create or find a bed, get lots of wood, 1 or more torches and grappling hook of any kind.

when you find plantera bulb build a wooden room with a soace between bed, workbench and door.

summon plantera and stick around the house, with a set spawn point and plantera being unable to flee when you die, it will stick around.

I fought plantera using this method with wings, star veil, spectre boots, melee emblem, ice turtle shell, chlorophyte claymore, 5 light discs and full set of turtle armor.

for the first phase i used light discs and sticking around the house, next phase i grappled to a few blocks with ivy whip and plantera took damage from turtle armor and chlorophyte greatsword and i took less due to ice turtle shell and turtle armor.

accessories do not matter.
