Gardening enthusiasts can transform their flower beds without spending a penny, according to a flower expert.
With over 35 years of experience, the expert explained how common kitchen waste can provide essential nutrients for healthier blooms.
Flower expert David Denyer said: "Healthy flowers start with good access to the nutrients plants need during their growth and blooming phases."
His four simple tips use items most households already have, offering a cost-effective alternative to commercial fertilisers.
The expert recommended eggshells
GETTYBanana peel power
Banana peels offer a natural potassium boost that supports nutrient movement and water regulation in flowering plants.
David said: "Simply bake your banana peels at a low temperature for a few hours, then either blend or grind them into a fine powder."
This powder can be mixed directly into soil, providing a slow release of nutrients. It's particularly beneficial for popular garden flowers like dahlias, calendula and cosmos, helping them develop stronger blooms.
Tea leaves for acid-loving plants
Used tea leaves provide a triple nutrient boost of nitrogen, phosphorus and potassium to support healthy growth and vibrant flowers.
The expert continued: "They contain small amounts of nitrogen, phosphorus, and potassium, which support healthy growth and flowers, but they also slightly lower the soil pH."
This makes them ideal for acid-loving plants like roses, hydrangeas, and azaleas, helping to deepen petal colour. Simply sprinkle damp tea leaves directly onto soil and water them in, ensuring they're free from milk or sugar to avoid attracting pests.
Eggshell calcium solution
Crushed eggshells provide calcium that strengthens flower stems and petals, but require proper preparation. David added: "A better method is to grind them into a fine powder and soak them in vinegar for 24 hours."
This creates calcium acetate, which plants can absorb more easily than raw eggshells. Once the fizzing stops and the solution cools, pour it around the base of your flowering plants.

Pulse water for soil health
The water used to rinse dried pulses like lentils and chickpeas offers another free plant nutrient source.
David explained: "It contains natural starches and minerals from the legumes, which feed the helpful microbes in your soil." These microbes help unlock phosphorus and potassium that plants need for healthy flowering.
For best results, use the rinse water the same day you collect it rather than storing it. This simple practice transforms what would normally be waste into a "gentle, nutrient-rich drink" for your garden.
