Hydrangeas fascinate with magnificent flowers and are therefore among the favorite flowers of many hobby gardeners. The regular supply of important nutrients is crucial for the plant to show its best side. It is therefore important when and how to fertilize the magnificently flowering hydrangeas. Did you know that you can fertilize hydrangeas with coffee grounds? It’s one of the ways to nourish the elegant beauties. Learn how below.
Fertilize hydrangeas with coffee grounds – how does that work?
Hydrangeas have some special requirements
The plant, which is still known as the farmer’s hydrangea, blooms from June to September, depending on the variety. If the flowers are planted in the right place, they really don’t need anything special other than enough water and nutrients to bloom beautifully. The hydrangea, as the plant’s scientific name is, likes a spot in partial shade. A nutrient-rich and non-compacted soil is best for the hydrangea.
The hardy beauty usually doesn’t need a lot of pruning to get it blooming again the following summer. But there are varieties that tolerate a strong pruning.
As a bog plant, hydrangea does well in acidic soil. Consequently, one must use fertilizers that lower the pH of the soil. The explanation is this: the low pH facilitates the all-important absorption of nutrients.
Nitrogen, phosphate and potassium are essential nutrients for hydrangeas. A high proportion of trace elements such as iron, magnesium, sulfur and zinc is also a prerequisite for the correct growth of hydrangeas and also contributes to the good resistance of the plant.
Also fertilize the potted plants with coffee grounds
How often the hydrangea needs to be fertilized depends on the location, the soil conditions and the hydrangea species itself. The hydrangeas in the garden as well as those in the bucket need enough “feed”. Nutrients are less in the pot and regular fertilization is life-saving. So keep in mind that potted hydrangeas need more fertilizer than those in the garden.
The fertilizing time is between March and August. Then you have to give fertilizer once or twice a week. In late summer you should avoid it. Otherwise the shoots will become soft and sensitive to frost. If that seems too complicated, you could use long-term fertilizers and fertilize less often. Even after rainfall it is advisable to give some fertilizer.
Soil conditions are very important for the growth and flowering of hydrangeas
Fertilizing Hydrangeas With Coffee Grounds – Why Is This A Good Fertilizer For These Plants?
A nitrogenous fertilizer that is low in phosphate is quite suitable for the hydrangea. That’s why people like to use the special hydrangea fertilizer. Some home remedies are also suitable for supplying the plant with nutrients. In addition to leaf compost, needle compost and horn meal, coffee grounds are one of the home remedies that are considered an effective fertilizer for hydrangeas. The coffee grounds make for a more acidic, fertile soil. This is generally a good fertilizer for plants that need an acidic and humus-rich soil.
Coffee grounds are an ideal fertilizer for hydrangeas because they have a very high nitrogen content. The residual product when using classic filter coffee machines is also particularly rich in potassium and magnesium. The disadvantage of coffee grounds as a fertilizer is that they cannot keep up for long.
How do you actually use the coffee grounds as fertilizer? Simply sprinkle a thin layer of coffee grounds in the root area and you’re done! But it is very important that it is well cooled and dry.
interesting to know: The caffeine contained in coffee turns the coffee grounds into an effective protection against many pests such as snails.
