Rated 5 out of 5 by from Fall transplants ready! I bought a bag of Miracle-Gro seed starting mix for the purpose of starting seeds for our fall garden. It worked great and now we have transplants of broccoli, cauliflower, kohlrabi, brussel sprouts, and butternut squash ready to set out. Come on rain!

Rated 1 out of 5 by from Grow plants, own a gnat farm! I try not to turn my nose to products just because of company size and corporate reputation so I've used miracle grow products for quite a few years. I started over 300 plants with the product this year and within weeks I was completely infested with gnats and their harmful larvae. These starts were in isolation with no other plants, soils etc in the area. I'm now trying to save my financial and time investment fighting this problem. I don't recommend this product unless you want to follow it up with even more expense in finding solutions to the problems it presents. It is so odd that you ask gender on a product review.

How long does the seed starter fertilizer last? How long does it feed for?  Weeks? Months?

Asked by: ScTahoe
Miracle-Gro Seed Starting Potting Mix does not have a shelf life or expiration date. However manures, compost, and mulch will decompose over time. For best results, keep the product in a dry location, up off of cement floors. Potting mixes support plant development by providing a light-weight, nutrient-rich environment for root growth. Miracle-Gro potting mixes are formulated to absorb and release water as your container plant needs it. We would recommend that you use the potting soil for a couple months to get the seeds started and then transplant them.
