For indoor herbs, we recommend a water-soluble fertilizer. We suggest using a liquid fertilizer with a balanced formula that includes nitrogen, phosphorus, and potassium. If you find that your plants are not growing at their optimal rate, try using a fertilizer with more nitrogen.
When you water your plants, you should use at least 1/4 of the recommended dose of fertilizer in the water. The reason for this is that the excess fertilizer will leach out of the soil as it drains through the potting medium and may damage any nearby plants or cause nutrient burn to your own plantings.
Tomato and vegetable fertilizer
- Fertilizer for tomatoes and vegetables should be used to help your plants thrive.
- Choose a fertilizer with high nitrogen content, such as 20-20-20 or 18-18-18. Nitrogen is responsible for leaf growth, which helps the plant produce more fruit than it would otherwise.
- Choose a fertilizer with a high phosphorus content, such as 8-24-8 or 20-10-0. Phosphorus aids in root growth and the overall health of the plant so that it can produce more fruit over time.
- Choose a fertilizer with a high potassium content, such as 6-12-12 or 4:10:14:2 MOA (which stands for magnesium oxide sulfate). Potassium promotes healthy blooms on flowers and fruits by helping build up cell walls within them—in other words, you’ll want to make sure your plants are receiving plenty of this nutrient.
A houseplant fertilizer is a slow-release fertilizer that is applied to houseplants to keep them healthy and strong. Houseplant fertilizers are usually a combination of three nutrient elements: nitrogen, phosphorus, and potassium. The best place to apply fertilizer is in the soil or potting mix around their roots; when it’s time for your herbs to be fertilized again you’ll see signs of new growth at the top of each stem.
Houseplant fertilizers are usually applied once a month during periods of active growth (March through September). They’re available in liquid or powder form with prices ranging from $3-$7 per container depending on potency/quantity ratio.
The liquid form is more concentrated than the granular form, so you’ll use less of it. It’s also more expensive, but if you’re looking for immediate results and don’t want to deal with measuring fertilizer, this may be your best option.
Liquid fertilizers can be used with drip irrigation systems because they are dissolved into water and delivered directly to the plants by their roots. If you opt for a drip system or any other type of watering that allows for precise amounts of fertilizer solution application, using a liquid fertilizer will allow you to get even more bang for your buck.
When using liquid fertilizers in conjunction with a fertilizer meter (which measures how much water is being applied), pay extra attention to how much product is going onto each plant so that they’re receiving enough nutrients without getting too much—or worse: not enough.
Granular fertilizer is slow-release and designed to be used on established plants. This kind of fertilizer is best for plants that are not in containers, as they require a consistent supply of nutrients over time. Granular fertilizers also work well with container-grown herbs, though the dosage will vary with each plant.
One drawback to granular fertilizers is they can be expensive: these products cost more than liquid fertilizers because they contain more nutrients per ounce and therefore require less frequent application. However, there are many benefits to using granule fertilizers: they’re easy to apply (you just sprinkle them on top of your soil), environmentally friendly (no runoff into streams or waterways), and safe for children or pets who might come into contact with them
The Best Fertilizer for Indoor Herbs is the Tomato and Vegetable Fertilizer.
Tomato and vegetable fertilizer is the best choice for indoor herbs. It has a good balance of nitrogen, phosphorus, and potassium for your plants. The liquid form is generally easier to administer than the granular kind. If you’re growing herbs that need more nitrogen (like basil), then tomato fertilizer would be a good choice for you. If you’re growing herbs that need more phosphorus (like parsley), then choose vegetable fertilizer instead.
How To Apply
- Prepare the soil by adding a nutrient-rich fertilizer or compost. Mix this in thoroughly with a garden trowel or hand rake.
- Water the plants well before applying the fertilizer, so that their roots are hydrated and able to absorb the nutrients more easily.
- Apply the fertilizer evenly over all of your plants’ root zones, then water them again to help distribute it throughout the soil (but don’t overwater). Repeat this process once per month for best results; more often if you have many plants in one area together.
If you are in the market for a fertilizer that will give you success with your indoor herbs, then tomato and vegetable fertilizer is an excellent choice. Tomato and vegetable fertilizers have many benefits over other types of fertilizer such as being easily accessible at your local garden center or hardware store, being easy to apply, and providing high levels of nitrogen which is needed for healthy herb growth. If you want to ensure that your indoor herbs grow quickly, use this type of fertilizer every two weeks during their growing season (spring through fall).
