    I’m Mindy, and I write for Veggie Knowledge when I’m not out there making a mess in my garden. I’ve got a background in environmental science, which sounds fancy, but mostly it means I geek out over dirt and compost way more than the average person. Been growing veggies for over 10 years now, ever since I planted my first tomato and watched it die ‘cause I forgot to water it for a month. Total rookie move. I’m still a bit of a chaotic gardener, but I love sharing what I’ve learned, like how to keep your plants alive and maybe even grow some food you can actually eat. My garden’s a jungle half the time, but I wouldn’t have it any other way.
