Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.

I planted 36 Tamato berries. 18 had no mulch, 18 had Rich Mulch. I watered them as soon as they had dried out and weeded about every 2-3 hours when awake (except for one day I got sucked into calculating IV passing probabilities and forgot about them for 8 hours).
