Garden Recommendation: Peat Pots

Tomato Starts in Peat Pots

Sunsugar Tomatoes Transplanted into Jiffy Peat Pots

On our farm we plant 1,000’s of tomato plants, each one grown from seed. We start the seeds off in a standard 1020 flat, growing them under florescent lights in our heated basement. When they are large enough and the weather has warmed up we can set them out in our unheated greenhouse. When the plants are large enough we transplant them into Jiffy pots to give them more room to grow. The size of the peat pot depends on the size of the transplant as well as how early in the season it is. We use large 4 – 3.5” peat pots for our earliest tomatoes. We downsize for the mid-season and late tomatoes.  When the weather is right we plant them out in the field, pot and all. In doing this the plant will not suffer root shock but gradually stretch its roots as the biodegradable pots decompose. The only drawback I have found to peat pots is their tendency to evaporate moisture quickly while they are growing in the greenhouse. Plants in peat pots will have to be watered more often compared to plants that are in plastic pots. You can purchase peat pots HERE.

Quick Facts About Peat Pots and Biodegradable Pots:


Perfect for plants with sensitive roots such as Nasturtiums.

No plastic pots to deal with after the season is over.

No problem with root bound since the roots grow right through the peat pots.

Quick decomposition of these biodegradable pots helps the environment.


Frequent watering.

The peat pots may break down before they are set in the ground for plants that were started inside extremely early.

Environmentalists believe peat is being harvested faster than demand. (Alternative is coir pots, although I have not personally worked with them.)

    Thank you for this post. I start my seedlings directly in a bed in our unheated greenhouse, and have never transplanted them prior to bedding outside, but I think I will try your method with some of them this year and see which works the best in our garden. :)

    Good idea, experiment with some of your plants this year and see if the peat pots help you out. I find they especially work well for the seedlings we started really early.
