or water soluble plant feeds may be a better choice if you often work in the garden.
- Get up and start eating. Feeding your plants in the early spring will help you achieve the best outcomes since it will provide them the nutrients they need to get the growing season started. Continue feeding as directed on the label on a regular basis.
Wait 30 days before applying fertilizer to newly planted plants in Miracle-Gro soil or potting mix because your plants will already be getting plenty of nutrients from the soil.
- Add a reminder. Sometimes the hardest thing is remembering to feed your plants. Depending on the product you have, you will need to feed every 7–14 days if you’re using a water-soluble or liquid plant food.
Fertilizers with continuous releases are applied less frequently, typically every six weeks. To determine how frequently to use a product, always consult the label. Once you are aware of the proper feeding plan, you may assist yourself stay on track by setting a regular reminder on your phone or smart speaker.
How frequently should I feed plant food to my houseplants?
I had a variety of roles as a founding worker at Gardener’s Supply over the years. I currently run my own business, which is called Johnnie Brook Creative. A huge vegetable garden, a seasonal greenhouse, a cutting garden, perennial gardens, a rock garden, a shade garden, berry plantings, numerous container plants, and a meadow garden are among the gardens surrounding my Richmond, Vermont, home. The garden is the only place I would rather be. Check out this Garden Gate magazine video interview from January 2021 if you’re interested in learning more.
The identical type of tray and soil were used when these seedlings were planted at the same time. The addition of fertilizer was the only change.
The majority of gardeners do not fertilize their plants, according to a National Gardening Association survey. However, there is no simpler approach to enhance a plant’s general appearance, flower and fruit production, and resistance to pests and diseases.
I adore plants and detest the idea of them going hungry. I also want every gardener to succeed as much as they can. So pay attention if you’re one of the millions of gardeners who don’t fertilize their plants.
Pots and planters, like this Viva Self-Watering Hanging Basket, will flourish with regular feeding.
Buy a water-soluble, organic plant food first. Because I’m going to advise you to fertilize frequently, I suggest organic. It’s important to follow the directions on the container when using synthetic fertilizers like “the blue stuff,” as it’s simple to “burn” your plants by using too much chemical fertilizer. PHC All-Purpose Fertilizer is made from organic ingredients, simple to use, and highly productive.
Two times per week, start fertilizing your container plants. Give your houseplants a weekly fertilizer. Every two to three weeks, give your garden plants a fertilizer. Give your landscape plants a monthly fertilizer.
Observe what transpires. I’m sure you’ll notice a significant improvement. There will be more flowers and fruit on your larger plants. They will also be more resilient to drought and other environmental stresses, as well as to pests and diseases.
Applying a liquid fertilizer to your soil is not a replacement for amending it with compost and granular organic fertilizers. Your plants are like teenagers during the growing season—they urgently require food! Since they are readily available right away, liquid fertilizers offer that rapid remedy.
Both your soil and your plants benefit from using compost and granular organic fertilizers. They should be added as you are setting up your garden or your containers at the start of the growing season. Apply them once more at the end of the season to replenish lost organic matter and nutrients for the greatest results. This will ensure that your soil has sufficient of reserves to support your finest garden yet next spring.
Three Reasons Container Plants Need Extra Help
What makes plants growing in pots and planters special enough to require their own specialized fertilizer? Here are a few ways that plants grown in containers differ from those in gardens.
- restricted roots Plant roots can extend many feet or even yards in the garden in search of water and nutrients. On the other hand, when plants are cultivated in pots, their roots are constrained and are unable to extend out into the surrounding soil in search of nutrition. You must provide container plants with the water and nutrients they require for growth.
- mixes for soilless planting. Many supposedly soil-containing mixtures are really comprised of peat, coir, and/or perlite instead of genuine soil. They have the advantages of being lighter and providing greater drainage than garden soil. On their own, soilless mixtures provide little to no nutrition. This means that you must provide all of the nutrients in the form of fertilizer that the plants require.
- No helpful microorganisms. In order to guarantee that there are no plant disease organisms, soilless planting mixes have been sterilized. That implies that there aren’t any helpful germs either, though. Some fertilizers are broken down into forms that plants can utilise by soil bacteria. That’s acceptable in garden soil, but in containers devoid of soil bacteria, the nutrients must be available to plants right away.
