Follow these simple instructions to get happier, healthier houseplants:
Step 2: Carefully poke a few holes into the soil’s surface (you might hit a few roots, but don’t worry about it).
Step 3: Thoroughly water your plant from the center outward, letting the water drain through the nursery pot’s bottom.
Will aerating the soil damage roots?
Worried that the journey may harm the roots? You may break a few roots in the process, but rest assured that this is nothing compared to damage that too compact soil may do.
Empty out any extra water from the bottom of any decorative pot in which your plants are displayed, and fluff up any soil toppers like moss or rocks. You should notice that your foliage has a more revived appearance within a few hours.
Should soil for indoor plants be aerated?
When I ran upon Darryl Cheng’s truly hypnotic time-lapse movies for the House Plant Journal, I first learnt about aerating plants. I was excited to learn something brand-new about caring for plants after seeing his video on plant aeration.
It just makes perfect sense. It doesn’t rain inside your house, so you water your plants, in Darryl’s own words. Because there are no worms in the soil of your house plants, you should occasionally aerate it. The makeup of the soil matters!
How can the soil around plants be aerated?
The majority of homeowners are aware that occasionally, their lawn may need to be aerated. Compacted grass soil can result from thatch buildup, family and pet foot traffic, and other factors. The soil’s capacity to contain oxygen decreases as it becomes more compacted. The vascular systems of the plant cannot operate correctly without oxygen, and their roots are unable to absorb water. Oxygen is necessary for the survival of soil-dwelling microbes and other creatures.
Lawn care professionals advise aerating the lawn when soil compaction is a problem. A spike aerator or a plug aerator is typically used to aerate the soil. The soil is cleared of genuine cylindrical plugs with a plug aerator. A spike aerator uses a spike to make holes in the ground. Because employing spikes to pierce the soil may result in increased soil compaction, the majority of lawn specialists advise using plug aeration.
How should compacted soil be handled in houseplants?
The pace of ventilation, waterflow, and nutrient flow to a plant can be stopped when the potting soil of an indoor plant hardens, clumps, and becomes immovable. Instead of simply repotting the plant and discarding the hardened potting soil if you have compacted soil in a potted plant, how can you loosen the dirt and revive it? What are some quick ways to aerate and loosen soil that has been compacted around potted plants?
Here are some quick methods for breaking up compacted soil in potted plants:
- Break up the soil using a chopstick (or other similar object).
- Peat moss and perlite are good aerating ingredients to include.
- Use live earthworms while making vermicompost.
In this comprehensive explanation, I’ll first go through the causes of soil compaction and why it harms plants. I’ll then go into detail on how to carry out each of the aforementioned soil aeration techniques. You’ll get more out of your soil if you aerate it, so don’t miss this opportunity!
How may compacted soil be avoided in houseplants?
Have you ever observed that when you water your plant, the water seems to pool on the soil’s top rather than soak in? or that the dirt seems to be dense and hard? It’s time to show a little affection to your plant. A major problem with indoor potted plants is compacted soil, which makes it difficult for small animals like bugs, worms, and microorganisms to survive.
Without the natural aeration that these organisms provide, the isolated soil inside your plant’s pot would inevitably become dense over time. It is our responsibility to ensure that the soil provides the right amount of nutrients, water, and oxygen to our houseplants. In order to effectively address the issue, it’s crucial to first comprehend why soil becomes compacted.
Why soil becomes compacted in plants For a variety of causes, the soil in your plant’s pot may be compacted. The most typical ones are:
- an outdated soil. Even if the dirt in your houseplant may not contain any pests or mold, that doesn’t necessarily mean it’s good for the plant. Both the small quantity of soil inside a container and the fertilizer and aerating components present in potting mix aren’t meant to survive indefinitely. Fast-growing plants typically need their soil replaced every year, although slow-growing plants, like the Snake Plant, can go longer.
- It’s the incorrect kind of soil. The fact that using topsoil or dirt from the backyard is hazardous for your indoor plants shouldn’t come as a surprise. These soil types have objectives beyond than giving a potted plant the right balance of nutrients and air. To provide the ideal growing environment for houseplants and succulents, potting soil is offered for a wide variety of plant species.
- The soil is too wet. In some cases, plants that receive excessive amounts of water frequently develop compacted soil. By flushing away the necessary aerating ingredients, top watering a plant might result in hard, dense soil. Each fresh watering will cause the remaining dirt to sink more into the pot. Bottom watering is a practical solution to this problem that also gives plants a more complete watering.
The issues caused by compacted soil The effects of compacted soil on your potted plants may now be a little clearer. Your plant may be significantly impacted by dense soil, which also raises the possibility of it becoming ill or even dying. In the first place, soil compaction can cause a reduction in water flow. When you water your plants frequently yet they still appear parched or yellowed, it’s because the water can’t get to the roots adequately through the soil.
Similar to underwatering, overwatering will quickly saturate your plant and fill any spaces between soil clumps with water. It is challenging for the roots of your plant to absorb the necessary oxygen in this moist soil. Additionally, the soil gets denser and more compact with each successive watering.
Another frequent result of soil compaction is a lack of nutrients. After the initial repotting, the nutrients and fertilizer in new potting soil won’t survive longer than a few months. With each watering, they can be flushed out and lose their effectiveness. Alternatively, if fertilizer is applied to the soil’s surface, it might not be able to penetrate all the way to the roots of the plant because the soil is too compacted.
Compacted soil also hinders the growth of roots. Growing plants prefer to spread their roots out, but when the soil is too compact, this becomes challenging. It is also challenging for air to dry out the soil and supply oxygen to the roots when the soil is both compacted and moist. Root rot frequently arises from this!
How to enhance soil aeration and loosen compacted soil Two easy methods—neither of which requires much effort—can help break up tight dirt.
Technique 1: Gently puncture holes in the soil of your plant with a chopstick. Wherever you believe there are the most roots, try to dig a tunnel there. Try not to push a hole; there can be some resistance, depending on how dense the roots are. Water your plant after making many holes in the soil, being sure to avoid covering the holes. Water and air will be able to travel where they need to with the help of this area!
Technique 2: Depending on the kind of plants you have, mix up a new batch of potting soil, aerating components (such peat moss, vermiculite, or perlite), and perhaps even sand. Both the right nutrients from the additional soil and the proper aeration from the extra materials will be present in this new mixture. Your plant should be completely de-soiled before being re-potted into this new soil mixture and well-watered. Your plant’s color and growth should both noticeably change.

How can I get more oxygen to the roots of my plants?
Good plant development can be achieved by aerating the soil or media, and frequent maintenance of the soil and growing medium enables the roots to absorb essential oxygen. Similar to this, growth media are chosen according to their degree of porosity. Plants that are healthier clearly show the effects. This information can be used to grow under cover, whether you’re hydroponically growing plants in water or in peat-based materials.
Kurt Becker, director of commercial goods sales and marketing at Dramm, claims that the temperature and salinity of the water have an impact on the amount of dissolved oxygen (DO), which is calculated in mg/l as a percentage of saturation or in parts per million. Compared to warm water, cold water has more dissolved oxygen. Additionally, clean water has a higher potential to hold dissolved oxygen than subpar water that contains unwanted minerals and other impurities from irrigation systems or the source, such as a pond or reservoir.
A dissolved oxygen meter can be used by growers to gauge the oxygen levels in substrates, hydroponic systems, and irrigation systems. The amount of oxygen that reaches plants will rise thanks to technology that is being developed by a number of firms at different price ranges. This technology may be the key to greater root development and the avoidance of illnesses like Pythium.
Hydroponics vs. container production
“According to Dr. Paul R. Fisher, professor and extension specialist in floriculture at the University of Florida, there are two different scenarios. The first is growing in a container with peat or coir substrate. “We selected those substrates because they have lots of air holes. Air carries oxygen considerably more quickly than water does. Focus on not overwatering and making sure your growing medium has enough air porosity to provide your roots oxygen if you’re a tomato grower growing in pots.
Hydroponics is the other growing environment, according to Fisher. “According to him, it is crucial that there be adequate oxygen dissolved in the water in hydroponics, where the roots are submerged in water. Only then will the roots be able to obtain oxygen for healthy growth and respiration.
“According to him, the oxygen content in water should be kept as close as possible to the water’s natural saturation point, which is somewhere between eight and nine parts per liter, while using hydroponics.
Warm water is used by growers while using hydroponics. Warm water doesn’t store as much oxygen as cooler water does, and root and bacterial respiration happens more quickly, according to Fisher. Low oxygen levels have been discovered to increase the likelihood that infections like Pythium would begin to harm roots, according to plant pathologists.
Paying attention to dissolved oxygen
According to Becker, “We observed instances where consumers were experiencing growth challenges but had nothing to blame; they just had troubles. It came out that they frequently had extremely low levels of dissolved oxygen in their water, despite no one being aware of it.
Becker compares electrical conductivity (EC) in the soil, which growers first became aware of 50 years ago, to DO. “We were aware that fertilizer would aid in the plant’s growth. However, he claims that increasing EC has significantly increased plant productivity.
The same is true with pH. A healthier plant will come from adjusting the pH to the proper level since nutrients will be absorbed more effectively. If you measure the dissolved oxygen in your water and make the required adjustments, according to Becker, identical benefits will take place.
“According to Becker, we now realize that dissolved oxygen is the third measurement that nobody has been paying attention to.
According to Becker, many farmers are ignorant of the amount of oxygen in their irrigation water or that increasing the oxygen content may result in plants with stronger roots.
“Education is still necessary, according to Becker. “Many people have trouble understanding it. It is understood by those who grow in water, by those who use hydroponic baths, and by those who grow cut flowers.
According to Becker, plants may grow slower and have less cation exchange when oxygen levels are low, which is very frequent among growers.
Improving root growth through electrolysis
Plants’ root zones can receive oxygen through relatively affordable oxidation systems, which may result in an increase in root mass and better growth. This idea was tested in a university study utilizing technology from the company O2 Grow, which uses the electrolysis process to give irrigation water 100% oxygen. The O2 Grow system injects microscopic oxygen and hydrogen molecules that swiftly dissolve into the water, as opposed to an air bubble system that creates big air bubbles that rise to the surface and escape.
According to Dr. Sonja Maki, an assistant professor in the Department of Plant and Earth Sciences at the University of Wisconsin-River Falls, “We had been finding inadequate root development in two of our hydroponic setups. “We observed the DO was relatively low at 5mg/l when trying to boost plant growth in a vertical greenwall and an NFT system. We attempted to add air stones, but it didn’t really help.
Crown peas cultivated in an NFT system in a greenhouse were the subject of an experiment, according to Maki, which she conducted with Taylor North, an undergraduate student. We decided on the crown pea since it is a determinate plant that also has a large top and lots of flowers, she explains. The O2 Grow technology was used in studies, and the results showed a noticeable difference in the growth of the experimental plants compared to the control group.
“The important takeaway is that we saw taller plants and improved root growth after we planted the crown pea in the experimental group. With the oxygen, Maki claims, they also dramatically increased their branching. She claims that the plants in the experimental group had longer roots and better weight than those in the control group, whose roots were “brownish and the lateral roots terminated prematurely.” She claims that they were able to achieve roughly 8 mg/l of DO in the water the plants were growing in using a three-in-one meter that also detects pH and EC. She admitted that there are alternative approaches to raising the DO in the water. However, this strategy provided a somewhat inexpensive way to enhance a plant’s root system and overall growth.
I’d recommend they might want to give it a try if they’re curious to learn how it would improve root health, Maki adds. ” I’m only using one cultivar, which is not a commercial variety. They might wish to test it out on their current cultivars.
Ozone in water
When included into an irrigation system, ozone (O3) is a strong and effective oxidant. By oxidizing organic matter and biofilm in the water, it keeps the pipes clean. What’s the connection to dissolved oxygen? Higher levels of DO are maintained because clean pipes use less oxygen. The fact that ozone is 13 times more soluble in water than O2 is more significant for growers since it enables higher levels of oxygen to be dissolved in water. According to Becker, including O3 into an irrigation system will sustain higher concentrations of dissolved oxygen.
To sum up, increasing dissolved oxygen and ozone may be the key to faster cropping and improved root development. Although meters are not very expensive, the equipment to transport these gases, especially ozone, can be. The cost of each unit must be considered by growers in order to choose the ones that will provide the best return on investment for their business.
