I own 6 Guinea Pigs and they like to eat so I decided to grow vegetables for them. I have 2 grand daughters and thought heck Halloween is coming I'm going to grow some pumpkins. Well, all of it is doing good or so I thought. I have major mold on my pumpkins . I just started working on getting it under control with the water, dish soap and baking soda.. I hope it works, I was hoping to get 20 pumpkins for their halloween party. My question is how much do I water ? I live in Southern California (zone 6). I am not clear on how much to water so I water a lot and I think that is why I have so much mold.
