5 Gardening Mistakes to Avoid so You Can Grow More Food
There are some gardening mistakes that even experienced gardeners make. And these mistakes are usually due to the same misguided advice being repeated again and again online and in gardening magazines. But once you know what they are you, can easily avoid them and grow more food.
Some gardening advice is thrown around so often that no one even questions it anymore. Any time I hear those “tips” being dolled out to gardeners I want to shake my fist in the air!
It’s completely understandable why people make these mistakes—you would think these stores and sites would be trying to help gardeners.
But the result is gardeners making avoidable mistakes that end in frustration.
This post covers 5 gardening mistakes that you might be making, but that are easy to avoid once you know what they are.
- Watering too much.
- Trying to eliminate all pests.
- Buying the wrong vegetable starts.
- Not mulching your vegetables.
- Starting too big—or too small.
The rest of the post will dive into each of these problems. But before you scroll down, make sure to grab your free and easy-to-print cheat-sheet that builds on this post by giving you 11 gardening tips for the beginner gardener that will help you boost your garden and grow more food.
1. A Common Gardening Mistake – Watering too Much
Have you’ve seen this advice before?
“Make sure to give your plants 1 inch of water each week.”
This seems to be the go-to advice on watering that pops up on every plant description and on gardening sites.
But this leads to a common gardening mistake—watering too much.
What you should be doing is observing your garden—both your vegetables and your soil. Here are 2 simple tests you can do.
- Stick your finger in the soil. (Ideally under a layer of mulch, but more on that later.)
- Look for wilting.
If you stick your finger down into the soil and it feels cool and moist right on the surface, then your plants don’t need watering.
When the surface is still nice and moist, then your soil has all the water your plants need.
But you should also look for wilting, which is often a sign of water stress. If you see this, then your plants likely need a top up. But wait until the sun is no longer shining on your plants—they may stop wilting on their own, and this is a good time to give them water.
When you do water, make sure to water your plants deeply. You don’t want to just get the surface of the soil wet. You want the water to go down deep into the soil at least 8 inches (20 cm). The exception is when you’re watering seeds, which are up near the surface.
If your plants are wilting and the soil is still moist, then there are likely 2 causes:
- Something has damaged or eaten the roots.
- Your plant was recently planted and hasn’t had time to grow enough roots to get the water it needs.
In both cases you can water the wilting plants. But if the roots are too damaged, the plant likely won’t recover. If your plant was recently planted, then it just needs some help to get established. Once it stops wilting, (assuming the soil is moist,) then you can stop giving it extra water.
I can go weeks without watering my vegetables even without rain. If the soil is moist and my plants don’t show any signs of water stress, then they don’t need watering.
The benefits will be healthier plants with deeper roots—and better tasting fruits and vegetables.

2. Don’t Try to Eliminate all Pests
One of the biggest gardening mistakes people make is trying to eliminate all pests. The result is people spending a lot of time, energy and money fighting a never-ending battle that they can’t win.
Plus, a big reason people grow their own food is to avoid all the toxic chemicals that are sprayed on produce sold in the big box stores. So why spray your own vegetables and fruit?
It’s not that you shouldn’t deal with the pests—you should. But you should do it in a way that works with nature and brings the pests into balance.
Balance should be your goal—not elimination.
But what happens when you eliminate all the pests? There’s no food for the predators to eat. They either leave, or they never show up at all, and your battle continues.
So to avoid this gardening mistake, you should do what you can to attract the predators of your pests.
A simple option is to plant flowers—lots of flowers! Flowers attract many beneficial insects, including predatory insects.
Planting native plants, adding shrubs and trees near your garden (north side in the northern hemisphere or south side in the southern hemisphere), and adding habitat features like rock piles will also help bring in predators of your garden pests.
But it will take time. So you also need to be okay with your lettuce having a few holes in it. Your vegetables and fruits don’t need to be spotless. Give the predators time to show up before you take action against the pests.
Start now by adding some flowers to your garden. The sooner you do, the sooner you will start attracting the predators that will bring your garden into balance with the pests.
3. Buying the Wrong Vegetable Starts
I could go to a big box store in my area right now and find large tomato starts for sale. In fact, they’ve been available for several weeks.
There are also peppers and other warm-loving vegetables being sold.
So why is this a bad thing?
We’re still getting frosts here, and all those warm-loving vegetables will die if they’re planted today.
This leads to a common gardening mistake—buying vegetable starts too early.
You might think that if the plants are for sale in the stores, then it must be the right time to plant them. If the stores had their customers’ best interest in mind, this would be a safe assumption. But the truth is, they get their plants delivered in big truckloads all at once—that includes cool-weather and warm-weather vegetables.
You can buy these starts, but make sure to look up planting guides for your area before you plant them.
Here are 3 sites that can help you figure out when to plant your vegetables:
There is one more thing you need to watch out for when buying vegetable starts—buying large vegetable starts instead of small ones.
At most stores, you’ll see a mix of sizes of vegetable starts. Some will be in clusters of small cells, but others will be in individual pots—sometimes even large 1 gal or 2 gal pots.
You might think those large pots would be better. But the opposite is true.
The plants in the small cells also tend to be small. But here’s the important thing—they’ll have far more roots compared to their top growth (the green part above ground) than a large plant in a large pot.
Generally, the smaller plants will suffer far less transplant shock and will catch up and surpass the larger plants.
Plus, it’s much quicker and easier to plant small plants!
The big stores like people to buy large plants and buy them early. But doing so will just cause you frustration and waste your money.
4. A Common Gardening Mistake: Not Mulching Your Plants
A far-too-common gardening mistake is not mulching your vegetables.
I remember volunteering at an urban garden. The garden wasn’t mulched at all. And the result was that nearly all my time in the garden, and the time of the other volunteers, was spent pulling weeds and watering.
Week after week of watering and weeding.
Does that sound familiar?
When you don’t mulch you, leave your soil exposed. This creates the perfect conditions for weeds to come in.
Plus, the sun just bakes the soil, which means you have to water a lot more.
A much better option is to add at least 1 inch (2.5 cm) of mulch around your plants until there is no bare soil left.
Just make sure you plant your plants in the soil and not the mulch. Just pull the mulch back when planting, and then return the mulch after you’re done.
If you’re direct-seeding your vegetables, leave the mulch back until the plants grow a bit. Then you can add the mulch back around them.
Large seeded vegetables like beans and peas can push up through a 1-inch (2.5 cm) mulch layer. Though they will likely be slower to come up.
I will add that it’s easier to plant starts in a well mulched garden than direct-seeding. Though you can make either work.
Mulching provides other benefits too. But in the short run, what you’ll notice first is that mulching will result in less weeds and less need to water.
Don’t make the same gardening mistake made by the urban garden where I used to volunteer —please mulch your garden!

5. Starting too Big—or too Small
I love the advice to just start and grow something—even if that is just a single tomato in a pot. But unfortunately, this can also lead to frustration. Worse yet, it can make people shake their heads, declare they don’t have a green thumb, and give up.
On the other end, people can go a little overboard and build a massive first garden—and they quickly get overwhelmed.
These are both common gardening mistakes. And while it’s possible to make either work, I see far too many people getting frustrated and quitting.
So what should you do?
I can hear the question in your mind.
Okay, I can understand why starting too big might be a problem. But too small?
But here’s the thing.
When you only plant a single plant, that plant has to go it alone. All plants naturally grow in communities with other plants.
The plants in these communities support each other through a variety of means, but at the most basic level, it’s the simple fact that they support more life.
A garden made up of strong communities of life is a more resilient garden.
If you only have space for a small container garden, then please get the biggest container possible.
And here’s another reason. The smaller the container, the more it will be impacted by both heat and cold. This will mean you will have to water your plants far more often and protect them more carefully from frosts.
When I was growing food on an apartment balcony, I used 2 containers side-by-side, that each had a mix of peas, greens, herbs and flowers. These containers weren’t very big, but they were big enough to support their own little ecosystem.
Keeping this sort of mix of plants alive is actually much easier than growing a single tomato in a single pot.
But on the other end of the spectrum is the massive first garden filled with every type of vegetable you can image.
If you’re just starting out, then please start with a nice, moderately-sized garden—even a simple 10 x 10 foot (3 x 3 meter) garden can let you grow a lot of food.
Then make sure to start with a small number of vegetables—say peas/beans, some greens like lettuce or chard, a couple tomatoes, and a single zucchini.
Add some flowers like alyssum or nasturtiums and your garden will be off to a great start.
Just don’t forget to mulch it!
By avoiding the common gardening mistake of starting too big—or too small—you will make your life easier and save yourself from getting frustrated and giving up.
To easily fit your vegetables into your new modest garden, I recommend checking out the great book Square-Foot Gardening by Mel Bartholomew. This book will walk you through the spacing requirements for most vegetables, which will help you plant your new garden.
Gardening Doesn’t Have to Be Hard
I want to end this blog post with a final tip. Your garden isn’t a farm, and unless you’re trying to sell your produce, you shouldn’t treat it like one.
Far too much of the advice out there for growing food is based on maximizing harvests in the short run regardless of the negative impacts.
A market garden is very different from your kitchen garden, and you don’t need a massive, blue ribbon-winning tomato.
Your goal should be a garden that provides food for you and your family and that fits within your busy schedule.
When you mulch your vegetables, limit your watering, and aim for balance with pests you will have space to relax and slow down.
This will give you time to observe your garden and learn. In the long run, that, more than anything, will make you a better gardener.
You will make mistakes, but I hope you can now avoid the common gardening mistakes covered in this post. Just don’t let the mistakes you do make keep you from moving forward. Treat your mistakes as learning opportunities instead.
I’ve made a number of mistakes over the years, and I know I’ll make more in the future. But every time I do, I become a better gardener.
