As we come to an end with our Fall Compost Back program, we are aware that many of our subscribers may be spending less time getting their vegetable gardens ready for September than they do during our Spring rotation. However, there are still many methods to make the most of your finished compost at this time of year even if you don’t have a garden. Using finished compost in your indoor plants to promote soil health and plant growth is one of our favorite suggestions!
This is a favorite among the Compost Crew because it doesn’t call for a sizable backyard and can be applied to any plant! To make the most of your nutrient-rich black gold with your houseplants, we wanted to share some recommendations with you.
Compost must be used in the proper quantity to ensure that your plant receives the necessary nutrients without causing harm.
When using completed compost, you can either repot the plant in a mixture of 30% finished compost and 70% of your regular soil mixture, or you can apply a few inches of compost on top of the soil.
A house plant may get root burn if its pot contains an excessive amount of finished compost because the surplus phosphorus is held in the soil and overwhelms the plant. Keep a watch out for browning leaves and generally reduced growth to see if this is happening to your plant. Browning roots are another sign of root burn, however that is harder to spot from the surface. Cleaning the nutrient-rich dirt from the plant’s roots and repotting it in a soil mixture with more balanced nutrients are the best ways to care for plants that have experienced root burn.
Apply compost once or twice a year to your indoor plants to get the most advantages from it.
Given that completed compost often has very fine particles, it makes sense to combine it with soils that have larger pieces in order to promote drainage and prevent soil compaction.
Even though houseplants are sometimes overlooked when utilizing finished compost, doing so can be a simple approach to boost your plants’ general health and encourage growth. The long-term health of your indoor plants can benefit from finished compost since it can help them retain nutrients and moisture. We always enjoy seeing pictures of how you’re putting the compost to use, regardless of how you use your completed compost. Keep an eye out for our customer portal’s upcoming opportunity to acquire your soil amendment in the spring.
Can indoor plants be composted?
Especially when it comes to gardening, compost is quite important. It is the ideal tool to utilize in order to promote plant growth. Animal waste and plant detritus are some of the naturally occurring components of compost.
The additional nutrients the plants may need to thrive properly are subsequently provided by the compost. Compost is formed from organic matter that is found outdoors, thus some people question if it can genuinely be used indoors.
You will be relieved to learn that compost can be used for indoor house plants and pots. Given that compost includes so many nutrients that are essential for your plants’ growth, doing so is actually advised. It doesn’t matter if it’s inside or outside.
As long as the plants continue to receive the moisture and sunlight they require to thrive, compost is typically a fine option for your indoor houseplants and any pots that you maintain indoors. In the end, compost is there to improve the life of the plant, and this is true of every plant, wherever it is.

Simply put, compost is a combination of organic materials that you can use to produce plants instead of soil. It is possible to manufacture it by mixing water, manure, hay, straw, and organic items like leaves. Although it initially seems unusual, compost offers numerous advantages over regular soil.
Compost can be used in place of soil to encourage plant development. To cut down on waste, you can combine the two. By giving plants nutrients, it also contributes to improving soil fertility. Compost as soil eliminates the need for artificial pesticides and fertilizers, which studies have shown to be harmful to the environment.
Which kind of compost is ideal for houseplants?
To maintain healthy development after a year or two, plants may require repotting, so it’s critical to choose a compost that will work best for your plant.
The three types of compost that you can use for indoor plants are multipurpose compost, houseplant compost, and loam-based compost, according to the Royal Horticultural Society.
Peat-free multipurpose compost
The best compost for indoor plants is peat-free multifunctional compost, which should be available on Amazon. However, because of its high organic matter content, the compost sinks to the bottom of the pot as it decomposes, reducing the number of air pores around the roots.
This restricts root growth, conditions them, and encourages moisture buildup that may eventually kill them. You must make room for the roots to breathe since, like leaves, they require oxygen.
The simplest method is to simply add a drainage material, such as horticultural sand, which is readily available and reasonably priced. Garden sand will facilitate better water drainage and help loosen compacted compost. A 1:4 sand-to-compost ratio is appropriate for the majority of houseplants, but a 1:2 ratio is best for cacti or succulents.
Perlite, a type of volcanic glass, can be used in its place if you are unable to acquire sand or feel that it would be too heavy to carry home. This perlite from Mother Earth is a fantastic choice. The same 1:4 ratio can be used with perlite because it is highly porous but doesn’t retain water, making it perfect for balconies or patios.
Vermiculite is a possible alternative because it can increase air porosity as well, but it also stores water and releases it gradually back to the plant as needed. This one can replace half of the compost because it can be put in a 2:2 ratio. The third choice is biochar, which functions similarly to vermiculite but is more difficult to locate. It can be applied in the same quantities as sand or perlite.
Loam-based compost
Compost made from loam, sand or grit, and peat is known as loam-based compost. Plant feeds (or compost) are then gradually added to the mixture.
A soil is said to as “loam” if it has equal amounts of the following three constituents: sand, silt, and clay. The biggest particles, which tend to contain less water but offer good aeration, are made of sand. Despite their small size, clay particles have a tendency to compress and readily absorb moisture. Sand and clay are separated by silt particles, which promote more uniform mixing of the two particles.
In contrast to multi-purpose compost, loam-based compost does not require the addition of drainage materials to increase aeration. However, loam is currently in short supply and most will contain varied particles that do not conform to what is typically regarded as “excellent” loam.
Potting mixes
Peat moss, sphagnum moss, compost for moisture retention, vermiculite, or perlite for drainage are typically included in potting mixtures. They are light and mixed to hold moisture and drain well because they are formulations specifically designed for plants in pots.
You can get potting mixtures that are tailored to the requirements of specific plants. For example, orchid potting mixtures have more bark for better aeration and more sand for better drainage than cactus and succulent potting mixtures. Contrary to pure compost, potting mixes frequently include little amounts of fertilizer that should dissipate after two or three waterings, while some sometimes include more fertilizer to gradually supply plants with nutrients.
Wetting agents are frequently included in potting mixes to lower the surface tension of water, allowing it to permeate the mixture and distribute more uniformly. This is intended to keep moisture close to plant roots to reduce the frequency of watering, although other research contends that this is untrue and may actually condition plant roots.
Warm water should be added to the potting mix prior to planting. This will guarantee uniform moisture distribution throughout the potting mix, saving you the extra trouble of having to hydrate the material inside the pot. To avoid diseases or pests from taking over, you should aim to replace the potting mix every 1-2 years, or at the very least, think about replacing 50% of it with a fresh mix.
You should absolutely replace the mix in your containers if you detect that it has an illness or bug issues. The Miracle-Gro Indoor Potting Mix is a very well-liked blend, but I still believe that utilizing peat-free multipurpose compost is preferable and less harmful to the environment. (Keep in mind that potting mixes contain peat, which when mined releases carbon dioxide and methane.)
The peat-free multi-purpose compost is perfect for keeping your plants growing and vigorous, but you may want to think about buying sand to improve its aeration. Compost with good aeration and drainage is simply loam-based compost, but it contains peat, is scarce, and is challenging to locate one that adheres to good particle criteria. Potting mixes are made specifically for plants in pots, although they frequently include peat, the mining of which emits greenhouse gases, as well as other synthetic chemicals.
Can plants thrive in compost alone?
Compost combinations include abundant amounts of the elements magnesium, potassium, and nitrogen. This substance raises the question of whether we can grow plants using only compost because it enhances the quality of the soil and plants. Plants can grow in compost, but for a variety of reasons, some of them will just just make it through the process.
Compost is formed of organic material, whereas soil also contains minerals and rock fragments. Plants undoubtedly require both types of structures, but they are probably more likely to prosper in garden soil than in compost.
It can be challenging for plants to grow in an environment devoid of them because of their dependency on the minerals and rock fragments in the soil. But once more, it is surely alluring to put some plants in a pot and cover it with compost. After all, all the nutrients needed for growth are available right away.
However, the components of the compost serve a role.
when your flowers are exposed to an excess of the nutrients they provide plants, they can be deadly.
Even if a plant is grown using only compost and grows to maturity, there will still be obvious inadequacies. Because compost mixture consists primarily of decomposed organic waste, it drains quickly. For instance, when you leave a section of compost without soil support, it dries out.
This is useful since it enhances the drainage system when combined with garden soil.
On the other side, the plant will suffer as a result because its root won’t have access to enough moisture. The lack of soil in the compost mix causes it to dry out and dehydrate the plant.
Composting only plants is not recommended due to how easily the compost mixture compacts. Watering your plants is a necessary part of plant care, but topsoil-free compost will shrink more the more water you add.
How should compost be added to a potted plant?
Apply 1-2 1/2 inches of compost to the soil’s surface and work it thoroughly into the top 6 inches of the soil. Applying seed next, the surface is then raked. Using your measurement container, combine 19 containers of soil with one container of compost to achieve a 5 percent compost to soil mixture.
Does compost-based soil benefit plants?
Compost fosters the growth of healthier plants. The most well-known benefit of compost is that it helps plants grow strong and healthy. It encourages disease, pests, and weeds, regulates soil density, adds and keeps nutrients, and has a lot of additional advantages for plant growth.
Do I need to add compost to the soil?
Composting soil not only enriches soil for future years but also offers nutrients for plants today. The amendment decomposes spontaneously, liberating significant macro- and micronutrients and supplying food for the advantageous biological organisms in the soil. Additionally, it makes the soil more porous and aids in moisture retention.
What can I use for indoor plants instead of soil?
There are plenty of options for soil substitutes. Some people even create their own DIY soil using components like mulched paper and plant fibers.
Commercial soil replacements come in a range of materials, including moss, shredded bark, mushroom compost, vermiculite, sand, coir, nut husks, and animal manure, for those who want to keep their hands clean. Although these soil substitutes are far more environmentally friendly, they still need to be fertilized.
Can I grow indoor plants in garden soil?
Can indoor plants be grown in garden soil? Garden soil is not appropriate for indoor use. Natural soil may possibly cause insect, illness, and fungus issues in your home. Instead, potting mix should be used as mentioned above.
Can you combine garden soil and potting soil? Yes, adding some garden soil to your potting mix if it will be used outside is permissible (but not preferred) if you feel you don’t have enough potting soil. Your container will get heavier and more difficult to carry when filled with garden soil. Using wood chips, gravel, or leaves as a filler is a better option.
