How To Succeed Growing Plants In Peat Pots

In the last few years I ran my greenhouses and nursery business, I switched the entire production to peat pots. I became disenchanted with selling hundreds of thousands of plastic pots and knowing they were simply being dumped into landfills. I did learn a ton about growing and gardening in this kind of organic pot in a big hurry and here are a few things you need to know.

  • I prefer square to round because you get slightly more soil for growing your plant in a square pot. And they fit flats better without falling over.
  • They are “messy” in that they don’t hold water but leak it everywhere so do plan on having a tray (without holes) underneath them at all times while you’re using them.
  • Only get them wet when you decide to use them – they’ll be soggy mess otherwise if allowed to sit (remember they’re peat)
  • Overwatering will cause algae to grow on the side of the pot. This isn’t a major problem but it is hard on the clean hands when you start transplanting. I never worried about it with my own plants. Length of time to grow.

Nurseries use plastic for the most part because it doesn’t break and can be shipped easier. The only time fibre pots are used now is for spring-dug and shipped plants. They’re not usually grown in these pots. Clay is now only used by some specialty nurseries (mostly the older ones)

Are There Differences In Growth?

There was no difference between plastic pots and peat when it came to actual growing time of the plants or plant performance. Both grew great plants for me.

However, the pots had a limited growing time before they softened right up and started to deteriorate.

If we transplanted perennials into them in February, by May the pot would be extremely soft and starting to break down. It often came apart in customers hands. This is good for the garden but not good for sales.
Shorter lengths crops such as vegetables and some annuals were fine. The pots would be softening up (and getting some algae on them) but were still salable.
On the home scale vegetable or annual garden, they are fine.

Planting Instructions

The one thing we did find with garden performance was that if you left a lip of the pot over the soil line, it would dry out.
The problem was that sometimes it would dry the entire pot out in dry soils. This meant that any tender roots that were trying to penetrate into surrounding soils were dried out and killed. As you might imagine, this isn’t a great way to grow a plant.

To prevent this, you need to remove the lip of the pot below the soil line in the pot. A haf-inch (1 cm) is fine for this.

And you need to keep the surrounding soil quite damp until the plant is firmly established and growing strongly.
But having said all that, I think peat pots are the best environmental option  (Amazon) we have at the moment instead of plastic.

How To Make A Raised Garden Easily and Cheaply

One of the big projects in our garden adventure is making an entire garden – a raised bed garden as it were.
You see, we have almost no soil and if you don’t count the two-inches of clay over 8-inches of limestone shale rock as soil, we have none at all. So we need raised beds to garden. We’ve had them in various forms over the past six years on this garden and it’s time to get serious about them.

Raised Garden Materials

I decided to use 2×4’s. Plain old spruce standard stud wood.
I then treated them with vegetable oil.  My thinking here is that using pressure treated wood is “problematic” for organic gardens, old railroad ties leach creosote, and even if this wood only lasts a few extra years, I’ll get a solid ten years out of each cheap bed – and they can be replaced for less than any other alternative.
2.5 inch deck screws – lots.
I use a power drill to pre-drill the holes and then screw the bits together, this amount of hand tool work would take me forever and would leave me with popeye-sized forearms.

How Deep Is It?

I’m using 4 boards stacked one on top of the other so we wind up with fourteen and one-quarter inches tall but figure fourteen if you’re a chainsaw carpenter like I am.

Corner Details

Here’s the raised bed corner detail. It’s standard construction system stuff.
I cut four lengths of fourteen-inch 2×4 for the corners. And all wood is screwed to these corner pieces.Here’s the Final Project

The picture below will give you as much detail as you need – no fancy raised bed garden plans necessary. 🙂
The corners are constructed as above. Four boards high.
The length is standard, uncut eight-foot lengths.
The standard width is thirty-six inches but this is 34-inches (see below).
Important – if you make it wider, you’ll have difficulty reaching into the middle from either side.
Yes, it seems like a waste of wood or you can do what I did and shorten it down to thirty-four inches wide and that gives me two ends and two upright corner bits from each standard length – no wastage and easier to reach into the middle as well.

The green frame is a season-extending cold frame system (used to warm up soil for very early crops or protect from late frosts) And the solar light is to mark the edges at night so visitors don’t kill themselves walking into it. 🙂

Two Construction Details To Consider.

squaring corners
Get your corners square
The garden beds should really be square and I’ve used a carpenter’s square to get mine right, I’d suggest you use a similar tool.

levelling raised bed
Getting a bed to be level is a useful step and I recommend it highly.

Raised Bed Garden Soil

I use standard garden soil in them but I add copious amounts of peat moss and compost to each bed every year. I dig this material in and after a few years, I’ll have a great soil that grows darn near anything I need to grow.
I have experimented with soilless mix in raised beds and it does a reasonable job as well but you do have to add a lot of compost and peat every year (more than regular soil) because of the shrinkage and degradation of the soilless mix.

Bottom Line

If you don’t have much garden soil (like our garden) or if you have a physical reason to avoid bending over, a raised garden bed may be your solution.
This simple raised garden system is inexpensive, long lasting and works nicely.
