Gardening Hacks to Avoid: Expert Advice for Optimal Plant Health

In the digital age, gardening “hacks” promising to enhance plant growth and save time and money abound. However, according to seasoned gardening professionals, these hacks may not always live up to their claims.

Debunking Common Gardening Myths

We consulted three experts to identify the top gardening “hacks” to avoid. Their insights may surprise you, as they range from ineffective to potentially harmful:

Plant Drainage: Avoid Rocks at the Bottom of Pots

A widespread misconception is that adding a layer of rocks or pebbles at the bottom of plant pots improves drainage. However, this practice can actually hinder drainage, especially in pots without drainage holes.

“The rocks don’t aid drainage and can even decrease it if the layer is too thick,” explains Justin Hancock, a certified horticulturist at Costa Farms.

Instead, fill pots to the top with the chosen potting medium and opt for pots with drainage holes, especially for outdoor plants. To enhance drainage further, incorporate additives like perlite, pumice, or sand.

For ceramic planters lacking drainage holes, consider DIY methods to add them.

Weed Control: Avoid Landscape Fabric in Flower Beds

Landscape fabric is commonly used to suppress weeds in flower beds, but Mary Phillips, head of native plant habitat strategy at the National Wildlife Federation, advises against it.

“Made from synthetic materials, landscape fabric is not sustainable or beneficial for soil health,” Phillips says.

Instead, opt for organic mulches like shredded leaves or bark. Implement strategic planting techniques to prevent weeds, such as spacing plants closely or using living groundcovers between shrubs and trees.

Seed Starting: Avoid Planting Seeds in Eggshells

Using empty eggshells to start seedlings may seem eco-friendly and convenient, as they can be planted directly in the ground. However, Carrie Spoonemore, co-creator of the gardening app From Seed to Spoon, cautions against this practice.

“Seeds planted in eggshells may lack adequate space and drainage for healthy root development,” Spoonemore explains.

Eggshells also decompose slowly in the soil, inhibiting root growth and delaying the release of nutrients. Additionally, improperly cleaned eggshells could introduce harmful bacteria to seedlings.

Reuse eggshells by crushing them and adding them to compost or garden soil to provide calcium and other nutrients.

Homemade Fertilizers: Use with Caution

Homemade fertilizers and pesticides can be tempting, but Hancock advises against relying solely on them.

“While it may seem convenient or environmentally friendly, homemade products can be ineffective or even harmful to plants,” Hancock says. “They may lack essential nutrients or contain forms of nutrients that plants cannot utilize.”

Instead, determine the specific soil conditions and nutrient requirements of your plants and use proven, high-quality fertilizers or soil amendments. If you choose to experiment with homemade solutions, use them sparingly alongside commercial products.

Sustainable Gardening Practices

Beyond avoiding ineffective or harmful hacks, embrace sustainable gardening practices to promote plant health and environmental well-being:

• Organic Mulches: Use organic mulches like shredded leaves or bark to conserve moisture, suppress weeds, and improve soil health.
• Living Groundcovers: Plant low-growing groundcovers between larger plants to prevent weed growth and enhance soil stability.
• Composting: Create your own nutrient-rich compost by composting kitchen scraps, yard waste, and eggshells.
• Water Conservation: Implement water-saving techniques like drip irrigation and rainwater harvesting.
• Native Plants: Choose native plants that are adapted to your local climate and require minimal maintenance.

By avoiding common gardening pitfalls and adopting sustainable practices, you can cultivate a thriving and healthy garden.
