Barbados-born Archer took six wickets – including 5-102 in the second innings – in the opening Test of the series and, after missing the last two, could return from an elbow injury for the fourth and final Test in Johannesburg.
“It’s been a very frustrating tour for him for a number of reasons with his injury,” added Root.
“Also, someone at the start of his career coming to South Africa and taking a five-for and having to miss out on the next couple of games, is never an easy thing to take as a young player.
“There have been a number of learnings for him so far on this tour.
“We are very keen on making sure that we try to get the best out of Jofra – keep creating an environment where he can learn, develop and not stand still as a player and keep growing in Test cricket.”
Archer could play in the fourth Test along with fellow pace bowler Mark Wood as Root considers his starting line-up.
“It would be nice to see how they go together,” said Root.
“I think they would be a relentless barrage of pace which is exciting, especially on a surface such as you typically get here at the Wanderers.”
