The county have erected a giant marquee over the square at Chester Road to enable them to play on outdoor wickets rather than practice indoors.
New Road has been subject to four floods in the past three months and the practice nets and square have had to be re-seeded.
Worcestershire chief executive David Leatherdale said: "The square and nets were re-seeded 10 days ago and the plan, weather permitting, is for the players to return in early April.
"The marquee has been put up at Kidderminster to enable the players to bat and bowl on outdoor wickets rather than in indoors."
Leatherdale remains confident the square will be ready for the start of the season, adding: "It is already looking 10 times better and there are no home games until May."
