Nettle Feed

What are nettle and comfrey feed used for

 

My understanding is that nettle feed is for leafy growth and comfrey is fed when plants are in flower or fruiting. I only use comfrey feed and my first batch of the year should be ready in the next week or 2.

Thank you for your help

 

I agree with rusty, I remember my grandmother's neighbour using comfrey on her chrysanthemums and on veg when fruiting too. Seemed to make an incredible difference.
