When the dead seedlings were discovered, fundraiser organiser and local gardening-in-schools initiative PiPS sent out a call for help.
The schools were overwhelmed at the community response, with Good Neighbour, Mount College horticulture students, Teacher In The Paddock and a Welcome Bay gardener all helping out by donating new seedlings or other goods.
The fresh plants have now been carefully potted up by the students and the sale will go ahead as planned.
Rodgers said the students at Arataki Primary School, a decile one school, were especially overjoyed at the good news.
"To show that the wider community was rallying around them it just meant so much for them.
"The community spirit in all of the schools is incredible and parents do want to help their local school."
Aside from the seedlings, a range of other goods will be on offer including a sausage sizzle, bake sale, coffee cart and a bike fix-up mechanic station.
Live music will be provided by Mount Intermediate School's band, Revolution Radio, who won the 2018 Rockshop Bandquest regional competition.
