This is the year to grow your own vegetables! And we have the perfect source of inspiration for you. Ashlie Thomas, AKA @TheMochaGardener is sharing her gardening adventures and wisdom with us.
She and her husband Tyler began growing veggies at home in North Carolina in 2019, in hand-built, octagonal raised beds that they named “Octogarden.” Since then, they’ve added more beds and crops, a stunning She Shed designed by Tyler and a greenhouse. Ashlie’s gardens have grown to over 2,000 square feet!
Ashlie has learned a lot about gardening in the last few years. She talked about the mistakes that vegetable gardeners often make when first starting, and offered her ideas to fix them. While you’re at it, check out these other common mistakes every new gardener makes, too.
Mistake #1: Not Knowing Your Hardiness Zone
A basic mistake that Ashlie says beginning gardeners make is not checking what growing zone they live in. Check out this map created by the USDA to find the zone number for where you live. Then check vegetable plants or seeds before you buy, to be sure they can thrive in your growing zone.
Mistake #2: Forgetting to Test Your Soil
All soil is not the same! Your soil could be acidic or alkaline, sandy or, as Ashlie found in her own backyard, heavy clay. Purchase a soil test kit or talk with your local extension service to learn how well vegetables will grow in your soil. You can learn ways to improve your soil with organic material, or for the most control, plant in raised beds (like those beautiful octagonal beds Ashlie’s husband built) instead of planting in the ground.
Mistake #3: Beginning Without a Plan
This is another way that Ashlie says beginning vegetable gardeners struggle: They don’t have a gardening plan based on the best growing times for their plants. And it happened to her, too! She mistakenly planted a crop of bok choy too late in the season, only to have it bolt in the summer heat. Read the growing guidelines for your vegetables. Some, like bok choy and greens, grow best when planted in spring, while others like peppers and tomatoes prefer the summer heat.
Mistake #4: Not Understanding Your Space
What’s going on in your yard? Where is the shade? Where are the full-sun areas that your veggies will love? Do you know where your septic system is? (Don’t plant there!) Do your homework before choosing and planting your vegetables. And you don’t need acres to have a garden. Ashlie recommends taking advantage of small spaces alongside your house and garage, and to use raised beds and containers.
To maximize your space, think outside the box. Learn how to make a vertical pallet garden.
Mistake #5: Thinking That Vegetables Are Hard to Grow
While there are a few things you must have (sunlight, good soil, the right climate), there’s no reason to feel intimidated about growing your first vegetables. Begin like Ashlie did: with a few plants, adding more each year as your confidence grows. Using raised beds and containers can make physical access to your garden easier.
Want some easy, forgiving veggies to start with? Ashlie suggests cucumbers, which are prolific growers, peppers, and any variety of kale. “Kale does well in drought or frost. It’s very loyal and resilient,” she says. It’s also satisfying to plant fast-growing vegetables.
Mistake #6: Letting Your Garden Go Unattended
Your plants may be in the ground, but your job isn’t done! Ashlie likes to remind beginning gardeners that their vegetables need monitoring “like a baby.” Consistent watering is important, but she says to also look deep: check undersides of leaves and ripening vegetables for pests and diseases, and check for weeds. You want to catch problems early before they hurt your whole crop.
Here are tips for dealing with the worst garden pests.
Mistake #7: When Something Goes Wrong, Not Asking Why
Ashlie notices that beginning gardeners often blame themselves when their veggies don’t grow the way they should. She says it’s important in those moments to not get frustrated with gardening, but to get curious: learn what went wrong and how to fix it for next season.
Ashlie shared one of her own gardening setbacks when squash vine borers decimated her squash plants. She decided, “Am I going to stop growing squash? No I am not!” Instead, she learned ways to protect her plants from pests with products like diatomaceous earth and neem oil.
Mistake #8: Giving Up!
Ashlie’s gardening success and beautiful crops of veggies haven’t happened by accident. Her gardens thrive thanks to respect for the environment, persistence and resilience. “Gardening forces us to face many challenges,” she says. “Fear that we’re not going to be good enough, fear that it won’t look like what’s on Instagram. We all fail. Take it as a learning experience.” Ashlie’s last piece of advice? “Keep going, keep growing!” We think that’s the best gardening motto we’ve ever heard!
