Just plant the entire peat moss pot when you transplant the seedling into the garden!
The only seed-starting method many gardeners will use, Jiffy Pots revolutionized gardening and continue to be one of the most popular ways of growing from seed for transplant into the garden. The principle is simple: Jiffy Pots are constructed entirely of lightweight, sturdy Canadian sphagnum ("peat moss"), so as the roots develop, they eventually grow right through the Jiffy Pot wall and into the garden soil! It's been working like a charm for decades!
Jiffy Pots are great for annuals, perennials, and vegetables, and are especially effective for hard-to-transplant species. Because you plant the entire pot without disturbing the root system, many plants which normally suffer transplant shock make the transition without turning a leaf!
The 2¼-inch-high and -wide square pots are ideal for placement in trays. For larger square Jiffy Pots, consider the 3-inch size. Each size sold in sets of 100. For round Jiffys, click here.
