Summer has arrived, and gardeners are seeking ways to maintain healthy plants despite the heat. Drought and root stress are common challenges, but a simple kitchen staple can help. Former royal gardener Jack Stook, speaking on behalf of Coffee Friend, recommends reusing coffee grounds to protect gardens and deter pests.
Coffee Grounds as a Pest Deterrent
Sprinkling coffee grounds around bird feeders can repel squirrels due to the strong smell. Stook notes that this method can be effective, but warns against overuse. Too many grounds can turn into a sludgy mess when wet.
Benefits for Soil and Compost
Coffee grounds break down well in compost, enriching the mix. They can also be added directly to garden beds, acting as a mulch that improves soil structure. However, because coffee is acidic, it is best suited for ericaceous plants such as rhododendrons, azaleas, and hydrangeas.
Stook advises against using large quantities on plants that prefer neutral or alkaline soil. Most garden soil can tolerate small amounts, but for heavy applications, stick to acid-loving plants. Otherwise, dispose of grounds in the compost bin.
This simple, eco-friendly tip helps gardeners keep pests at bay while nourishing their plants naturally.
