Air Pruning Explained – Hon&Guan

Air Pruning Explained

Air pruning happens when roots are exposed to the air and in the condition when there isn't a lot of humidity. The roots are effectively "burned and destroyed" This causes the plant to keep making new, healthy branches of roots, roots grow around a container in a limited way if they don't get enough air.

The root structure of plants grown in regular plastic and ceramic plant pots is one of the most common issues that gardeners encounter. There's a risk that the roots of plants that are in traditional pots will get too crowded. They get all tangled up and, in some cases, end up killing the plant above ground.

After a couple of months in a conventional plastic plant pot, you'll be able to see what we're talking about if you pull a plant out of it. You're going to find a lot of long roots that have twisted and turned inside the pot, and they're probably dripping with water as well. This is because traditional plastic containers don't let plants drain excess water away properly.

The Benefits of Air Root Pruning

It's called "Air Pruning" and it's used by Proptek containers to get these great results, with that said these include:

  1. There are no chemicals, and there is no toxicity.
  2. It's cheap because the method is built into the pot.
  3. Astonishing results were achieved.
  4. Versatile: can be used in many different ways and can be changed to meet the needs of any nursery.

Almost every plant can benefit from air pruning. The number of roots and the way they grow are different for each species, but air pruning can help all plants. My experience in the field has led me to believe that all plants will benefit from air-pruning. There may be species I don't know about.

Air pruning is also good for plants that are going to stay in their pot for a long time. Because the plant has been air-pruned, it won't have root circling, which means you can keep it in the container for a longer time. This will make the plant healthier. The plant will eventually need to be moved to a bigger aeration container, but the length of time it can stay in the aeration container as opposed to a container that encourages root circling is much longer. This gives you more time to enjoy your plants before moving them.


To make a cheap and sturdy bench, you'll need to build a wooden frame and cover it with wire mesh. The exact dimensions of each table should be different based on what you need. There are two 16" cinder blocks and a 16" piece of the 1-inch by 4-inch treated lumber that make up the base of this bench.

  1. Place the bottom cinder block on the floor, facing down on the ground.
  2. Place the second cinder block vertically in the middle of the first one, on top of the first one.
  3. Lay the 16" piece of wood across the upper block.
  4. Place these legs 4' apart on each side of the bench. The frame will rest on them.

If you have a lot of space, the frame should be 4 feet deep. It can be as long as you need it to be. For a simple frame, 2-inch by 4-inch treated lumber should be used. Then, the mesh metal surface is put on top.

The height of the bench can be changed by adding more horizontal cinder blocks to the top of the bench. This will make a bench that is at least 16-24 inches tall.

The growth of air pruning

An air-pruning propagation system is a cheap and efficient way to grow cuttings, seedlings, or container plants for restoration projects. It is also easy to use. Air pruning usually takes place by the time of roots exposure to the air when there isn't a lot of humidity. The roots got completely burned. This causes the plant to keep making new, healthy branches of roots. roots grow around a container in a limited way if they don't get enough air.

There are many ways that the roots can spiral, twist, kink, or become coiled. When the plant is later put in, it is likely that it won't be able to grow a normal root structure. Instead, it will be able to get less water and nutrients. At some point, the plant will look like it's growing in the wrong way, which could make the plant die. It can also cause leaves to turn yellow or brown, shrivel, or fall off when the root system isn't strong enough. Healthy, well-branched root structures help a plant get water and nutrients more quickly and efficiently, which leads to more growth and better plant health. People who work on restoration projects should make sure that plants have strong roots so that they can grow.

How do you get the most out of an air-pruning bench?

A hoop house or greenhouse could be used for the benches based on the weather and the plants. In a closed space, more attention must be paid to humidity and air flow.

It's best to water plants from the top, either by hand, with a drip irrigation system, or with a mist system. When you are growing cuttings or seedlings, a mist irrigation system may be the best way to do it. The misting system can be built with irrigation supplies from your local hardware store, or you can buy a kit from many online retailers.

Seeds or cuttings should be grown in plugs or plant bands. This way, they can be grown. Plant bands are open-bottomed paper sleeves that are very good to use. Roots can be air-pruned from below, and the paper will break down when it is planted. Plugs may not be very good because they need a lot of places for air to get to the roots, including side slits. If there is any air contact on the side of the plant bands or plugs, it will help to cut the lateral roots back. It can also be hard to get plant material out of plug trays because they are so small.

It is important to use a soil mix that can hold a lot of water because of the large root structure and the tendency of plant bands to dry out. There should be no drainage problems because the bench is suspended above the ground. This is a good thing.

Air pruning is also extremely beneficial at growing trees. It extends the "life" of the plant material, stops root circling, and makes plant installations more successful because the plants grow quickly after being moved. People who use these systems don't have to change the pots as the trees get bigger, because small plants can be put right into big pots.

 When you put a plant in this type of pot, it grows a dense root ball filled with tiny white roots that are ready to branch out when you put it in the ground. Roots may also be more resistant to very hot or cold weather, too. This can help a lot with the survival rate of plants that are put in as part of a restoration project.

Frequently Asked Questions

Q. How do air pruning pots work?

Air pruning pots are used to cut down on the amount of air that gets into the plants.

There are slots or holes in the walls of an air pruning container, and there are ribs or other things that make the root grow out of the slot or hole. This makes it easier for it to get out. In dry air, the tip of the root is "dead" or "killed."

Q. Is it possible to use Air pots with soil?

You can put Smart Pots filled with soil into ebb and flow systems to make sure your plants get enough water. It's also possible to fill them with coco coir and use them in large hydroponic systems.

Q. How do you know the roots are air-pruning properly?

There is a way to tell if the roots are air-pruning well.

  1. It is preferable if no roots can be seen outside the container or beneath the lid. If you can see white tips on the roots, try:
  2. Using fans to help move the air
  3. putting up the bench
  4. cutting down on the humidity (increase ventilation)

The coolest thing about air pruning is that it lets you cut things like trees and shrubs. As the new little roots spread through the soil, they can get more nutrition and more water to drink. It takes a lot more than one long, single root in a plastic container to get rid of all of the waste. Happier and healthier plants are the result. They have all the things they need to grow bigger, stronger, and faster. This is great news for farmers or commercial gardeners, because it means more crops will be grown.
