Gardening myths

Written by:

Whether you spend large or small amounts of time in the garden, you probably aren’t aware that there are many myths about gardening.

From not watering your plants enough to thinking seaweed is a fertiliser, these myths can ruin your garden and waste your time and money.

We asked Yates Horticulture Consultant, Angie Thomas, to help debunk some of the most common gardening myths so that you can get the most out of your garden.

Angie’s top 10 gardening myths debunked:

Myth no.1: You don’t need to feed Australian native plants

Always choose a fertiliser that is suitable for native plants. Apply around the root zone at the recommended rate and then water in well.

Myth no.2: Kill weeds with salty or boiling water

Both salty and boiling water can also harm beneficial earthworms and soil microorganisms (and boiling water can be dangerous to carry around the garden!).

Myth no.3: Drought tolerant plants don’t need watering

Newly planted plants should be watered regularly for several weeks or months to encourage strong early root development. Once they’re established, watering can be cut back, but not eliminated.

Myth no.4: There are indoor plants that can grow without light

Some plants will tolerate lower levels of light or will grow well with artificial lighting, but they still need some light. Plants like mother-in-law’s tongue, devil’s ivy and cast iron plant are great choices for dimly lit spots.

Myth no.5: Putting a layer of gravel in the bottom of pots helps drainage

Before the introduction of good quality potting mixes, it was recommended that pieces of broken pots or large gravel be placed in the bottom of pots. This is no longer necessary (and can actually contribute to drainage problems) if the pot has good drainage holes and the potting mix used is of a high standard.

Myth no.6: Seaweed is a plant food

Seaweed is only a tonic, that does not provide plants with the complete range of nutrients they need for strong, healthy growth (nitrogen, phosphorus and potassium). It’s important to feed plants with a ‘complete’ plant food that contains these three nutrients.
