Gardeners looking to boost their plants without spending a fortune on chemical fertilisers can turn to common household products, according to Jason White, founder and CEO of All About Gardening. He suggests three natural methods to fertilise plants for “practically free”.
Kitchen scraps, including fruit and vegetable peels, are a “crucial” way to feed plants. White told Express.co.uk: “Kitchen scraps in general are healthy and practically free fertiliser when added to the compost. They are packed with a lot of nutrients from the varying items in it.” Banana peels, rich in potassium, calcium and phosphorus, are especially beneficial for fruit trees and flowering plants like roses. Simply dig a hole, dump the peels in and cover with soil.
Eggshells are another effective fertiliser. White said: “Adding crushed egg shells to the garden soil at least once a week will provide a steady source of calcium to make plants thrive.” To prepare, grind them with a mixer or mortar and pestle and till into the soil. Since eggshells take months to break down, it is best to add them in autumn.
Used coffee grounds are also recommended for fertilising soil and providing antioxidants. White explained: “It contains a ton of plant-healthy nutrients such as potash, phosphoric acid, and nitrogen.” Coffee grounds are particularly good for fruit trees, evergreens and roses. They lower soil pH if unwashed, and add organic matter to improve water retention, aeration and drainage.
