I ended up ordering it. Will report if it works on hosta growth. So far we have second leaf stage on some.

Although I rarely grow much of anything other than a few annuals from seed, I use Foliage Pro on ALL my containers, indoors and out.

This is a pretty concentrated product so be sure to dilute appropriately.

Appreciate the response! I achieved number of house plants that are bordering on too many. They go outside in the summer to fend for themselves. Having started my hosta seedlings early I need to simplify my watering/ growing needs across the border.
