Can baumbad tree bags be repaired? Yes! And the more the better!

We therefore ask you not to simply dispose of the watering bags. In addition to the repair, there is also a recycling program for damaged bags. In this your bags will be repaired and donated by us, or the bags will be closed repair kits processed, which we make available to you free of charge if you want to repair your bags yourself.

That is exactly why we have prepared the following instructions. The tree bath bags can be repaired as they are made from a resilient PVC material which is also fiber reinforced for use with trees. PVC is also used in inflatable boats and many inflatable playmates for swimming pools or bathing lakes are also made from a similar material. As a result, there are numerous glues and repair kits that you may even find at home.

In our repair instructions, we have tested a wide variety of household glues, materials and repair kits (mostly for inflatable boats, as they are also made of PVC) in order to keep it as simple and environmentally friendly as possible. If you don't find anything at home, we have also included a list with our recommendations at the end. These can be purchased at many discount stores, hardware stores, or online. In this way, WE can save as many bags as possible and save resources together!

The photo shows the different glues and repair kits that we tested for repairing a tree bag.

Given the multitude of options, we want to tell you about our experience with repairs and show you what was particularly suitable and what we cannot recommend. We also recommend that you first read the instructions completely, as there are a number of things to consider and only then use the instructions to start the repair.

8 ways to fix a tree bag.

We once searched our home and the internet looking for products that might be able to fix a tree pouch. The idea came from the fact that this gives you the opportunity to see whether you already have something at home and not have to buy something new to repair your broken tree bag. We came across the following 8 repair options. The prices for the individual options are between €0,99 and €19,99. We are aware that for the price of some of the sets it is possible to buy a new bag. But that's not exactly what it's about. We want to work with you to repair as many tree bags as possible! If you already find something to repair at home, this would be the ideal case for repairing your defective bag in a resource-saving and environmentally friendly manner.

  1. superglue - (about 1€)
  2. M3 duct tape / fabric tape - (about 2€)
  3. Liquid PVC glue (Liquid PVC) - (about 11€)
  4. vulcanizing glue (tent and tarpaulin repair kit) - (about 17€)
  5. Two component adhesive (AB adhesive) - (about 2€)
  6. Inflatable boat PVC repair kit - (about 20€)
  7. Repair kit for inflatable rubber toys - (about 13€)
  8. PVC tape - (about 17€)

It is also useful to use the following tools:

  • Gloves
  • emery/sandpaper
  • Brush (for spreading the glue - included in many sets)

Spoiled for choice! What is the best way to repair a tree bag?

First we have our tests on the famous M3 duct tape (tissue tape) thought. My grandfather used it to repair all sorts of things. You might also remember the silver tape.
Unfortunately, we were not able to apply enough adhesive strength to hold back the water. It always found a way out of the bag at various points on the tape. This can also be due to the pressure with which the water pushes in the bag. Therefore, the M3 tape is not suitable for us to repair tree bags.

Next, we took a close look at the various repair kits. These usually consist of an adhesive and various patches as well as gloves or other tools for applying the adhesive. The material of the repair patches from most repair kits is very different from the material of the tree bags. It has been shown that the fiber reinforced PVC material of the tree bath watering bags does not work so well with the PVC for inflatable boat or inflatable toy harmonizes.
This is because inflatable boats use a PVC that is significantly thicker than the tree bags. Inflatable boats or rafting boats have to endure a lot when they race over stones and other obstacles in the river. Also, boats are always about human lives, which means that very thick and stiff material is used.
In inflatable toys, the processed PVC is much thinner and softer than in the tree bags. After all, it should be as light as possible and easy to transport, even for children.
As a result, the materials differ so much overall that the repair kits don't stick to the tree bags.

What didn't work to fix the bags:

In PVC tapes and the M3 armored tape didn't last. Not even in larger quantities. Therefore, we cannot recommend them for repair.

We can't recommend either the patches from the repair kits to use for boats or inflatable toys to fix a tree bag.

Here is a video where you can see how the different glues and materials stick to the tree bag.

What worked to fix the pouches:

All other tests have shown that the recycled patches (i.e. patches made from the same material as the baumbad tree bags) hold best and stay tight, regardless of which adhesive was used in the test.
Should you PVC glue, instant glue, 2-component glue, vulcanizing glue or similar glue that can stick plastic, nothing should stand in the way of a successful repair.

To make it even easier for you, we have documented the repair with liquid glue step by step for you and summarized useful tips for you.

Step-by-step instructions for tree bag repair using liquid glue and patches:

The repair process was similar for the different adhesives. In this example we used superglue and a piece of PVC patch from the recycling program.
The use of the patches is particularly recommended for damage such as cuts or holes in the middle area of ​​the tree bag. A repair to the outer weld seams is initially not considered here.
We always used gloves when handling the glues to protect our skin. You should also always read the associated instructions for use before using adhesives. This always includes the drying times and safety instructions.

Important: Before repairing, the area of ​​the tree bag to be repaired must be thoroughly cleaned. This must be free of dust and grease so that the liquid adhesive can adhere well.

Overview of the work steps:

  1. roughen the bag
  2. edit patches
  3. apply glue
  4. Bring patches and pouch together
  5. let dry

Overview of the work steps when repairing with a liquid adhesive and a patch.

Repairing tree bags with liquid glue with useful tips in detail:

Step 1 - Prepare the repair site

First, the area to be repaired is thoroughly cleaned and then the surface for the patch to be glued is roughened.

Damage from a cut can be seen. We cleaned the bag 2-4 cm around this and then roughened it with sandpaper (80-200 grit). It is important to only remove a small amount of material so that the bag is not further damaged.
Tip: Roughen the tree bag slightly and the patch more heavily. This also prevents further tearing. The roughened area should be larger than the patch used.

Step 2 - Selecting/cutting the patch

In the second step, a suitable patch is selected or cut and also roughened.

After preparing the pouch, a suitable patch is cut or selected. The patch should be larger than the damage. A patch size of 2-4 cm around the cut is ideal so that there is enough space for the glue all around and sufficient support is generated. In the direction of the cut, this can also be a few centimeters more.
Tip: It is important that the patch does not become too large around the damage, otherwise the bag will be more difficult to seal.

Step 3 - Apply glue

Next, the glue is applied according to the instructions for the glue.

Now the superglue is applied. Depending on which liquid adhesive is used, there are various things to consider. At the bottom of the article we have also compiled the advantages and disadvantages as well as tips for other liquid glues for you. It is important to distribute the adhesive generously and neatly over the entire patch. Do not use too little glue, otherwise a leak may occur.
Tip: Superglues have the property that they harden in a very short time, but do not work in a hurry, they also need a certain amount of pressure to start the process.

Step 4 - Applying the patch

In step 4, the patch is applied over the damaged area.

Now the patch is pressed onto the bag. You can use your finger to spread the glue from the inside out so that the glue is spread over the entire surface. If the glue runs out, that's okay (just leave it there). Better a little more glue than too little. Be careful with your fingers though, some glue can become sticky very quickly.
Tip: The bag should be on a smooth surface. In addition, work quietly and calmly, then the result will be dense and you will keep your fingers clean.

Step 5 - Let it dry

Now it's time to wait and let the glue dry.

The last step is curing, the drying time varies depending on the glue. It is best to refer to the operating instructions for your adhesive. If you distributed and pressed the glue well in step 4, most glues no longer require constant pressure.
Tip: To be on the safe side, you can always wait a day before putting the bags around your tree again. Don't just put something heavy on the patch, otherwise the item could get stuck too!

Why does it happen that tree bags need repairs?

In daily use, there are a wide variety of things that happen to the tree that can have an impact on the lifespan of a tree bag. We have therefore listed the most common influences for you:

  • improper handling (see instructions) with the pouch
  • Damage from hedge trimmers
  • Lawnmower or robotic lawnmower
  • Vandalism
  • Winter services sweeping snow
  • Rodents, martens or other wild animals (usually only when it is very, very dry and they can no longer find drinking water).
  • Weather influences such as storm, hail, frost or the sun (our bag has UV protection)
  • Dogs that pee on him for a very long time
  • Algae can clog the two holes after a long period of use
  • Dirty water or impurities in the bag could clog the holes
  • Fertilizer additives (depending on chemical composition)

Tips for a long life

It is best to only use the bags in the phases in which they are needed and in the remaining time put them in a dry place, dried and cleaned, so that no algae form and the bag is protected. If possible, also avoid the circumstances listed above that reduce the service life. Then your tree bags will remain fully functional for a long time.

Conclusion on the topic of repairing tree bags yourself:

We hope this post will help you to repair your tree bag yourself. It has been shown that it does not take much to repair the tree bags if they have been damaged. Most of us even have everything at home for a repair.
That's why we should all take advantage of the opportunity to repair before a bag is just thrown away.
If you still prefer to buy a new tree bag instead of repairing the defect, we would like to ask you to support us in our recycling program so that we can repair and donate the defective bags or process them into repair patches. Defective bags are also valuable resources. Let's not waste them.

We really enjoyed combining the different materials to find out what works. We also learned a lot about our products. We incorporate this knowledge into the newer generations of tree bags in order to make them even more durable and resistant to environmental influences. We are a young start-up that is constantly training and learning. If you come across a solution during your repairs that we have not tested or have additions, we would be happy if you share them with us and the #baumretter community. In this way, resources can be saved and trees can be optimally watered.
