Feeding Chemical Fertilizers
When choosing a fertilizer, be sure that you know the type you need.
First you should use feed that is meant for vegetables such as tomatoes.
Now you need the one for your specific goal. For root development, a higher ratio of Phosphorus(P)
is neccesary. Use a root starter/transplanter feed like 10-52-10. Notice the P ratio. Other numbers
are fine as long as the ratios are similar. They also contain all of the necessary micronutrients needed
for this stage.
