Make sure you check the bus schedule in advance. Meitetsu’s bus website is a bit convoluted but you can search for the bus by plugging in starting from 高蔵寺駅北口 and going to 植物園. It’s only 7km to the trailhead so if you have a couple of people then a taxi shouldn’t be too costly.
I recommend not only downloading the digital map from YAMAP, but also printing this simple paper map that you can use to cross reference against the numbered signposts on the approach to Miroku.
