How do I plan a tight hosta bed?
I am new to hostas.
I prefer the look of a closely planted hosta bed, one where all the hostas touch each other and there is no visible mulch or soil between them.
But I don't know how to determine the correct spacing between hostas so that they fill in the bed. Do I need to account for a period of time where they reach their full potential? If so, how long might that be?
If I have a tight hosta bed, does it follow that I will need to divide the hostas more frequently once they are established?
