well In my experiences...
if u gro out doors u really no need the ferts....Tho they will help...
unless u r in ur garden at home Once a month ferting outside is plenty...
keep them topped as they will grow tall and noticable...
never plant all in the same area...have 3 or four spots....lottsa human hair(barber shop garbage cans )..
start ur seeds inside 3 weeks prior to the day u wish to plant outdoors..
plant 1 week after last frost of spring...
here its may 21 central canada..
always IMhop...
keeps..
