Dutch elm trees will be planted to replace their diseased predecessors.
Last year wardens worked with residents to plant more than 30 trees in Saltwood Road, The Shepway and Chyngton Avenue in Seaford.
Following positive comments from locals, wardens will plant more in the coming months with the help of residents and children from Chyngton Primary School.
Seaford tree warden chairman Keith Blackburn said: “Sussex still retains one of the largest populations of elms surviving in the UK because the South Downs provided a natural barrier against the disease.
“Nevertheless, each year elms are lost and many Seaford residents will have been dismayed to see the large number of elm trees succumbing to Dutch elm disease this year.”
Wild flower planting under the new trees is also planned.
Wardens will also help representatives from Mercread Youth Centre, Seaford Football Club and Seaford Rotary Club to plant about 30 in Crouch Gardens on December 1.
