When you’re growing your tomatoes in containers, what size pot do you use, and what fertilizer do you recommend?
For tomatoes, the larger the pot the better! This is one time bigger is really better. I like 20-25 gallon pots, but anything 18 inches or larger will work. I add Osmocote for a slow release fertilizer and a source of calcium to the potting soil. And yes, add Soil Moist (now also using coconut coir) to help reduce watering, which the larger pot will help as well. For the fertilizer, I use Espoma’s Tomato Tone (has calcium added). And plant your tomato plants deep, for better rooting.
