Juicy, sweet and easy to grow, raspberries are among the most popular summer fruits, suitable for any size garden and even containers if you choose a compact variety. They’re considered difficult to grow primarily because they have specific soil, light and moisture needs.
They’re also susceptible to pests and diseases, as well as requiring annual pruning and support for taller varieties. If you’re struggling to grow fruits or your raspberry bush is producing small berries, try adding one item to the soil.
Coffee grounds can be a beneficial fertiliser for raspberry bushes. They provide nitrogen and vitamins which support healthy growth, especially in acid-loving plants like raspberries.
Whilst they should be used in moderation, adding them to the soil just before berries appear is considered to be extremely beneficial.
Coffee grounds make an excellent addition to compost, which can then be used to amend the soil around raspberry bushes.
They are also great at improving drainage, making it easier for roots to grow and absorb nutrients.
To use coffee grounds, simply add them directly around the base of the bush, but in moderation.
Additionally, if you have a compost pile, it can be added to this and then used around the bush.
Apply them in spring or early summer before the raspberries begin to ripen, but do not use them after September.
This is because they can contribute to excessive nitrogen, which can weaken the plants before winter.
Make sure to avoid using flavoured coffee grounds, as these may contain additives that could harm plants.
Other plants which may benefit from being fed coffee grounds include blueberries, rhododendrons and roses.
Some vegetables may also produce better results with the leftovers, such as carrots, peppers and potatoes.
