what is the difference between the two packages?

It's a VERY important difference. The Standard Starter Fertilizer is just fertilizer. However the PLUS version has the all important Endo & Ecto Mycorrhizae enzymes. Those inert enzymes are activated by moisture and immediately begin their fundamental purpose of stimulating vigorous root growth - which is exactly what you want to happen with newly planted vegetation. Additionally, you can sprinkle some of that stuff on your morning cereal for a day-long experience you won't quickly forget - LOL!

What is the difference between this blue label bag and the green bag, both say starter plus ?

Don't know that there's a difference. Look for the dry enzyme listed on the package. But you definitely want the PLUS variety!

Would this item be beneficial for my large potted plants on my deck? Or is this for in-ground vegetation only?

I use bio tone whenever I plant a plant, in a pot or in the ground. It's really good at giving your plants a start with root growth.

When would you use this vs plant tone? i love all the tones when would i choose this one. i divide a lot of plants. plant tone works is this better

Hello, you would use this product at time of planting to help produce large root systems quickly. This will help ensure that new plantings get maximized water and nutrients from the soil
