Gardeners looking for a natural way to boost their lavender plants need look no further than their fruit bowl, according to experts. Banana peels offer a rich source of potassium, a vital nutrient for all lavender varieties.
Whether you're growing English lavender (Lavandula angustifolia) or French lavender (Lavandula dentata), these plants require specific nutrients to thrive and display their full potential.
Potassium stands out as an essential element for lavender's health and vigour, making banana peels an inexpensive and accessible option for garden enthusiasts.
Writing on behalf of House Digest, Theresa Cramer wrote: "Potassium aids in root growth, which boosts plants' resistance to droughts.
Plants lacking sufficient potassium often exhibit stunted growth

"Some gardeners use it to help their lavender through winter weather. Many gardeners swear that it helps lavender grow taller and produce more flowers."
Studies have shown that potassium aids in germination and growth, helping lavender plants grow taller and produce more abundant flowers.
Plants lacking sufficient potassium often exhibit stunted growth and smaller yields, according to scientific findings.
The nutrient also promotes root development, which significantly enhances lavender's resistance to drought conditions.
Additionally, potassium reduces water loss and supports photosynthesis, crucial processes for plant health.
These benefits collectively improve lavender's resilience during stressful periods, particularly harsh winter weather.
Many gardeners specifically apply potassium-rich amendments to help their lavender survive colder months.
In terms of application, experts recommend cutting peels into smaller pieces, washing them, and allowing them to air-dry for approximately three days to prevent mould issues.
Once dried, insert the pieces one or two inches below the soil surface around the base of your lavender plants.
Theresa noted: "The key to success is ensuring that potassium is available within the plant's root zone, as it tends not to venture far from where it's applied. You can repeat this process as often as once a month".
If you have more banana peels than garden space, composting offers an excellent alternative.

Banana peels are an inexpensive and accessible fertiliser for gardeners
GETTY
Home composting allows you to transform excess banana peels into nutrient-rich soil amendments.
The potassium from the peels will be preserved in your compost, along with various nutrients from other kitchen and garden waste. This creates a balanced fertiliser for future use in your garden.
Some gardeners note potential drawbacks to using banana peels directly as fertilisers, particularly for houseplants.
Therefore, gardeners are encouraged to do their research before applying this technique to different plant varieties.
