Peace lilies can be tricky to keep happy. However, this common food scrap could help boost your blooms and keep your plant thriving
Peace lilies, with their striking white blooms, can transform any room into a real head-turner – yet they’re notoriously fussy. Getting them to thrive and flower requires a delicate touch and some specialist know-how.
These temperamental plants can struggle with poor lighting, low humidity, or watering mistakes, leaving them looking droopy and devoid of flowers. But the key to unleashing their full glory might be hiding in your kitchen bin.
Certainly, regular watering and keeping humidity high are crucial for peace lilies, yet your daily coffee habit could be concealing the answer to their success. Those spent coffee grounds you throw away each morning are actually brimming with nitrogen, an essential nutrient that fuels plant growth and keeps leaves lush and vibrant.
Yet there’s more to it than just nitrogen. Coffee grounds can also tweak your soil’s pH level to exactly what peace lilies crave, reports the Express.
Because of coffee’s natural acidity, mixing grounds into the compost creates the perfect growing environment, delivering multiple advantages in one simple step.
David Denyer, an experienced horticulturist from Eflorist, emphasises that your morning cuppa’s leftovers serve a double purpose – they energise your plants while keeping pests at bay. David said: “You swear by your morning cup of coffee, but some plant pests shudder at it.
“So, don’t toss those used grounds – they’re a free, year-round plant food that gives your indoor plants a nutrient boost, improves your soil, and may even deter insects and slugs.”
Making the most of your leftover grounds couldn’t be simpler – just mix a spoonful with cold water and pour it directly onto the soil. This nifty trick doesn’t just feed your plants; it also works wonders for soil structure and moisture retention, helping it to soak up water and nutrients far more effectively.
There is a catch, however – plant lovers must be careful not to go overboard. While you might get through several cups a day, your peace lilies need considerably less caffeine in their lives.
Try to fertilise roughly once a month, as applying too much risks making the soil excessively acidic and nitrogen-heavy, which can cause serious harm to your plants.
There is one further crucial point worth bearing in mind – only ever use grounds that have already been brewed.
Fresh coffee grounds still contain high levels of caffeine, which can actually hinder root and shoot growth in plants and stop those gorgeous blooms from appearing altogether.
