Om Nationale Boomfeestdag te vieren, besluiten de vrienden een geweldig tuinproject uit te voeren voor Charlie Brown. Helaas komt Charlie Brown erachter dat ze het op zijn honkbalveld hebben gedaan en er een weelderige tuin van hebben gemaakt. Zonder alternatief wordt hij gedwongen om op dat veld tegen Peppermint Patty's team te spelen. De bizarre omgeving lijkt echter in zijn voordeel te werken.
Nee, helaas is It's Arbor Day, Charlie Brown nog niet beschikbaar op Netflix in Nederland.
