The hydrangea is probably the most popular plant in European gardens. Of course, this has a lot to do with the inflorescence of this special bloomer. Nowadays there are hydrangeas in all kinds of colors and amount of flowers. A hydrangea not only belongs in every garden, but is always an asset to a terrace or balcony. How do you care for a hydrangea? When should you fertilize a hydrangea?
Caring for a hydrangea is not really that difficult, but you should pay attention to a few things and sort them out before planting. Good soil, timely pruning and sufficient water are important. Protection against late night frost is also a must, otherwise you run the risk of getting fewer flowers afterwards. You can read everything about fertilizing below. If you are going to plant a hydrangea, you can do this in a pot or in the ground. Remember that the plant must get enough sun otherwise it will not flower profusely. If the hydrangea is in full sun, it needs regular extra water. Before planting, always place the root ball in a bucket of water for a few minutes. That way it can suck up well.
Fertilize hydrangea, when and how?
If you want to enjoy that flower splendor of your hydrangea every year, fertilizing is necessary. When? Fertilize the hydrangeas at the end of March or early April, immediately after you have pruned the plants. You can choose between special hydrangea fertilizer or regular organic fertilizer. Organic manure is of animal or vegetable origin and also has sufficient nutrients and trace elements. Think of dried cow manure or old stable manure. The fertilizer works for about 3 months. Halfway through the summer, the hydrangeas are ready for a new portion of fertilizer. If you use hydrangea fertilizer, check the packaging for the correct amount.
With organic fertilizer you will eventually gain experience with the right amount. If you forget to fertilize the hydrangeas in the summer, you will notice this because the plants will look ‘tired’. The leaves then become dull green or yellowish. Then you should use fast-acting hydrangea fertilizer. It contains a lot of magnesium and iron. That is exactly what the plants have missed if the summer fertilization is forgotten. Applying fertilizer to a hydrangea is also important during this period.
