When it comes to gardening, much of what we know spreads through word of mouth – parents teaching their children, or friends and neighbors sharing their favorite gardening tips. While this is a great way to learn to grow, it also means that there are plenty of myths about the best ways to care for the plants in our gardens.

Here’s a look at some of the most common gardening myths and whether or not they hold any truth.

Myth 1: All Vegetables Need Full Sun.

The common belief is that vegetables need full sunlight from dawn till dusk. However, most vegetables will do fine with eight hours of sunlight per day. Some, such as eggplants, squash, peppers, and tomatoes, will do well with six hours of sun, while crops like onions, carrots, peas, broccoli, and cauliflower will thrive on even less.

Myth 2: You Can Only Divide Perennials in the Spring and Fall.

It’s true that spring and fall are the best times to divide perennials, but they’re not the only times you can do it. When you divide plants in the spring, they’ll have plenty of time to recover before the hottest part of the year. In the fall, plants will soon be going dormant, which means you won’t have to worry about providing shade or extra water for much more than a week or two. If you’d like to give summer transplanting a try, just remember that you’ll need to give them a little extra care. Keep your transplants well watered and if necessary, provide them with some protection from the worst of the summer heat until they’re established.

Myth 3: You Should Change Your Potting Soil Every Year.

Some gardeners worry that potting soil only contains enough nutrients to keep plants healthy for one growing season. However, most types of potting soil will stay rich enough for at least a year or two. If you’re worried that your old potting soil is running low on nutrients, simply work a few handfuls of compost into the pots at the start of each year to keep your plants going strong. The only time you need to worry about replacing potting soil entirely is if you suspect a soil-borne disease problem.

Myth 4: Before Planting Annuals, Pinch the Blooms Off.

This myth stems from a very real phenomenon called transplant shock, which happens when you disturb or damage the roots of transplanted annuals and perennials. You can avoid transplant shock by trimming away the blooms and a large portion of the foliage so that the plant can devote more energy to rebuilding its root system. The problem is that many gardeners believe that newly purchased annuals and perennials should be pinched or pruned before planting. However, the potted plants from your local garden center should have a strong, healthy root system. Pinching the blooms from pots of pansies and petunias doesn’t encourage growth – it just means that you’ll wait longer for new blooms to appear.

Myth 5: Plants Rated for Extreme Hardiness Zones Will Thrive Anywhere.

So you’re a Zone 5 or 6 gardener, and you’ve just spotted a lovely perennial that is rated for Zone 2 temperatures. That means it should not only survive but also thrive in your climate, right? Not necessarily! No matter what perennials you choose, they all have a variety of needs – not just temperature, but also soil type, water requirements, humidity, sunlight, and more. Some of those super-hardy Zone 2 or 3 perennials may not survive in Zone 7 simply because they require ground temperatures to drop extremely low, or because they need a longer winter rest period. Plants that thrive in Arizona may not survive in Florida because even though the temperatures are similar, there are vast differences in soil structure and humidity.

Myths are almost as plentiful as weeds in the gardening world. Put these myths to rest so that you can save money, plant with greater flexibility and enjoy healthy, happy gardens!
