Hey,
It's my frist time growing the tidal wave variety, and so far they're really fast growers(compared to other petunias). I'd like to know if they should be pinched like regular petunias, or should I just let them grow? They seem to branch out on their own (picture). I'm also aware that they are heavy feeders.. so can I start fertilizing right now or wait till they get bigger? I plan on using them on window boxes and hanging baskets.

Thanks,
Mauricio
