10 Biggest Vegetable Gardening Mistakes

Gardening for the last 12 years has taught me several lessons, many of which I learned the hard way.  In this post I share my picks for the 10 biggest vegetable gardening mistakes. I’ll be the first to admit I’ve made most of the mistakes on this list.  

Learn from my vegetable gardening mistakes and avoid making your own. What lessons have you learned in the garden? Share in the comments below and let’s learn together.

I partnered with Extra Space Storage for this article about the 10 biggest vegetable gardening mistakes made by new gardeners. Running out of room inside the house? Store what you’re not using at Extra Space Storage, and then make the most of the room you have outside by starting a garden.

1. Starting too big

Many people feel like they need to fill their entire available space with garden beds before starting a garden. The process seems overwhelming and many fail to begin. This is one of the most common vegetable garden mistakes I see when helping others to start a garden. 

It’s been said, “there is only one way to eat an elephant: a bite at a time.” The same principle applies to gardening. How do you start a garden? One bed at a time. It’s important to have an overall plan for your garden area, but it’s more important to start small and then add growing areas or garden beds as you gain experience.

2. Choosing a bad location for your garden

No amount of gardening skill can overcome a lack of sunlight and water in the garden. Vegetables grown in the shade are often less productive and also more prone to insect damage and disease. Without easy access to water, watering your garden is inconvenient and you are less likely to do it on a regular schedule. 

Give your garden the best chance to be successful by choosing a garden area that gets at least 6 hours of sunlight (preferably morning sun) and has easy access to water.

3. Thinking soil doesn’t matter

Garden soil is more than just dirt. Dirt lacks microbes and beneficial nutrients, and it’s sandy, rocky, and without substance. On the other hand, soil is full of life. Plants access the water, air, and nutrients needed to survive through the soil. 

It’s important to have your soil tested. A soil test can determine the health of your soil. This is the soil test kit I use. It’s very simple to use. Add organic fertilizer based on the recommendations. This is the recipe I like to use for organic fertilizer

We ask a lot of garden soil. We expect plants to sprout, grow, flower, and produce fruit in a relatively short amount of time. Good soil is the foundation for a healthy and productive garden. These articles may be helpful, “Best Soil for Raised Beds” and “Get Your Soil Ready for Planting”.

4. Planting at the wrong time

When you begin gardening, there are new terms to learn: cool-season crops, warm-season crops, annual, perennial, frost date, days to harvest, direct sowing, and more. Rather than trying to interpret all the information and hope for the best, learn from the wisdom of experienced gardeners. Find a planting calendar meant for your area. Following a trusted planting guide takes the guesswork out of when to plant. If you live in the low desert of Arizona, these are the planting guides I use

5. Planting too many seeds and transplants

Overcrowding plants prohibits airflow, blocks sunlight, and promotes pests and disease. This is the vegetable-gardening mistake I am guilty of most often. I want to plant “all the things!” It is important to understand the mature size and spacing needs of each plant (this information is usually on the seed packet) and allow enough room for mature plants.

6. Improper watering techniques

Incorrect watering causes many common problems in plants. 

  • Watering plants too much or too little.
  • Watering at the wrong time of day.
  • Giving your plants shallow frequent water instead of root-stretching deep drinks.

7. Not mulching your garden

Unmulched crops need more frequent watering and are more prone to weeds and temperature fluctuations. Adding mulch to your garden each season is a simple way to add organic matter to the soil. Mulching increases beneficial microorganisms and earthworms, and also helps prevent soil compaction and erosion.

8. Not spending time in the garden each day

If you are an infrequent visitor to your garden, small problems (such as watering, pests, and disease) may get out of control and become difficult to manage. When you make a habit of spending time in your garden each day, you are more likely to notice issues while they are small and easily contained.

9. Using pesticides in your garden

Pesticides kill the good guys as well as the bad. You need pollinators and beneficial insects to help maintain a natural balance in your garden’s ecosystem. Organic gardening techniques aren’t just good for you and the environment, they are what is best for your plants.

10. Harvesting vegetables too late or not at all

Leaving ripe vegetables unpicked signals to a plant that its job is completed and it does not need to produce any more. Alternatively, frequent harvesting encourages more production. Getting to the point where vegetables are ready to harvest is a big deal! Celebrate by picking and enjoying the fruits of your labor.
