Key ingredients for container soil/mix for tomatoes?
This is my first year of tomato gardening. All my plants are in large 25-30 inch containers (At least 20 gallons)
As a newbie, I used ready made mixes - mostly Miracle Gro and some pots with an organic soil mix that I bought at a local nursery. The results are okay but nowhere near the production I've seen people talk about here.
I'm ready to plant some tomatoes for Fall, but this time I'd like to ensure that my potting mix has all necessary ingredients.
I have big bags of Sphagnum Peat Moss, Perlite, Mushroom Compost and sand. What other ingredients should I consider? Someone told me that I may need to use some dolomitic lime to balance off the acidity of the peat.
Any suggestions? Thanks
