I planted 70 Starfruit with Deluxe Speed-GroAny Robin buildings you want? Seeds? There's still plenty of time in the season to plant more - you can even still plant pumpkins today (or even later with speed-gro). Tool upgrades? Animals? Materials for crafting? Or just save up for some of the really big purchases.
In that case you can get a lot of raw materials for sprinklers and get a army of pumpkinsalso i meant summer
