SPRING brings longer days, warmer weather, and bursts of colour everywhere, especially in the way of flowers. From cheery Daffodils and humble Bluebells to elegant Lilies - learn how to help your flowers look fabulous for longer. Whether you've picked up a treat at the local supermarket or you’ve been gifted a beautiful bouquet, it's devastating when your flowers die almost instantly. But don't despair because a flower expert has shared a secret that will help your flowers last longer. What is the secret ingredient? Elise Harlock, brand manager at Prestige Flowers, said: “Hydration is key for keeping fresh-cut lilies for longer but the acidity of the water is important, too. "A splash of lemon juice can lower the water’s pH which helps lilies absorb water easier and keep them vibrant for longer. “Lemon water is a healthy drink for humans but many don’t realise it can have benefits for flowers, too. "A vitamin C tablet crushed into the vase can also be effective.” If you haven't got a lemon lying around at home, you can pick one up for around 30p at your local supermarket. Most flowers absorb water more effectively in an acidic environment which helps them stay hydrated and fresher for longer and keeps bacteria growth at bay. What causes flowers to wilt? “One of the biggest culprits behind wilting flowers is bacteria as it can block flower stems’ vascular systems. "This prevents water and nutrient uptake and causes petals to droop and leaves to start yellowing.” Elise added: “Lowering the pH keeps vase water clearer, the growth of harmful bacteria is reduced, keeping stems clear and expanding your flowers’ lifespan.” Elise also recommends refreshing the water in the vase every two or three days and trimming stems at a 45-degree angle to improve water uptake. She added: “Direct sunlight can be too harsh on flowers, so if you want to keep your bouquet for as long as possible, place them somewhere cool and shaded. "Retrimming flower stems can also extend the life of your lilies. "Over time, the cut ends of blooms can become blocked by air bubbles which can block water and nutrients accessing the flower. “Trim half an inch off your stems after a few days to expose a fresh surface to absorb water.” Meanwhile, you can give your flowerbeds and lawn a spring spruce up without spending any extra money. Instead of investing in bags of pricey fertiliser, simply repurpose an item that's already in your fridge. However, with the sun shining, many people might begin to notice weeds growing on their patios. But you don’t have to fork out on expensive products to get rid of them, as gardening fans have revealed a simple two-ingredient hack that they claim will make stubborn gravel weeds disappear. Even better, they say it works in less than 24 hours.
