Plant growing is one of the interesting and productive hobbies. You can grow a mighty flower from a small seed and make your house feel like your home. But to do so, there's something you would want to know and be capable of. First of all, you need self-discipline since plants cannot ask for water or sun. You should also learn about fertilizers and proper nutrition. Everything in life has its demands, and every plant type has its requirements. But if you know what they are, your indoor flora will look perfect for as long as possible. If you ever wondered: “How often should I fertilize my potted plants”, this article is for you.
Key Nutrients
Here are the most important elements every plant needs:
- Nitrogen (N). It is a major component of amino acids, that build proteins, and also chlorophylls, that photosynthesize.
- Phosphorus (P). It is especially useful for seedlings and younger plants. It aids in cell division.
- Potassium (K). It is necessary for a multitude of things. Cell development, fighting off diseases, transporting sugars, and even photosynthesis.
Using those three elements is very much a requirement. Secondary nutrients include calcium, magnesium, and sulfur. Using those helps in enzyme production. If you know how everything works, you’ll understand when to start fertilizing indoor plants.
Fertilizer Types
Here are the most common options available:
- Liquid Fertilizers. These are diluted with water and applied during watering. Plants absorb them quickly.
- Granular Fertilizers. These look like little pebbles and are sprinkled near roots. They release nutrients over months, providing a continuous supply of useful elements.
- Organic Fertilizers. These are made from natural materials like compost or manure. They improve the health of the soil and gradually give nutrients to your vegetation.
Like everything in life, each fertilizer comes with pros and cons. That is the reason why you need to fully understand the needs of your plants. How often should I fertilize my potted plants? Learning all the ins and outs of fertilizers will give you an answer.
When Your Plants Need Fertilization?
Sometimes, if you don’t provide the fertilizer long enough, the plant starts showing signs.
- Yellowing leaves. If you see yellow leaves, there is a problem with watering — either too much or too little.
- Slow or stunted growth. If your plant does not develop properly, there is a problem. In nutrition, watering, or fertilization.
- Wilting. If, despite watering, the plant wilts, check its root system and the fertilizers you use.
Applying Fertilizers Rightly
When you’ve bought the right nutrition, there are rules for applying it. Read through these useful tips to understand, how to use fertilizers safely.
- Liquid Fertilizers. Read the instructions. Dilute the fertilizer accordingly. Apply it during regular watering. Ensure the soil is moist. It prevents burns.
- Granular Fertilizers. Check the recommendations for your plant. Sprinkle the right amount around the base. Gently mix it into the soil. Be sure to water the plant after applying. It activates the nutrients.
- Avoid Fertilizer Burn. Don’t overuse any fertilizer. Too much can cause root burn. Can also damage the plant's leaves. Start with a smaller amount if you are unsure.
- Even Distribution. Spread the fertilizer evenly to avoid over-concentration. It ensures the plant will get all types of nutrient needs in a balanced way.
Never fertilize any plant when in its dormant phase. It usually occurs during winter. The plant is in a zero-growth stage and hence cannot utilize the provided nutrients.
Additional Fertilizing Tips for Different Types of Indoor Plants
Plants have different nutrient needs, and that means the fertilizing schedule does, too. Refer to this list for specifics.
- Succulents and Cacti. These plants require very little fertilizing. Use a weak, balanced liquid fertilizer every 4-6 weeks in spring and summer.
- Flowering Plants. How often should I feed my flowering plants? Flowers need additional nutrients, mainly phosphorus to maintain their blooms. Apply high-phosphorus fertilizer on your plants and re-feed every 2 to 4 weeks while in bloom.
- Foliage Plants. Foliage plants will appreciate regular feedings with high-nitrogen-based fertilizers. A balanced fertilizer may be used monthly during the growing season.
- Herbs. Herbs are light feeders; hence, a small amount of fertilization would work. They require a weak liquid fertilizer every 4-6 weeks.
Different plant requirements may vary in type or frequency of fertilizer.
