Common Methods with No Benefit
Many gardeners have inherited traditional gardening tips from their parents or grandparents. Back in the day, people used what they had on hand, like eggshells, to improve their soil. While some of these methods are effective, others are simply gardening myths that don’t deliver the results they promise. Let’s explore some common fertilizer myths and uncover the truth!
Check out our video where Tricia explains more about these myths.
Myth 1: Beer is a Great Fertilizer
Beer is mostly water, contains sugars, and hosts natural microorganisms—three things that seem good for plants, right? Not quite. While beer won’t harm your plants, it’s an expensive and ineffective way to hydrate them. The sugars and yeast in beer don’t provide the nutrients plants need, and alcohol can even be harmful. Save the beer for your garden parties and opt for proven fertilizers to nourish your soil instead.
Myth 2: Burying a Banana Peel Boosts Potassium
Bananas are rich in potassium, so it seems logical to use banana peels to enrich your soil. However, the potassium in banana peels isn’t readily available to plants and can attract pests like rodents and insects. Instead, toss the peels into your compost bin or worm bin for better results.
Myth 3: Coffee Grounds Lower Soil pH
Coffee grounds are slightly acidic, leading many gardeners to believe they can lower soil pH for acid-loving plants like blueberries. However, used coffee grounds have minimal effect on soil pH and primarily act as organic matter. For better results, add coffee grounds to your compost pile and use specialized acid-loving fertilizers for your plants.
Myth 4: Container Plants Need Fresh Soil Every Year
While it’s true that container plants require fresh nutrients and occasional soil replenishment, replacing all the soil every year isn’t necessary. Instead, you can top-dress your container plants with a balanced fertilizer to give them a nutrient boost. Change out the soil only when repotting into a larger container or when the existing soil is no longer healthy.
Additional Fertilizer Myths
Myth: Fertilizer Fixes All Plant Problems
Fertilizers address nutrient deficiencies, but they won’t solve issues caused by pests, diseases, or improper watering. Identifying the root cause of a problem is essential to providing the right solution.
Myth: Organic Fertilizers Work Instantly
Unlike synthetic fertilizers, organic options release nutrients slowly as they break down in the soil. While this is beneficial for long-term soil health, it’s not ideal for addressing immediate deficiencies. Combining organic and synthetic fertilizers can balance immediate and sustained needs.
Tips for Effective Fertilizer Use
- Test Your Soil: A soil test kit can help you determine your soil’s nutrient levels and pH before applying fertilizer.
- Follow Application Rates: Over-fertilizing can harm plants and the environment. Stick to recommended rates.
- Time it Right: Apply fertilizers during active growth periods for best results.

But burying banana peels in the garden provides fun food for the worms that roam there. They told me so. And then they’ll poop out good fertilizer, though you won’t know exactly where it is. If you want it somewhere specific, you’ll have to talk it over with the worms. :)
1. While I’ve never claimed to know why it works (I’ve speculated), I have found banana peels to help with aphid issues. I don’t know if it’s the potassium in the peels or if it’s simply some bug killer that was used on the bananas, but I’ve seen a very definite impact on aphid problems by burying a peel or two in the hole when I plant my tomatoes and peppers. Give it a try.
2. In terms of changing out container soil, I think that’s necessary for some people because they get too carried away with fertilizer or other such substances. If the soil is properly maintained, then yes, they may not need to change it out every year, but that very easily may not have been the case – there could even have been issues with watering that resulted in a buildup of salt in the soil. The change out could also be good where crop rotation isn’t an option and they’re planting something that is overly sensitive to a lack of rotation.
What type of fertilizer for my perennial lilacs, gladiolus and iris?
Kojo, you should use a fertilizer with more phosphorus, that is for buds and blooms.
