diaper crystals for plants

Diapers Help Your Plants Grow!

Introduction: Diapers Help Your Plants Grow!

Wait .. Diapers? How do those help your plants? Trust me, it’s probably not what you’re thinking.

Step 1: Watch the Video!

NOTE: The results, depictions and claims portrayed in this video are based on the limited experiences I had to test ideas prior to production. All information is believed to be true and correct at time of publication, and no information or results have been found to indicate otherwise. Individual results may vary depending on location and application. Use of video content is at own risk.

Step 2: Diaper Gel

For this project we’ll need one of these disposable diapers. New or gently used, it doesn’t really matter.

Now most people know that a diaper can hold quite a bit of liquid, but you might be surprised to see how much.

I tried putting over 4 cups of water in this thing, and you can see that in just a few seconds, all the fluid is completely absorbed, without a drop left in the bowl.

To see what’s inside, let’s go ahead and rip it open, and dump the contents into a bowl.

You can see that if we add a bit more water and mix it together, we’ve got ourselves an amazing, fiber rich hydrogel.

I tried packing some of this stuff into an airtight bag and freezing it overnight, to make an improvised ice pack that won’t leak.

Step 3: Super Soil

Now, you can use food coloring to change the color of the gels, but when working with plants it’s best to leave it clear. This way, your plants won’t turn funny colors as they grow.

One adult sized diaper makes over 12 cups of hydrogel, and the small pieces of cotton wadding break apart and mix right in.

Now we’re going to need some all purpose potting soil that you can get at any home improvement store, and a large mixing bowl to dump it in.

Add equal parts of dirt and gel, then begin working the two together until they’re thoroughly mixed.

Now you’ve not got a super absorbent, super soil that’s light and fluffy, and perfect for your potted plants.

Step 4: Potted Plants

In the event of an extreme overwatering like this, you might expect that your plants would drown, or begin to rot.

But with the hydrogels infused in the soil, you can see how the excess water is quickly absorbed, keeping the soil damp and fluffy, and possibly saving your plants as a result.

Now the reason this mixture will hold so much liquid is because of these super-absorbent water crystals.

They’ll hold over 500 times their weight in water, and if you want to separate them out, try ripping apart the wadding in the diaper, and shaking it upside down over a piece of paper. The cotton fluff should blow away, and you’ll be left with just the crystals.

Go ahead and throw a little soil into the pot first, then help your plant get comfortable.

To hold it firm in place, just keep packing more soil until everything sits tight.

You can finish up by giving the plant a bit more water, and now with the super crystals in your soil, your plant can go twice as long between waterings, saving you time, and resources.

This diaper gel can work on your existing plants as well. As the gel expands and contracts, it will naturally aerate the soil as it does.

Just grab a knife and a spoon, and gently nestle them down between the roots, and spread them apart to form a gap.

Now you can drop some gel down to the roots, work the soil back together, and continue around the pot until all your water-gel is used up.

Step 5: Seed Starters

If you’re looking for a lazy way to get your seeds started, just dump them into a batch of the grow dough, and give it all a good mix, or you could even just sprinkle the seeds on top.

Fill a container of your choice, add a bit of water, and find a place that you can set it and forget it.

Over the course of a week, your seeds will automatically sprout and begin to grow, without any extra effort, or any extra water.

For one final idea, you can help preserve your fresh cut flowers, by adding sugar, vinegar, and a bit of bleach to some warm water.

This will create a homemade flower food, and when you add your slush powder, you’ll see it absorbs the solution and slowly grows up to 60 times its size.

By agitating the gel you can create an awesome effect that looks like crushed ice.

Not only does it look cool, but it’s slowly releasing water as the flowers need it, and feeding them at the same time. The gel is completely non-toxic.

Step 6: Gardening

It’s biodegradable, and environmentally friendly, so it’s a great option for working into your garden.

Not only will this save you on watering costs, but it will also last quite a few seasons before it needs to be replaced.

Well now you know how to take an ordinary diaper, and convert it into an extraordinary super soil, that will help keep your plants happy, and hopefully keep you happy as well.

I’ve wondered how it would work to use diaper gel in houseplant soil & what the amount would be – may have to find someone with a baby, so I can try it!

I have to share my first experience with this stuff. My second child was born in 1986, around the time this stuff was showing up in diapers, but most of us didn’t know that, especially in the small town I lived in.

One day I was horrified to change his diaper & find this chunky, clear stuff all over his bottom & in every crack and crevasse. I didn’t know what it was, so I scraped it off & put it in a plastic bag, then took him to the doctor. The doctor didn’t know what it was either & was nearly as horrified as I was. He really gave my baby boy a good going over, but couldn’t find anything wrong with him. He told me to watch him carefully over the next few days to see if it happened again, in which case they might have to do further testing & he asked me to save the diaper if it happened, so they could do a urine test. He kept the plastic bag to ask other doctors if they had any ideas.

Thankfully, I didn’t see any sign of the stuff for about a week. Then one day there it was again! I took my son’s diaper off & he was covered with the stuff and his diaper was super soaked. After changing him, I went to put the diaper in a bag to save for the doctor, but accidently dropped it. When it hit the floor, it broke open & all that stuff fell out. At first, I was even more horrified, having no idea what it was!

Finally, I realized it must be part of the diaper, so I grabbed the box and read it. In small type, out of the way, there was a claim about “new extra absorbant gel”! When I called the doctor’s office to tell them what I’d discovered, they were grateful because they’d had other moms bringing their babies in with the same problem!

I know it sounds really dumb nowadays, but back then nobody had ever seen anything like it & there was really no publicity about it when it came out. The liners on the diapers weren’t very good at first & those diapers left a mess of gel on baby bottoms until they fixed the problem . Sorry this was so long, I just still find the story really humorous & thought I’d share it with all of you 😀

Why I Use Disposable Diapers In The Garden!

Did you know you can save time and money by using disposable diapers in the garden! They are not dangerous to your plants — The water storing crystals in diapers are the same stuff that is packaged and sold as garden watering crystals, only a lot less expensive.

When I lived in Kansas, it would get very hot in the summer. Our deck didn’t have any shade and some of my plants needed to be watered twice a day. I was going to buy the granules that hold water from the garden center, but I discovered small container of the water granules was $25!

Even though I really needed it to keep my plants going that summer, I just couldn’t come to bring myself to pay that much. One day, I was thinking about it as I was changing my son’s diaper. Then it dawned on me! The same stuff is in baby diapers.

I tore open the center of a diaper and scooped out all the cotton with the granules in it into a bowl. Out of curiosity I wanted to see just how much water it would hold. I was hoping for two cups. It held NINE cups of water! That means I could use this stuff in 3-5 containers of plants, depending on the size. I was able to get diapers for .20 each so the cost wasn’t huge.

Using disposable diapers in your garden or in container plants, you can save a LOT of time because you don’t have to water nearly as often and the plants have a more even supply of water. You can even use these for plants that are already planted as I demonstrate in our disposable diapers in the garden video!

You can even use used diapers (GASP!), but not dirty ones. If you have diapers that have only urine in them, they are fine to use in the garden if you’re willing to mess with them. Some people are horrified at the thought, but consider this:

Gardening is an outside activity. Squirrels, rodents, dogs and cats and other various animals pee in your garden all the time, but it just goes back into nature. I’m assuming your baby doesn’t have some hideous disease that would make their urine more dangerous for you or your plants than the urine from these animals.

Nature has a wonderful process of using chemistry to convert various substances to other completely different things so if you use manure, compost (rotted food), or something with baby urine, even to grow food plants, it’s not like you’re eating manure, rotten food and urine! Good grief!

We have had a question about the safety of using these in your garden pots. I personally don’t have a problem with it. I didn’t use these in my vegetable plants only flowers. Use your own judgment regarding whether or not you want to use them with vegetables.

If you’re curious about the safety of using disposable diapers, here are some details:

  • The external liner for some diapers is plastic. It will not hurt the soil and the plants won’t eat it, so you can use the diapers and later, when you’re re-doing your garden, you can simply throw the plastic away.
  • Diapers also contain the water storing crystals, which break down naturally and harmlessly over time (and are also sold specifically for gardening with different packaging).
  • Some diapers also have cotton or wood pulp, which decomposes naturally. Some people are concerned about how these item are processed when diapers are made, but there seems to be little substantiated concern and if you’re using them in the garden, the environment provides several layers of “buffer” that will convert them through chemistry as I mentioned above, so I’m confident any substance that might have posed a minuscule threat would be neutralized.
