I am close to having to up-pot my tomato plants from thier individual cells I started them in (used Jiffy Seed Starting mix), to bigger 3" pots.
I purchased a bag of Miracle Grow Garden Soil yesterday but after bringing it home, I noticed that it said to not use this product to container garden. I am using it to grow my seedlings in containers for now, but eventually, these plants will be either up-potted to 5" pots or they will be moved to my outdoor garden.
Should I buy a different bag? If so, can I have some recommendations?
anndev, If I have to pot up I alway use Miracle Grow Moisture Control, it also goes into all my hanging baskets and containers. I lost count of how many bags of this stuff I go through a season, at the end of my growing season I use the spent soil in my flower beds or vegatable garden or any place I want to improve the texture of my soil, I have clay.
I would definitely go get a bag of something that's meant for containers--garden soil doesn't drain well enough in containers so it's important to use a container mix. I use Miracle Gro container mix without the moisture control. I don't know if it's that much better than other brands, but it's readily available and not too expensive and it's always worked fine for me.
I use the same material that I use for starting seeds. Buy a compressed bale of peat moss, screen it with a 1/4 inch hardware cloth and add perlite. I use this for starting and potting up about 1500 plants each year. The packaged mixes are way too expensive if you have more than a couple of hundred of seedlings you are growing.
