So far, more than 200 organisations have applied for funding compared to just 105 in the first round. From those, 36 schemes were awarded a total of £295,000 to fund tree-planting schemes in their areas.
Organisers of the scheme, which is funding projects to plant one-million trees in England's towns and cities by 2014, said they expected a rush of applications ahead of the 5 September deadline.
Big Tree Plant programmes officer Vinny Ganley said the "slightly disappointing" first round response had been caused by issues such as timing and confusion over the application process.
"We have reviewed the application form and guidance notes and it is much easier to fill out. We are now seeing the application levels we had hoped for."
Applications to rejuvenate derelict orchards in urban areas and villages are among the most popular applications in the latest round, said Ganley. The winners will be announced in October.
