Supporting them??
Not sure I am 100% clear on that?
They sprawl on the ground..
Another FYI, the first year you plant them,
you want to cut off any shoots they send off to
the side/or out..
You want them to get a good rooting system in..
and maybe even pinch off a couple of the first
flowers.
That root system feeds those strawberries, and if it's
busy making strawberries or sending shoots out *that makes new plants* the roots won't get a good developement going on..
And for at least 3 years you don't want to let them send out shoots..
Maybe after the 4th.. and let those babies attach themselves to soil, and let them grow..
The momma plant won't live forever, a good handful of years,
but decline after a while...
And my strawberries are very hardy, I even over wintered some plants in a 6 pk container that never got planted...
and they did great for me the year I finally got them in.
The only covering you may need to do is to keep the birds out..
But remember snails, slugs, mice, woodchucks, rabbits, as well as birds eat them babies.. so, keep a watchful eye on them...
