Type of Indoor Plant Fertilizer Best For Houseplants

indoor plant fertilizer

There are several different kinds of indoor plant fertilizers available, but the best indoor plant fertilizers must contain a blend of slow-release granules, a combination of nitrogen and potassium salts, and a balanced combination of phosphorous, sulfur, and potash. The best indoor plant fertilizer must contain a slow-release rate of about half strength for plants need nutrients throughout the growing season. Fertilizer packets should list the proportion of phosphorous, potash, and sodium that each package contains.

Indoor Plant Foods

Indoor plant foods that are full of nutrients are the best choice for most indoor plants. You can buy these nutrients in bulk at nursery stores and online, but it is important to check price, read the package labels, and make sure the ingredients are exactly as they say they are. Plants that have strong roots need extra doses of nutrients every few days, while those with medium roots can receive these nutrients every two weeks. Plants that don’t have very strong roots or aren’t growing well should be fertilized only once a month.

It is recommended that new plants are started from seed, since this allows you to control the amount of water and nutrients your plants need. Keep in mind that seeds will need more water than your perennials or annuals because seeds are still very much alive. For this reason, you should wait until your garden is established before trying to grow seeds.

Do The Comparison

When comparing your indoor plant foods at home versus what you get at the local garden center, check the concentration of key nutrients listed on the package labels. The most effective indoor plant fertilizer is a slow release, granular, slow-release plant food. Organic fertilizers and slow release fertilizers differ in many ways, including their delivery methods. The most efficient indoor fertilizers are made from recycled food packaging. Slow release fertilizers use a liquid suspension that contains nitrates, nitrites, and phosphate to deliver high levels of plant nutrition over long periods of time.

Ammonia, potassium nitrate, and phosphate are common fertilizers used in the home garden. Amazon liquid fertilizer comes from organic waste materials, including peat moss, bark, and straw. Amazon slow release fertilizer is made with recycled paperboard, sewage sludge, or sewage from a septic system. These are all slow release materials and are safer for your plants than concentrated fertilizers that are readily available at your local garden center. Amazon slow release fertilizer has a low-pH level and is safe for your plants.

It Depends On Your Plants As Well

The amount and quality of plant food you select to feed your indoor plants will depend on the type of plants you are growing, how large they are, and how you care for them. Indoor plants take longer to grow than their outdoor counterparts, so you have to take that into account when choosing the best type of indoor plant fertilizer. You also have to be aware of the pH level of the soil you are growing plants in.

Ending Note

If you are using slow-release fertilizers, then you have to be sure to supplement them every few weeks with high-quality slow-release fertilizers like those from Amazon. For houseplants, it is best to use high quality liquid plant foods and organic fertilizers. However, you can always mix in a little houseplant fertilizer when you water them and replenish them from time to time.
