Buying Guide
FAQs
What should I consider when choosing between peat‑based and peat‑free seed starting mixes?
Peat‑based mixes like Espoma and Jiffy offer excellent water retention but raise sustainability concerns because peat harvesting impacts wetlands. Peat‑free options such as Back to the Roots, Burpee Coconut Coir, and Seedling Soil use coconut coir, biochar, or other renewable ingredients, providing similar moisture balance with a greener footprint. Look at the moisture‑holding capacity, pH stability, and any certifications that matter to you.
How important is mycorrhizae in a seed starter, and which products include it?
Mycorrhizae form a symbiotic relationship with roots, improving nutrient and water uptake, which can lead to stronger seedlings. Back to the Roots, Espoma, Promix Premier, Burpee Coconut Coir, Seedling Soil, and Premier Horticulture all list mycorrhizal fungi in their ingredients. Choosing a mix with mycorrhizae can give your plants a head start, especially in nutrient‑poor soils.
Which mix offers the best pH control for a wide range of seeds?
Back to the Roots includes dolomitic limestone to neutralize acidity, while Jiffy adds lime for pH balance. Promix Premier supplies pH test strips, making it easy to monitor and adjust conditions. If precise pH management is a priority, those three mixes provide the most built‑in tools.
How do the moisture‑retention properties compare across the mixes?
Coconut coir in Burpee’s mix holds water well yet drains efficiently, reducing the risk of soggy seedlings. Peat moss in Espoma and Jiffy can retain up to 20 times its weight in water, which is great for germination but may require careful watering. Peat‑free blends like Seedling Soil use biochar and worm castings to balance moisture and aeration, offering a middle ground.
What are the size and value differences for home gardeners?
Back to the Roots and Seedling Soil come in 6‑quart and 4‑lb bags respectively, ideal for small indoor projects. Larger options like Burpee (16 qt) and Promix Premier (16 qt) provide more volume for outdoor beds or multiple trays, often at a lower per‑quart cost. Compare the price per quart and any included extras, such as pH strips or gift packaging, to gauge overall value.
Is any of these mixes especially suited for gifting?
Back to the Roots markets its 6‑quart bag in attractive holiday packaging and promotes a “Grow One Give One” campaign, making it a ready‑to‑gift choice. Espoma’s classic branding and the premium look of Promix Premier also work well as presents for gardening enthusiasts. Consider the presentation and any added accessories when selecting a gift.
Do any of the mixes include additional nutrients or fertilizers?
Premier Horticulture’s Organic Pro mix (both the 16‑qt and 1016041RGCE versions) contains an organic fertilizer that feeds plants for up to three months, plus MycoActive for vigorous growth. Back to the Roots emphasizes its nutrient‑rich, peat‑free formula but does not list a separate fertilizer. If you prefer a mix that feeds as seedlings develop, the Premier Horticulture options are the most comprehensive.
Which product is the most environmentally friendly?
Burpee’s Coconut Coir and Seedling Soil are both peat‑free and use renewable or recycled materials, minimizing impact on peatlands. Back to the Roots also touts a peat‑free composition and USA‑made production, adding to its eco‑credentials. Choose a peat‑free mix with recyclable packaging for the lowest environmental footprint.
