I do fertilize with manure and 10-10-10 in the hole when planting to the garden and then give each plant a watering of 1/2 quart or more or full strength miracle grow depending on how wet the soil is. The plants are 18 to 24 high at that time.Potting soil has enough nutrients to sustain plants for six months.ne conclusion I've come to is that most of us *over*-fertilize our tomato plants. But there are so many different ideas about what to use, frequency, dilution ratio, etc. Some say a very dilute solution of kelp or seaweed, or miracle grow.
