Best seed starting mix!
This seed starting mix was light and airy. It allowed the seeds I planted to germinate well. It also held water well without being soggy. This soil mix is of high quality and appears to look really good. Some other mixes I’ve purchased tended to have pieces of mulch wood in them. This mix doesn’t have that filler and is top notch!

Excellent for starting seeds and African Violet propagation
This is the product I have used for years for seeds and propagation of African Violets. Always satisfied. Good drainage . Perfect function for root development. I experienced occasional development of moss, which means I overwatered. I scrape it off the moss and allow some drying with resolution. Rich brown color.

Rich Organic Soil!
As an avid gardener I have learned that the most ideal and possibly the best garden soil has to have the right mixture of chemical components, physical components and biological matter to achieve optimum results. 1. Chemically soil must contain adequate amounts of essential nutrient contents, (such as nitrogen, phosphorus, potassium), be of suitable acid-alkaline reaction (pH levels), and free of substances toxic to plant growth, (such as herbicides). 2. Physically soil should allow water to drain through and air to gain ready admittance, but not so loose that it does not retain enough moisture and nutrients for the plants’ needs, (in other words moist well drained soil). 3. Biologically soil should contain an abundance of favorable organic matter (humus, which is what remains after extensive decomposition of organic matter), and other helpful soil organisms (such as earthworms) and a minimum of harmful ones, (such as nematodes). When the above three conditions are met, the gardener now has rich organic soil to successfully grow and harvest a variety of crops. Espoma Organic Seed Starter Premium Potting Mix has all the above components; it is dark, rich with organic matter, moist, soft and light. I was able to successfully grow and reap a bountiful harvest of tomatoes, hot peppers (serrano and habanero), lettuce, broccoli, cucumbers, carrots and a wide variety of herbs and flowering plants, using this seed starter mix and followed up with Espoma Organic Potting Mix. This is the best organic potting mix I've used and it gave optimum results. A+

Stunted seedlings
I used this soil for the last three years and had great success with my seedlings. Something was different about it this year. I don’t know if they changed the ingredients but every single one of my seedlings stunted and were completely destroyed. I planted hundreds of seedlings, and none of them developed their first set of true leaves. Unfortunately, these were all varieties that cannot be bought at garden centers. The seedlings would dry out multiple times a day and not retain the water well at all. I’m so disappointed and will not be purchasing this product again.

Well packed for shipping. Arrived quicker than expected. Soil is a nice dark colour, light in texture, and smells clean and earthy. My seeds began sprouting 3 days after planting, and are growing well. It's everything I had hoped for so will order again.
