Best Fertilizer For Indoor House Plants

Indoor house plants need fertilizer just like outdoor plants. Fertilizer is the best way to ensure your indoor plant will be healthy and grow as best it can.

Indoor house plants are not out in the elements, so they do not need to be fertilized as often or in the same quantities as outdoor plants. However, they still need some fertilizer to maintain their health and growth. If you give your indoor house plant too much fertilizer, it could die from being overfed. If you give your indoor house plant too little fertilizer, it will not grow properly and may become sickly or even die from lack of nutrients.

You should fertilize your indoor house plant about once a month during its growing season (spring through fall). This will help keep it healthy and growing strong.

Your indoor plants need specific fertilizers for them to thrive. But finding the best fertilizer for your plant can be challenging. The market has many fertilizers that can work for different houseplants, but how do you know which one is the right fit? This article offers an overview of some of the best fertilizers for indoor plants and will help you find a fertilizer to suit your needs.

1. Bamboo Plant Fertilizer Sticks

  • Bamboo Plant Fertilizer Sticks

These are a great way to fertilize your bamboo plant. The sticks are made up of natural ingredients and are specifically formulated for bamboo plants, so you can be sure they’re going to work well. We love this fertilizer because it has a slow-release formula that lasts for months, so you won’t have to worry about reapplying as often as with other brands of indoor plant food. Plus the bamboo sticks come in different sizes depending on the size of your topiary (or shrubbery if you prefer) which makes them perfect if yours isn’t very big or if you have multiple pots full of these lovely accent pieces around the house. You can buy these fertilizers at any number of garden stores such as Home Depot or Lowe’s but also online through Amazon where prices start at just under $10 per pack.

2. Osmocote Plus Indoor/Outdoor Smart-Release Plant Food

This indoor plant food is made for the type of soil you have, whether it’s potting soil or natural garden soil. The key to this fertilizer is that it releases nutrients gradually over time, so your plants will get what they need without being overfed. It also contains an oxygenating agent that helps maintain healthy root systems and protects against root rot, which can ruin a plant even if there are no signs of damage yet.

The active ingredient here is high nitrogen, so this is best for those who want their plants to grow quickly rather than stay small and slow-growing (or vice versa). It’s also good for houseplants because it’ll work with any type of container — plastic or clay pots — as well as outdoor plants in any kind of ground from loamy sand up to heavy clay soil. This product works on all types of indoor and outdoor flowers and vegetables alike; we’ve used it on everything from basil plants in buckets on our balcony to potted ferns in our basement apartment by the window.

3. Miracle-Gro Water Soluble All Purpose Plant Food

Miracle-Gro Water Soluble All Purpose Plant Food is a good choice for indoor plants. It contains the right mix of nutrients and moisture to keep your house plants thriving. The liquid formulation makes it easier to apply than other fertilizers, which is especially helpful if you have limited mobility or have trouble bending down with ease.

It comes at a cost though—it’s more expensive per container than its dry equivalents. However, if you want something that will be easy to use and will not burn your plants when applied too liberally (as can happen with some dry products), this product might be worth spending extra on.

4. Jack’s Classic Indoor Plant Special Fertilizer

Fertilizer is a supplement to the nutrients already in the soil. If your plant’s soil is of good quality or if you’re using a potting mix, it will not need fertilizer. You may also choose to not use fertilizer at all if you are using a good quality potting mix that incorporates compost, which will provide extra nutrients for your plants.

If you do wish to use fertilizer for any reason, Jack’s Classic Indoor Plant Special Fertilizer comes highly recommended and can be found at most garden centers. The price is comparable with other fertilizers on this list—around $12 per bag—and the label states that it contains everything necessary for healthy indoor house plants including micronutrients and organic material like kelp extract, and humic acid, and fulvic acid (all important components of healthy soils).

5. Schultz 10-15-10 Plus 2% Iron Aquatic Plant Food

This is a great fertilizer for indoor house plants. It contains a wide range of nutrients, so it can be used for both indoor and outdoor plants. The Schultz 10-15-10 Plus 2% Iron Aquatic Plant Food is good for plants that are in pots or hanging baskets and can be used for all types of plants, including cacti and succulents.

The price of this product is $14.99 per 1 lb container (for the size I reviewed).

How To Apply

  • Follow the directions on the label for how to apply fertilizer.
  • Apply fertilizer at the recommended interval (usually weekly or monthly).
  • Apply fertilizer to the soil and not directly onto the plant. This will help prevent damage from excess moisture. You can do this by applying it around the perimeter of your houseplant’s container, or you can sprinkle it on top of a layer of mulch in your houseplant’s pot. Fertilizer should be applied at least once a year, but more often if you’re growing plants with high-light needs in direct sunlight.

When To Apply

To get the most out of your indoor plants, you’ll want to fertilize them on a regular basis. But when is the best time to do so?

Spring

In the spring, start applying fertilizer two weeks after you’ve planted your houseplants. This will give them time to establish new roots and begin taking in nutrients from their surroundings. If you’re growing plants indoors from seeds or cuttings, fertilize immediately after planting. The same goes for winter crops that are grown indoors during colder months: apply fertilizer once sprouts appear in late winter or early spring (typically February).

Fertilizers can be purchased at local gardening stores or online through online plant supply stores. Fertilizer can also be made at home using a variety of ingredients, such as:

  • Fish emulsion – fish emulsion is used by many people because it’s easy to find in stores, but you can make your own fish emulsion with the following steps:
  • Take two pounds of fish parts (heads, bones) and boil them in four liters of water for twenty minutes then strain out the liquid into another container;
  • Once strained add two cups sugar plus 4 tablespoons powdered seaweed kelp together with one tablespoon oil (olive or corn), stir well; 3) In a separate container mix half a cup each lime juice & baking soda then add this mixture slowly into your broth being careful not let any foam build up over the top surface

Conclusion

Indoor plants can be beautiful additions to any home, but without the proper care, they’re just another dead thing. The best way to keep your plant alive and help it grow is with fertilizer. Fertilizer contains nutrients that will help your plants thrive and give them a healthy boost.
