Everything You Need To Know About Planting In Peat Pots

In this blog post, I will answer all your questions about how peat pots work, how you should use them, how they are made, how long they last before decomposing. And anything you need to know about these nifty little things!

In fact, I found that planting in peat pots is a great way to start seedlings that I eventually transplant into the ground or indoor garden. You can use them for various plants, from flowers to vegetables and everything in between!

They are also a biodegradable alternative to plastic pots that comes in many shapes and sizes. And yeah, you can also make them at home using materials you probably already have lying around the house.

So, let’s dive right in.

What are Peat Pots?

Peat pots are biodegradable containers made from peat moss, a type of organic material found in wetlands. The peat moss has been dried and compressed into blocks, then molded into various shapes such as cylinders, cubes, or bowls.

Peat pots can be used to start seedlings indoors before they’re transplanted outdoors. They are also great for starting herb and vegetable gardens, as they can be placed directly in the ground when ready to plant.

Peat pots allow roots to breathe better than plastic containers, allowing for healthier root growth without becoming waterlogged and increasing the risk of fungal diseases. They also provide an ideal environment for seedlings since peat moss is able to retain moisture much longer than soil alone.

How are Peat Pots made?

Peat moss comes from decomposed plants initially found in bogs and marshes, formed over centuries by a natural process of extensive decomposition underwater or saturated soil conditions. It’s rich in nutrients like nitrogen, potassium, calcium, magnesium, and phosphorous, making it perfect for growing healthy, nutrient-rich plants! 

Commercially, manufacturers of these pots will take large quantities of peat material and thoroughly saturate it in water, causing it to turn into a thick muddy mixture. They will add some wood pulp to this mixture for rigidity and blend it thoroughly into a peat slurry.

Once the slurry is prepared, it will be pressed into forms. Pressing it compacts the moss and wood pulp into its intended shape and squeezes out most of the excess liquid. Tightly compacted together, it will be dried thoroughly, creating a biodegradable pot.

Due to the addition of wood pulp, these pots will hold their shape long enough that starting seeds in peat pots shouldn’t be a problem. However, the pot will eventually lose form, so it’s essential to plant your seedlings quickly once they’re ready.

A planting pot can also be made at home using materials you probably already have lying around the house. Look further for details.

What plants can you be planting in peat pots?

If you want to grow plants in a peat pot, choosing plants that don’t need deep roots or adapt well to shallow root growth is best.

In this case, your options are many:

  • Herbs are usually great for starting out in peat pots and come with the added benefit of being easy to transplant.
  • The same goes for starting cannabis seeds in peat pallets.
  • Vegetables like tomatoes should be transplanted as soon as possible due to their long taproot, which will pull up any nutrient-filled soil on its way down. They’ll still last without proper drainage for some time if they have one leaf poking through the top while staying moist from rain overhead.
  • If you want flowers to start them now because even though seeds can take weeks before sprouting into shoots, once they do, they’re ready for transplanting
  • You can also use peat pots to start seedlings.

Keep these tips in mind when planting your next plants so that you can get off to a good start!

Can you grow plants in just peat moss?

No, you can’t grow plants in just pear most as it is not a complete potting mix and needs at least one more ingredient, such as sand, perlite, or compost, before using it for plants.

What are the different types of peat pots?

There are a few different types of peat containers, pots, strips, and peat pellets. They all have their own use cases, which I will explain right now.

Some people prefer looser material that allows the plant root system to penetrate more deeply. In contrast, others like it tightly packed, not letting any moisture escape.

Peat pots

biodegradable peat pots

Peat pot is the most common type – these look like small plastic containers with drainage holes in the bottom, which you fill with potting mix and plant your plants into. 

Some come with an insert, so removing those once roots start growing through them is easy! You can also buy biodegradable pots. The size ranges from small miniatures for seedlings up to large containers for trees and shrubs.

Peat strips

Peat strips

Peat strips are long strips of peat moss that are typically used for seedlings. They are the cheapest and most eco-friendly option for planting.

These pressed peat strips form little chambers that serve as rows in a seedling tray. However, you can use a razor blade or scissors to cut the chamber into sections. These cut sections may even separate from one another by hand. 

You then plant the whole section with a pot attached, which causes less transplant stress because the layer of peat within will eventually break down over time. However, they are designed to be lightweight and will only hold up long enough for the plants to get started. You’ll need to transplant these plants quickly before the peat layer starts breaking down.

Peat Pallets

peat pellets

Peat pellets comprise many individual pieces, making them more expensive than strips but cheaper than plastic pots. When these pellets arrive, they’re small compressed discs.

These pellets do not use wood pulp as the standard pots or strips. The biomass is covered with a fine mesh material, giving the pellet some shape. 

Some kits come with peat pellets and a plastic tray with round indentations for the discs. The instructions for Jiffy peat pellets say to pour warm water over them until they have fully expanded before planting plants.

Once warm water hits the compacted pellets, the pellet starts to swell up, forming a cylinder of peat that is barely held in place by the surrounding bio-mesh. There’s usually a tiny indentation in the planting side, making it easy to drop a couple of seeds inside. It’s almost like using miniature fabric pots!

How to use peat pots?

To use them, moisten the peat pots, fill them with potting soil, and place them in a tray. Place seeds in each pot, push them into the soil, and add water. If your peat pot has a humidity dome, now would be the time to place it on top. Place the peat pot in a warm place in your home. You can also set the tray on top of the seed starting heat mat if you need extra warmth. Keep the pots constantly moist. Once you have a true set of leaves appearing, remove the cover and put the tray in a sunny place or move to a larger container.

When using peat pellets, you should lay them in a flat layer on top of your potting mix and then add more soil to level with the peat pot. If you’re using strips, cut the piece to size for how deep a container you want and use scissors to make slits around it where you’ll hold onto it when placing it into the ground.

Whether you’re using seed pots, strips, or pellets, you must set them into a tray. The peat moss provides some warmth which helps the plants germinate quickly. Just make sure to avoid placing them in direct sunlight.

Here is a great video that shows you a few quick tips for using peat pellets to start seedlings:

How long can seedlings stay in peat pots?

You can keep most vegetables and flower seedlings inside the starting seeds pot or container for at least two weeks. Still, after getting their first set of true leaves, you’ll need to transplant them into a larger container or raised bed.

When transplanting plants from pots, loosen the pot base to make roots easier to break through. 

Taking a razor and making shallow cuts around the bottom of a pot or through the pellet base is essential before transplanting. This makes it easier for growing roots to penetrate through and extend into the soil where it has been transplanted.

Take care not to damage roots while doing this. If they are damaged during transplanting, plants could suffer severe shock after planting! 

Place newly transplanted plant deeper than its original depth now that there’s less root mass exposed – about as close as how deep you initially planted the plant.

Continue watering and fertilizing as usual, just like how you would wet your plants in a traditional pot garden or container gardening.

Peat pots are handy for planting tower gardens that have oddly shaped spaces. When wet, the peat pot becomes flexible and easy to set into place.

Do peat pots dissolve?

Yes, peat pots are biodegradable plant pots and will dissolve over time and decompose into the soil. So make sure not to water excessively- which speeds up the process!

There’s no set time frame for when peat breaks down into compost. Many factors are involved:

  • How big was each pot?
  • What type of soils were used?
  • How often did you water them (not too much)?
  • How closely together were they planted etc.?

However, they do not last as long as disposable plastic containers do. 

This means that eventually, roots will break through the bottom of a peat pot and loosen it from its place on top of the root ball. When this happens, you’ll need to make another set of fresh peat pots or use something else, like biodegradable planting pellets instead.

How do you make a peat pot at home?

If you want to make your own peat pots, you can use several materials. You may want to consider using the following:

  • Cutting up sections from sphagnum moss. Notice there is a difference between sphagnum moss and peat moss.
  • old coffee filters, toilet paper, recycled paper, or newspaper strips
  • Cheesecloth and toilet tissue rolls
  • Newspapers

When using peat moss to make your own pot, it is best to mix the moss with some compost, soil, and sand. This mixture should be moistened before being placed in a pot shape.

After you have made your peat pots, they need to be set out in the sun to dry. Once dried, these will start decomposing on their own or if left outside.

If you want to make an entire pot from all other materials, either newspaper strips, toilet paper, or coffee filters. Ensure to soak them in water and place them in a pot shape.

After making peat pots, there’s only one thing to do–get gardening! The best way to ensure success while using this type of container is to have drainage holes at its bottom and be sure not to water too heavily when seeds are first planted.

Peat pots are also an excellent option for starting seedlings because they provide a warm and humid environment perfect for root growth, making transplanting much easier later.


If you’re looking for an eco-friendly alternative to plastic pots, peat pots are the perfect solution. They work great with different plants – from flowers and vegetables to those needing a little extra pot time before being transplanted into the ground or garden.
