Fabric grow bags are exactly what they sound like: plant-growing bags. Like a reusable grocery bag, they are composed of a strong, breathable fabric. Grow bags have better drainage than conventional plastic pots and are better aerated. The growing medium that is typically placed inside fabric grow bags can be any combination of soil, bark, wood chips, composted green waste, peat, or any other soilless material. Grow bags are adaptable enough to hold nearly any size plant because they are available in a variety of heights and widths. They may be readily rearranged as needed and are highly versatile. Other advantages of using grow bags include greater temperature and water control, as well as improved root systems.

Grow bags, also known as cloth pots, are generally used to cultivate a variety of crops and small to medium-sized trees. For any plant with modest root structures, they are perfect. Only watering is needed from the grower because nutrients, including nitrogen, are given to extend the growing season. When you have poor soil conditions or limited space, grow bags are the ideal answer. There are several brands available, and each has advantages and disadvantages of its own.

By arranging several grow bags side by side in a rectangle shape, you may use them to simulate an elevated flower bed. However, unlike conventional raised garden beds, cloth pots don't need to be built and can be reshaped as needed. It's easy to make last-minute changes to your arrangement; simply reposition your grow bags into the desired form. Your plants can be started indoors or outdoors, moved to accommodate different lighting conditions, and arranged however you see fit. When not in use, grow bags take up less room because they can be folded up and stored inside until needed.

An Overview of Grow Bags' History

Grow bags were initially produced in the 1970s for domestic usage, but they soon found use in more professional settings, such as market gardens.

Before fabric bags, in order to keep pests and illnesses from getting hold of the soil, the greenhouse soil needed to be either replaced or sterilized in between growing seasons. Growers in the commercial sector would need to disinfect and steam their soil. The plants were removed at the end of the season, and the compost was distributed over the outside borders.

For inexperienced gardeners or those with small gardens, this strategy was not practical. At this point, grow bags were developed to meet the needs of more novice gardeners.

Why Should You Garden With Grow Bags?

1.Better drainage

Grow bags offer better drainage and aeration because they are composed of breathable fabric. What sets them apart from most other garden pots is the aeration. The roots spread out until they touch the container walls in an environment without aeration. When this happens, the roots tell the plant to grow more roots, which makes the plant root-bound. The plant eventually suffocates itself by packing the container full of roots.

2.More robust plant roots

Grow bags don't cause root bounding. Rather, the roots are burned off as they get to the grow bag wall, which encourages the plant to grow new, healthy roots that branch off of the original ones. We call this "air-pruning." Plant roots in pots often grow in circles, entwining themselves. This makes oxygenation and water stagnation problems more likely, particularly in larger pots with improper drainage.

The roots of a plastic pot only start to round the pot when they reach its edge, where they keep growing in quest of more nutrients and water. This is when your plants' structural deterioration starts. Reduced uptake of water and nutrients results from the roots becoming restricted. Additionally, the compression of the stem will cause tissue damage in your plant, further limiting its ability to absorb nutrients.

The roots of the fabric pot sense the drier soil that is exposed to air when they meet the edges, which is why fabric grow bags help to alleviate this problem. They are aware that they have grown to this degree. The process of "air pruning" the roots is essential for producing healthy plants in containers. By doing this, girdling roots are eliminated due to root expansion.

When you air-prune, you will also receive a lot more fibrous roots. Plants with a more fibrous root system are able to absorb more water and nutrients. Nutrient uptake is restricted in plastic-potted plants because they encourage a few big roots to encircle and dominate the pot.

Plastic pots can get very hot in the summer and in direct sunlight. They trap all the heat that could cook your plants because they are not breathable. Because fabric bags are permeable, they help control temperature. Heat can leave the grow bag from all sides.

When not in use, where do you keep the pots? Do they end up as empty eyesores on the back porch or piled high in the shed during the winter months in the hopes that they won't be damaged or crushed? In the off-season, traditional pots will need to be piled for storage. Grow bags, however, take up very little room when rolled up and stored for the next season.


Grow bags are portable and easy to transport to new sites because they are lightweight and typically have handles built in. Because they are easy to transport from inside to outside and need little storage space, they are well-liked by RVers.

Advantages of Using Fabric Pots for Gardening

When it comes to grow bags and cloth pots, the advantages outweigh the disadvantages. Because fabric bags are made of breathable material, the previously described air pruning is possible. The roots are exposed to oxygen when they get to the fabric pot's sidewalls, which causes the last root to die. This permits your plant to produce new roots straight from the source.

The plant becomes stronger and may grow above the soil's surface more quickly with each new root that sprouts. The earlier this root system is developed, the more likely it is that the plant will retain its original root structure when it comes time to replant.

Compared to conventional plastic pots, grow bags are far superior at regulating the temperature and moisture level of your growing medium. The cloth will protect your plant from overheating by keeping it warmer in the winter and cooler in the summer. Fabric bags are porous, so they are less likely to retain excess water than the conventional plastic pot materials, even though they could require more frequent watering. When using cloth bags, the likelihood of root rot is extremely low.


One grow bag can support up to three plants. Just be sure to correctly prepare your planting bags and plant the appropriate plants in the right fabric pots.
