The annual maintenance closures begin on select fields from March 8 and will continue until April 6.

Parks crews will undertake a range of procedures to make the most of the increased rainfall and prepare the sports fields as well as possible for high traffic over winter.

From insecticide spraying, weed spraying and fertilising of all parks areas, through to oversowing the main sports fields, it's going to be a busy few weeks for the team.

"This is a crucial time for us every year but this year our team really has their work cut out for them with the increased rainfall we've had and resulting high growth," council's community spaces, recreation and trades manager Daniel Aldridge said.

"In saying that, we're in a completely different place to where we were this time last year and it's been great to see the state of our parks and sports grounds continue to improve over the 12 months post-drought."

Council's parks team mow sports fields to a regular schedule, weather permitting, but the drought of 2019-20 meant a renovation program was established to assist the local grounds in their rejuvenation.

The program consists of vertical slicing, top soil where required, along with the oversowing and fertilising.

Council also purchased several additional travelling irrigators to continue to improve and maintain the playability of the fields.

Football Mid North Coast general manager Bruce Potter said "we've always been very supportive of council's maintenance closures."

"Every year we start our season on the back of this work being done and there is always a noticeable improvement, it's great," Mr Potter said.

Despite some criticism from the community, council said the majority of sports clubs support the closures and the work council does to maintain fields in the region.

"We're continuing to get regular feedback from local sporting clubs who say the sporting fields are looking the best they have in a long time," Mr Aldridge added.

"While we know that the combination of the rain we've had along with the decrease in activity last year due to COVID has certainly helped with the regeneration of the fields, we're hoping to keep on this trajectory with our maintenance closure this year."
