With the way yours look, I would stick a bamboo stake in the ground a little bit behind them and gently pull the main stem back a little (not too much) and tie it to the stake. In a couple of days pull a bit more and readjust your tie. For most of my plants I open them out like a cross - pull the main stem back, larger arms to the sides and lower branch forward. That requires four stakes but you can use one stake between two plants. I also use long skewers. Some people weight with string and rocks. The key is go slow.
If you are going to do it, do it right away while they still have a little growth time left and they will set new budsites within a few days!
