Why You Should Make Your Own

There are plenty of reasons to make your own grow bags rather than purchasing them from a store. For one, it’s more economical. You can reuse materials that would otherwise be destined for the trash, and you have complete control over the size and shape of your grow bag.

If you’re looking for a fun project to do with the kids, making grow bags is a great way to get them involved in gardening. Not only will they take pride in their handiwork, but they’ll also learn about the importance of taking care of plants. So go ahead and give it a try – you may be surprised at how easy and rewarding it is to make DIY grow bags!

What is the Best Fabric for Grow Bags?

When choosing a fabric grow bag material, look for something durable and breathable. A heavy-duty canvas or nylon will withstand repeated use and provide adequate drainage. For a more natural option, coco coir is a sustainable material made from coconut husks that is an excellent choice for growing plants. If you’re looking for something that will last longer, consider using polyethylene fabric. This synthetic material is UV resistant and will hold up well to the elements, making it a great option for outdoor gardens.

Here is a list of material that can be used as grow pot fabric. Depending upon your own environmental conditions, you can expect this material, when used as grow bag fabric, to last from 1 to 2 growing seasons (YMMV).

  • Felt – This fabric is made from recycled materials and has a porous structure that allows for good drainage. This is the fabric most commercially available grow bags are made from.
  • Burlap – A natural fabric that will allow air and water to pass through.
  • Coir – Made from coconut husks, Coir is a sustainable fabric that is perfect for growing plants.
  • Polyester – A synthetic fabric that is a good choice for outdoor gardens.
  • Landscape fabric – Made from polypropylene or polyethylene. Landscape fabric grow bags are durable and long-lasting.
  • Hemp – A durable fabric that is perfect for DIY grow bags.
  • Muslin – A lightweight fabric that will allow your plants to breathe and prevent them from overheating.
  • Recycled materials like old jeans or t-shirts.

Grow Bag Measurements

When deciding on the size of your grow bag, consider how much space you have and what you will be growing. If you’re tight on space, a smaller grow bag can be placed on a windowsill or countertop. For larger plants, a larger grow bag will give your plants room to root and grow. Keep in mind that the fabric you choose will also affect the size of your grow bag. A thicker fabric like canvas is best for larger bags, while a thinner fabric like muslin is perfect for making smaller bags.

Grow Bag Measurement Guidelines

Container sizes for plants
Adapted from Container Gardening
  • For small plants or herbs, use a grow bag that is up to 12 inches in diameter. Perfect for windowsills or countertops.
  • For larger plants, use a grow bag that is up to 24 inches in diameter.
  • If you have a large garden or want to grow multiple plants, use a grow bag that is up to 36 inches in diameter.
  • To determine the proper height of your grow bag, consider what you intend to grow. Vegetables have different root depths so you want to match the vegetable with a grow bag with the proper depth. Check out this vegetable root depth chart as a guide.

Best Methods for Making DIY Grow Bags

There are a few different methods that you can use to make DIY grow bags:

  1. Upcycle an old pillowcase or t-shirt. Simply fill the fabric with potting soil and compost, then sew or tie it shut. You can also repurpose an old pair of jeans by cutting them into long strips and tying them together to form a bag.
  2. Use burlap sacks, which can be found at many craft or fabric stores. Just fill the sack with soil and plants, then close it up with string or twine.
  3. Buy a roll of fabric from a fabric store. This is a great option if you want to make multiple grow bags at once. Just cut the fabric into squares or rectangles, then sew the sides together.
  4. Use fabric that you already have lying around the house. This will help reduce costs significantly.
  5. Look for deals on fabric at local fabric stores or online. You can often find great deals on high-quality fabric, which will make your DIY grow bags last even longer.

How to Sew Your Grow Bag

Making your own grow bags isn’t as hard as it may sound. All you need is a little bit of fabric and some basic sewing supplies. You can use any type of fabric, but we recommend using heavy-duty fabric like canvas or nylon. Start by cutting two pieces of fabric into squares or rectangles. Then, use a sewing machine or needle and thread to sew the two pieces together, leaving a small opening at one end. Next, turn the bag right side out and fill it with potting soil and compost. You’re ready to add plants or seeds!

Tips to Keep in Mind
