Roses are mainly cultivated for their beautiful flowers. It's all the more annoying when the rose bush doesn't bloom.
Too much moisture prevents the rose from blooming
Unsuitable location / too humid weather
A common reason for the lack of flowering is a wrong location. Roses only bloom profusely when they feel good - and they do that above all in a sunny to partially shaded, not too hot, but airy place. The soil should be rich in nutrients, well drained and neither too firm nor too sandy. Before planting, it is advantageous to dig up the soil deeply and loosen it properly. In addition, the “queen of flowers” needs a lot of space, she is reluctant to compete with other plants. Therefore, you should definitely keep to the recommended planting distances! In addition to these reasons, the cause can also be a soil that is too moist (e.g. due to poor drainage) or wet, rainy weather that has lasted for weeks.
Roses must not follow roses
Under no circumstances should you plant roses in a location where a rose plant has previously stood. This rose will most likely grow very poorly and/or not bloom. The concrete reason for this "rose tiredness" of the soil has not yet been researched, but you can counteract this by replacing the soil.
Incorrect care or cut
Incorrect care can also lead to the rose not blooming. Roses need a lot of water - even if they don't necessarily like it wet - and, as they are heavy feeders, regular fertilization. You should water your roses vigorously, especially just before flowering, so that the flower does not let the buds dry out due to a lack of water. When fertilizing, make sure not to use too much nitrogen fertilizer - a lot of nitrogen encourages the plant to grow vigorously, but prevents flowering. You can also fall into many a trap when it comes to pruning, because many an uninformed gardener has accidentally cut off the flowering shoots in spring when roses bloom on perennial shoots.
pests or fungi
Especially if the rose has numerous buds that don't want to open but seem to be rotting, there is often either an infection with various possible fungi or a pest infestation behind it.
tips
Before you start looking for the cause and possibly transplant your rose completely unnecessarily, you should find out the specific type or variety of your rose. Some roses do not bloom on young shoots, but only on perennial wood. If you have caught such a rose, you only need to be patient for two to three years, then your rose will bloom.
