Spider Plant Fertilizer Requirements: Tips On Fertilizing


If you’re a plant person, you probably know by now that spider plants (Chlorophytum comosum) are some of the easiest and most carefree houseplants out there. These long-lasting houseplants are known for their distinctive mop of leaves that resemble a spider’s web. They can grow long and arching stems, and they give off a beautiful and sweet scent. Spider plants love bright, indirect sunlight and moist soil, and they’re also tolerant of heat and dry air. While they can be forgiving and tough, spider plants do require fertilization every few months for best results.

With a few proper care tips, you can expect your spider plant to grow several new plants for years to come. Let’s take a look at how to fertilize a spider plant and give it the best chance of success.

What is a spider plant?

A spider plant (Chlorophytum comosum) is a popular houseplant because it is easy to grow and care for. It is a tropical plant that does best in bright, indirect light. The soil should be kept moist but not wet. Fertilizing a spider plant is actually quite easy – all you need is a standard houseplant fertilizer and a watering can.

Why should I fertilize my spider plant?

Spider plants are a popular houseplant because they’re easy to care for and require very little maintenance. However, that doesn’t mean they don’t need any attention at all – in fact, spider plants need to be fertilized regularly in order to thrive. Why is fertilizing important? Fertilizing helps to provide the spider plant with the nutrients it needs to produce healthy leaves and spiderlings (baby spider plants).

Spider plants need a steady stream of nitrogen, phosphorus and potassium to grow well. While it’s possible to get these nutrients from your soil, it’s often difficult to get the right balance. Fertilizers make it easy to give your spider plant the nutrients it needs without overloading it with any one nutrient.

There are a number of different fertilizers available on the market, so be sure to select one that is specifically designed for houseplants. Fertilizing a spider plant is easy and can be done with any type of plant food.

When should I fertilize my spider plant?

The best time to fertilize your spider plant is in the spring and summer, when it’s actively growing. You can use a balanced liquid fertilizer or water-soluble fertilizer. Be sure to follow the instructions on the package, and dilute the fertilizer if it’s too concentrated. Feed your spider plant every two to four weeks, depending on how actively it’s growing. Stop fertilizing in the fall and winter, when it’s in a dormant stage.

You should fertilize your spider plant about every other week. In the spring and summer, use a balanced 20-20-20 fertilizer. In the fall and winter, use a 10-10-10 fertilizer. If you’re using a liquid fertilizer, mix it with water at a rate of 1 tablespoon per gallon. If you’re using a powder fertilizer, mix it with water at a rate of 1 teaspoon per gallon. You can also use a well-decayed organic matter like diluted cow manure or coffee grounds as a fertilizer.

How often should I fertilize my spider plant?

You only need to fertilize a spider plant at least four times a month. During the spring and summer, use a water-soluble fertilizer every month. In the fall and winter, use a slow-release fertilizer every other month.

So, when is the best time to fertilize a spider plant? The answer depends on what type of fertilizer you’re using. If you’re using a liquid fertilizer, you’ll want to fertilize your spider plant every two weeks. If you’re using a slow-release fertilizer, you’ll only need to fertilize once a month.

What types of fertilizers should I use for my spider plant?

Your spider plant will thrive with a regular feeding of liquid plant fertilizer. You can find this at any garden center or home improvement store. There are a few different types of fertilizers you can use for your spider plant. A water-soluble fertilizer is the best option, as it will release the nutrients slowly and steadily into the soil. You can also use an organic fertilizer like compost, or a balanced fertilizer that contains nitrogen, phosphorus, and potassium. Be sure to follow the instructions on the package, and don’t over-fertilize your spider plant—too much fertilizer can actually be harmful!

When it comes to fertilizers, it’s always best to start with a weaker solution and work your way up to a stronger one if needed. Be sure to read the instructions on the package, and test the fertilizer on a small area of the plant before applying it all over.

Fertilizers to avoid for spider plants

Now that you know how to fertilize your spider plants, it’s important to be aware of which fertilizers to avoid. Nitrogen-based fertilizers are the most harmful for spider plants, as they can cause them to produce excessive amounts of foliage and stunt their growth. Avoid fertilizers with high levels of nitrogen, phosphorus and potassium (the three main ingredients in most fertilizers) if you want your spider plants to thrive. Stick to organic or water-soluble fertilizers that are specifically made for houseplants to ensure your spider plants stay healthy


The spider plant, also known as the airplane plant or Chlorophytum comosum, is an excellent houseplant for anyone looking to spruce up their indoor space with minimal effort. The spider plant is very low-maintenance and requires infrequent watering, making it a favorite among busy homeowners. Spider plants are easy to grow indoors and will flourish under the right conditions.

If you have a spider plant, it’s important to fertilize your plant regularly for healthy growth. You should fertilize your spider plant when the older leaves start to turn yellow and die. We recommend using a fertilizer with an NPK ratio of about 10-10-10 or 20-20-20, but you can use a fertilizer that is balanced for blooming plants instead if you’d like.
