Straw bale raised bed

Hi everybody,
New here. I just wanted to share something I just found in a book. To save a ton of space in your garden or raised beds.......plant pumpkin, squash, zuccini, etc by doing the following:
set a bail of staw on the ground, cut side up, and soak it with water for a couple of days. Punch two holes in the top about the size of your fist, 4 or so inche deep. Make them 2' appart. Fill the indentations with a good mix of compost. Now plant your seeds in the dirt and you have an instant raised bed squash garden.

it sure could work, but in our area straw is just NOT available..and hay is full of seeds and going for an extreme price this year

Is it really as easy as this to make a straw bale garden? What are the possible downsides? Does it work for other crops than the squash family?

I wonder if the book the OP referred to is “Straw Bale Gardens" by Joel Karsten?

It's basically that easy. In my experience you have to feed a lot.

When I had a place with a big garden i would regularly go pick up straw and hay that had gotten wet and moldy to use for composting and mulch and I did a couple raised beds from those.

If you have basically free bales and no other use for them it's a way to use them while they start to compost

I've grown potatoes and squash and kale and tomatoes in rotting hay-bales. The yield for me has always been lower than planting in good garden soil, but still worth doing. And you can use the bales to occult the grass and weeds from the sun for a year and then once the bales sag/break down too much to use them that way, they're a source of mulch right where you need it. (I can't get straw that I trust, but I do have a source for unsprayed hay, which is full of weeds, but so's my land.)

I have used straw bales and straw for about 15 years in raised beds. The main problem is finding a good source that is cheap.  A second issue is they take a good deal of water initially. I try to get them out in the fall. That way they take in the winter and spring rains. I apply manure on top between rains. Once they  are thoroughly soaked, they need minimal water afterward.  Before I plant, I spread a layer of soil across the top… or just in the holes described above …depending upon the crop.

I find them to be fantastic for tomatoes. … 2 plants per bale is best for me.  Beets, onions, and carrots also do well in bales.  I plant as many as I can rationally fit.  Potatoes do well in bales, but I tend to use loose straw for them that has seen use in the stalls.

Works for tomatoes and peppers too, not just squash. I tried it a couple of years back and the main thing is you really do need to keep on top of feeding, the bales just eat through nutrients. The upside is once they break down you've got a nice patch of soil underneath where the grass was, so even if the yields aren't amazing that first year you're building something for the next one.

I think this is one of the most attractive parts for me - a really easy way of preparing ground for next year, as well as getting some sort of crop this year.
I think it could work really well in my damp climate, but I suspect in a dry/hot one keeping the bales watered might be more of an issue. Would deep watering with leaky bottles be sufficient perhaps?

If dealing with a dry climate, my first question would be if there is a wet season. If so, I would set out the bales for that. From my experience, it is important that they be thoroughly saturated before planting. When that rains stopped, I would mulch …maybe with dumpster procured plastic.

Edit:  …and, rather than a raised bed, it might be better to sink the bale in the ground.

I think this is a neat idea if you can get organic straw.  A lot of wheat is grown with persistent herbicides and that can really diminish the health of your soil and garden plants.

While not as effective as straw in retaining water, hay can be used.   Anyone who has tried to move a wet bale of hay can support its water holding abilities.   In my area, farmers are not so quick to use chemicals on the hay fields.  There is a secondary risk in that manure from animals who have been exposed to chemicals may have been used.  also there is the question if crop rotation and the last time chemicals were used on the field.  In my area, it is a safe bet that it has been at least 2 years since there has been any exposure to chemicals for hay.   In one case, I am certain the figure is more like 25 years …. Not due to organic philosophy…but due to not wanting to spend the money.

Several years ago I tried my hand at strawbale gardening.  If I remember correctly, I used bloodmeal, a little bit of bonemeal and composted manure as sources of nitrogen to start the decomposition.  I also planted in little fertile holes filled with that same composted manure.  

The strawbales did indeed break down as long as I kept watering them which was easy enough to do--until we left for about a week.

When I came back, it was obvious that the plants were suffering from heat stress.  The bales did break down significantly and what did not break down that year simply became organic matter that I raked onto the soil of my garden beds.

Honestly, this is something that I would consider doing again.

I wonder if you could pee on the bales to supply nutrients and moisture at the same time, for free?

On the other hand I provided a pee-bale to a wwoofer once and it stunk to high heaven so maybe it's not such a good idea...

Pee is the only fertilizer I add to my haybale gardens. I wonder if adding more nutrients of whatever type would boost my yield and whether there's anything I'd be willing to add.

Hi Eric,

I am surprised you had water problems in a week. I am wondering if the bales were thoroughly saturated.  Of course, water might have had little to do with heat stress.

Hi John,

It was July--HOT!  And I might not have had the bale properly saturated.

But that's OK, it was a fun project anyways.  And when the season was done, all that composted straw was a good amendment to add to the garden.

This came at a welcome time. I was just debating making a lasagna style garden plot with layers of composted manure and straw. I have heard about straw bale gardening, but never knew anyone who did it. The issue I have is that I live in Georgia which means extreme heat. Does anyone have experience with this method in hot weather? If I could forgo the manure and just use the bales that would save me some significant money on startup.

Hi Richard,

The straw bales could be a very good option for you.  And yes, the heat is a real issue, but it is something you can overcome, especially if you can keep moisture on it.

For conditioning, although I used blood and bone meal, you might get better results by peeing on it.  And its cheaper too.  Urine is an excellent fertilizer, but it can be a bit hot.  If you can get the urine to start breaking down the straw, you can mitigate this problem.

That said, I would still work in some manure if you can do it.  My reasoning is that the bacteria from the manure will happily add to the microbe party taking place in the strawbale.  They will probably make it break down faster as well.  When I use the manure, I worked in in on the sides and especially in between the bales.  Basically I was trying to get microbial action going everywhere I could.

Regardless of how you get the nitrogen on the bales, they will break down--surprisingly quick.  I doubt that they could survive to work another season, though you could use them as a base on which to set new, fresh bales.  This would add yet more microbial activity to the new bales.

But for my purposes, I like just add this decomposed straw to the garden bed as a sort of mulch--and a very fertile one at that!



Good luck on your project, please let us know how it works out!



Eric

Thanks Eric! I was planning to use manure to fill the holes I was placing the plants inside of. I will try the urine thing although may wife may think I'm insane. How saturated are we talking when it comes to watering the bales?

I think a manure tea/smoothy might help the strawbales break down.

Alternatively,a slurry of common garden soil, followed with a planting of inoculated legumes?
Would the legumes and the nitrogen fixing bacteria be able to set up shop?

What about a green smoothie made up of weeds?
Could that provide the needed nitrogen?

King stropharia spawn added to the bales should help break them down while providing another yield.
If the bale is placed on top of a bed if wood chips, you are liable to inoculate them during the life of the bale.
Such a bed would also hold a lot of water.

Richard,

I would really soak those bales, but something you will likely find is that the bales can only get so wet.  One of the beauties of the bale system is that it is hard to overwater—the extra just runs out onto the ground.  

I like your thoughts about using manure as it is pretty much exactly what I was thinking.

William also has really good points about making a slurry to aid breakdown.  But even better is the use of Stropharia mushrooms.  If you decide to go with Stropharia, make no mistake, those bales will be not just decomposed but utterly destroyed (by appearance).  The resulting material will be superb gardening material,


So far I think you are off to a great start!

I was given a bunch of moldy hay bales and used them in four foot tall raised beds. Bales taking up the first sixteen inches saved a ton of dirt. The bales did degrade over the years and I did have to add to the beds as the hay composted, but when looking at the dirt that was the result of the bales composting it was beautiful and filled with worms. The composting of the bales probably gave off some heat as they changed, but I didn't think about taking any temps.

That’s what you want!!

If you get plenty of nitrogen in the bales along with plenty of moisture, you’ll have a good set of decomposing bedding by the end of the season.

I had another thought for you—coffee grounds.  If you can get ahold of used coffee grounds and work them in and in between the bales, you have one of the best-perfect items to really start decomposition.  They have about the perfect balance of nitrogen, oxygen, carbon and water.

And while this shouldn’t be a problem, just make certain you get a good supply of microbes.  If you have any doubt, just find the most fertile place on your property and dig up a few handfuls.  That should be sufficient to get microbes in place to do their jobs,


Sounds like you have a pretty solid plan.
